Environmental pollution and degradation

<–2/”>a >The major causes of the Environmental Degradation are modern Urbanization, industrialization, over-Population Growth, deforestation etc. Environmental pollution refers to the degradation of quality and quantity of natural Resources.

Mahatma Gandhi’s principle of “enoughness” in his saying “the earth provides enough to satisfy every persons need but not for every person’s greed” According to World Commission on Environment and Development, Our Common Future (1987) , Sustainable Development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

It contains within it two key concepts:

the concept of needs, in particular the essential needs of the world’s poor, to which overriding priority should be given; and
the idea of limitations imposed by the state of technology and social organization on the environment’s ability to meet present and future needs.”

Environmental influences are important both at the prenatal and postnatal stages of Human Development. At the prenatal stage, when a fetus is in the mother’s womb, internal or external harmful agents, such as certain legal or illegal drugs, alcohol, lead and pollutants can harm the unborn baby’s development. The mother’s Nutrition, diseases and emotional Stress can also affect the development of the fetus.

The environment provides various resources to man-both renewable and nonrenewable. Renewable resources are those resources which are replenished easily over time, and hence can be used without the possibility of the resource becoming depleted or exhausted. Examples of renewable resources include trees in the forests, fishes in the ocean, etc. Non-renewable resources, on the other hand, are those resources which can get exhausted or depleted over time as they are used up. Examples of non-renewable resources include fossil fuels and Minerals like petroleum,natural gas, coal, etc. Thus these resources need to be used carefully, while keeping in mind the requirements of the future generations.

Economic Growth and Sustainability

Over-consumption has led to depletion of resources
Main environmental threats
- Depletion of resources
- Global Warming
- Expansion of waste arising from production and consumption
- Population pressure
- Pollution
- Loss of Biodiversity-2/”>Biodiversity and extinction of species.
Green NATIONAL INCOME Account
- Conventional National Income Accounting does not capture the environmental degradation due to production and consumption
- This omission leads to misrepresentation of improvements in social welfare
- Since there is no market for many environmental resources, it is difficult to place monetary values on them
- Index of Sustainable Economic Welfare: adjusts the national income to make an allowance for defensive spending (i.e. that incurred in cleaning up for pollution and other forms of environmental damage)
Economic Sustainability
- Calls for reforms in the manner that we conduct our economic activity
- Removing unfair trade barriers and subsidies that harm the environment
- Upholding the polluter pays principle
- Tax not on labour but on consumption <already there in the form of indirect taxes>
- Pricing products in terms of value they have deducted from the common natural base
- Increase resource productivity
Sustainable agriculture
- Use of practices and methods to maintain/enhance the economic viability of agricultural production, natural resource base, and other Ecosystems which are influenced by agricultural activities
- Minimizing the adverse impact on the Natural Resources base
- Flexible Farming Systems to manage the risks associated with Climate and markets

Ecological Sustainability

Sustainable forest management
- ‘Forest Principle’ adopted at the 1992 Rio Summit
- In 2007, GA adopted the Non Legally Binding Instrument on All Types of Forests. The instrument is the first of its kind and is committed to promote SFM by bringing all stakeholders together
- Ministerial Conference on Protection of Forests in Europe defined SFM as the attainment of balance between Society’s increasing demands for forest products and benefits, and the preservation of forest Health and diversity.
- Forest managers must assess and integrate a wide array of sometimes conflicting factors to produce Sound forest plans
- Ecosystems approachhas been adopted by the CBD. The CBD definition of Ecosystems Approach is known as the Malawi Principles.
- Ecosystems Approach is a strategy of management of land, water and living resources in a way that promotes conservation and sustainable use in an equitable way. Focused on use of scientific methodologies for each level of biological organisation and their interaction.
- SFM was recognised by the parties to CBD in 2004 to be a concrete means of applying the Ecosystems Approach to forest ecosystems
Objectives of SFM
- Maintain environmental stability through preservation of ecological balance that has been adversely affected due to the depletion of forest cover
- Preserve the natural heritage of the country
- Improve productivity of forests
- Protecting through cooperation with local communities on the principle of Joint Forest Management

The rapid pace of Population Growth has led to the excessive utilization of natural resources. Huge population also leads to huge production of wastes. The resultant outcomes are loss of biodiversity, pollution of air, water and Soil and increased pressure on arable land. All these have been putting great stress on the environment. If you take the case of India, it supports 17 percent of world population on just 2.4 per cent of the world land area.
The earth’s carrying capacity in terms of its food resource is approaching its limits. Oceanic supply of fish, rangelands which support Livestock, and the Hydrological Cycle to produce freshwater are strained. The backlog of unused agricultural technology is shrinking in industrial and developing countries alike, slowing the rise in cropland productivity. At the same time, soil erosion, Air Pollution, soil compaction, aquifer depletion, the loss of soil organic matter, and the waterlogging and salting of irrigated land are all slowing food production. At present, it appears that nothing can reverse the worldwide decline in grain output per person. The bottomline is that the world’s farmers can no longer be counted on to feed the projected additions to the present population. Attaining a humane balance between food production and population growth now depends more on family planners instead of farmers.
The Environment Protection Act is an important legislation that provides for coordination of activities of the various regulatory agencies, creation of authorities with adequate powers for environmental protection, regulation of the discharge of environmental pollutants, handling of hazardous substances, etc. The Act provided an opportunity to extend legal protection to non-forest habitats (‘Ecologically Sensitive Areas’) such as grasslands, wetlands and coastal zones.The Environment (Protection) Act was enacted in 1986 with the objective of providing for the protection and improvement of the environment. It empowers the Central Government to establish authorities charged with the mandate of preventing environmental pollution in all its forms and to tackle specific environmental problems that are peculiar to different parts of the country.
The Environment Protection Act is an umbrella legislation that consolidated the provisions of the Water (Prevention and Control of Pollution) Act of 1974 and the Air (Prevention and Control of Pollution) Act of 1981. Within this framework of the legislations, the government established Pollution Control Boards (PCBs) in order to prevent, control, and abate environmental pollution.
Under the EPA, Environmental Impact Assessment (EIA) Notification was introduced in 1994, it was modified in 2006 and the latest amendment was in 2009. Under the EIA it has become mandatory to seek environmental clearance for several activities and industries with the involvement of the public as per procedure.
Main Features of The Environment Protection Act are:-
i) Co-ordination of actions by the State Governments, officers and other authorities
ii) Planning and execution of a nation-wide programme for the prevention, control and abatement of environmental pollution.
iii) Laying down standards for the quantity of environment in its various aspects.
iv) Laying down standards for emission or discharge of environmental pollutants from various sources whatsoever. Provided that different standards for emission or discharge may be laid down under this clause from different sources having regard to the quality or composition of the emission lr discharge of environmental pollutants from such sources.
v) Restriction of areas in which any industries, operations or processes or class of industries, operations or processes shall not be carried out or shall be carried out subject to certain safeguards.
vi) Laying down procedures and safeguards for the prevention of accidents which may cause environmental pollution and remedial measures for such accidents.
vii) Laying down procedures and safeguards for the handling of hazardous substances.
viii) Examination of such manufacturing processes, materials and substances as are likely to cause environmental pollution.
ix) Carrying out and sponsoring investigations and research relating to problems of environmental pollution.
x) Inspection of any premises, plant, equipment, machinery, manufacturing or other processes, materials or substances and giving, by order, of such directions to such authorities, officers or persons as it may consider necessary to take steps for the prevention, control and abatement of environmental pollution.
xi) Establishment or recognition of environmental laboratories and institutes to carry out the functions entrusted to such environmental laboratories and institutes under this Act.
xii) Collection and dissemination of information in respect of matters relating to environmental pollution.
xiii) Preparation of manuals, codes or guides relating to the prevention, control and abatement of environmental pollution.

ENVIRONMENT POLLUTION
defined as ‘an addition or excessive addition of certain materials to the physical environment (water, air and lands), making it less fit or unfit for life’.
Pollutants are the materials or factors, which cause adverse effect on the natural quality of any component of the environment.
Classifications
1. According to the form in which they persist after release into the environment.
• Primary pollutants: These persist in the form in which they are added to the environment e.g. DDT, plastic.
• Secondary Pollutants: These are formed by interaction among the primary pollutants. For example, peroxyacetyl nitrate (PAN) is formed by the interaction of nitrogen oxides and hydrocarbons.
2. According to their existence in nature.
• Quantitative Pollutants: These occur in nature and become pollutant when their concentration reaches beyond a threshold level. E.g. carbon dioxide, nitrogen oxide.
• Qualitative Pollutants: These do not occur in nature and are man-made. E.g. fungicides, herbicides, DDT etc.
3. According to their nature of disposal.
• Biodegradable Pollutants: Waste products, which are degraded by microbial action. E.g. sewage.
• Non-biodegradable Pollutants: Pollutants, which are not decomposed by microbial action. E.g. plastics, glass, DDT, salts of heavy metals, radioactive substances etc
4. According to origin
• Natural
• Anthropogenic

AIR POLLUTION
aggravated because of four developments:
Increasing traffic, growing cities, rapid Economic Development, and industrialization
contamination of air by the discharge of harmful substances

Major air pollutants and their sources
1. Carbon monoxide (CO)
• It is a colourless, odourless gas that is produced by the incomplete burning of carbon – based fuels including petrol, diesel, and wood.
• It is also produced from the combustion of natural and synthetic products such as cigarettes.
• It lowers the amount of Oxygen that enters our blood. It can slow our reflexes and make us confused and sleepy.
2. Carbon dioxide (CO2)
principle greenhouse gas
3. Chloroflorocarbons (CFC)
• gases that are released mainly fromair-conditioning systems and refrigeration.
• When released into the air, CFCs rise to the Stratosphere, where they come in contact with few other gases, which lead to a reduction of the ozone layer that protects the earth from the harmful ultraviolet rays of the sun.

4. Lead
present in petrol, diesel, lead batteries, paints, hair dye products, etc.
affects children in particular. cause nervous system damage and digestive problems and, in some cases, cause cancer.

5. Ozone
• occurs naturally in the upper layers of the Atmosphere.
• at-the ground level, it is a pollutant with highly toxic effects.
• Vehicles and industries are the major source of ground-level ozone emissions.
• Ozone makes our eyes itch, burn, and water. It lowers our resistance to cold and pneumonia.

6. Nitrogen oxide (Nox)
• causes smog and Acid Rain. It is produced from burning fuels including petrol, diesel, and coal.
• Nitrogen oxide can make children susceptible to respiratory diseases in winters.

7. Suspended particulate matter (SPM)
• consists of solids in the air in the form of smoke, dust, and vapour that can remain suspended for extended periods
• The finer of these particles when breathed in can lodge in our lungs and cause lung damage and respiratory problems.

8. Sulphur dioxide (S02)
• a gas produced from burning coal, mainly in thermal power Plants.
• Some industrial processes, such as production of paper and smelting of metals, produce sulphur dioxide.
• a major contributor to smog and acid rain.
• Sulphur dioxide can lead to lung diseases

9. Smog
• a combination of the words fog and smoke. Smog is a condition of fog that had soot or smoke in it.
• interaction of sunlight with certain chemicals in the atmosphere.
• primary components of photochemical smog is ozone.
• Ozone is formed through a complex reaction involving hydrocarbons, nitrogen oxides, and sunlight. It is formed when pollutants released from gasoline, diesel- powered vehicles and oil-based solvents react with heat and sunlight from biofuels, the four most serious pollutants are particulates, carbon monoxide, polycyclic organic matter, and formaldehyde

Pollutants
i) Volatile organic compounds
The main indoor sources are perfumes, hair sprays, furniture polish, glues, air
fresheners, moth repellents, wood preservatives, and other products.

ii) Biological pollutants
It includes pollen from plants, mite, and hair from pets, Fungi, parasites, and some bacteria.
iii) Formaldehyde
Mainly from carpets, particle boards, and insulation foam. It causes irritation to the eyes and nose and allergies.
iv) Radon
It is a gas that is emitted naturally by the soil. Due to modern houses having poor ventilation, it is confined inside the house and causes lung cancers.

Fly Ash
Ash is produced whenever combustion of solid material takes place.
Composition
1. Aluminium silicate (in.large amounts)
2. silicon dioxide (Si02) and
3. Calcium oxide (Ca0).
Fly ash particles are oxide rich and consist of silica, alumina, oxides of iron, calcium, and magnesium and toxic heavy metals like lead, arsenic, cobalt, and coppers

Policy measures of MoEF:
• The Ministry of Environment and Forests vide its notification in 2009, has made it mandatory to use Fly Ash based products in all construction projects, road embankment works and low lying land filling works within 100 kms radius of Thermal Power Station.
• To use Fly Ash in mine filling activities within 50 kms radius of Thermal Power Stations.
• Arresters: These are used to separate particulate matters from contaminated air.
• Scrubbers: These are used to clean air for both dusts and gases by passing it through a dry or wet packing material.
Government Initiatives
(1) National Air Quality Monitoring Programme
In India, the Central Pollution Control Board (CPCB) has been executing a nationwide programme of ambient air quality monitoring known as National Air Quality Monitoring
Programme (NAMP).
The National Air Quality Monitoring Programme (NAMP) is undertaken in India
(i) to determine status and trends of ambient air quality;
(ii) to ascertain the compliance of NAAQS;
(iii) to identify non-attainment cities;
(iv) to understand the natural process of cleaning in the atmosphere; and
(v) to undertake preventive and corrective measures.
Annual Average concentration of SOx levels are within the prescribed National Ambient
Air Quality Standards (NAAQS).
National Ambient Air Quality Standards (NAAQS) were notified in the year 1982, duly revised in 1994 based on health criteria and land uses .
The NAAQS have been revisited and revised in November 2009 for 12 pollutants, which include. sulphur dioxide (S02), nitrogen dioxide (NO2), particulate matter having size less than 10 micron
(PM10),particulate matter having size less than 2.5micron (PM2.5), ozone, lead, carbon monoxide (CO), arsenic, nickel, benzene, ammonia, and. Benzopyrene.
Water Pollution
Addition of certain substances to the water such as organic, inorganic,
biological, radiological, heat, which degrades the quality of water so that it
becomes unfit for use.
Putrescibility is the process of decomposition of organic matter present in water by Microorganisms using oxygen.
Water having DO (dissolved oxygen) content below 8.0 mg/L may be
considered as contaminated. Water having DO content below. 4.0 mg/L is
considered to be highly polluted.
Water pollution by organic wastes is measured in terms of Biochemical Oxygen Demand-(BOD). BOD is the amount of dissolved oxygen needed by bacteria in decomposing the organic wastes present in water.
Chemical oxygen demand (COD) is a slightly better mode used to measure pollution load in water. It is the measure of oxygen equivalent of the requirement of oxidation of total organic matter (i.e. biodegradable and non- biodegradable) present in water.
A cripling deformity called Minamata disease due to consumption of fish captured from mercury contaminated Minamata Bay.
Water contaminated with cadmium can cause itai itai disease also called ouch-ouch disease (a painful disease of bones and joints) and cancer of lungs and liver.
The compounds of lead cause anaemia, headache, loss of muscle power and bluish line around the gum
Excess nitrate in drinking water reacts with hemoglobin to form non -functional met haemoglobin, and impairs oxygen transport. This condition is called methaemoglobinemia or Blue baby syndrome.
Over exploitation of ground water may lead to leaching of arsenic from soil and rock sources and contaminate ground water. Chronic exposure to arsenic causes black foot disease. It also causes diarrhoea,-peripheral neuritis, hyperkerotosis and also lung and skin cancer.
Soil Pollution
Industrial waste includes chemicals such as mercury, lead, copper, zinc, cadmium, cynides, thiocynates, chromates, acids, alkalies, organic substances etc
Four R’s: Refuse, Reduce, Reuse, and Recycle
Noise Pollution
Sound is measured in decibels (dB). An increase of about 10 dB is approximately double the increase in loudness.
A person’s hearing can be damaged if exposed to noise levels over 75 dB over a prolonged period of time.
The World Health Organization recommends that the sound level indoors should be less than 30 dB.
Ambient Noise Level Monitoring – Noise Pollution (Control and Regulation) Rules, 2000 define ambient noise levels for various areas as follows-
A. Industrial Area—75DB to 70Db (Day time-6am to 10pm and night time 10pm to 6am ..75 is day time and 70 is night time)
B. Commercial Area–65 to 55
C. Residential Area–55 to 45
D. Silence Zone– 50 to 40
• The Government of India on Mar 2011 launched a Real time Ambient Noise Monitoring Network.
• Under this network, in phase- I, five Remote Noise Monitoring Terminals each have been installed in different noise zones in seven metros (Delhi, Hyderabad, Kolkata, Mumbai, Bangalore, Chennai and Lucknow).
In Phase II another 35 monitoring stations will be installed in the same seven cities.
Phase III will cover installing 90 stations in 18 other cities.
Phase-III cities are Kanpur, Pune, Surat, Ahmedabad, Nagpur, Jaipur, Indore,
Bhopal, Ludhiana, Guwahati, Dehradun, Thiruvananthpuram, Bhubaneswar,
Patna, Gandhinagar, Ranchi, Amritsar and Raipur.
Silence Zone is an area comprising not less than 100 metres around hospitals, educational institutions, courts, religious places or any other t area declared as such by a competent authority.

RADIO ACTIVE POLLUTION
Non-ionising radiations affect only those components which absorb them and have low penetrability. They include short-wave radiations such as ultraviolet rays, which forms a part of solar radiation. Sunburns is due to these radiation Ionising radiations have high penetration power & cause breakage of macro Molecules
They include X-rays, cosmic rays and atomic radiations -(radiations emitted by radioactive Elements
Alpha particles, can be blocked by a piece of paper and human skin.
Beta particles can penetrate through skin, while can be blocked by some pieces of glass and Metal.
Gamma rays can penetrate easily to human skin and damage cells on its way through, reaching far, and can only be blocked by a very thick, strong, massive piece of concrete radium-224, uranium-238, thorium-232, potassium-40, carbon-14, etc.
The nuclear arms use uranium-235 and plutonium-239 for fission and hydrogen or lithium as fusion material
The radio nuclides with long half-time are the chief source of environmental radioactive pollution.

E — WASTE
E-Waste is not hazardous if it is stocked in safe storage or recycled by scientific methods or transported from one place to the other in parts or in totality in the formal sector. The e-waste can be considered hazardous if recycled by primitive methods
Survey was carried out by the Central Pollution Control Board (CPCB) during 2005
In India, among top ten cities; Mumbai ranks first in generating e-waste followed by Delhi, Bangalore, Chennai, Kolkata, Ahmadabad, Hyderabad, Pune, Surat and Nagpur.

SOLID WASTE
the discarded (abandoned or considered waste-like) materials does not include solid or dissolved materials in domestic sewage, or solid or dissolved materials in Irrigation return flows or industrial discharge s0 Conventional plastics have been associated with reproductive problems in both humans and wildlife.
Dioxin (highly carcinogenic and toxic) by-product of the manufacturing process is one of the chemicals believed to be passed on through breast milk to the nursing infant.
Burning of plastics, especially PVC releases this dioxin and also furan into the atmosphere.
Pyrolysis-It is a process of combustion in absence of oxygen or the material burnt under controlled atmosphere of oxygen. It is an alternative to incineration. The gas and liquid thus obtained can be used as fuels.

Waste minimization Circles (WMC)
helps Small and Medium Industrial Clusters in waste minimization in their industrial plants. assisted by the World Bank with the Ministry of Environment and Forests acting as the nodal ministry. being implemented with the assistance of National Productivity Council (NPC), New Delhi.
aims to realise the objectives of the Policy Statement for Abatement of Pollution (1992), which states that the government should educate citizens about environmental risks, the economic and health dangers of resource degradation and the real economic cost of natural resources.
BIOREMEDIATION
the use of microorganisms (bacteria and fungi) to degrade the environmental contaminants into less toxic forms.
Phytoremediation/”>Phytoremediation
is use of plants to remove contaminants from soil and water .
Rhizofiltration
• a water remediation technique that involves the uptake of contaminants by plant roots.
• used to reduce contamination in natural wetlands and estuary areas.,

Environmental pollution and degradation are two of the most pressing issues facing our planet today. Pollution is the contamination of the physical and biological components of the Earth/atmosphere system to such an extent that normal environmental processes are adversely affected. Degradation is the deterioration of the natural environment caused by human activities.

There are many different types of pollution, including air pollution, water pollution, soil pollution, noise pollution, Light pollution, thermal pollution, chemical pollution, nuclear pollution, marine pollution, land pollution, Ozone Depletion, acid rain, global warming, Climate Change, biodiversity loss, deforestation, Desertification, overpopulation, overconsumption, Waste Management, sustainable development, environmental protection, environmental activism, environmental law, environmental ethics, environmental economics, environmental engineering, environmental science, environmental health, environmental Justice, environmental sustainability, environmental stewardship, and Education/”>Environmental Education.

What is environmental pollution?

Environmental pollution is the contamination of the physical and biological components of the Earth/atmosphere system to such an extent that normal environmental processes are adversely affected. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Air pollution, water pollution, soil contamination, noise pollution and light pollution are some of the different types of environmental pollution.

What are the causes of environmental pollution?

The main causes of environmental pollution are:

Human activities: Human activities such as agriculture, Industry, transportation, and energy production are the main sources of environmental pollution.
Natural causes: Natural causes such as volcanic eruptions, forest fires, and Earthquakes can also cause environmental pollution.
Accidents: Accidents such as oil spills and chemical leaks can also cause environmental pollution.

What are the effects of environmental pollution?

The effects of environmental pollution can be both short-term and long-term. Short-term effects of environmental pollution can include respiratory problems, skin irritation, and eye problems. Long-term effects of environmental pollution can include cancer, birth defects, and reproductive problems. Environmental pollution can also have a negative impact on the environment, such as damaging ecosystems and reducing biodiversity.

What are the solutions to environmental pollution?

There are a number of solutions to environmental pollution, including:

Reducing our reliance on fossil fuels: Fossil fuels are a major source of air pollution. We can reduce our reliance on fossil fuels by using RENEWABLE ENERGY sources such as solar and wind power.
Improving Energy Efficiency: We can improve energy efficiency by using energy-efficient appliances and light bulbs.
Reducing waste: We can reduce waste by recycling and composting.
Protecting our forests: Forests play an important role in absorbing carbon dioxide from the atmosphere. We can protect our forests by planting trees and reducing deforestation.
Conserving water: Water is a precious resource that we need to conserve. We can conserve water by taking shorter showers, fixing leaky faucets, and watering our lawns less often.
Educating others about environmental pollution: We can educate others about environmental pollution by talking to them about the issue and sharing information about it.

What is the importance of environmental protection?

Environmental protection is important because it helps to protect our health, our environment, and our economy. Environmental pollution can cause a number of health problems, such as respiratory problems, skin irritation, and eye problems. Environmental pollution can also damage the environment, such as damaging ecosystems and reducing biodiversity. Environmental pollution can also have a negative impact on the economy, such as reducing tourism and damaging businesses.

What can I do to help protect the environment?

There are a number of things you can do to help protect the environment, including:

Reduce your energy consumption: You can reduce your energy consumption by turning off lights when you leave a room, unplugging appliances when you’re not using them, and using energy-efficient appliances.
Recycle: Recycling helps to reduce the amount of waste that goes into landfills. You can recycle paper, plastic, metal, and glass.
Compost: Composting helps to reduce the amount of waste that goes into landfills. You can compost food scraps, yard waste, and paper products.
Plant a tree: Trees help to clean the air and provide oxygen. You can plant a tree in your yard or in a public park.
