ENVIRONMENT POLLUTION 2

<–2/”>a >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 discharges0

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)

ENVIRONMENTAL IMPACT ASSESSMENT

Notification on Environmental Impact Assessment (EIA) of developmental

projects 1994 under the provisions of Environment (Protection) Act, 1986 making EIA mandatory for 29 categories of developmental projects. One more item was added to the list in January, 2000. environmental impact assessment statutory for 30 activities

Environment Impact Assessment Notification of 2006 has categorized the developmental projects in two categories, i.e., Category A and Category B

Ministry of Environment & Forests

‘Category A’ projects are appraised at national level by expert appraisal committee

India has constituted the State Level Environment Impact Assessment Authority (SEIAA) and State Level Expert Appraisal Committee (SEAC) to decentralize the environmental clearance process

The objective of EIA is to foresee and address potential environmental problems/ concerns at an early stage of project planning and design.

The EIA notification establishes four stages for obtaining Environmental Clearance.

Screening
Scoping and consideration of alternatives Baseline data collection
Impact prediction
Assessment of alternatives, delineation of mitigation measures and environmental impact statement
Public hearing
Environment Management Plan DECISION MAKING
Monitoring the clearance conditions

Screening- It is only for Categories B

Screening Criteria are based upon:

Scales of Investment; • Type of development; and, • Location of development

B1 Categories project require Environmental Impact Assessment while B2 category projects are exempted from EIA.

State Level Expert Appraisal Committee determine about project categories

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.

Air pollution is the contamination of the air by noxious gases, chemicals, particulate matter, and biological materials. Air pollution can cause respiratory problems, heart disease, and cancer. It can also damage crops and Ecosystems.

Water pollution is the contamination of water bodies, such as lakes, rivers, and Oceans, by harmful substances. Water pollution can cause fish kills, algae blooms, and other problems that can harm human health and the environment.

Soil Pollution is the contamination of soil by harmful substances, such as pesticides, herbicides, and heavy metals. Soil pollution can make the soil unusable for agriculture or other purposes. It can also contaminate groundwater and surface water.

Noise pollution is the unwanted or excessive Sound that can have harmful effects on human health and the environment. Noise pollution can cause hearing loss, Stress, and sleep problems. It can also disrupt wildlife and ecosystems.

Light pollution is the excessive use of artificial light at night. Light pollution can disrupt the natural cycles of plants and animals. It can also make it difficult to see stars and planets in the night sky.

Thermal pollution is the release of excess heat into the environment. Thermal pollution can cause changes in water temperature, which can harm fish and other aquatic life. It can also damage ecosystems.

Nuclear pollution is the contamination of the environment by radioactive materials. Nuclear pollution can cause cancer and other health problems. It can also damage ecosystems.

Chemical pollution is the contamination of the environment by harmful chemicals. Chemical pollution can cause cancer, birth defects, and other health problems. It can also damage ecosystems.

Plastic pollution is the contamination of the environment by plastic materials. Plastic pollution can harm wildlife and ecosystems. It can also take hundreds of years to decompose.

Marine pollution is the contamination of the ocean by harmful substances. Marine pollution can harm fish and other marine life. It can also damage coral reefs and other marine ecosystems.

Land pollution is the contamination of the land by harmful substances. Land pollution can make the land unusable for agriculture or other purposes. It can also contaminate groundwater and surface water.

Environmental pollution is a serious problem that can have a devastating impact on human health and the environment. It is important to take steps to reduce pollution and protect our planet.

There are many things that can be done to reduce pollution. Some of the most important steps include:

Reducing our reliance on fossil fuels
