The enhanced pace of developmental activities and rapid Urbanization have resulted in Stress on natural Resources and Quality Of Life. The trend of increasing pollution in various environmental media is evident from the deteriorating air and water quality, higher noise levels, increasing vehicular emission etc. Realising the urgent need for arresting the trend, Both Central and State Governments have adopted policy for Abatement of Pollution which provides for several mechanisms in the form of regulations, legislation, agreements, fiscal incentives and other measures to prevent and abate pollution. Further, realizing that conventional pollution control approach by treatment at the end of the pipe is not delivering the desired benefits in terms of resource conservation, the thrust has been shifted to pollution prevention and control through promotion of clean and low waste technology, re-use and recycling, natural resource accounting, Environmental Audit and Institutional and Human resource development.
Various techniques to control Air Pollution are:-
- Combustion:- is used for controlling those air pollutants that are in the form of organic gases or vapours. In this technique, the organic air pollutants are subjected to flame combustion technique (also known as catalytic combustion). In this technique, organic pollutants are converted into less harmful products and water vapour.
- Absorption:-is the most commonly used methods, especially for controlling emissions from small sources. It can be physical adsorption or chemisorptions.
- Fabric filters, or baghouses, remove dust from a gas stream by passing the stream through a porous fabric. The fabric filter is efficient at removing fine particles and can exceed efficiencies of 99 percent in most applications.
- Mechanical devices:-There are many mechanical devices that clean the air of pollutants either due to (i) gravity in which the particles settle down by Gravitational Force; or by (ii) sudden change in the direction of gas flow in which particles separate out due to greater momentum.
- Electrostatic precipitators:-is a particle control device that uses electrical forces to move the particles out of the flowing gas stream and onto collector plates.
Environment and human Health; Effects of pollutants on animals and Plants
Human beings are exposed to a variety of chemicals including industrial chemicals, pesticides, air pollutants, natural and man made toxicants etc in the environment through the skin, Respiratory System and gastrointestinal tract that can affect vital body systems such as pulmonary, reproductive and nervous and immune system. Dysfunction of these systems could have far-reaching consequences, which affect individuals and even their progeny from serious health ailments.
Air pollutants can be in the form of particulate matter which can be very harmful to our health. The level of effect usually depends on the length of time of exposure, as well the kind and concentration of chemicals and particles exposed to. Short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Others include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and Emphysema. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.

Human role in pollution control
Pollution is the introduction of contaminants into the natural environment that cause adverse change. 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 pollution.
Pollution is a major cause of Environmental Degradation and human health problems. It can cause respiratory problems, heart disease, cancer, and other health problems. Pollution can also damage Ecosystems and wildlife.
There are many ways to control pollution. One way is to reduce the amount of pollution that is produced. This can be done by using cleaner technologies, recycling, and reducing waste. Another way to control pollution is to clean up pollution that has already been produced. This can be done by using pollution control devices, such as scrubbers and filters, and by treating polluted water and air.
Governments can also play a role in controlling pollution. They can set standards for pollution levels, regulate industries that pollute, and provide funding for pollution control programs.
Individuals can also help to control pollution. They can reduce their own pollution by driving less, using less energy, and recycling more. They can also support businesses and organizations that are working to reduce pollution.
Environment and human health
The environment is the natural world that surrounds us. It includes the air we breathe, the water we drink, the food we eat, and the land we live on. The environment is essential for human health. It provides us with the air we need to breathe, the water we need to drink, and the food we need to eat. The environment also provides us with places to live, work, and play.
Human activities can damage the environment. Pollution, Climate change, and deforestation are all examples of human activities that damage the environment. These activities can have a negative impact on human health.
Pollution can cause respiratory problems, heart disease, cancer, and other health problems. Climate Change can lead to extreme weather events, such as heat waves, floods, and droughts. These events can cause injuries, deaths, and property damage. Deforestation can lead to soil erosion, flooding, and loss of Biodiversity-2/”>Biodiversity.
It is important to protect the environment to protect human health. We can do this by reducing pollution, reducing our carbon footprint, and conserving Natural Resources.
Effects of pollutants on animals and plants
Pollutants can have a variety of effects on animals and plants. Some pollutants can kill animals and plants outright, while others can cause long-term health problems. Pollutants can also disrupt ecosystems, making it difficult for animals and plants to survive.
Air pollution is one of the most common types of pollution that affects animals and plants. Air pollution can cause respiratory problems, heart disease, and cancer in animals. It can also damage plants, making them more susceptible to disease and pests.
Water pollution is another major threat to animals and plants. Water pollution can cause reproductive problems, birth defects, and cancer in animals. It can also kill fish and other aquatic life.
Land pollution can also harm animals and plants. Land pollution can contaminate soil and water, making it difficult for plants to grow. It can also poison animals that eat contaminated plants or soil.
Noise pollution can also have a negative impact on animals and plants. Noise pollution can cause stress, anxiety, and hearing loss in animals. It can also disrupt breeding and Migration patterns.
Radiation pollution can cause cancer, genetic mutations, and other health problems in animals and plants. It can also damage ecosystems, making it difficult for animals and plants to survive.
Urbanisation and industrial development:
Urbanisation is the process of people moving from rural areas to cities. Industrial development is the process of building factories and other industrial facilities. Both urbanisation and industrial development can have a negative impact on the environment.
Urbanisation can lead to air pollution, water pollution, and land pollution. Industrial development can also lead to air pollution, water pollution, and land pollution. In addition, industrial development can lead to deforestation and the loss of biodiversity.
Sustainable Development is a type of development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development can help to reduce the negative impact of urbanisation and industrial development on the environment.
Sustainable development can be achieved by using RENEWABLE ENERGY sources, reducing waste, and conserving natural resources. Sustainable development can also be achieved by planning and managing urban areas in a way that minimizes environmental impact.
