Pollution Control Pollution control is a term used in environmental management It means the control of emissions and effluents into air, water or soil Pollution prevention and waste minimization are more desirable than pollution control Pollution Control Practices : Recycling Reusing Waste minimisation Mitigating Compost
28Polluter Pays Principle Around 300 BC, Kautiliya in his Arthasastra prescribed different levels of financial penalties for causing harm to the environment If anyone intentionally spoils the water of another ... let him not only pay damages, but purify the stream or cistern which contains the water. Plato, Greek Philosopher The 'polluter pays' principle is the commonly accepted practice that those who produce pollution ShOUId bear the costs of managing it to prevent damage to human health or the environment The polluter pays principle underpins environmental policy such as an ecotax, which, if enacted by government, deters and essentially reduces greenhouse gas emissions The Precautionary Principle is a strategy to cope with possible risks where scientific understanding is yet incomplete, such as the risks of nano technology, genetically modified organisms and systemic insecticides.
29Precautionary Principle In simple terms, the PP conveys the common-sense based advice - to err on the side of caution. The principle intends to prevent harm to humans, environment, and eco-system at large. Dioxin is a general term used to describe a group of hundreds of chemicals that are highly persistent in the environment. Dioxin is formed by burning chlorine-based chemical compounds with hydrocarbons The major SOUrces of dioxin in the environment include waste- burning, paper mills that use chlorine bleaching, production of polyvinyl chlorine (PVC) plastics, and chlorinated chemicals like pesticides Dioxin is very toxic and has been measured throughout the globe and its persistence, both in humans and the environment, means that future generations will be exposed to dioxin produced today Harm caused by dioxin to humans and ecosystems is likely to be irreversible, or reversible only over decades
30Central Pollution Control Board The Central Pollution Control Board (CPCB) of India is a statutory organisation under the Ministry of Environment, Forest and Climate Change; Established in 1974 CPCB conducts environmental assessments and research. It is responsible for maintaining national standards under a variety of environmental laws, in consultation with zonal offices, tribal, and local governments It has responsibilities to conduct monitoring of water and air quality, and maintains monitoring data.
different types of pollution
Air pollution is defined as the contamination of air by foreign substances that can interfere with human health and welfare when present in sufficient concentrations. It can cause issues like acid rain, ozone depletion, and smog. Water pollution occurs when pollutants are discharged into bodies of water without treatment, degrading the environment and ecosystems. Soil pollution involves toxic chemicals in soil at levels that pose risks to health and the environment. Noise pollution refers to sounds caused by humans that threaten human or animal health, mainly from vehicles, aircraft, machinery, and other equipment. Thermal pollution changes water temperature which can kill aquatic life adapted to specific ranges. Light pollution artificially alters night environments and can compromise health, disrupt ecosystems, and impact aest

sumon ppt of pollution .dekstop.pdf
This document discusses four main types of pollution: land, air, water, and noise. Land pollution occurs through activities like deforestation, mining, agriculture, and construction, and can change climate patterns, pollute soil, and impact health. Air pollution involves introducing chemicals or particles into the atmosphere from sources such as vehicle emissions, fires, and power plants. Water pollution is any change in water quality from human activities that harms life or makes water unsuitable for use, and stems from dumping, industrial waste, and sewage. Noise pollution refers to unwanted loud sounds that disrupt humans and animals, originating from traffic, aircraft, railroads, buildings, loud speakers, and firecrackers.
pollution.pptx
Air pollution refers to harmful pollutants released into the air. It is responsible for nearly 7 million deaths annually according to the WHO. Most air pollution comes from burning fossil fuels for energy and industrial processes. It contributes to climate change and is exacerbated by it. Transitioning to cleaner energy sources like renewables is key to controlling air pollution.
POLLUTION
Pollution is the introduction of substances into the environment that have harmful or poisonous effects. It has various causes including industrialization, population growth, and improper waste disposal. The main types of pollution are air, water, soil, noise, radioactive, thermal, light, and marine pollution. Each type degrades the environment and harms human health in different ways such as respiratory illness, global warming, and toxic dust. Efforts are needed to control pollution at its source and educate the public on environmental protection.
