POLLUTION and its types IN THE COMMUNITY.pptx

Pollution is the introduction of contaminants into the natural environment that cause adverse change.[1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities, such as manufacturing, extractive industries, poor waste management, transportation or agriculture. Pollution is often classed as point source (coming from a highly concentrated specific site, such as a factory, mine, construction site), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff).

Many sources of pollution were unregulated parts of industrialization during the 19th and 20th centuries until the emergence of environmental regulation and pollution policy in the later half of the 20th century. Sites where historically polluting industries released persistent pollutants may have legacy pollution long after the source of the pollution is stopped. Major forms of pollution include air pollution, water pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, light pollution, and visual pollution.

Pollution has widespread consequences on human and environmental health, having systematic impact on social and economic systems. In 2019, pollution killed approximately nine million people worldwide (about one in six deaths that year); about three-quarters of these deaths were caused by air pollution.[2][3][4][5][6] A 2022 literature review found that levels of anthropogenic chemical pollution have exceeded planetary boundaries and now threaten entire ecosystems around the world.[7][8] Pollutants frequently have outsized impacts on vulnerable populations, such as children and the elderly, and marginalized communities, because polluting industries and toxic waste sites tend to be collocated with populations with less economic and political power.[9] This outsized impact is a core reason for the formation of the environmental justice movement,[10][11] and continues to be a core element of environmental conflicts, particularly in the Global South.

2. POLLUTION Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural. They can also be created by human activity such as trash or runoff produced by factories. Pollution can take place/ form of chemical substances such as noise, heat or light at a rate faster than it can be dispersed , recycles or stored in some harmful forms .

3. CAUSES Industrial Emission Burning of Fossil Fuels Wildfires Open Burning of Garbage Waste Transportation Agricultural Activities

4. WATER POLLUTION Water pollution is defined as the presence of toxic chemicals and biological agents that exceeds and may pose a threat to human health and the environment. The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates,  plastics.

5. CAUSES Oil Pollution Agriculture Radio- Active Waste Discharge Improper Sewage Disposal Rapid urban Development

6. LAND POLLUTION Land Pollution has emerged to become one of the serious problem that are collectively battle. Land pollution means degradation or destruction of earth’s surface and soil, directly or indirectly as result of human activities. The increasing number of barren lands and decreasing number of forest cover are at an alarming rate.

7. CAUSES Mining Activities Nuclear Waste Deforestation Construction Activities Over- Crowed Landfills Industrialization

8. AIR POLLUTION Air Pollution is the release of pollutants such as gases, particles, biological molecules into the air that is harmful to human health and the environment. There is certain percentage of gases present in the atmosphere. An increase or decrease in the composition of these gases is harmful to survival.

9. CAUSES Natural Events Exhaust from Industries and Factories. Coal Power Plant Transportation Domestic Resources Smoking

10. NOISE POLLUTION Unwanted , disturbing, and distractive levels of sound that can cause discomfort to humans and animals is called noise pollution. It can also affect wildlife by interfering with their communication, migration patterns, and feeding habits. It can also have ecological effects, such as the disruption of animal behavior, communication, and migration patterns.

11. CAUSES Vehicles Social events Construction Natural Disasters Increased Industrialization

12. MEASURES Commute smart by walking or riding to work or the shops instead of driving. Motor vehicle emissions remain the most significant source of most common air pollutants. Save energy, by turning off the television and make sure you flick the light switch when you leave the room. Not only will you save money on your electricity bill, you will be reducing emissions from coal-fired electricity plants .

13. MEASURES Use environmentally friendly cleaning products . Non-conventional sources of energy. Harvesting of rain-water to meet water requirements of industries and other domestic purposes.
