Pollution is defined as the introduction of contaminants into the natural environment that cause adverse effects. Pollution can take various forms including chemicals, noise, heat and light. Common types of pollution include air pollution from vehicle and industrial emissions, noise pollution from transportation and industry, soil contamination from chemical spills and leaks, and water pollution from wastewater and plastic discharge. Multiple contaminants like carbon monoxide, sulfur dioxide, heavy metals and chlorinated hydrocarbons pollute the air, soil and water.

18. Water Pollution
Environmental
Pollution
Water pollution is caused by the discharge of wastewater from commercial and
industrial waste (intentionally or through spills) into surface waters.

19. Water Pollution
Environmental
Pollution
Water pollution is caused by the discharge of wastewater from commercial and
industrial waste (intentionally or through spills) into surface waters.

20. Water Pollution
Environmental
Pollution
Water pollution is also caused by discharges of untreated domestic sewage, and
chemical contaminants, such as chlorine, from treated sewage into surface waters.

21. Water Pollution
Environmental
Pollution
Water pollution is caused by release of waste and contaminants into surface runoff
flowing to surface waters (including urban runoff and agricultural runoff, which may
contain chemical fertilizers and pesticides).

22. Water Pollution
Environmental
Pollution
Water pollution is caused by waste disposal and leaching into groundwater;
eutrophication and littering.

24. Light Pollution
Environmental
Pollution
Light pollution refers to light trespass, over-illumination and
astronomical interference.

25. Littering
Environmental
Pollution
Littering is the criminal throwing of inappropriate man-made objects, unremoved,
onto public and private properties.

26. Radioactive
Contamination
Environmental
Pollution
Radioactive contamination refers to pollution resulting from 20th century activities in
atomic physics, such as nuclear power generation and nuclear weapons research,
manufacture and deployment.

27. Visual Pollution
Environmental
Pollution
Visual pollution refers to the presence of overhead power lines, motorway billboards,
scarred landforms (as from strip mining), open storage of trash, municipal solid waste
or space debris.

28. Plastic Pollution
Environmental
Pollution
Plastic pollution involves the accumulation of plastic products in the environment
that adversely affects wildlife, wildlife habitat, or humans.

29. Thermal Pollution
Environmental
Pollution
Thermal pollution, is a temperature change in natural water bodies caused by human
influence, such as use of water as coolant in a power plant.

helping out my son with his school assignments and project
work. I am happy to share this with other students and their
parents. Hope you find this informative and useful. Thank you.
