Detailed explanation-1: -Pollutant = harmful material that can enter the biosphere through the land, air or water.

Detailed explanation-2: -Atmospheric Nitrogen and Sulfur Deposition and Impacts on Ecosystems. Atmospheric deposition of nitrogen and sulfur resulting from air pollution is a major stressor to natural ecosystems, often leading to acidification and eutrophication of both terrestrial and aquatic ecosystems.

Detailed explanation-3: -These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.

Detailed explanation-4: -Nitrogen Dioxide NO2 is the most harmful of these compounds and is generated from the combustion of fuel engines and industry. It can damage the human heart and lungs and it reduces atmospheric visibility at high concentrations.

Detailed explanation-5: -Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides-chemical poisons used to kill weeds and insects-seep into waterways and harm wildlife.
