Detergents containing phosphates are known to be water pollutants because phosphates are a primary nutrient of algae. When algae grow in excess, it can choke a lake or river and draw off needed oxygen from aquatic life. This is called eutrophication

Nitrates are also harmful to the environment. Calcium, sodium, potassium, and ammonium nitrates are used in fertilisers to provide a source of nitrogen for plant growth. If these nitrates get into the water flow then they can, like phosphates, have damaging effects on the life that live there.

Factory chimneys emit Sulphur Dioxide, which has to be monitored. Inside the chimneys are several filters that sift out the solids in the emissions. Sulphur dioxide emitted into the atmosphere by industrial processes is ultimately converted into dilute sulphuric acid, returning to Earth as acid rain. For this reason, sulphur dioxide is a major cause of air pollution. Acid rain is rain with a greatly lowered pH. Oxides of nitrogen are also emitted from car exhausts that also add to the formation of acid rain. The acid rain in turn comes down and erodes buildings and other things.
