Answers
Answer:
Water can be contaminated by physical pollutants (solid material), biological pollutants (such as bacteria that cause waterborne diseases), and many different chemical pollutants. Air pollution can be caused by gases or solid particulates. Soil pollution is linked to groundwater pollution.
The soil is an integral part of the natural environment. Although much concern over the years has been on air and water pollution, prevention and control of soil pollution are as important as air and water pollution control. In fact, soil can impact on air and water quality as it is home to a wide range of organisms and plays a bigger role in the distribution of plant species.
Furthermore, the soil acts as a source and a store for gases. It also influences the flow of chemical substances and water between the earth and the atmosphere. Unfortunately, over the years, human activities like the use of pesticides, fungicides, and herbicides have had an adverse effect on soil quality. In addition to agricultural pollution, industrial waste and urban activities also cause soil pollution.
