Farmers cannot control the agricultural pollution causes as, especially during storms, soil erosion will occur and inside the soil which goes into rivers, lakes and streams, will be harmful pollutants. Agricultural soil pollution is one of the biggest threats to the world’s water supplies, as agriculture accounts for the majority of our fresh water usage. The water farmers use on their land will eventually return to groundwater supplies through evaporation, as part of the hydrological cycle, and as it evaporates, the particles of the harmful pollutants which have been introduced into the soil and onto the crops will result in agricultural air pollution. The quality of air will deteriorate as well as the quality of drinking water.
Symptoms associated with building-related health problems are commonly referred to as sick building syndrome. The American Society of Heating, Refrigerating and Air-Conditioning Engineers describes a building in which more than 20 percent of its occupants report building-related illness as a sick building. Symptoms include, but are not limited to, irritation of eyes, nose, and throat; dryness of mucous membranes and skin; erythema; mental fatigue; headaches; airway infections; coughing; hoarseness; wheezing; nausea; dizziness; and unspecific hypersensitivity. It is difficult to identify specific causes of the problem. The complaints reported by the occupants of "sick buildings" are generally nonspecific in nature and, therefore, it is very hard to establish a causal relationship between symptoms and pollutants present in the building.
