Pesticides have been found in aquatic ecosystems such as groundwater, lakes, rivers and oceans through clogged storm drains, improper disposal, unplanned discharges and accidental spills. Pesticide exposure results in a variety of abnormalities in the human body, including mutagenic or genotoxic impacts. Pesticide-exposed organisms exhibit a wide range of developmental abnormalities, including genital deformities. Herbicides have a direct negative impact on the population size of primary producer. Pesticides accumulate in rivers and fresh water because of the high concentration of pesticides in the agricultural environment. Toxicants produced by humans have been identified as a severe threat to freshwater ecosystems. Pesticide use has led to the drastic decline of the populations of certain fish species. Insecticides, herbicides and fungicides have all been associated with a decrease in several animal species. Pesticides accumulate in the bodies of fish and have an impact on human health as a result of biological cycling and bio-magnification. Not only can pesticides affect fish, but they can also affect the food webs that support them. Pesticides enter the human body through a variety of ways, including the food chain, air, soil, water, flora and fauna and the environment. In pesticide applicators, farmers and farm workers in general, abnormalities and illnesses of the skin have been documented
