Pesticide Runoff from Agriculture

Non-point sources are in contrast to point source contamination arising from certain places such as pipes and chimneys. Contamination of a dotted line source occurs from a specific place or object, so it can be easily measured or stopped, but contamination from a point other than the dotted line occurs from the diffusion area, so measurement or stopping is not easy (ExtoxNet) . Agricultural land is an important cause of drinking water pollution mainly due to current and former agricultural practices. There are some habits: excess fertilization, it is a combination of fertilizer and fertilizer.

Water pollution is the pollution of water by chemical substances or other foreign substances harmful to human health, plant or animal health. These pollutants include chemical contaminants from fertilizers and pesticides from agricultural outflow water, sewage and food processing waste, lead, mercury, other heavy metals, industrially discharged chemical waste, and hazardous waste sites included. Approximately 2 billion people around the world will drink contaminated water that could harm your health. 14th report on carcinogens - a science-based public health document approved by the National Standards Committee for Secretary of HHS. The cumulative report now contains 248 lists of substances, substances, mixtures and exposures that are known to reasonably be expected to cause cancer in humans.

Water pollution occurs when chemical substances including chemicals in metals such as agricultural water, sewage, agrichemicals, chemical fertilizers, lead or mercury and harmful foreign substances are brought into the water. According to the US Environmental Protection Agency (EPA), 44% of the estimated mileage, 64% of the lake, 30% of the bay and estuary area are not clean enough for fishing or swimming. The US Environmental Protection Agency also pointed out that the most common pollutants in the United States are bacteria, mercury, phosphorus and nitrogen. These are derived from the most common source of contamination, such as agricultural outflow, air sediment, water flow, stream stream formation in streams.
