Chemicals and Pesticides Found in the Great Lakes

Pesticides affect fish hormones. This can cause endocrine disruption. It may affect fish species harmful to the water environment. The Indonesian Citarum River is probably the most contaminated river in the river. It is covered with debris covering its surface. The river textile factory lives in a river that releases harmful chemicals to the river. Hazardous chemical substances contained in rivers include lead, mercury, arsenic, cadmium, chromium, pesticides.

Pesticides are a source of pollution that affects land and water, especially everywhere. The problem is getting bigger and bigger. According to the US Geological Survey of 1990, pesticide contamination has been confirmed in most or all lakes, streams, lakes, municipalities and farmlands. Many other countries are also seriously affected in the world. Because rainwater cleaning chemicals are close to water sources, most chemical products are pesticides because they have been used to promote the growth of agricultural land, gardening land and home garden, but the main sources of exposure to pesticides are mainly people.

Agricultural practices are known to contribute to non-point source water pollutants including sediments, salt, fertilizer (nitrates and phosphorus), pesticides and fertilizers. Pesticides from various types of chemicals are detected in groundwater and are commonly found in underground water under agricultural areas; they are widespread in the surface waters of the country. Eutrophication and "dead zones" caused by nutrient runoff have affected many rivers, lakes and oceans. Water quality decline affects agricultural production, drinking water supply and fishery production

Pesticides are widely used chemicals in agriculture to improve yield and quality by suppressing pests and pest related diseases. Extensive use of pesticides is an important cause of air, water and soil contamination. Insecticides are not only influencing health through abuse and accidents, they are not only leaving permanent hazardous chemicals in the environment but also a very important risk factor in human life. Most pesticides do not specifically target pests, and plants and animals that are not covered are also affected during application. It is estimated that only about 0.1% of the pesticide will reach the target organism and the remaining pesticide contaminates the surrounding environment. Every living thing, human beings, and the environment are at risk of adversely affecting agricultural chemicals, especially for families of agricultural workers and pesticide spreaders who are at the highest risk.
