What are the Common Sources of Toxic Chemical Contamination?
Toxic chemical contamination originates from a variety of sources, including industrial processes, agricultural activities, and urban runoff. Industrial activities release pollutants such as heavy metals, PCBs, and dioxins into the air, water, and soil. Pesticides and fertilizers used in agriculture can leach into groundwater and surface waters, leading to contamination. Additionally, household products and pharmaceuticals contribute to the presence of toxic chemicals in municipal wastewater.
