Organic contaminants are substances that contain carbon atoms and are commonly found in the environment as a result of human activities. These contaminants can include pesticides, industrial chemicals, pharmaceuticals, and personal care products. They can enter the environment through various pathways such as agricultural runoff, sewage discharge, and atmospheric deposition. Organic contaminants can have adverse effects on human health and the environment, including disrupting hormone systems, causing genetic mutations, and accumulating in the food chain. Research in this area focuses on identifying sources of organic contaminants, understanding their fate and transport in the environment, and developing strategies to mitigate their impact.
