Chlorinated hydrocarbons are organic compounds that contain chlorine atoms bonded to carbon and hydrogen. They are commonly used in various industrial applications, including solvents, pesticides, and refrigerants. Due to their chemical stability, these compounds can persist in the environment, leading to potential ecological and health concerns. Many chlorinated hydrocarbons, such as dichlorodiphenyltrichloroethane (DDT) and polychlorinated biphenyls (PCBs), have been linked to adverse effects on wildlife and human health. Some of these substances can accumulate in the food chain, raising concerns about their long-term impact on ecosystems and the safety of food sources.
