Chlorinated aromatics are organic compounds that contain chlorine atoms attached to an aromatic ring, which is a stable structure made of carbon atoms arranged in a specific way. These compounds are often used in various industrial applications, including the production of pesticides, solvents, and dyes. Due to their chemical stability, chlorinated aromatics can persist in the environment, leading to potential ecological and health concerns. Some well-known examples include polychlorinated biphenyls (PCBs) and dichlorodiphenyltrichloroethane (DDT), which have been studied for their toxic effects on wildlife and humans.
