Chlorinated aromatic compounds are organic chemicals that contain chlorine atoms attached to an aromatic ring, which is a stable structure made of carbon atoms. These compounds are often used in various industrial applications, including the production of pesticides, dyes, and pharmaceuticals. Their unique chemical properties make them useful, but they can also pose environmental and health risks. Due to their stability, chlorinated aromatic compounds can persist in the environment and accumulate in living organisms. Some well-known examples include polychlorinated biphenyls (PCBs) and dioxins, which are associated with adverse health effects. Regulatory measures are in place to manage their use and reduce exposure.
