Chlorinated Aromatic Hydrocarbons (CAHs) are organic compounds that contain both chlorine atoms and aromatic rings in their structure. These compounds are often used in industrial applications, such as solvents, pesticides, and plastic production. Due to their stable chemical nature, CAHs can persist in the environment, leading to potential ecological and health concerns. The presence of CAHs in soil and water can result from industrial discharges or improper waste disposal. Some well-known examples of CAHs include polychlorinated biphenyls (PCBs) and dioxins. Their toxicity can affect wildlife and humans, making monitoring and regulation important for environmental safety.
