Aroclor 1242, a polychlorinated biphenyl (PCB) mixture, was commonly utilized in various industrial applications such as lubricants, hydraulic fluids, and electrical equipment due to its insulating properties. However, its persistence in the environment and harmful effects on human health led to stringent regulations and restrictions on its use. Despite these measures, Aroclor 1242 residues still endure in soil, water, and organisms, posing ongoing risks to ecosystems and public health. Continued efforts in monitoring, remediation, and strict regulatory enforcement are essential to mitigate its environmental and health impacts effectively.
