Polychlorinated Biphenyls (PCBs) are known to cause which of the following health issues?

Polychlorinated Biphenyls (PCBs) are associated with a variety of health issues, particularly skin changes and immune deficiencies. These chemicals can accumulate in the body over time and disrupt normal biological functions. The skin changes can manifest as chloracne, a condition characterized by cysts and lesions, which is specifically linked to exposure to PCBs. Furthermore, PCBs have been shown to adversely affect the immune system, potentially leading to increased susceptibility to infections and other diseases by impairing immune response.

While other health issues are certainly serious, such as respiratory problems or neurological defects, they are not the primary concerns associated with PCB exposure. Understanding the specific health risks associated with PCBs is crucial for water operators to mitigate exposure and protect public health, as these chemicals can enter water sources and affect both ecosystems and human health.
