What are polychlorinated biphenyls (PCBs) known for?

Polychlorinated biphenyls (PCBs) are known for their detrimental health effects, particularly in relation to cancer and developmental issues in children. They are classified as environmental pollutants and have been linked to a range of adverse biological impacts. Research indicates that exposure to PCBs can increase the risk of various cancers, as well as cause serious developmental problems in children, including cognitive deficits and behavioral issues.

This link to carcinogenicity and negative impacts on children's health is well-documented in scientific literature. Understanding the harmful effects of PCBs has led to stricter regulations and a phased ban on their production and use in many countries. This highlights the significant concerns surrounding the usage of PCBs in the environment and its associated health risks, reinforcing the appropriateness of the chosen answer.
