PCB 153

Description:
PCB 153, or 2,2',4,4',5,5'-hexachlorobiphenyl, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals known for their environmental persistence and potential toxicity. This compound features six chlorine atoms attached to a biphenyl structure, contributing to its stability and resistance to degradation. PCB 153 is characterized by its hydrophobic nature, low volatility, and lipophilicity, which facilitate its accumulation in biological systems and the environment. It is primarily used in industrial applications, including electrical equipment, heat transfer fluids, and as a dielectric fluid. Due to its environmental persistence, PCB 153 has been detected in various ecosystems, leading to concerns regarding its bioaccumulation and potential adverse health effects in humans and wildlife, including endocrine disruption and carcinogenicity. Regulatory measures have been implemented globally to limit the production and use of PCBs, including PCB 153, due to their environmental and health risks.
