PCB 122

Description:

PCB 122, or polychlorinated biphenyl 122, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals known for their environmental persistence and potential toxicity. PCB 122 is characterized by its biphenyl structure, where two benzene rings are connected by a single bond, with multiple chlorine atoms substituted on the rings. Specifically, PCB 122 has a total of six chlorine atoms attached, which influences its physical and chemical properties, such as its hydrophobicity and resistance to degradation. This compound is typically found as a colorless to light yellow liquid or solid, depending on the temperature and concentration. PCBs, including PCB 122, are known for their electrical insulating properties, making them historically useful in electrical equipment, but they are now largely banned or restricted due to their environmental and health impacts, including potential carcinogenic effects and endocrine disruption. Monitoring and remediation of PCB contamination in the environment remain critical due to their long half-lives and bioaccumulation in the food chain.
