PCB 105

Description:
PCB 105, also known as 2,3,4,5-tetrachlorobiphenyl, is a member of the polychlorinated biphenyl (PCB) family, which consists of organic compounds with two linked phenyl rings and multiple chlorine atoms attached. Its chemical structure features four chlorine atoms substituted on the biphenyl backbone, which significantly influences its physical and chemical properties. PCB 105 is typically a colorless to light yellow solid or viscous liquid, depending on the temperature and purity. It is known for its hydrophobic nature, low volatility, and stability, which contribute to its persistence in the environment. PCB 105 is classified as a persistent organic pollutant (POP) due to its potential for bioaccumulation and long-term ecological effects. It has been associated with various adverse health effects, including endocrine disruption and potential carcinogenicity. Due to these concerns, the production and use of PCBs, including PCB 105, have been largely banned or restricted in many countries. Proper handling and disposal are essential to mitigate environmental and health risks associated with this compound.
