Partitioning of 2,4,5,2 prime ,4 prime ,5 prime -hexachlorobiphenyl between seawater and air
- Univ. of California, Santa Barbara (USA)
PCBs are generally characterized by low vapor pressures; they would not usually be considered volatile. However, they are also characterized by low water solubilities. Studies addressing PCB toxicology have usually employed open aquaria. Therefore, the objective of this investigation was to describe the gas-liquid partitioning of a single PCB isomer, 2,4,5,2{prime},4{prime}5{prime}-hexachlorobiphenyl (HCBP), in seawater within glass aquaria commonly used for toxicological testing. Partitioning may reduce desired exposure levels during testing, seriously effecting results. However, it may be utilized to realistically model environmental conditions during testing. Therefore, the measured H{prime} will be compared to others obtained with specialized purging equipment. 2,4,5,2{prime},4{prime},5{prime}-HCBP was chosen for its presence in common PCB mixtures and high chlorine content, thus low water solubility and high bioaccumulation potential.
