Polychlorinated Biphenyls(PCBs) are the semi volatile organic pollutants which are liphophilic, hydrophobic and carcinogenic in nature. PCBs are resistant to degradation, due to which, they are persistent in environment and migrate far distances from the origin of their use. Volatilization from water bodies to the atmosphere is a significant environmental pathway for migration of hydrophobic pollutants like PCBs.Knowledge of Henry's law constant (H) is essential in calculating the rate and direction of transfer. Henry's law constant (H) is the ratio of concentration of a compound in air to that of water at equilibrium. A modified equilibration technique was used to determine the Henry's Constants for seven Polychlorinated Biphenyls (PCBs) which are found in the environment. This method involves the combination of Equilibrium Partitioning in Closed systems (EPICS) and Solid Phase Micro Extraction (SPME) sampling technique, in which an aqueous diluted stock solution is prepared and attained equilibrium dynamically in a closed system. Further sampling of headspace and water in the experimental set up is done consequently. SPME is an integrated process in which sampling, extraction and pre concentration is done simultaneously. Analysis was done using Gas Chromatography coupled with Electron Capture Detector. By employing mathematical model, Henry's Constants ranging from 0.0001 to 0.02(non-dimensional) for different individual congeners were observed.
