Description:
The partitioning of polychlorinated biphenyls (PCBS) between particulate and dissolved phases of seawater was examined along a concentration gradient in New Bedford Harbor, MA. egression analysis was used to examine the relationship between the log of the partition coefficients (Kp) and the log of the octanol/water partition coefficients (Kow) for six PCB congeners at four stations. easonal trend (i.e., slimmer-winter) in partitioning was observed. og Kp was inversely correlated with temperature and to a lesser extent with total suspended solids (TSS) at each station. ultiple regression analysis indicated that approximately 70% of the variability in log Kp along the PCB concentration gradient was accounted for by temperature, log Kp and TSS. emperature and log K. were equally important in defining changes in log Kp, with TSS contributing the least predictive ability.
