Abstract

Short-chain chlorinated paraffins (SCCPs) are polychlorinated-[C10 to C13]-n-alkanes which are used as additives in metal working fluids and flame retarding applications. They have physical properties similar to many persistent organic pollutants (POPs). In this study levels of SCCPs were measured in effluents, sediments, water, air, and fish from Lake Ontario and in beluga whale (Delphinapterus leucas) blubber from the St. Lawrence River estuary and the Canadian arctic. SCCPs were detected in all samples but generally at levels much lower than PCBs. There was also evidence for biotransformation of SCCPs. The results suggest SCCPs are not as persistent or bioaccumulative as many POPs.
