Partitioning of persistent hydrophobic contaminants to different storage lipid classes

Lipids generally represent the major matrix contributing to absorptive capacity for hydrophobic organic contaminants in aquatic ecosystems. The aim of present study was determine whether partition a different degree storage lipid classes: wax ester (WE) and triacylglycerol (TAG). This undertaken by studying experimentally partitioning organochlorine compounds between lipids (WE or TAG) silicone rubber phase. Our results indicate that have slightly higher affinity WE than TAG. findings thus corroborate earlier suggestions accumulate greater extent food webs with reliance on WE, such as Arctic. knowledge is interest since it implies possible changes planktonic community species composition, thereby may consequences accumulation apex predators. However, magnitude these remains unknown, there well be other factors importance previously observed Arctic systems. Thus, we here identified aspects regarding need further scrutiny, quantitative estimates suggested difference capacities
