Monitoring Toxics with Passive Sampling Devices

This effort explores the use of passive sampling technology to characterize levels of organic contaminants in fresh water and determine changes over time. Semi-permeable membrane devices (SPMDs) passively sample surrounding water for about 28 days. The SPMDs contain a synthetic fat which mimics the fat found in fish. SPMD samples are analyzed for PBTs such as chlorinated pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs).
