2 PBT criteria for identifying POPs Stockholm Convention Persistence (P) media based half-life (T 1/2 ) Water: T 1/2 > 2 Mo Soil/Sed: T 1/2 > 6 Mo Bioaccumlation (B) BCF/BAF > 5000 Log K ow > 5 Toxicity (T) Long range transport potential (LRTP) T 1/2 (air) > 2 days What should we be looking for?

12 Concluding remarks Physical/chemical properties help aid in identifying potential chemical risks to remote environments Current remote atmospheric data on D4 unreliable Improved passive sampler methodology confirms D4 LRTP potential Distinguishing between local and LRTP signatures
13 Concluding remarks D4 not present in deposition media (sediment and stationary biota) Confirms model predictions No risk of exposure via LRT Does LRT potential alone dictate exposure risk in remote environments? Must see the whole picture
