ABSTRACT- Persistent, bioaccumulative and toxic (PBT) substances are becoming increasingly regulated globally – US, Canada, Europe – under programs such as HPV, TSCA, CEPA (PBiT) and draft EU REACH. Identifying, understanding the risks associated with and then managing these PBTs is an important aspect of any current and future chemicals risk management plan. Additionally, understanding and managing these substances fits well within fully functional corporate environmental stewardship programs and sustainable development. This presentation describes an approach needed to manage such substances. PBTs can fall into three categories: 1.PBTs, those substances that satisfy the three triggers (NB: some jurisdictions only require satisfying two triggers); 2. vPvB (v=very), those substances that far exceed the typical triggers for P and B; and 3. POPs, those substances considered persistent organic pollutants and are slated for removal (i.e., banned) from commerce under the Stockholm Convention of 22 May 2001. The Convention was ratified in February 2004; it is expected to come into force on 17 May 2004. How can these substances be identified prior to their consideration in new and existing products or identified as being present in current products? Many tools exist such as lists, QSAR, PBT profiler (USEPA), or merely use of the triggers during regulatory and product stewardship reviews. Recently, models (e.g., Mackay fugacity mode) have shown promise to assist in identifying potential PBTs (e.g., PFOS) and their long-range transport. An identification scheme as well as some case studies will be presented.
