"The antifouling agent tributyltin (TBT) is the most toxic chemical that has ever been deliberately introduced to aquatic environments. It is a classic endocrine disrupting substance, exhibiting effects in marine snails at concentrations as low as 0.5 mg Sn/L, and sterilizing female snails at concentrations at about 3-5 ng Sn/L.... This work illustrates qualitatively the persistence of TBT in a sediment core from Toronto Harbour. Results of this work will be useful to PMRA in its regulation of TBT. The results of this work also provide some support to the conclusion that TBT is a Track 1 substance under Canada’s Toxic Substances Management Policy"--Management Perspective.
