Occurrence of organotin compounds in the Canadian environment five years after the regulation of antifouling uses of tributyltin / Y.K. Chau ... [et al.].: En13-5/96-161E-PDF
"A survey was conducted of water and sediment from across Canada in 1993.-1994 to assess the effectiveness of the 1989 regulation of antifouling uses, of tributyltin (TBT) under the Canadian Pest Control Products Act. The survey was also designed to assess concentrations of 13 other organotin species in water and sediment, and in sewage treatment plant influents, effluents and sludges. The main conclusion is that the 1989 regulation has only been partially effective. It has had some effect in the reduction of TBT concentrations in fresh water, but not in sea water. It has had less effect in the reduction of TBT concentrations in sediment, probably because of the longer persistence of TBT in sediment than in water. In many locations the TBT concentration was high enough to cause acute and chronic toxicity to aquatic and benthic organisms. In some areas there may be potential for recycling TBT from contaminated sediments back into the water column. In addition, it appears that large harbours that handle ships legally painted with TBT-containing antifouling paints will continue to experience ecotoxicologically significant TBT contamination"--Abstract.
