Tributyltin and the decline of the Norfolk Broads - additional analytical work - CB01034
|
Description
The use of tributyltin (TBT) anti-fouling paints are banned in fresh waters but to gauge the effectiveness of this measure it was necessary to establish the extent of the ecological impact of TBT on freshwater habitats. There is a correlation between the decline in molluscs in the late 1970s and the peak use of TBT.
This project follows on from the earlier investigation of the links between boats, boat paints and the decline of Wroxham Broad by establishing a definitive chronology from a core collected in 2000 and relating its TBT inventory to biological remains (plant macrofossils, diatoms, molluscs, ostracods and cladocera).
Publication of the Wroxham Broad research was held up as reviewers have suggested the need for replicate TBT inventory data. This project will therefore analyse TBT in sediment core sub-samples from Barton Broad, Norfolk, a lake which lost its aquatic plants and ecological integrity at the same time as Wroxham Broad in the 1960s-1980s.
