Primary determination of butyltins in sediments of Pearl River delta

Butyltins in sediments of Pearl River Delta were extracted with a modified solvent system, and determined by GC-AED. It was shown that there is wide butyltins pollution in Pearl River Delta. The concentration of tributyltins in sediments ranges from 20 to 380 ng /g (dry weight). The regional TBT con...

Zusammenfassung:Butyltins in sediments of Pearl River Delta were extracted with a modified solvent system, and determined by GC-AED. It was shown that there is wide butyltins pollution in Pearl River Delta. The concentration of tributyltins in sediments ranges from 20 to 380 ng /g (dry weight). The regional TBT contamination level in surface sediments is assumed to be within n x 10 ng/g (dry weight, n
