| distribution of butyltin and derivatives in oyster shells and trapped sediments of two estuaries in cantabria (northern spain). | distribution of butyltin compounds (bts) and derivatives (monobutyltin, mbt; dibutyltin, dbt and tributyltin, tbt) was analysed in crassostrea gigas oyster shells and the sediments trapped in the shell chambers, from two different estuaries in cantabria (northern spain), with very different environmental conditions, where previous data have not been reported. inorganic tin analysis in oyster shells was performed in order to study the degradation of bts. shell thickening and losses in biological ... | 2007 | 17166551 |
