Abstract:
The degree of contamination of Saccharina latissima, the dominant species among macrophyte algae in the sublittoral zones of the Kola Bay and Eastern Murman of the Barents Sea, with organotin compounds (monobutyltin, dibutyltin, tributyltin, tetrabutyltin, triphenyltin, and tricyclohexyltin) has been assessed. The results show a moderate degree of contamination of the studied samples with organotin compounds. The total concentration of six tin compounds was 17-74 ng/g (dry weight) in algal samples. Analysis of the indices of degradation of butyl tin derivatives showed active processes of tributyltin and tetrabutyltin transformation in algae.
