[Occurrence and distribution of organotin compounds in Thais clavigera from Xiamen coast].
Occurrence and distribution of 6 organotin compounds including butyltin and phenyltin species were detected in Thais clavigera which were collected from 9 coastal areas sites around Xiamen Coast, by pentylized derivatization, GC-FPD. Results indicated that all Thais clavigera samples were contaminated with organotin compounds. The concentrations in Thais clavigera soft bodies varied from 0.3 to 70.6 ng x g(-1) with a mean value of 28.8 ng x g(-1) for butyltin compounds, and from nd to 18.8 ng x g(-1) with a mean value of 7.9 ng x g(-1) for phenyltin compounds, respectively. MBT and TPhT were high levels in butyltin compounds and phentyltin compounds, respectively. In addition, butyltin compounds were the dominant contaminates in all samples with high percentage from 74.3% to 96.8%. There was a significant correlation between TBT and TPhT (R2=0.7109, p<0.01). This result showed that both TBT and TPhT came from antifouling paints for ships or for mariculture nets. Compared with those data reported from the other regions around southeast coast of China, present study reveals that contaminated level of organotin compounds in Thais clavigera are relatively lower in Xiamen Coast. But it is higher than those in 2002.
