THE DISTRIBUTION OF ORGANOTIN COMPOUNDS IN SEDIMENTS FROM THE PORTS IN KAOHSIUNG AND PINGTUNG,TAIWAN.

The upper layer sediments were collected from eight ports (22 sampling points) of Kaohsiung and Pingtung in southwest Taiwan. The organotin contents in sediment are all related to the grain size. The concentration of tributyltin (TBT) is between 0.041~4.843 ppm (as Sn) , the concentration of dibutyltin (DBT) is between 0.001~4.626 ppm (as Sn), and the concentration of monobutyltin (MBT) is between 0.001~4.908 ppm (as Sn). The Chien-chen harbor presents the hightest butyltins concentrations, and the TBT contents is much over 10-d LC50 to bivalve (2.6 ppm) and amphipoda (2.1 ppm).
The concentrations of triphenyltin (TPT), diphenyltin (DPT) and monophenyltin (MPT) are between ND~0.298 ppm (as Sn), ND~0.216 ppm (as Sn) and ND~0.143 ppm (as Sn) individually. The highest phenyltin concentrations are shown in the outfall of Love River (the inflow of Love River in Kaohsiung Port). The organic carbon and nitrogen contents show significant the positive correlation (R2=0.757), and the organotin concentrations also show a positive correlation with the contents organic carbon.All the butyltins show a positive correlation with the quantities of boats.
According to this study, the port of Kaohsiung presents the most serious content of butyltins and phenyltins in sediment. All the other ports also present a TBT content higher than 0.24 ppm. Therefore, it is recommended to monitor the organotin contents in the ports of this studying area.
