Love River passes through the harbor of Kaohsiung and connects with the sea bring hidden ecological crises. Because there are persistent shipping from the whole world, several shipyards and fishing ports in the harbor of Kaohsiung, the pollution of organotin is very serious in the harbor area. It’s possible that Love River may be polluted by the seawater from the harbor of Kaohsiung for the long intertidal zone and the estuary, in the harbor of Kaohsiung. Upstream sections may be also polluted by organotin compounds from domestic, industrial and agricultural wastewater. This study is not only collecting the surface and bottom riverwater during winter and summer, but also sampling the sediments in Love River. These samples are derivated with NaBEt4 and analyzed the concentration of organotin by gas chromatograph with a flame photometric detector. The results reveal that concentrations of MBT are 8.2-25.0 ng/L as tin, DBT are 3.3-17.1 ng/L as tin, TBT are 4.3-9.1 ng/L as tin in the riverwater. The concentrations of MBT are 12.5-69.2 ng/g as tin, DBT are 7.1-31.2 ng/g as tin, TBT are 15.8-22.6 ng/g as tin in the surface sediments. The pollution of organotin decrease from the harbor of Kaohsiung to the water gate in the downstream. A peak of pollution is found near the Yu-Cheng bridge in the upstream. The concentrations of the vertical distribution of sediments, MBT are as high as 61.2-273.2 ng/g as tin, DBT are 22.8-256.2 ng/g as tin, TBT are 8.6-168.4 ng/g as tin, it indicates that Love River was polluted extremely seriously by organotin compounds in the past. However, phenyltin compounds were not detected in these samples. As compared with previous reports, today the pollution of organotin compounds has been greatly reduced in Lover River. But it remains to be cared in order to reduce the potential ecological crises which are brought by the pollution. Wei-Hsien Wang 王維賢 2009 學位論文 ; thesis 105 zh-TW |

Love River passes through the harbor of Kaohsiung and connects with the sea bring hidden ecological crises. Because there are persistent shipping from the whole world, several shipyards and fishing ports in the harbor of Kaohsiung, the pollution of organotin is very serious in the harbor area. It’s possible that Love River may be polluted by the seawater from the harbor of Kaohsiung for the long intertidal zone and the estuary, in the harbor of Kaohsiung. Upstream sections may be also polluted by organotin compounds from domestic, industrial and agricultural wastewater.
This study is not only collecting the surface and bottom riverwater during winter and summer, but also sampling the sediments in Love River. These samples are derivated with NaBEt4 and analyzed the concentration of organotin by gas chromatograph with a flame photometric detector.
The results reveal that concentrations of MBT are 8.2-25.0 ng/L as tin, DBT are 3.3-17.1 ng/L as tin, TBT are 4.3-9.1 ng/L as tin in the riverwater.

However, phenyltin compounds were not detected in these samples.
As compared with previous reports, today the pollution of organotin compounds has been greatly reduced in Lover River. But it remains to be cared in order to reduce the potential ecological crises which are brought by the pollution.
