本研究係採集屏東地區十八個港口之水樣及表層沉積物，利用氣相層析配合火焰光度偵測器(GC-FPD)進行有機錫化合物含量之分析，以瞭解各港口有機錫污染的情況及汙染來源。
　　各港口有機錫化合物濃度分布以丁基錫化合物為主，水樣中單丁基錫濃度介於3.9~51.6 ng/L as tin，二丁基錫濃度介於ND~15.2 ng/L as tin，三丁基錫濃度介於ND~23.9 ng/L as tin，單苯基錫濃度介於2.1~7.2 ng/L as tin；表層沉積物中單丁基錫濃度介於67.0~332 ng/g as tin，二丁基錫濃度介於17.6~325 ng/g as tin，三丁基錫濃度介於26.0~420 ng/g as tin，單苯基錫濃度為ND~43.7 ng/g as tin。
　　研究結果發現，無論水樣或是沉積物，總有機錫濃度皆以東港、鹽埔、後壁湖三個測站較高，顯示各採樣點的有機錫含量和船隻數量及漁業活動量呈現高度的相關性，且水樣中有機錫化合物之分布與表層沉積物亦呈現一致性，少數港口之水樣及沉積物檢測出苯基錫污染，可能為鄰近聚落所排放的家庭廢水所致。
　　本研究結果與其他國家大型港口相比濃度皆不高，而與國內相同港口相比，有機錫化合物濃度十年來已有明顯下降，由此可知在有關當局的嚴格控管之下有一定成效。

Samples including surface sediments and seawaters were collected from eighteen ports of Pingtung County. The objective of this study were to understand sources of organotin pollution and to monitor the organotin pollution of these fishing ports by analying with gas chromatography-flame photometric detection (GC-FPD).
　The results showed that butyltins were the major components of organotin pollution of the fishing ports investigated. The concentrations of MBT, DBT, TBT and MPT in seawaters varied between 3.9~51.6 ng/L as tin, ND~15.2 ng/L as tin, ND~23.9 ng/L as tin and 2.1~7.2 ng/L as tin. The concentrations of MBT, DBT, TBT and MPT in surface sediments varied between 67~332 ng/g as tin, 17.6~325 ng/g as tin, 26~420 ng/g as tin and ND~43.7 ng/g as tin.
　The contents of organotin compounds were relevant to the number of fishing craft and the frequency of fishery activities. Distribution of organotin compounds between seawaters and surface sediments in these fishing ports were correlational. Phenyltin was detected only in a few ports, probably due to the sewage discharge from the nearby villages.
The concentrations of organotin compounds observed in this study are lower than most of the reported values from foreign ports. In comparison with the previous studies in the same areas, organotin concentrations have dropped significantly. These observations are attributed to the effective control over the utilization of organotin compounds by the authorities.
