本研究係採集高屏地區共八個大小不同港口（高雄港、東港、大鵬灣、枋寮、海口港、楓港、山海港及後璧湖），共計22個採樣點之表層底質，進行有機錫、有機碳及有機氮的分析。
實驗結果發現，各採樣點的有機錫含量與粒徑大小呈現相關性。三丁基錫濃度介於0.041~4.843 ppm（as Sn），二丁基錫濃度在0.001~4.626 ppm（as Sn）之間，而單丁基錫的濃度在0.001~4.908 ppm（as Sn）間。在苯基錫化合物部分，三苯基錫濃度介於0~0.298 ppm（as Sn），二苯基錫濃度在0~0.216 ppm（as Sn）之間，單苯基錫介於0~0.143（as Sn） ppm。總合的有機錫含量在高雄港中的前鎮漁港偵測到最高的丁基錫含量。最高的苯基錫濃度，出現在高雄港中的愛河河口採樣點。有機質的部分，最大比例的有機碳、氮均表現在高雄港的愛河河口採樣點，分別為3.75％及0.80％。而各採樣地區的有機碳、氮值，呈現0.757的正相關性。而表層底質的有機錫化合物與有機質一樣表現了正相關性。
雖然本研究之各港口沉積物中平均TBT含量和國外文獻相比並非最高的，但高雄港與東港漁港的TBT含量已超過對二枚貝及端角類之10-dLC50（分別為2.6 mg/kg及2.1 mg/kg），因此其沉積物中有機錫之污染算是相當嚴重。其餘的港口也有高達0.24 ppm以上的含量，確實有必要加以監測。TPT含量在ND-0.35 ppm 間，最高值出現在高雄港（0.35 ppm），在1 ppm內。與國內外文獻比較結果，並無特殊的高含量顯示。
在本研究中，有機錫化合物的分佈是高雄港地區為最高，丁基錫化合物與船隻數量呈現高度相關性。船隻數量及人為活動量是高雄港與其他港口最大的差異，高雄港幅地廣闊、船隻數量多且人為活動量龐大，南邊的港口面積及港口船隻數量相對減小，這與有機錫化合物的分佈呈現了一致性。

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.
