Oyster samples from 53 Gulf of Mexico coastal sites were collected and analyzed for butyltins during 1989, 1990, and 1991. The geometric-mean tributylin concentrations were 85, 30, and 43 ng Sn/g for 1989, 1990, and 1991, respectively. The tributyltin concentrations are best represented by a log-normal distribution. A decline in the butyltin concentrations at sites with relatively low butyltin concentrations for 1989 compared with 1990 and 1991 was observed, and, at relatively high butyltin concentrations (> 400 ng Sn/g), there was hardly any difference between 1989 and 1991, but lower concentrations were present in 1990. Continued monitoring is needed in order to determine if butyltin contamination of the coastal marine environment is decreasing in response to use limitations.
1989年、1990年和1991年期间，采集了来自墨西哥湾53个沿海地点的牡蛎样本，并对其中的丁基锡进行了分析。1989年、1990年和1991年三丁基锡的几何平均浓度分别为85、30和43纳克锡/克。三丁基锡浓度最适合用对数正态分布来表示。观察到，与1990年和1991年相比，1989年丁基锡浓度相对较低的地点，其丁基锡浓度有所下降；而在丁基锡浓度相对较高（>400纳克锡/克）的地点，1989年和1991年之间几乎没有差异，但1990年的浓度较低。为了确定沿海海洋环境中的丁基锡污染是否因使用限制而减少，需要持续进行监测。
