Surface water, sediment, and fish from Biscayne Bay, coastal wetlands adjacent to the Bay, and canals discharging into the Bay were sampled for determination of baseline contamination in Biscayne National Park. While the number of contaminants detected in canal waters was greater during the wet season than the dry season, no seasonal difference was evident for Biscayne Bay or coastal wetland waters. Estrogen equivalency (as 17β-estradiol equivalents), as predicted by the Yeast Estrogen Screen, for extracts of passive water samplers deployed in canals and wetlands was elevated during the wet relative to the dry season. Generally, contamination in water, sediments, and fish was greater in the canals than in Biscayne Bay and the wetlands. Guideline levels for sediment contaminant were exceeded most frequently in canals relative to the coastal wetlands and the Bay. Further investigation is necessary to better understand the impact of contaminants in Biscayne National Park.
从比斯坎湾的地表水、沉积物和鱼类，到毗邻该湾的沿海湿地以及排入该湾的运河，均采集了样本，以确定比斯坎国家公园的基线污染情况。虽然在雨季，运河水中检测到的污染物数量比旱季多，但在比斯坎湾或沿海湿地水中，并没有明显的季节性差异。通过酵母雌激素筛选预测，在运河和湿地中部署的被动水样采集器提取物中的雌激素当量（以 17β-雌二醇当量计）在雨季相对旱季升高。一般来说，水、沉积物和鱼类中的污染在运河中比在比斯坎湾和湿地中更为严重。与沿海湿地和海湾相比，运河中的沉积物污染物超标情况最常见。需要进一步调查，以更好地了解污染物对比斯坎国家公园的影响。
