potential pollutant

Sediment quality in waters not only affect the benthic organism, but also has close relation with the water quality due to the frequent pollutant interchanges between the sediment and overlaying water. The polluted sediment often becomes the potential source to pollute waters.

水体沉积泥沙质量不仅对底栖生物具有影响，而且由于泥沙与上覆水体相互间频繁的交换作用，泥沙质量与水体水质也有着密切的关系，污染的泥沙往往会成为水域的潜在污染源。

The study does not measure the potential impact of pollutant-driven sex change for frog species, but the implications, said Berg, are disquieting.

塞里西亚说，这项研究没有对因污染导致青蛙物种发生性变的潜在影响进行评估，但它却暗示我们前景令人担忧。
