The results show that there are protozoa(main infusorian)and mini-metazoa(rotifer and daphnia)communities in PFU.

结果表明：PFU中的原生动物主要是纤毛虫，微型后生动物主要是轮虫和水蚤。

PFU can be used as a sampling method for detection of organic chloride pollutants in natural water body and concentration variety of organic chloride pollutants in continuous water body.

有机氯污染物检测结果与PFU微型生物参数变化趋势相吻合。 PFU法可用于天然水体中有机氯污染物的筛选，以及连续水体中有机氯污染物浓度变化的监测。
