对2000年夏季韩国沿海水域原生动物群落结构和功能参数作为水质指标进行了评价。采用一种改良的聚氨酯泡沫单元（PFU）方法，命名为瓶装PFU （BPFU）系统，进行生物评价。这两个参数都表明，在近海地区，使用BPFU系统进行生物监测比传统的PFU方法更有效。在3个主要站点，BPFU系统采集的物种数量总体上随着污染强度的增加而减少，但多于PFU方法（配对t检验，t=4.83, p<0.0001）。Margalef多样性指数与水分条件吻合较好。BPFU系统计算的多样性指数值也显著高于PFU方法（配对t检验，t=5.37, p<0.0001）。此外，Seq、G和T90%的功能参数与污染状况相关，可以清楚地区分不同类型的水质。
Structural and functional parameters of protozoan communities were assessed as indicators of water quality in Korean coastal waters in the summer of 2000. A modified polyurethane foam unit (PFU) method, named the bottled PFU (BPFU) system, was used in order to carry out the bioassessment. Both parameters suggested that biomonitoring using the BPFU system was more effective than the conventional PFU method in offshore areas. The species number collected by the BPFU system generally decreased as pollution intensity increased at three main stations and was greater than that collected using the PFU method (paired t-test, t=4.83, p<0.0001). The Margalef diversity index coincided well with the water conditions. The diversity index values calculated from the BPFU system were also significantly higher than those from the PFU method (paired t-test, t=5.37, p<0.0001). Furthermore, the functional parameters, i.e. Seq,G and T90%, correlated with the pollution status and could thus clearly discriminate the different classes of water quality.
