Abstract :
Structural and functional parameters of protozoan communities were assessed as indicators of water quality in Korean coastal waters in June-July 2000. A modified PFU (polyurethane foam unit) method, named the 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 = 4.85, p < 0.0001). The Margalef diversity index coincided well with the water conditions. The diversity index values calculated form 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., S/sub eq/ and T/sub 90%/, correlated with the pollution status and could thus clearly discriminate the efficient classes of water quality.
