자란만․사량도 패류생산해역의 위생학적 안전성 평가 = Evaluation of the Bacteriological Safety for the Shellfish Growing Area in Jaranman․Saryangdo Area, Korea

다국어 초록 (Multilingual Abstract)

Bacteriological examination of a 12,700 ha area within Jaranman․Saryangdo area, located in Jaran bay and Saryangdo island, was conducted with 35 fixed (designated areas and adjacent areas) seawater sampling stations between January 2006 and December 2008. According to results, the geometric mean range and the estimated 90th percentile range of fecal coliform counts in sea water samples collected in the designated area were <1.8-2.4 and <1.8-8.6 MPN/100mL, respectively. The estimated 90th percentile range of fecal coliform counts in sea water samples collected from 6 sampling stations in the adjacent areas were 6.1-34.6 MPN/100mL. Based on these results, bacteriological water quality of the designated areas in the Jaranman․Saryangdo area meet the NSSP (National Shellfish Sanitation Program) guidelines for approved area.
The bacteriological sea water quality in Jaranman․Saryangdo area has been shown to be favorable at all investigated sampling stations except for July and August which coincided with heavy rainfall. In fact, the bacteriological water quality was not affected if rainfall was less than 30mm rainfall. However, the degree of bacteriological contamination increased rapidly and the water quality exceeded approved NSSP guidelines set for rainfall above 60mm.
