〔目的〕了解入境船舶载自境外压舱水的大肠菌群污染情况。〔方法〕无菌采集入境船舶载自境外的压舱水样本,进行大肠菌群培养分离鉴定。〔结果〕2007年8—10月共监测69艘次入境船舶载自境外港口的60万余吨压舱水,检出大肠菌群的阳性船舶11艘次,船舶阳性率为15.94%,压舱水阳性比例为18.39%(110378/600064)。其中大肠菌群数量达第4类海水水质标准的9艘次,共计73790t,船舶阳性率为13.04%(9/69),4类水质压舱水阳性比例为12.30%(73790/600064)。〔结论〕入境船舶载自境外的压舱水大肠菌群污染严重。
[Purpose] To understand the contamination of coliform bacteria contained in the ballast water of the incoming ships. [Method] Aseptic collection of ballast water samples from inbound vessels carried by vessels entering China for colony culture isolation and identification. [Results] From August to October 2007, a total of 69 vessels were monitored for more than 600,000 tons of ballast water carried in ports outside the country. Eleven colony-positive vessels were detected. The positive rate was 15.94% The water-positive ratio was 18.39% (110,378/600064). The number of coliform groups was 9 ships of the 4th class seawater quality standard, totaling 73790t, the positive rate of the ship was 13.04% (9/69), and the positive ratio of the 4 types of water quality ballast water was 12.30% (73,790/600064). [Conclusion] The coliform bacteria contained in the ballast water contained in the incoming vessels were seriously polluted.
