摘要
目的研究2009年7月-2010年6月一年间,环太湖地区微囊藻毒素-LR同主要污染物监测指标之间的相关性。方法通过对环太湖地区21个监测点的微囊藻毒素-LR、藻类密度、水温,pH,溶解氧,高锰酸盐指数,氨氮,总氮,总磷,氮磷比,叶绿素a,硝酸盐氮,总有机碳进行连续监测,按照GB3838-2002《地表水环境质量标准》Ⅱ类水体限值进行评价,采用SPSS15.0统计软件对微囊藻毒素-LR与主要污染指标进行相关性分析。结果发现最严重的污染指标是总氮,年平均值是II类水限制的5.84倍。结论微囊藻毒素-LR同高锰酸盐指数,藻类密度,总有机碳呈统计学正相关。
Objectives To investigate the correlation between microcystin concentration（MC） and the water pollution indexes of the area around Taihu lake from July 2009 to June 2010. Methods The monitoring of pollution indexes related to microcystin concentration（MC） were conducted from July 2009 to June 2010 on alage concentration density （ACD） , water temperature （WT） , pH, dissolved oxygen （ DO ） , permanganate index （CODMn）, ammonia-nitrogen （NH3-N）, total nitrogen （TN）, total phosphor （TP）, TN/TP, chlorophyll-a （Chla） , nitrate-nitrogen （NO3- N）, total organic carbon （TOC）. The correlation between MC and the water pollution indexes was performed with SPSS 15.0 statistical software, the possible correlations among pollution indexes being tested by bivariate correlations. Results The data showed that the most serious pollution index was TN, the annual mean value was 5.84 times of the limit shown in GB3838 -2002 （level Ⅱ）. Conclusion There was a significant positive correlation between MC and COOMn, ACD and TOC.
