河南省生活饮用水和水源水中草甘膦污染现状的初步调查

Primary Investigation on Glyphosate Contamination in Drinking Water and Source Water in Henan Province

摘要

摘要:
目的分析生活饮用水和水源水中草甘膦的污染现状, 以便对河南省生活饮用水和水源水中草甘膦的污染情况进行初步了解。
方法用Fisher精确检验和非参数Wilcoxon秩和检验对检测结果进行统计学分析。
结果利用Fisher精确检验(P=0.7540、P=0.7079) 和非参数Wilcoxon秩和检验(Z=1.2143, P=0.2246) 对水源水中检出草甘膦的样品进行统计分析, 其检出率和含量结果无统计学意义, 利用Fisher精确检验对三地区被检查的样品进行统计学分析, 其不同地区间检出样品差异有统计学意义(P < 0.0001)。
结论尽管生活饮用水均未检出草甘膦, 考虑到草甘膦是一种高效低毒和广泛使用的除草剂, 仍需加强对生活饮用水中草甘膦的检测。

Abstract:
Objectives To investigate the contamination of glyphosate in drinking water and source water in Henan Province.
Methods The detected results were statistically analyzed by Fisher exact test and nonparametric Wilcoxon rank sum test.
Results Based on the type of water source, no statistical difference was observed on the results analyzed by Fisher exact test(P=0.7540、P=0.7079) and nonparametric Wilcoxon rank sum test (Z=1.2143, P=0.2246). On the other hand, based on the position of the city, there was a statistical difference on the results analyzed by Fisher exact test (P < 0.0001).
Conclusions Considering that glyphosate is a high effective and low toxic and widely used pesticide, and glyphosate has not being detected in drinking water samples, monitoring the quality of drinking water for glyphosate is still to be strengthened.
