Analyses on Heavy Metal Pollution of Drinking Water from Purifying Agents in Henan Province in 2008—2012

摘要

摘要:
目的了解河南省生活饮用水化学处理剂重金属污染状况。
方法采用《生活饮用水卫生规范》(2001) 规定的方法, 对2008-2012年河南省饮用水化学处理剂进行砷、铅、汞、镉、铬、银、硒含量测定, 并用SPSS 13.0软件对测定结果进行分析。
结果 275份样品综合评定合格率为51.64%;送检样品合格率44.81%, 明显低于封检样品合格率60.33%;不同品种间综合合格率分别为聚氯化铝47.90%、聚氯化铝铁58.33%、聚硅硫酸铝64.29%和其他类50.00%;砷、镉、铬、铅、银、硒和汞总合格率分别为66.18%、98.18%、98.55%、68.73%、98.91%、98.55%和83.64%。
结论生活饮用水化学处理剂重金属超标较严重, 其超标的主要原因与原材料及生产工艺有关。

Abstract:
Objectives Get to know the heavy metal pollution of drinking water from purifying agents in Henan province.
Methods Detecting the content of As, Pb, Hg, Cd, Cr, Ag and Se in purifying agent samples and analyzing the detected results with SPSS 13.0 software.
Results The pass rate was 51.64% for all 275 samples. The pass rate was 44.81% for the samples brought by the manufacturer of purifying agents, which was much lower than 60.33% for the samples brought by supervising departments. The pass rates were 47.90%, 58.33%, 64.29% and 50.00% for polyaluminium chloride, poly-aluminum-ferric chloride, poly-silicic-aluminum sulfate and others, respectively. The pass rates were 66.18%, 98.18%, 98.55%, 68.73%, 98.91%, 98.55% and 83.64% for As, Cr, Pb, Ag, Se and Hg, respectively.
Conclusions Heavy metal pollution of drinking water from purifying agents in Henan province was serious and the pollution was mainly from the raw materials and the process of production.
