Determination of uranium in drinking water in the vicinity of nuclear power plants by ICP-MS / 中华放射医学与防护杂志

ABSTRACT

Objective To ascertain the concentrations of uranium in drinking water around nuclear power plants.Methods A total of 106 water samples were collected from June 2009 to March 2010 in Jiangsu,Zhejiang,Liaoning and Shandong provinces.Inductively coupled plasma-msgs spectrometry(ICPMS)was applied to determine uranium content in local water source and drinking water.The detection limit of U was 0.8 ng/L.The recovery was 100.9%.Results The uranium concentrations in all samples were less than 15μg/L which was the limit given by World Health Organization(WHO).Conclusions The concentration of uranium in water sources was as followsLiaoning>Shandong>Jiangsu>Zhejiang.The concentration of uranium in drinking water W88 maximal in Shandong Province and minimal in Zhejiang Province.
