Abstract:
Objective To observe the implementation of prevention and control measures for water quality improvement in drinking water type of fluorosis and arsenic poisoning areas,to investigate the operating condition of fluoride-safe water supply projects,and to comprehensively evaluate the project's quality and its effectiveness on water quality improvement.Methods According to the Shanxi Province Drinking Water-Borne Fluorosis and Arsenic Poisoning Fluoride-Safe Water Supply Projects Monitoring Programme,in October 2012-June 2013,45 counties in the province were selected to monitor fluorosis and arsenic poisoning.The running condition of fluoridesafe water supply projects was investigated.One factory water sample was collected to determine the water fluoride (arsenic) concentration.Meanwhile,3 tap water samples were collected to determine the water fluoride (arsenic)concentration in each village,using the Standards for Drinking Water Quality (GB/T 5750.5-2006).Results Totally 1 804 fluoride-safe water supply projects had been surveyed,and 1 673 were in normal condition,accounting for 92.7％.The number of projects supplying fluoride-safe water was 1 328,accounting for 73.6％,benefiting a population of 2.636 779 million people.A total of 2 277 villages were investigated,and 1 826 villages had fluoride-safe water,accounting for 80.2％ of the investigated villagcs.One hundred and forty-five arsenic-safe water supply projects in drinking water type of arsenic poisoning areas were investigated,and 138 were in normal condition,accounting for 95.2％.One hundred and forty-three arsenic-safe water supply projects were qualified,accounting for 98.6％,benefiting a population of 295 240 people.One hundred and fifty-nine villages in drinking water-borne arsenic poisoning areas were investigated,and 156 villages were qualified in water arsenic,accounting for 98.1％ of the investigated villages.Conclusions The qualified rate of fluoride-safe water supply projects is relatively low in drinking water type of fluorosis areas.It has not yet reached the national standard and the management of fluoride-safe water supply projects should be strengthened.The effect of arsenic-safe water supply projects on prevention of drinking water type of arsenic poisoning is significant.
