ABSTRACT
Objective To investigate the prevalence of endemic arsenicosis and the progress made of control measures in China in 2006 so as to provide basis for endemic arsenicosis control in China.Methods The surveillance was carried out according to"the National Survey Scheme of Endemic Arsenicosis".The surveillance was carried out according to the national survey scheme of endemic arsenicosis.14 drinking water type of and 3 coal-burning type of endemic areas were selected.The fulfillment and effects of control measures,and prevalence of arsenicosi were sarveyed.Arsenic contents in drinking water,corn,chilli,coal and urine were detected by silver Burveyed had improved water was 1.04%(3/288)0f tlle pmjects fail to work,86.67%(247/285)of water arsenic concentration was aualifted.All the 8746 stoves were improved in the survey spots of coal-burning area.The rate of using high arsenic coal in survey spots was 51.08%(355/695).The qualified rate of stove was 75.05%(358/477), Among 14 survey spots,water arsenic concentrations of 6 spots were within safety threshold≤0.05 mg/L,in a rate of 42.86%.Arsellic concentration in some ofthe coal samples from Shiyakou Village,Anlong County was over 100 mg/kg. All chilli arsenic contents(mean)of 3 survey spots outnumbered national standard(≤0.5 mg/kg)and corn arsenic in drinking water areas in 2006,some of the pmjects are running out.The population of survey spots is still exposed of coal store tends to decline.Food arsenic pollution is mitigated compared with last year,especially chili.
