Abstract:
Objective To investigate the relationship between arsenic in drinking water and skin lesions in endemic arsenism area in Shanyin County of Shanxi Province,in order to provide epidemiologic data for further arsenism research.Methods One hundred and eighty-nine endemic arsenism patients and 59 controls were randomly selected in 17 endemic amenism countries in Shanyin County of Shanxi Province.The content of arsenic in drinking water which wa8 collected indoom was half-quantitatively screened by a kit made by Chinese Center for Disease Control and Prevention,then quantitatively determined by HPLC-ICP-MS.Patients of endemic arsenism were diagnosed by "The Standard of Diagnosis for Endemic Amenism"(WS/T 211-2001).Results There were 64.9% (87/134)samples above the arsenic level(50μg/L)of drinking water and the median value of arsenic in drinking water was 91.43 μg/L in 134 water samples.The OR(95%CI)value between arsenic in drinking water and hyperkeratosis,hyperpigmentation,depigmentation was 2.46(1.22-4.94),3.34(1.50～7.44)and 2.86(1.50-5.46),respectively.The prevalence of hyperkeratosis,hyperpigmentation and depigmentation increased,as the arsenic in drinking water increased(≤10,≤50,≤200,＞200μg/L),especially in＞200μg/L group(OR=6.15,13.96,11.41,P＜0.05).The arsenic level in drinking water of Ⅲ degree of depigmentation patients(318.300μg/L)was higher(P＜0.05)than that of 0,Ⅰ and Ⅱ degree groups(86.670,131.800,1 10.590μg/L,P＜0.05).Conclusions Shanyin County is a medial arsenic pollution area. Arsenic in drinking water is considered as a risk factor of skin lesion. The degree of skin lesions increased,as the arsenic in drinking water increased.
