Abstract:
Objective By analyzing the levels and distribution characteristics of whole blood metal exposure in four districts and counties in Xinjiang,a population baseline data was established to provide scientific basis for the development of environmental hygiene and health prevention and control intervention measures.Methods Using a stratified random sampling method,252 residents aged 3-80 were selected from four regions in Xinjiang(Altay City,Shuimogou District,Urumqi City,Wuqia County,and Zepu County).1ml of fasting venous blood was collected and the whole blood metal concentration was detected by inductively coupled plasma mass spectrometry(ICP-MS).SPSS21.0statistical software was used to analyze the differences in whole blood metal exposure levels.Results A total of 967 qualified samples were screened.Include metal elements with a detection rate of 75％for lead,manganese,and nickel in whole blood for analysis.Blood lead M(Q1,Q3)is 15.91(11.47,22.41)μg/L;blood manganese M(Q1,Q3)is 10.11(8.29,12.56)μg/L;blood nickel M(Q1,Q3)is 0.90(0.63,1.17)μg/L.There were statistically significant differences in the concentrations of blood lead,blood manganese,and blood nickel in different regions(H were 16.171,27.642,87.690,respectively,P＜0.05).There is a statisti-cally significant difference in blood nickel levels between urban and rural areas(H=19.261,P＜0.05).There were statistically signifi-cant differences in blood lead and blood manganese levels among different ages(H were 31.786,67.631,P＜0.05).There is a statisti-cally significant gender difference in blood lead and blood manganese levels(H were 31.255,19.921,P＜0.05).Conclusion Resi-dents in four districts and counties in Xinjiang have certain levels of internal exposure to lead,manganese,and nickel,and there are re-gional,urban-rural,and population differences.It is suggested that residents in Xinjiang may be at a potential risk of low-level expo-sure to multiple metals in the environment,and further research is needed.
