| Abstract: | To investigate the internal exposure levels of Nickel, Stannum, Antimony and Thallium in blood and urine of the population in some areas of Shaanxi Province,so as to analyze the population distribution characteristics.Methods 720 people in 5 counties (districts) were selected in Shaanxi Province by multi-stage stratified random sampling in 2017.Blood and urine samples were collected and the contents of Nickel(Ni),Stannum(Sn), Antimony(Sb)and Thallium(Tl) were measured to analyze the distribution differences among different genders, ages and regions. The Mann-Whitney U test was used for the comparison of two independent samples, and the Kruskal-Wallis H test was used for the comparison of multiple independent samples.Results The geometric means (GM) of Ni concentration in blood and urine in some areas of Shaanxi province were 0.59μg/L and 1.08μg/L respectively,and the concentrations of Ni in blood and urine in urban (0.65μg/L, 1.41μg/L) were higher than those in rural (0.55μg/L,1.02μg/L)(Z=-6.241,-2.072,P<0.05). The concentration of urinary Ni in the age groupof 12 years and above was higher than that in other age groups, and the difference was statistically significant (H=17.532, P<0.05). The GM of urinary Sn was 0.29μg/L, and the content of urinary Stannum in 3 ages and older group was statistically higher than that in other age groups(H=77.147, P<0.001). The GM of blood Sb and urinary Sb were 1.63μg/L and 0.06μg/L respectively. The concentrations of Sb in blood and urine in urban (1.8μg/L1,0.07μg/L) was higher than those in rural (1.49μg/L,0.06μg/L) (Z=-9.680, -4.327,P<0.05). The GM of blood Tl and urinary Tl were 0.03μg/L and 0.18μg/L. The concentration of Tl in blood in urban (0.02μg/L) was lower than that in rural (0.03μg/L) (Z=-7.701,P<0.05), while the urinary Tl was statistically different in distributions of gender, region and age (Z=-4.622, Z=-2.425, H=29.624, P<0.05). Conclusion There are statistical differences in blood Ni, Sb and Tl among different regions, while the differences of urinary Tl among people of different genders, ages and regions are statistical. This survey provides reliable data of Ni, Sn, Sb and Tl among people in some areas of Shaanxi Province. |
