[目的 ]探讨非职业接触人群血铅和血镉水平及其变化趋势 ,为评估分析环境铅和镉污染程度和污染来源提供科学依据。 [方法 ]按 WHO生物监测方法和程序于 1 982～ 1 998年对西安市非职业接触女性连续进行了血铅和血镉监测 ,并对相关人群做了一次性摸底对照监测。 [结果 ] 1 7年间女性血铅由 0 .2 80μmol/L升至 0 .438μmol/L,血镉由 4.45 nmol/L升至 6.32 nmol/L,上升幅度分别是 56.4%和 42 .0 %。人群对比显示城市女性血铅血镉水平显著高于乡镇对照组女性 (血铅 :P<0 .0 1 ;血镉 :P<0 .0 0 5)。 [结论 ] 1 982～ 1 998年间西安市生活环境中铅和镉污染在逐渐加重 ,除环境因素外 ,某些个体因素可能也会影响血铅和血镉浓度
[Objective] To explore the changes of blood lead and blood cadmium in non-occupational exposure population and provide scientific basis for assessment and analysis of environmental lead and cadmium pollution and sources of pollution. [Methods] According to WHO biological monitoring methods and procedures, blood lead and blood cadmium monitoring was continuously conducted in Xi’an city from 1986 to 1998 for women with non-occupational exposure. [Results] The blood lead increased from 0.280μmol / L to 0.388μmol / L and the level of cadmium was increased from 4.45nmol / L to 6.32nmol / L in 17 years, with a rise of 56.4% and 42.0% respectively. The crowd comparison showed that the levels of blood lead and cadmium in urban women were significantly higher than those in the township control group (blood lead: P <0.01; blood cadmium: P <0.05). [Conclusion] The lead and cadmium pollution in living environment of Xi’an from 1982 to 1998 gradually aggravated. Apart from environmental factors, some individual factors may also affect the levels of blood lead and blood cadmium
