目的了解某国家级重金属污染重点防控区人群体内铬水平及健康情况。方法在石家庄市某县污染区随机选择94名居民为环境暴露组,在非污染区随机选择31名居民为对照组,进行流行病学调查,并采集晨尿,采用石墨炉原子吸收法测定尿中铬含量。结果环境暴露组人群尿中铬含量高于对照组(P<0.05);暴露组高年龄段人群尿中铬含量高于低年龄段,男性尿中铬含量高于女性,但差异均无统计学意义(P>0.05)。除呼吸系统疾病两组构成比不同外(P<0.05),其他疾病构成差异无统计学意义(P>0.05)。结论加强该金属污染重点防区环境暴露组人群体内铬含量的监测,早期发现其健康损害。
Objective To understand the chromium level and health status of population in a national heavy metal pollution prevention and control area. Methods 94 residents were randomly selected as environmental exposure group in a contaminated area in a county of Shijiazhuang and 31 residents were randomly selected as the control group in the non-contaminated area for epidemiological investigation and morning urine was collected. The urine samples were determined by graphite furnace atomic absorption spectrometry Chromium content. Results In the exposed group, the urinary chromium content was higher than that of the control group (P <0.05). The urinary chromium content of the exposed group was higher than that of the younger age group, while the urinary chromium content of the male was higher than that of the female, but the difference was not statistically significant Significance (P> 0.05). Except for the differences in the composition of respiratory system diseases between the two groups (P <0.05), there was no significant difference in other diseases (P> 0.05). Conclusion To strengthen the monitoring of chromium content in the environmental exposure group of the key pollution zone of metal pollution, early detection of their health damage.
