为了解普通人群发汞和指甲汞含量现状,探讨人体汞蓄积的影响因素,于2015年3—12月以本校在校大学生生源地普通人群为调查对象,在问卷调查的基础上,运用HydraⅡC测汞仪对研究人群发汞和指甲汞含量进行了测定,对不同地区、不同年龄、不同性别普通人群发汞和指甲汞含量水平进行了相关性分析和风险评价。研究人群发汞含量明显高于指甲汞含量,二者平均含量分别为(0.197±0.191)μg/g,(0.093±0.040)μg/g。头发和指甲汞含量相关性分析显示,二者存在良好的正相关性(r=0.365,P<0.01),20~40岁人群头发、指甲汞含量较高;发汞、指甲汞含量在不同性别之间差异均无统计学意义(P>0.05);随着每天使用美白产品的次数、周食鱼次数、年染发次数的增加,头发汞含量显著升高(P<0.05);指甲汞含量则与周食鱼次数、年染发次数则呈显著正相关关系。沿海地区人群发汞和指甲汞含量明显高于内陆地区(P<0.001),沿海地区居民头发汞暴露健康风险较高,本次调查地区人群发汞含量均未超出1μg/g,提示不同生活习惯对人体发汞和指甲汞含量存在显著影响。
In order to understand the current status of mercury and nails mercury in the general population and to explore the influencing factors of mercury accumulation in human body, from March to December 2015, the general population of college students in our university was investigated. Based on the questionnaire survey, HydraⅡC The mercury analyzer was used to determine the mercury content in the study population and the mercury content in the nails. The correlation analysis and risk assessment were made on the levels of mercury in the population and the nails in different age groups and different gender groups. The study population mercury content was significantly higher than the nails mercury content, the average content of the two were (0.197 ± 0.191) μg / g, (0.093 ± 0.040) μg / g. Hair and nails mercury content correlation analysis showed that there is a good positive correlation (r = 0.365, P <0.01), 20 to 40 years old hair, nails mercury content is higher; hair mercury, nails mercury content in different gender (P> 0.05). The content of mercury in hair increased significantly (P <0.05) with the number of whitening products used per day, the frequency of feeding fish and the number of hair dyeing in each year (P <0.05) There was a significant positive correlation between the frequency of feeding fish and the number of hair coloring per year. The mercury content of mercury and nails in coastal areas was significantly higher than that in inland areas (P <0.001), and the health risks of hair mercury exposure were higher in coastal areas. The mercury content in the surveyed areas did not exceed 1μg / g, suggesting different living Habits have a significant effect on the mercury content of human hair and nails.
