The developed method for mercury speciation analysis has been validated and used for the biomonitoring study of mercury species in human hair. Statistical evaluation proved the reliability of simplified determination of inorganic mercury (difference between total mercury and methylmercury). The results of the validation showed that the method is very well suitable for the determination of both species of mercury in hair for biomonitoring purposes. Non-exposed schoolchildren from three areas in the western and central part of the Czech Republic were chosen as the target group. Tenth of a microgram per gram of the total mercury were generally found in the analyzed hair; values higher than 1 microg g(-1) were detected only exceptionally. Comparable results were obtained for two western areas and differed significantly from those for the third area located in the central part of the Czech Republic. In the areas examined, the mean methylmercury contents amounted to 23-46% of the total mercury in the hair. The results confirm an assumption that exposure to mercury does not pose a significant risk to the population in the Czech Republic.
已对所开发的汞形态分析方法进行了验证，并将其用于人体头发中汞形态的生物监测研究。统计评估证明了简化测定无机汞（总汞与甲基汞之差）的可靠性。验证结果表明，该方法非常适合用于生物监测目的的头发中两种汞形态的测定。选择了捷克共和国西部和中部三个地区未接触汞的学童作为目标群体。分析的头发中通常每克含有十分之一微克的总汞；仅在个别情况下检测到高于1微克/克的值。两个西部地区获得了可比的结果，与位于捷克共和国中部的第三个地区的结果有显著差异。在所检查的地区，头发中甲基汞的平均含量占总汞的23%至46%。结果证实了一个假设，即汞暴露对捷克共和国的人口不会构成重大风险。
