在工业生产中,人体摄入车间空气中的铅后,血铅浓度是近期接触铅的指标之一,但血铅因接触铅的情况、个人健康状况及饮食习惯等方面的不同而异。所以有人认为血铅是一个不恰当的生物学指标。然而在目前还未找到一项能准确、稳定反映铅接触的生物学指标时,血铅浓度仍然是铅接触的最重要的指标。本文就近年来对血铅浓度及其它铅接触的指标的研究进展简述如下。 In industrial production, blood lead levels are one of the indicators of recent exposure to lead after the body has taken lead in the air of the workshop. However, blood lead varies with lead exposure, personal health and dietary habits. So some people think that blood lead is an inappropriate biological indicator. However, at present, a blood lead level remains the most important indicator of lead exposure at the moment when no biological indicator that accurately and stably reflects lead exposure has yet been found. This article on the recent years, blood lead concentrations and other indicators of contact research progress is summarized as follows.
