目前皮肤污染的最高容许水平,经论证获批准的毒物有16种。定量评价毒物经皮肤作用的实际应用,将能解决一系列重要的实际问题:研究预防毒物经皮中毒和局部作用的更有效的措施;大大提高接触化学物质作业的卫生监督质量,并能客观地评价个人防护工具的效果。这类只适用于经实验证实有剂量-效应;时间-效应关系的毒物,例如有机磷化合物和三硝基甲苯等。如果在每一瞬间不存在这种关系,则不能反映实际作用的危险性,自皮肤表面迅速蒸发所致。如等证明,皮肤表面的丙酮量与其尿内含量无相关。
At present the maximum allowable level of skin pollution, approved by the demonstration of 16 kinds of poisons. The quantitative evaluation of the practical application of poisons on the skin will be able to solve a series of important practical problems: to study more effective measures to prevent percutaneous poisoning and local effects of poison; to greatly improve the quality of hygiene supervision on exposure to chemicals and objectively Evaluate the effectiveness of personal protection tools. This applies only to experimentally confirmed dose-effect; time-effect toxicants such as organophosphorus compounds and trinitrotoluene. If there is no such relationship at each moment, it does not reflect the actual role of the risk of rapid evaporation from the skin surface. As evidenced, the amount of acetone on the surface of the skin has no correlation with its urinary content.
