润滑油添加剂生物毒性的研究

采用发光细菌作为试验生物,对几种典型发动机润滑油添加剂的生物毒性进行了试验研究。该方法为油类污染的生物监测和水生生态毒理学研究提供了新的试验生物模型。试验结果表明，添加剂具有一定的生物毒性且差异很大,其使用范围和比例受到生物毒性指标的限制；润滑油的生物毒性主要取决于其添加剂的生物毒性。这对添加剂的合理使用具有指导意义,亦为研究低生物毒性、环境友好润滑油提供了基础数据.研究中发现，一般润滑油添加剂水融合一组分（WAF）溶液载荷率与其相对发光度呈指数递减关系，并给出了基本经验公式。

Studies on the Ecotoxicity of Lubricant Additives

The experimental studies on the ecotoxicity of several typical lubricant additives were conducted by applying luminescent bacteria as subjects.The approach provides update experimental model for biological inspection of varied oil pollution and studies on aquatic ecological toxicity.The results of the experiments show that additives have characteristics of toxicity and they differ dramatically,their applying scope and proportion are limited by the indexes of ecotoxicity;the ecotoxicity of lubricants are mainly decided by additives'.What was found in the experiment has an instructive meaning for reasonable application of additives and it accumulates some basic data for environmental friendly lubricants.During the studies,the principle of mitosis coefficients decrease was initially detected between water accommodated fraction(WAF) loading rate of ordinary lubricant additives and its relative luminosity,and basic formulas were presented.
