摘　　要：为了更好地了解环境介质中轮胎磨损颗粒释放内源重金属的行为,本研究通过酸、紫外线和臭氧模拟老化的方法,研究老化作用对轮胎磨损颗粒内源重金属释放的影响.实验结果表明:轮胎磨损颗粒内含有多种重金属,其含量顺序为铅>锰>银>镉>镍,其中铅的含量可达110.87~140.44 mg/kg;环境老化作用会加速轮胎磨损颗粒中重金属的释放,同时随着时间的延长其释放量也逐渐增加,增加了轮胎磨损颗粒的环境风险.In order to better understand the release behavior of endogenous heavy metals released by tire wear particles in environmental media,the effects of aging on the release of endogenous heavy metals from tire wear particles were studied by acid,UV and ozone simulated aging.The test results show that there are many kinds of heavy metals in tire wear particles,and the content is Pb>Mn>Ag>Cd>Ni,of which Pb can reach about 110.87~140.44 mg/kg;environmental aging will accelerate the release of heavy metals in tire wear particles,and their release content will gradually increase with time,thus increasing the environmental risk of tire wear particles.
