【摘要】 沙尘暴的袭击严重污染了城市环境质量 ,对济南市沙尘暴进行采样及化学元素成分分析。沙尘暴期间城市空气中TSP浓度高达 615 5ug/m3 ,是同期的 2 3 .7倍。沙尘暴颗粒物元素以地壳元素为主 ,并且对各种元素有不同程度的富集。更多还原

【Abstract】 The stand-dust storm pollutes air of the city,this article analyses the chemical composition of stand-dust storm of Ji Nan.The TSP volume concentration is 6155 ug/m3 in the period of sampling,that is 22.7 times more than the TSP volume concentration of the same term.The elements of the earth`s crust is the mostly part of stand-dust storm`s chemical composition,and the stand-dust storm`s particles enrich different degree of elements.更多还原
