求翻譯:對于交通區,成份1解釋的因子為鉻、銅、汞、鎳、鋅;成份2解釋的因子為鎘、鉛;成份3解釋的因子為砷。銅、鉛和鋅主要來自交通污染,其中,鋅來源于汽車輪胎的老化磨損、 汽油、車體的磨損等,銅污染大多因為汽油、車體的磨損等,鉛來源于汽車尾氣排放, 車燈汞燈等氣體放電燈的廣泛使用,這使得表層土壤中汞的含量遠遠超標。汞多用于汽車的燃煤因子,在燃煤過程中產生大量廢氣。與Hg污染來源相似,砷污染主要來源于燃煤源。是什么意思?![]() ![]() 對于交通區,成份1解釋的因子為鉻、銅、汞、鎳、鋅;成份2解釋的因子為鎘、鉛;成份3解釋的因子為砷。銅、鉛和鋅主要來自交通污染,其中,鋅來源于汽車輪胎的老化磨損、 汽油、車體的磨損等,銅污染大多因為汽油、車體的磨損等,鉛來源于汽車尾氣排放, 車燈汞燈等氣體放電燈的廣泛使用,這使得表層土壤中汞的含量遠遠超標。汞多用于汽車的燃煤因子,在燃煤過程中產生大量廢氣。與Hg污染來源相似,砷污染主要來源于燃煤源。
