浙江省城市灰尘重金属分布
Distribution of Heavy Metals Within Znejiang Province for Urban Dust
摘要
Abstract
According to the dust date coming from 11 cities in Zhejiang,Pb,Cu,Zn,Ni,Cr,Co distribution and characteristic on provincial scale were analyzed.The results showed that： For heavy metal content,the southeast and northeast were high,northwest and southwest were low,meanwhile the content increased from the mainland to the coastal cities gradually.Cities reflected different variations and accumulation.Zhoushan had a high heavy metal accumulation and low spatial variability.The accumulation and spatial variability of heavy metals in Hangzhou were high.Coastal cities for Wenzhou,Jiaxing and Ningbo expressed strong accumulation and weak variability.Jinhua was in the position of moderate variation,but Pb,Zn,Cu accumulation were significantly.Ni,Cr in Taizhou and Shaoxing showed a low accumulation and a high spatial variability.Quzhou had high accumulation of Cu and Zn,while a strong spatial variability of Cr and Co.The accumulation and spatial variability for heavy metals in Huzhou and Lishui were low.The accumulation of heavy metal in urban dust on provincial scale was the order of Cu Zn Pb Cr Co Ni,at the same time,Pb,Zn and Cu showed a strong variation,Co and Cr demonstrated the weak,while Ni was weak in the accumulation and the variation.Human activities is the important factor of heavy metal input.In addition,terrain,surface runoff and monsoon also have strong influence on the migrate,spread and dilution for heavy metal in urban dust.关键词
