Heavy Metal Mass Accumulation of Urban Surface Dust in Shanghai City
上海城市地表灰尘重金属污染累积过程与影响因素

This paper investigated heavy metal accumulative process of road dust on paved urban surfaces of Shanghai City in April,2006.The data indicate that the surface dust load mean value for traffic area is 12.4(g/m) and the range is 5.04-23.2(g/m);the mean value for the university area is 6.1(g/m) with the range of 3.8-10.0(g/m).The research indicated that long duration and high intensity rainfall has the obvious reduction function to the dust particles load,but the light rain can enable it to increase.Land use ...
