主 题：Trace metal Road and facade Wash-off Snowmelt Bayesian network
摘 要：Particulate-associated trace metals have been regarded as an important pollution source for urban surface ***,Pb,Cu,Zn and total solids(TS)washed off two different surfaces(low-elevated facade and road surfaces)under two kinds of antecedent environmental conditions(dry and snow-melting)were determined in this ***-vacuuming sweeping(WVS)and surface washing(SW)methods,representing the maximum pollution potential and common rainfall-induced wash-off condition respectively,were used to collect the particulate *** result shows that the wash-off concentrations of trace metals were found in the order of Cd(2.28±2.08 mg/l)38% and 79% of metals and TS concentrations in the facade surface and road surface runoff *** wash-off concentrations of Cd,Cu,and Zn on the road surface 45e780% higher than those on the facade *** sensitivity analysis based on the Bayesian network indicates that the wash-off concentrations of metals were mainly dependent on the antecedent environmental conditions or the surface properties while the sampling methods had a minor ***,to accurately model the pollutant migration in the surface runoff requires an improving method considering different surfaces and antecedent environment conditions.
