Elevated dissolved and total concentrations were measured during snowmelt in correlation with high electrical conductance reflecting the use of road salt as a deicing agent. Event mean concentrations were positively correlated to wind speed and negatively correlated to rainfall depth in the two antecedent weeks. A mild first flush of dissolved metals was observed in most events, with 40–50% of pollution mass being discharged in the first 30% of runoff volume. Particulate-bound heavy metals, however, only exhibited first flush during intensive snowmelt. A strong linear correlation was observed between particulate-bound heavy metals and total suspended solids (TSS) (R²=0.8–0.9), corresponding to 0.45, 0.22, 0.05, and 0.06  μg/mg TSS slope for Zn, Cu, Cr, and Ni, respectively. Overall, the pollution levels were moderate compared with residential catchments in northern Europe and North America, which may constrain runoff treatment efficiency.]]> Thu, 05 Mar 2015 17:48:08 GMT https://trid.trb.org/View/1344209 First Flush Reactor for Stormwater Treatment for Elevated Linear Transportation Projects https://trid.trb.org/View/919748 Thu, 17 Jun 2010 07:17:58 GMT https://trid.trb.org/View/919748 Particle Size Distribution in Highway Runoff https://trid.trb.org/View/759672 Fri, 26 Aug 2005 23:16:45 GMT https://trid.trb.org/View/759672 Mass Loading of First Flush Pollutants with Treatment Strategy Simulations https://trid.trb.org/View/759652 Fri, 26 Aug 2005 09:53:44 GMT https://trid.trb.org/View/759652 FIRST FLUSH CONCEPTS FOR SUSPENDED AND DISSOLVED SOLIDS IN SMALL IMPERVIOUS WATERSHEDS https://trid.trb.org/View/744765 Sun, 14 Nov 2004 00:00:00 GMT https://trid.trb.org/View/744765
