| Abstract: | Samples from urban trunk road runoff caused by 36 storm events were collected proportionally to the total volume at south second ring road in Xi'an City using self-made volume proportional collecting device from Mar.2009 to Feb.2010.Event mean concentrations(EMC) of SS,COD,dissolved COD,NH4-N,Pb,Zn and dissolved Zn were tested and the annual pollution loads of each pollutant were calculated.Random sampling method was used to investigate the impact of sampling frequency on estimation accuracy of road runoff ... |
