Abstract

During the dry periods, many types of pollutant are accumulating on the paved surface by vehicle activities and accumulated various pollutants are inflowing to the near watershed areas for the rainfall periods. Also, the metals, toxic chemicals and sediments originated from bridges could be strongly influenced to the watershed areas during the runoff. The result shows that the EMC ranges for 95% confidence intervals in a bridge land use are $10.12\sim128.09mg/L$ for TSS, $6.07\sim21.15mg/L$ for BOD, $2.10\sim6.70mg/L$ for TN and $0.06\sim0.85mg/L$ for TP.
