摘要

The present paper reports a study conducted to compare pollutant loading of runoff waters either collected at the outlet a porous pavement with reservoir structure or coming from a nearby catchment drained by a conventional separate sewerage system, on the experimetnal site of Reze (France). The mean pollutant loads measured at the reservoir structure appear ntoably lower than those measured at the reference catchment. A sampling operation of materials carried out in the porous pavement have confirmed the accumualtion of metals in the porous asphalt and the absence of soil contamination under the reservir structure. An attempt at mass balance for heavy metal distribution into the reservoir structure was made. The maount of metal evacuated at the outlet of the reservoir structure is generally low. Lead is mainly retained by clogging particles and between 57 and 85
