| Sumario: | [EN] In this work, the content of some metals and metalloids in an area with permeable pavements has been determined. First, urban sediment samples from the permeable and impermeable zones have been analysed and the influence that the antecedent dry period has on the accumulation of metals has been observed. Then, the content of metals in the permeable material has been analysed and finally, urban runoff has been compared with the runoff that has passed through permeable pavements. Sediment results show that temporal variable is not significant for most metals and metalloids; however, differences have been observed between the sediments of permeable and impermeable pavement. Regarding water samples, permeable pavements have provided benefits in the physicochemical properties, especially in the reduction of turbidity and thus, of suspended solids (TSS). In dissolved metals, a decreasing trend have been observed for some metals and metalloids, but not for all. It could be considered to compare several samplings after rainfalls of different intensity to obtain more information about the influence of permeable pavements on the quality of urban runoff. |
