Road runoff produced during rainfalls has significant pollutant load. which can cause important environmental impacts on waste and soil. The efficiency of a detention basin for removing heavy metals (Cr. Cu and Zn) in road runoffwas evaluated for 8 rainfalls over one year with different intensities (between 16mmand 103 mm) and durations (higher than 3 hours). https://jalyttlers.shop/product-category/coffee-tables/
