Description

This dataset contains results of experiments studying the leaching potential of heavy metals from road-deposited sediment (RDS) and three sorptive media (granular activated lignite, granular ferric hydroxide and zeolite) used in storm water quality improvement devices (SQIDs) to retain heavy metals from road runoff. The contaminated RDS and pre-stressed sorptive media were exposed in quiescent batch leaching tests to three different synthetic road runoffs (SRR, SRR+NaCl, SRR+DOM), thereby the effects of de-icing salts and dissolved organic matter were assessed. Samples were withdrawn after (4), 24, 48 and 168 h. The exerted methods are described comprehensively in the associated publication. This dataset contains following items: 1. Metal contents of road-deposited sediment and three pre-stressed sorptive media used in SQIDs 2. Leachates of RDS: pH, electrical conductivity (EC), UVA254, SUVA254, DOC, dissolved Ca, Cd, Cr, Cu, Fe, Mg, Na, Ni, Pb and Zn, and Cl 3. Leachates of three pre-stressed sorptive media: pH, EC, UVA254, DOC, dissolved Cu, Zn, Fe, and Cl
