The effects of variations of water quality on the partioning of heavy metals in a stormwater pond

Paper in proceeding, 1999

Heavy metals are contaminants of stormwater and significant concentrations are found in the dissolved phase, which has a biological importance. Stormwater ponds have been used more and more for treatment of urban runoff to reduce hazardous constituents such as heavy metals. In this study the partitioning of heavy metals in particulate-bound and dissolved phases are investigated in relation to varying water quality parameters such as pH, dissolved oxygen contents and specific conductivity in a stormwater pond in Göteborg, Sweden. The results show a clear variation in heavy metal partitioning and that lead seems to be more extensively particulate-bound due to high specific conductivity.
