Cores of media were extracted from five 10 year old bioretention cells in Queensland, Auz and tested for a suite of heavy metals: “Although trace amounts of several heavy metals (most prominently Mn and Zn) were found in most of the basins, all heavy metal levels found in the soil were either below detectable limits, or within acceptable limits based on legislated health-based investigation levels.”<ref> Lucke T, Nichols PWB. The pollution removal and stormwater reduction performance of street-side bioretention basins after ten years in operation.
