Summary of bioretention water quality cleansing mechanisms for common stormwater pollutants.
Link to this table
Pollutant | Bioretention cleansing mechanism |
---|---|
Total suspended solids | Sedimentation and filtration (e.g. Davis et al., 2009) |
Metals | Filtration of particulate metals, sorption of dissolved metals into mulch layer (e.g. Davis et al, 2009), plant uptake (e.g. Toronto and Region Conservation, 2009) |
Nitrogen | Sorption; uptake by microbes and plant material, uptake into recalcitrant soil organic matter (e.g. Henderson, 2008) |
Phosphorus | Sorption, precipitation, plant uptake, uptake into recalcitrant soil organic matter (e.g. Henderson, 2008) |
Pathogens | Filtration, UV light, competition for limited nutrients, predation by protozoa and bacterial predators (e.g. Zhang et al., 2010) |
Hydrocarbons | Filtration and sorption to organic matter and humic acids, then degraded by soil microbes (e.g. Hong et al., 2006) |
