摘要: Abstract Green roofs have become a common method to increase water retention on-site in urban areas. However, the long-term quality of runoff from green is poorly understood. This study evaluated stormwater regular (non-vegetated) roof, roof installed 6 months previously, and years ago Portland, Oregon. Samples were taken during every rain event for 10 months, analyzed total phosphorus (TP), phosphate (PO3-4), nitrogen (TN), nitrate (NO-3), ammonia (NH3), copper (Cu), zinc (Zn). Runoff had higher concentrations TP PO3-4 lower Zn compared roof. Average 6-year old 6-month 6.3 14.6 times higher, respectively, than average 13.5 26.6 compare...
