Citation: Yufen, R., Xiaoke, W., Zhiyun, O., Hua, Z., Xiaonan, D., & Hong, M. (2008). Stormwater Runoff Quality from Different Surfaces in an Urban Catchment in Beijing, China. Water Environment Research.
Study description: This study examined the pollutants in stormwater runoff from a number of surfaces (roof, lawn, local/small road, and heavy traffic road).The concentrations of pollutants was assessed across a number of rain events and between the different surface types.

Cause term/trajectory: Land use/land cover - urban (Change)
Cause description: Different surface types assessed - lawn, roads, roofs
Effect term/trajectory: Water quality - nutrients (nitrogen) (No change)
Effect description: Total nitrogen (TN) was not significantly different in runoff from the different surface types.
Response measure type: F statistic/ratio

Source data: Field
Study type: Observation
Study design: Control/reference vs. treatment/impact (no before)
Number of independent control or reference sampling units: 14
Number of indendent impact or treatment sampling units: Control: Rainwater collected in 3 polyethylene vessels (3 sites). Treatments: Roof runoff (3 sites), road runoff (4 sites), lawn runoff (1 site), heavy traffic road (3 sites)
Sample size used in analysis: Sample size varies across different surface types.
Design description: Sample size/ number of rain events sampled unclear.
