“…The mean EMCs for TN, TKN, NH 3 -N, NO 3 -N, TP and orthophosphate were 1.57, 1.19, 0.32, 0.36, 0.19 (Kim et al, 2007a) for which the nature of the impermeable surface was not identified. Rushton (2002) calculated the maximum nutrient loadings (kg ha -1 .year) released from an asphalt car park surface to be 2.04, 0.57, 0.81, 0.34 and 0.19 for TN, NH 3 -N, NO 3 -N, TP and orthophosphate, respectively.…”
