Abstract

The T-N and T-P concentrations of the wet depositions from every event and total depositions were measured in an urban area (at Kobe) and a forest area (at Ikuno) since 1995. The loads of these parameters were estimated and compared to each other.<br>The T-N and T-P concentrations of the wet depositions from every event and the total depositions widely fluctuated, especially for the lower rainfall. The average T-N concentration of the wet depositions from every event and the total depositions at Kobe was nearly twice those at Ikuno, but the average concentrations of T-P in both depositions were the same. Also, the T-N loads for the total depositions at Kobe were about 1.6 times greater than at Ikuno, but the T-P loads were the same.<br>The ratios of the T-N and T-P loads for the wet depositions from every event and the total depositions were 60% and 70%, respectively. Therefore, it was judged that the loads for the total depositions were better than the loads for the wet depositions from every event for estimating the total input to the non-point sources.
