Abstract
The precipitaion was collected using a simple sequential sampling apparatus, each 5 ml per every 1 mm precipitaion in Komaki area, Aichi during the period from January, 1993 to December, 1997. And pH and electric conductivity of the precipitaion were measured by simple apparatuses. The range of annual average pH value was 4.2-4.8, and that of H+ depositions was 16-80 mm⋅m-1⋅year-1. It was found that the outline of chemical properties of precipitation for some areas could be analyzed by long-term monitoring with the simple method.
