The purpose of this study is to analyze the transport of marine aerosols from sea to coastal farm land.1. The method of measuring marine aerosols: Electrical conductivity of bubbling water increased when wind blew from the sea to the land and marine particle, measured With a laser particle counter, decreased when wind blew from the, land to the sea. The rain cell of 10m -scale were measured with a small marine radar. There is a possibility of measuring large marine aerosols caused to the damage of marine salts with the radar.2. The photosynthetic activity of crop were estimated with chlorophyll fluorescence measurement after salt spray to leaf. The activity of crop were measured within only 1, 2 hour later after salt spray. It is possible to predict an extent of crop damage from salt spray from sea to crop leaf.3. In Karatsu coastal area, amounts of wet and dry deposition from the sea were almost same. The amount of marine substance in snow is smallest on Mitsuse area in Saga prefecture. The water quality of groundwater in Higashimatsuura peninsula was investigated from 1995 to 2002. The nitrate concentration was high and maximum concentration was higher than 60ppm. The nitrate concentration of groundwater was nearly constant from 1995 to 2002 and the bromide concentration of groundwater decreased.

本研究的目的是分析海洋气溶胶从海洋到沿海农田的运输。海洋气溶胶的测量方法：当风从海洋吹向陆地和海洋粒子时，冒泡水的电导率增加，用激光粒子计数器测量，当风从陆地吹向海洋时，电导率降低。用小型船用雷达测量了10米尺度的雨单体。用雷达测量大型海洋气溶胶对海盐的损害是有可能的。采用叶绿素荧光法测定作物叶片盐雾处理后的光合活性。盐雾处理后1、2小时内测定作物活性。预测海水盐雾对作物叶片的损害程度是可能的。在卡拉津沿海地区，来自海洋的湿沉积量和干沉积量几乎相同。在佐贺县的Mitsuse地区，雪中的海洋物质含量最少。1995 ~ 2002年对东松浦半岛地下水水质进行了调查。硝态氮浓度较高，最大浓度大于60ppm。1995 ~ 2002年地下水硝酸盐浓度基本保持不变，溴化物浓度呈下降趋势。
