We characterized the physical transport of soil, and therefore contaminants attached to the soil, onto vegetative surfaces due to rainsplash. Soil accumulation by tomato plants (Lycopersicon esculentum) was investigated as a function of soil particle size, rainstorm characteristics, foliage height, surface area and canopy cover of the plants. No soil particles greater than 105 micron in diameter were detected on the plants. Most of the soil was splashed no higher than 40 cm above the ground surface. Linear relationships were observed for concentrations of less than 53 micron soil on vegetation and certain rainfall characteristics. Data from this study, as well as ancillary calculations, provide evidence that a significant fraction of surficial contamination of foliage may be attributed to the rainsplash mechanism.
我们对因雨滴飞溅导致的土壤以及附着在土壤上的污染物向植物表面的物理迁移进行了表征。研究了番茄植株（番茄）的土壤积累情况，它是土壤颗粒大小、暴雨特征、植株叶片高度、表面积和冠层覆盖度的函数。在植株上未检测到直径大于105微米的土壤颗粒。大部分土壤溅落高度不超过地面以上40厘米。对于植被上直径小于53微米的土壤浓度与某些降雨特征之间观察到了线性关系。本研究的数据以及辅助计算提供了证据，表明叶片表面污染的很大一部分可能归因于雨滴飞溅机制。
