In view of present concern over air pollution, spatial models and display of chemicals in rainwater becomes increasingly important. The publication attempts a contribution at three levels: (1) Understanding the processes which are responsible for the negative exponential relationship between elemental concentration and precipitation, (2) attempting to quantify the negative exponential function for seven common elements and compounds, and (3) applying this information to produce computerized spatial displays (maps) of washout, rainout and total wet fallout patterns in the United States for several chemicals.
