Abstract

Rainwater that has passed over the surfaces of a tree shows a net gain in the loading of many chemical elements. This gain is partly through wash-down of elements trapped from the atmosphere by impaction or adsorption (dry deposition) and partly from elements derived from within the plant tissues (crown leaching).1 Thus, while crown leaching represents part of the cycle of elements internal to the ecosystem, the wash-down of elements derived from the atmosphere represents an input to the site. Clearly it is important to be able to distinguish between internal redistribution and exogenous input, but there is no ready means for making this distinction.
