Abstract

Lead and cadmium concentrations both in the air and precipitation have been monitored since the early 80's under regional background conditions in Hungary. Lead and cadmium are attached to aerosol particles mostly in fine size range. Hence, they can be transported hundreds or more kilometers from their sources before gradually being removed from the atmosphere by dry or wet depositions. The geographical origin - country-to-country budgets - of lead and cadmium deposited in Hungary was estimated by means of a European- scale long-range transport model. 1 Introduction In recent years there has been an increased interest in trace metals in the atmosphere and the environmental effects of their deposition. This is to large extent because heavy metals can accumulate in the biosphere and ma
