Abstract
An investigation was carried out to establish the changes in the lead content of trees and shrubs on the Margaret island in Budapest as a response to the reduction in motor-vehicle traffic introduced in 1974. Compared to samples of the control area (Vacratot) the Margaret island samples were found to have a considerable higher lead content. As a consequence of the traffic modifying measure a 30% decrease in the lead content of the samples was verified. The lead pollution did not involve changes in the chlorophyll content of samples. Accumulation of lead pollution is a specific feature. Lead pollution is accumulated to a great extent (multiple of other plants) by the pilose-leaved CELTIS occidentalis, the pinnate-leaved FRAXINUS angustifolia, ssp. pannonica and the undulate-leaved AESCULUS hippocastanum as well as from among the evergreen by the stellate-hair HEDERA helix. The green belt bordering the roads by its active lead cumulation plays an important role in lessening the plumb pollution of areas more distant from the road. 14 references 3 tables.
