Abstract

The removal of particulate lead from the air by a roadside windbreak of white pine containing 8 rows of 25-year-old trees and 27 m in depth was studied. Knowledge of particulate trapping and retention was gained by atomic absorption spectrophotometry of the lead burden of foliage and twigs of various ages adjacent to and far from the road. The effectiveness of the windbreak was also shown by comparison of the lead content of the soil beneath the windbreak with that of an adjacent open, undisturbed field.
