Abstract
Abstract Concentrations of bromide in atmospheric particles have commonly been used as an indicator of vehicle-emitted lead, since the two elements are associated in auto exhaust. A depression in the Br Pb ratio from that in fresh auto exhaust has generally been interpreted in terms of an industrial contribution to airborne lead, despite the known loss of bromine from airborne particles during ageing processes in the atmosphere. In this article the available analytical techniques for determination of Br Pb ratios are critically evaluated, and the reported values of Br Pb ratios in ambient air are reviewed. The possible reasons for variability in Br Pb ratios are discussed and recommendations made for the evaluation of Br Pb ratio data.
