Abstract
An estimate of the annual global methyl bromide (CH3Br) emissions from automobile exhausts has been determined by extrapolating the results of a field study conducted in the United Kingdom (UK). A strong linear correlation was observed between the CH3Br and carbon monoxide (CO) c oncentrations of roadside air in three cities. This correlation;md kno wledge of the UK CO emissions was used to estimate the source strength of CH3Br from automobile exhausts in the UK (0.04 Monnes yr(-1)). Fur ther extrapolations lead to a.value of 1.5 ktonnes yr(-1) (with an upp er limit of 3.0 ktonnes yr(-1)) of CH3Br released globally to the atmo sphere from automobile exhausts.
