Description
Summary:Analysis of samples of roadside vegetation has often been used as a means of investigating the pattern of lead deposition in relation to such factors as traffic density. Longer term monitoring presents a number of difficulties: differing Pb retention capacities of different kinds of plant material, seasonal and spatial variation in vegetation density, height, live/dead ratio and longevity. Seasonal variation of deposition rates and possibly deposition routes are apparently superimposed on these variables. The problems of interpretation are discussed in the light of experience of a 3-year sampling programme.
