Abstract
Aerially dispersed heavy metals from a high speed motorway have been shown to be entering an urban arboretum. Lead (Pb) and Cd were found as remote as 930 m from an east-west, multi-lane motorway. Both Pb and Cd were bioavailable to earthworms (Eisenia foetida) and both metals were more concentrated in surface soils than at depths of 1 meter.
