The ecological effects of diffuse air pollution from road transport (ENRR580)

Little is known regarding the ecological impacts of diffuse air pollution from individual roads, including the effects on designated wildlife sites in their proximity. This information in required by English Nature in order to provide advice to the relevant organisations (eg Highways Agency, Defra, DfT) on the potential environmental impacts of new road developments. This report provides an evaluation and synthesis of the evidence (both published and unpublished) for local effects of air pollution from motor vehicles, primarily on vegetation.
