Abstract: The range of influence of vehicle exhaust Pb on Reaumuria soongorica by the road is 30 meters. The background value of Pb in the leaves of R. soongorica in the Kalamili Mountain Reserve is 0.61—0.77mg·kg-1, its average is 0.6869mg·kg-1. The relationship between Pb content in leaves and distance to the road is described as: Cx=0.6869+0.3761exp(-0.034x), r=0.87. In average, Pb content in leaves of R. soongorica reduces 3.4% per meter from the road.
