The effect of burnt automobile gases on the enzyme activity of leached cinnamon forest soil was studied in the course of two years. In the conditions of a rather slight pollution of the soil on the sides of the highway Sofia-Kulata, branch Sandanski, the heavy metals plumbum and zink have no obvious effect on the enzyme activity of leached cinnamon forest soil. The reaction of invertase activity, which had higher sensitivity to plumbum and zink content could be used to a certain extent as a diagnostic index for the pollution of leached cinnamon forest soils.
