Abstract
The effects of automotive exhausts gases on trees were observed along highway no. 4 in Fukushima. The observed trees were 319 Sophora Japonica (dog pagoda trees) planted on both sides of the highway covering about 4.5 km. The period of observation was between April 1973 through the end of this fall. The young leaves began to bud about April 10, opened about April 17th, and damage began to appear from about May 10; by July and August, damages such as discoloration, shrinking, tearing, and drying up progressed considerably. Some leaves were covered by dusts, as much as 10 wt% of the total weight of the leaves. The trees in the control areas in the suburbs showed almost no damage, except for some slight chlorosis. The chlorophyll measurements increased up to early July and decreased thereafter in the polluted area; the measurements were much higher in the control areas.
