...most severe damage has occurred at high altitudes to such trees as the red spruce and Fraser and balsam firs. The summits of Camels Hump and Mount Mitchell are enshrouded for as much as a quarter of the year in clouds, which are loaded with acidic chemicals and toxic heavy metals. Says Arthur Johnson, a soil expert at the University of Pennsylvania: "Vegetation essentially combs polluted moisture droplets out of the clouds." Mountain tops at this altitude are also exposed to high concentrations of ozone and get more rain, which washes chemicals onto the trees. "Most people think of remote...
Researchers speculate that chemicals may work their damage in several ways. The excess ozone might open the pores of leaves, allowing acid rain to leach vital nutrients. Or acid rain may cause harmful changes in the chemical composition of the soil. Rain may also deposit toxic heavy metals that damage plants' root systems. Says Richard Phipps of the U.S. Geological Survey: "The darn thing is a heck of a lot more complex than we ever thought...
