Regional tree growth reductions due to ambient ozone: evidence from field experiments

Experimental evidence from open-top chamber field studies indicates that ambient ozone levels at levels below the ambient air Quality standard of 235 mg/cu M causes significant reductions in sapling poplar growth. However, growth reductions for Populus deltoides and Robinia pseudoacacia were not sig...

Description
Summary:Experimental evidence from open-top chamber field studies indicates that ambient ozone levels at levels below the ambient air Quality standard of 235 mg/cu M causes significant reductions in sapling poplar growth. However, growth reductions for Populus deltoides and Robinia pseudoacacia were not significant. Reductions in productivity and height growth occurred without visible symptoms of foliar injury and at O 3 levels below current standards. If this invisible injury is typical in other tree species, the extent of O 3 induced forest damage may presently be greatly underestimated.
