Abstract
Damage to Japanese cedar trees has been found in central Japan, and the region of highest damage extends along a curved path from Tokyo to the Central Mountainous Region. This region also corresponds to the region of highest oxidant levels. The high oxidant levels in this region occur during clear summer days when locally induced large-scale winds develop and transport polluted air from the Tokyo metropolitan area ~150 km inland. A detailed transport/chemistry/ deposition model (the STEM-II model) is used to provide analysis of the effect of reduction in NOx, SOx, and non-methane hydrocarbon (NMHC) emissions on the dry deposition and surface concentrations along the path of long-range transport. NOx emission reductions are shown to result in a reduction of nitrate deposition and an increase in O3, H2O2, and PAN deposition in this region. Reducing NMHC emissions results in a decrease in O3 exposure.
