ABSORPTION OF ATMOSPHERIC PHENOL BY EVERGREEN BROAD-LEAVED TREE SPECIES

To estimate the effect of tree planting on atmospheric phenol, the abs orption of phenol by evergreen broad-leaved tree species was examined. In experiments in which the light intensity was varied for camellia, a linear relationship between the phenol absorption rate and the trans piration rate was observed, showing that atmospheric phenol is absorbe d through the stomata. The absorption rates for five tree species vari ed from 21.3 (camellia) to 52.3 ng dm(-2) h(-1) ppb(-1) (oleander) at 1000 mu mol of photons m(-2) s(-1) and the trees exhibiting higher tra nspiration rates had greater absorption rates of phenol.
