Absorption of atmospheric C2–C5 aldehydes by various tree species and their tolerance to C2–C5 aldehydes

To estimate the effect of tree planting on atmospheric C2–C5 aldehydes, a study was made on the absorption of, and tolerance to, C2–C5 aldehydes by various tree species. The absorption rates ranged from 10.2 for acetaldehyde (Japanese black pine) to 107 ng dm−2 h−1 ppb−1 for n-valeraldehyde (locust) at 1000 μmol of photons m−2 s−1. The absorption rates of C2–C5 aldehydes increased in the following order: coniferous tree species
