The exchange of acetaldehyde between atmosphere and plant leaves includes three processes: 1) acetaldehyde is emitted from plant leaves; 2) acetaldehyde in the atmosphere deposits to the leaf-surface; and 3) acetaldehyde is absorbed and metabolized by plants. The physiological and environmental factors which controlling these processes were reviewed. Acetaldehyde emission from plants in some unfavorable environment functions as external signal for within-plant communication, serving also a systemic response to local damage. The mechanism of acetaldehyde production was also discussed. With the capability of absorbing acetaldehyde, plants can be used to detoxify the air. Phytoremediation will be one of the most promising approaches for cleaning up the air organic pollutants. While, plants are also important pools of acetaldehyde production, especially under environmental stresses such as flooding and anaerobic condition.
