Air pollutants such as ozone, sulfuric acid, nitrous acid and polycyclic aromatic hydrocarbons were exposed to Japanese red pine, petunia, tomato, strawberry, eggplant and kidney bean for 1-3 months. Single or multiple pollutants were exposed on the plants in open top chambers or greenhouse. Photosynthetic activities, visual injuries and growth rates of the plant samples were measured before and after the treatments with these pollutants. Pre-treatment with sprays of scavengers of reactive oxygen species such as mannitol has significantly mitigated negative effects of abovementioned air pollutants on plants. The use of mannitol may be a promising technique to protect higher plants from air pollutants.

日本红松、矮牵牛、番茄、草莓、茄子、芸豆暴露于臭氧、硫酸、亚硝酸、多环芳烃等空气污染物1-3个月。单一或多种污染物暴露在敞顶室或温室中的植物上。在用这些污染物处理之前和之后测量了植物样品的光合活动、视觉损伤和生长率。用甘露醇等活性氧清除剂进行预处理，可以显着减轻上述空气污染物对植物的负面影响。使用甘露醇可能是保护高等植物免受空气污染物侵害的一项有前景的技术。
