Up to date, serious effect which caused by air pollutants on horticul¬tural crops were occurred in southern Taiwan. There were 2 groups of air pollutants : one was accident of industrial operation，such as SOx, HF，HC1 or Cl2 etc. These were sources or materials for industry process. Besides, photochemical pollutants such as ozone (03) and peroxyacetyl nitrate (PAN) as another kind of air pollutant. Photochemical pollutants had a very important effect on horticulture. A survey of tropical fruits, vegetables and ornamental crops found many crops were infected and shown 03 or PAN symptoms.
A two year round survey found good qualities of air in southern Taiwan was from June till August. While from summer to autumn, the dry monsoon from North-East caused poor quality of air in Pingtung area, in that period, Kaohsiung’s air quality was better than Pingtung prefecture. When weather became wet, wet monsoon enforced wind to mountain area of southern Taiwan and caused poor air quality on those areas.
Many horticultural crops affected by poor air quality such as cucumber, muskmelon, flowers and vegetables. Fruit trees also affect and show symptoms on fruits as guava and Indain jujube. Photochemical pollutants might be cause plant mineral deficiency as calcium deficiency and showed symptoms and caused epidemically. These facts need more studies in the future.
