The impacts of ambient ozone pollution on crops in the Mediterranean countries have been recorded regularly in the so-called grey literature of UN/ECE Workshop Reports for the Convention on Long-range Transboundary Air Pollution, and less frequently in the peer-reviewed literature. This short communication reviews such records and shows that ambient ozone episodes have been reported to cause visible injury on 24 agricultural and horticultural crops grown in commercial fields including three of the most important crops in the region (wheat, maize, and grapevine). On one occasion, the damage was so extensive that complete crop loss occurred in commercial glasshouses of Butterhead lettuce in one area of Greece. Experiments with open-top chambers have indicated that ambient ozone caused 17-39 % yield loss in crops such as wheat, bean, watermelon and tomato. The applicability of the long-term critical level of ozone described by Fuhrer et al. (Environ. Pollut. 97 (1997) 91)for the Mediterranean areas is also considered. (C) 2001 Elsevier Science Ltd.
