Effects of air pollution on Pinus halepensis (Mill.): Pollution levels in Attica, Greece.
Atmos. Environ. 26, 373-380 (1992)
Air quality in the Athens basin is well known to be poor, damaging building materials and human health, but there is no information available on concentrations or the impact of oxidants on ecosystems in rural areas outside the basin. A short-term monitoring campaign, coupled with a survey using the O3 bioindicator Bel-W3 tobacco demonstrated that phytotoxic concentrations of O3 occurred throughout Attica, within a 75 km radius of the city. There was relatively little injury produced in the industrial centre of the city and maximum injury was found about 40 km to the SE. Visible lesions identical to those of O3 injury were found on Aleppo pine at all sites in the cooler months. In the summer the needles were very chlorotic, possibly due to photo-oxidation of chlorophylls mediated by heat or drought. This chlorosis may mask oxidant symptoms in the summer. NO2 diffusion tube data and needle analysis suggested that the effects of sulphur and NO2 are probably confined to the Athens basin.
