An investigation of air pollution in the Tehran metropolitan area between 1992-2000 indicated that there are significant amounts of nitrate ion (NO3-), over 30 kg/ha/year, deposited as wet deposition, compared to 13 kg/ha/year in the Chitgar Parkland near the Tehran metropolitan area. The amount of NO3- in warm seasons is twofold that of cold seasons, and there was a significant difference between cold and warm seasons. Annual wet deposition of ammonia (NH3) was 10 kg/ha/year in the Chitgar Parkland.
