Das Ende der politisierten Sozialstruktur?between O. and other environmental change factors, such as increasing CO. concentrations, increased nitrogen deposition, and drought. Future needs for research include the development of an O. flux model for the most widely used tree species and the assessment of ozone removal by urban forests on a regional and a national scale.

Gaseous Speciesries surrounding China, but also North American countries..Trends in ozone concentrations over the East China Sea were analyzed, based on aerial observations for up to 20 years. A clear increase in ozone was found, particularly in the boundary layer, lower than 1,500 m above sea level.

Acid Depositionation has been observed in areas receiving high acid deposition in China and Japan. Observational data on acid deposition and soil chemical properties should be accumulated for forest areas to ascertain the risk for plants in the region.

Tree Decline at the Somma of Lake Mashu in Northern Japanic air pollutants have influenced plant growth in this area. However, there is still great uncertainty about O. effects on the mountain birch, such as its effects causing stomatal sluggishness, water stresses, and these effects combined with nitrogen input. Further evaluation of these factors is necessary to assess the tree decline.

Effects of Ozone on Crops in China research include improvement of O. impact models and the development of an O. monitoring network to cover the vast areas of crop production in China. The establishment of an air quality standard for protecting crops from O. damage is of critical importance for food security in China.

Effects of Ozone on Japanese Agricultural Crops open-top chambers and controlled-environment growth cabinets; these studies are concerned with the response to and mechanism of ozone influence on various crops. In addition, since the last half of the 1990s, informative studies have been carried out to assess and map critical levels of ozone in relation to Japanese agricultural crops.
