Download or read book Air Pollution by Photochemical Oxidants written by Robert Guderian and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochemical oxidants are secondary air pollutants formed under the influence of sunlight by complex photochemical reactions in air which contains nitrogen oxides and reactive hydrocarbons as precursors. The most adverse components formed by photochemical reactions in polluted air are ozone (0 ) 3 and peroxyacetyl nitrate (PAN), among many other products such as aldehydes, ketones, organic and inorganic acids, nitrates, sulfates etc. An analysis and evaluation of the available knowledge has been used to characterize the relationships among emissions, ambient air concentrations, and effects, and to identify the important controlling influences on the formation and effects of photochemical oxidants. The biological activity of photochemical oxidants was first clearly manifested during the early 1940's, when vegetation injury was observed in the Los Angeles Basin in the United States. Since that time, as a consequence of the increasing emissions of photochemical oxidant precursors, the photochemical oxidants have become the most important air pollutants in North America. In other parts of the world, for example South and Central America, Asia, and Australia, photo chemical oxidants threaten vegetation, particularly the economic and ecological performance of plant life. According to my knowledge, the first observations of ozone and PAN injury to vegetation in Europe were made by Dr. Ellis F. Darley (Statewide Air Pollution Research Center, University of California, Riverside, California) during a study visit (1963/64) to the Federal Republic of Germany.

Download or read book Effect of acid mist and air pollutants on yellow-poplar seedling height and leaf growth written by Leon S. Dochinger and published by . This book was released on 1985 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: One-year-old yellow-poplar seedlings were treated with acid mist at pH 2.5, 3.5, 4.5, and 5.5 either alone or in combination with 0.1 ppm 03, S02, and N02, or NO2 plus S02. After 4 and 8 weeks of treatment, height, leaf area, and leaf and new shoot weight were determined and growth analysis variables calculated. Height, leaf area, and dry weight decreased with increasing acidity in seedlings treated with acid mist alone. Similar, but smaller reductions occurred in seedlings treated with SO2 and acid mist, but no differences were found in seedlings fumigated with NO2, NO2 plus SO?, or ozone and acid mist. Further studies using different combinations of pollutants and acid mist must be conducted before their apparent interactions can be more accurately assessed.

Available in PDF, EPUB and Kindle. Book excerpt: In the concluding session of the symposium "Acid Deposition, a Challenge for Europe" held in Karlsruhe in September 1983, Dr. GINJAAR, the former Minister of Health and Environmental Protection of the Netherlands, emphasised the need for setting up a concerted research programme including the effects of air pollution on terrestrial and aquatic ecosystems. The Council of Ministers of the European Community in 1984 adopted a revision of the 3rd Community Programme on Environment comprising contract research and concerted action in the field of the effects of air pollution in eco systems. These research areas were also introduced in the 4th R-D Community Programme on Environment, adopted by the Council of Ministers in 1986 and are subject again to contract research and concerted action. The Commission of the European Community is very concerned to increase the effectiveness of researcn projects carried out within the national programmes, and those undertaken at the Community level. The Commission tends to develop an integrated scientific approach, including not only the physico-chemical behaviour, the transport and the deposition of airborne pollutants but also the effects of these pollutants, in particular on living organisms and ecosystems. With regard to the specific issue of the effects, the Commission is trying to develop and strengthen a multi-disciplinary approach associating biologists, pathologists, eco physiologists, and specialists of soil sciences, within the concerted action, as well as within coordinated research projects.

Download or read book Air Pollution Impacts on Plants in East Asia written by Takeshi Izuta and published by Springer. This book was released on 2017-02-13 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the only book to offer an up-to-date overview of air pollution in East Asia and the effects of air pollutants such as ozone, acid deposition and aerosols on Asian crops and trees. It is unique in that it discusses the fundamentals of environmental plant science and research advances in the area at the plant ecophysiology level. It addresses various topics, including gaseous air pollutants such as ozone; soil acidification and atmospheric nitrogen deposition due to acid deposition; PM2.5 and the effects of air pollutants on growth, yield and physiological functions such as photosynthesis of crops and trees in East Asia. It is a valuable resource for environmental scientists, plant scientists, government officials, industrialists, environmentalists, undergraduate and graduate students and anyone interested in the application of the latest findings to agricultural production and protection of forest ecosystems in Asia. It also provides useful information for professionals involved in research, development, production, processing and marketing of agricultural products, including those in developing countries who are interested in advanced environmental science in this field.
