- W90822172 abstract "Air pollution research needs of agriculturists and foresters in Canada will vary depending upon the sources and kinds of pollutants, the vegetation type, and the phytotoxicological response. Air pollution poses a large number of problems as a result of man's activities and research is necessary to solve these problems with the ultimate aim of improving the health and welfare of man. Agricultural and forested lands in Canada are subject to a wide variety of air pollutants, and each poses a particular problem. The broad aim of air pollution vegetation research is to be able to detect, identify, describe and prevent or control injury to vegetation. In this paper air pollution research needs in agriculture and forestry are segregated into five main sections, each with a number of subtopics. (1) The first area requiring new and continuous research is the development of air quality criteria and standards with respect to vegetation. (2) The second area is in the diagnosis of air pollution injury. (3) Following detection of air pollution injury, study methods are required to determine the severity and extent of vegetation damage. (4) The prevention and control of air pollution injury to vegetation has high priority in agricultural and forestrymore » research needs. The development of plant species and varieties resistant to air pollution should be accelerated. Research is needed in the development of effective anti-pollutant sprays. Research is needed to determine toxicity, persistence, and safe methods of applying agricultural chemicals and to find suitable alternatives.« less" @default.
