With rapid development of modern agriculture, a multitude and large amount air pollutants were generated by agricultural activities, which are becoming more serious issues with regards to pollution [...]
Current increase of atmospheric air pollution rates in developing and developed countries requires efforts to design more cost effective and affordable devices. In developed countries pollution monitoring chambers are available to aid the monitoring process. The culture and the society are aware of the polluted environment side effects and measures have been taken to reduce pollution amounts. M...
391 The ecological footprint of healthcare is enormous.[1] Almost 10% of the United States’ greenhouse gas (GHG) emissions are contributed by healthcare.[2,3] More than a third of all hospital waste are generated during the perioperative period and surgical care. Inhaled anesthetics account for 2.5% of the GHG emissions attributed to the National Health Service of the United Kingdom.[1] In 2014...
T HE INSPIRED AIR MAY BE POLLUTED by a variety of factors ranging from personal air pollution, as cigarette smoking, to contamination of all the air in a locality as occurs in Los Angeles or the Tokyo-Yokohama area of Japan. The rapid expansion of industry, the use of synthetic chemicals and the increased use of the automobile have created many air pollution problems, so that the clean air supp...
moisture and air pollutions intensify metallic and nonmetallic surface corrosions. corroded surfaces exposed to rain washing cause pollution transportation in water and soil environment, especially in industrial areas. investigation of storm runoff quality in pars special economic energy zone (pseez) has shown heavy metals in storm basins of gas refineries and petrochemical industries.in this p...
This contribution regards three fundamental aspects of the urban pollution, sources, diffusion and chemical composition with relative speciation, pointing out the anthropogenic activities and their relationship with the environmental sustainability. The chemical parameters ruled by laws (conventional pollutants) are evidenced together with other species not ruled (no conventional pollutants) bu...
A lidar system, incorporating tunable dye lasers and a 25-cm diam Newtonian telescope, has been constructed and applied in atmospheric pollution monitoring. The system, which is fully controlled by a specially designed microcomputer, has been used in several field tests, where stack effluents as well as the ambient air have been monitored. Results from particle, NO(2), and SO(2) measurements ar...
This paper presents the tasks, procedures and instrumental trends in analytics and monitoring of air pollution. The classification of methods and analytical techniques used for atmospheric air studies are also discussed.
Production of iron through BF route is still a dominant route and coke is a major raw material and energy source for the blast furnaces. The process of coal carbonization in slot ovens is one of the major sources of atmospheric pollution in an Integrated Steel Plant. Coke making process involves coal preparation, carbonization and coke handling operations. To meet the demand of Blast Furnaces o...
