Available in PDF, EPUB and Kindle. Book excerpt: This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.

This book was released on 2012-12-06 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: D. VAN VELZEN Commission of the European Communities, Joint Research Centre Ispra, Environment Institute, 1-21020 Ispra (Varese) ITAL Y 1. Introduction Worldwide, there is an ever increasing interest and concern about the destructive effects of air pollution on man's ecosystem. The growing awareness of these effects has revealed the need to take adequate measures to minimize the emission of air polluting products. The two most important contaminants, occurring in the largest concentrations and quantities, are sulphur dioxide and nitrogen oxides. Both pollutants are formed mainly during the combustion of fossil fuels, particularly by power stations and traffic. The effects of air pollution caused by these two contaminants have already been studied for several decades and measures to protect the environment against their adverse effects are now operative in many countries. The present volume contains the proceedings of a Eurocourse held in Ispra in September 1990. The course was meant to give an overview of present knowledge concerning the emission sources and quantities, to cover features of present legislation and to give a survey of the most important modern abatement techniques for S02 and NOx. It was mainly addressed to higher and medium management in the power, chemical and similar industries, particularly from those countries where the fight against air pollution is still in its infancy. Obviously, it was not possible to cover completely the whole range of subjects during the limited duration of a Eurocourse.

Download or read book NOx Emission Control Technologies in Stationary and Automotive Internal Combustion Engines written by B. Ashok and published by Elsevier. This book was released on 2021-11-09 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: NOx Emission Control Technologies in Stationary and Automotive Internal Combustion Engines: Approaches Toward NOx Free Automobiles presents the fundamental theory of emission formation, particularly the oxides of nitrogen (NOx) and its chemical reactions and control techniques. The book provides a simplified framework for technical literature on NOx reduction strategies in IC engines, highlighting thermodynamics, combustion science, automotive emissions and environmental pollution control. Sections cover the toxicity and roots of emissions for both SI and CI engines and the formation of various emissions such as CO, SO2, HC, NOx, soot, and PM from internal combustion engines, along with various methods of NOx formation. Topics cover the combustion process, engine design parameters, and the application of exhaust gas recirculation for NOx reduction, making this book ideal for researchers and students in automotive, mechanical, mechatronics and chemical engineering students working in the field of emission control techniques. Covers advanced and recent technologies and emerging new trends in NOx reduction for emission control Highlights the effects of exhaust gas recirculation (EGR) on engine performance parameters Discusses emission norms such as EURO VI and Bharat stage VI in reducing global air pollution due to engine emissions

Program (CCTDP) is an effort to demonstrate a new generation of innovative coal utilization processes in a series of facilities built across the country. These projects are carried out on a commercial scale to prove technical feasibility and provide the info. required for future applications. Projects have demonstrated technical options with the potential to meet the needs of energy markets while satisfying environ. requirements. Part of this program is the demo. of technologies designed to reduce emissions of oxides of nitrogen (NOx) from existing coal-fired utility boilers.

Download or read book Chemical Removal of Nitrogen Oxides from the Atmosphere written by Paul Romer and published by . This book was released on 2018 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concentration of nitrogen oxides (NOx ≡ NO + NO2) regulates the concentrations of all major atmospheric oxidants and the formation of secondary air pollutants, with consequences for climate, human health, and ecosystems. The chemical cycling between NOx and its oxidation products controls the concentration and transport of NOx and affects the spatial extent of air pollution. Previous studies have shown that permanent loss of NOx occurs both through production of HNO3 and through production of alkyl and multifunctional nitrates (RONO2). Despite their importance to atmospheric chemistry, significant uncertainties remain in the relative importance of these pathways and in the fates of RONO2 and HNO3 in the atmosphere. I use observations from two intensive field studies, the Southern Oxidant and Aerosol Study (SOAS) in Centreville Alabama and the Korea-United States Air Quality Study (KORUS-AQ) over South Korea, to provide new constraints on the lifetimes and fates of NOx oxidation products. I show that RONO2 compounds produced from isoprene oxidation have a lifetime under three hours and are lost both by gas-phase chemistry to re-release NOx to the atmosphere and by aerosol-phase hydrolysis to form HNO3. In contrast, observations of HNO3 and NOx over the Yellow Sea between China and South Korea confirm that HNO3 is nearly chemically inert in the troposphere. This finding contradicts recent proposals that HNO3 undergoes photolysis extremely rapidly in the aerosol phase. I apply these findings to investigate how the chemistry of NOx oxidation products affects the lifetime of NOx and the production of O3 in different environments. I show that, in general, the formation of short-lived NOx reservoirs extends the lifetime of NOx by sequestering NOx in less reactive forms. Furthermore, I show that in areas where the formation of RONO2 is the dominant pathway for NOx loss, ozone production efficiency no longer increases with temperature, changing the response of air quality to meteorology. Finally, I show that over the past decade, NOx chemistry has shifted in the United States towards a regime where RONO2 chemistry plays a greater role in the loss of NOx.
