Woodstove emission measurement methods: Comparison and emission factors update

Environmental Monitoring and Assessment, 1993
On February 26, 1988, the U.S. Environmental Protection Agency promulgated Standards of Performance for residential wood heaters, or woodstoves. Over the past several years, a number of field studies have been undertaken to determine the actual level of emission reduction achieved by new technology woodstoves in everyday use.

Health effects of soy-biodiesel emissions: mutagenicity-emission factors

Inhalation Toxicology, 2015
Soy biodiesel is the predominant biodiesel fuel used in the USA, but only a few, frequently conflicting studies have examined the potential health effects of its emissions.We combusted petroleum diesel (B0) and fuels with increasing percentages of soy methyl esters (B20, B50 and B100) and determined the mutagenicity-emission factors expressed as ...

Fuel Factors in Automotive Tailpipe Emissions

American Industrial Hygiene Association Journal, 1971
Existing information on tailpipe emissions from the literature has been coupled with previously unpublished data to develop a summary of the effects of fuel composition on emissions. Where data are lacking, effects have been predicted. For fuels of present hydrocarbon composition but without lead antiknocks, there may be some increases in emissions of ...

Spatial Applicability of Emission Factors for Modeling Mobile Emissions

Environmental Science & Technology, 2002
Driving cycles are used to create mobile emission factors. Emission factors are, in turn, used to estimate mobile source inventories, provide standards for new vehicle emissions testing, and facilitate comparisons of laboratory experiments. This study examines the spatial representativeness of the driving cycles underlying California's CO, THC, and NOx

Development of Emission Factors for Polypropylene Processing

Journal of the Air & Waste Management Association, 1999
Emission factors for selected volatile organic compounds and particulate emissions were developed during extrusion of commercial grades of propylene homopolymers and copolymers with ethylene. A small commercial extruder was used. Polymer melt temperatures ranged from 400 to 605 °F.

Improvement of emission factors

2004
In the following Sections, measurements conducted to improve and validate emission factors as well as modelling work are described. The aim of this work was to lead to an improvement of emission factors and thus to an overall improvement of the accuracy of emission data and to quantify and reduce uncertainties.

Fluoride emission factors

2019
An attempt was made to generate fluoride emission factor data for a fast- and single-fired ceramic floor-tile kiln located in Turkey. Desired emission factors were calculated from stack-gas measurements and mass-balance determinations. Suitably sampled stack-gas emissions as well as unfired and fired ceramic products were pretreated, isolated and then ...

Emission Factors for Trichloroethylene Vapor Degreasers

AIHAJ, 1989
Emission factors were developed for two production trichloroethylene (TCE) vapor degreasers: an open-top (0.76 m x 1.16 m x 1.8 m) and a conveyor-fed enclosed design. Both were fitted with functioning local exhaust hoods. Emissions were determined from field data by using a Fick's law diffusion approach and the observed variation in time of the TCE ...

Fine structure and the emission filling factor

Space Science Reviews, 1994
There is observational evidence for an extreme fine structure in the solar transition region, much smaller than 1″ in size (Dereet al., 1987, 1988) Corresponding to this extreme fine structure there appear to be an equally complex dynamical structure.

Anthropogenic mercury emission inventory with emission factors and total emission in Korea

Atmospheric Environment, 2010
Abstract Mercury emissions concentrations, emission factors, and the total national emission from major anthropogenic sources in Korea for the year 2007 were estimated. Uncontrolled and controlled mercury emission factors and the total emission from each source types are presented. The annual national mercury emission from major anthropogenic sources
