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 ...

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.

Emission factors and emission inventory of diesel vehicles in Nepal

Science of The Total Environment, 2022
A comprehensive emission inventory of the transport sector through fuel-based emission factors (EFs) was developed for the first time in Nepal. This study estimates air pollutants emission from diesel vehicles between the years 1989 and 2018 based on national statistical data, average vehicle kilometers travelled, fuel mileage, and measurement-based ...

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 ...

Factors Influencing Diesel Emissions

SAE Technical Paper Series, 1968
<div class="htmlview paragraph">Smoke, odor, and other emissions of concern in environmental pollution from four diesel engines were studied experimentally; engine design, operational mode, and fuel characteristics were considered as variable factors influencing the emissions.

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Existing information on tailpipe emissions from the literature has been coupled with previously unpublished data to develop a summary of the effects of fuel composition on emissions.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 ...

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 ...

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

Power Plant Emission Factors

1997
NOx and heavy metal emissions from coal-fired power plants contribute significantly to total national emissions for most countries. For emission inventory purposes a methodology has been developed in order to estimate NOx emission factors for combustion installations.

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.
