Coal-fired power plants (CFPPs) consume large amounts of coal and can potentially release this element into surrounding environment. However, knowledge of fates of Tl inside CFPPs and associated atmospheric emissions is still very limited. In this study, five CFPPs with pulverized coal boilers (PC) in Guizhou province, southwest

Computational Simulation of Incineration of Chemically and Biologically Contaminated Wastes J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-20 Paul Lemieux; Timothy Boe; Anna Tschursin; Martin Denison; Kevin Davis; Dave Swensen
ABSTRACT This paper describes the modeling approach and example results for a newly introduced computational simulation tool to evaluate waste destruction in thermal incineration systems. The Configured Fireside Simulator (CFS) is a software simulator, originally developed for the Department of Defense to evaluate operations of the chemical demilitarization incinerators processing the chemical warfare

Development, and evaluation of a mobile laboratory for collecting short-duration near-road fine and coarse ambient particle and road dust samples J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-20 Marco Martins; Joy Lawrence; Stephen Ferguson; Jack M. Wolfson; Petros Koutrakis
Abstract This study used fine and coarse PM concentrator technology in a Mobile Particle Concentrator Platform (MPCP) designed and built to allow the collection of large amounts of ambient PM, enabling time-resolved speciation analysis, which would not be feasible using conventional methods. One hour of sampling yielded sufficient sample loading for trace elemental analysis using X-Ray Fluorescence

Measurement of the gross alpha activity of the fine fractions of road dust and near-roadway ambient particle matter J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-16 Joy Lawrence; Marco Martins; Man Liu; Petros Koutrakis
ABSTRACT Traffic-related air pollution, including direct exhaust emissions and road dust (RD), impacts individuals living near busy roads. We recently conducted a study to investigate the sources and composition of tailpipe and non-tailpipe traffic emissions, where we collected and analyzed samples of ambient air fine particulate matter (PM2.5) and fine RD (RD2.5) at different distances from major

Novel Cross-Flow Electrostatic Precipitator: Numerical and Experimental Study J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-16 Ohioma Eboreime; Muhammad Ali; Khairul Alam; Alireza Sarvestani; Sean Jenson
ABSTRACT Electrostatic precipitators (ESP) are used extensively for removing particulates from a gas flow by charging the particles and then removing them in the presence of an electric field. Traditional ESP designs use the walls of the flow channel as the grounded collection surface. The objective of this present study is to evaluate a novel ESP configuration, recently patented by Ohio University’s

Evaluation of Depth-Dependent Properties of Municipal Solid Waste Using a Large Diameter-Borehole Sampling Method J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-12 John Hartwell; M. Sina Mousavi; Jongwan Eun; Shannon Bartelt-Hunt
Abstract This study is to analyze geotechnical properties and biological status of undisturbed municipal solid waste (MSW) associated with depth by using a large-diameter borehole sampling method. Through the method, a 28 m-borehole with 0.8 m of the diameter was drilled into the MSW body consisting of ten-lift layers of waste placed over 4000 days in an operating landfill. MSW sample cuttings were

Analysis on the applicability of modified polyvinyl alcohol (MPA) for temporary controlling the dust from soil in construction site. J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-12 Min Li; Hongpu Du; Lang Zhou; Shouxi Chai; Min Wang
Abstract Dust from construction field is one of sources for the atmosphere particulate pollution. In this study, a solidifying material, modified polyvinyl alcohol (MPA), is used to control the dust from soil. The controlling efficiency of MPA is evaluated based on its anti-wind and anti-rain erosion performance under different conditions (i.e., soil types, spraying amount of MPA, slope morphologies

Savings in per-passenger CO2 emissions using rail rather than air travel in the northeastern U.S. J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-05 C. Andrew Miller
Abstract Individuals and institutions seeking to reduce travel-related carbon dioxide (CO2) emissions by changing travel modes need information on the amount of CO2 that can be saved by rail travel rather than air travel. This study uses flight emissions data from the International Civil Aviation Organization (ICAO) to estimate average per-passenger CO2 emissions saved by using rail travel between

Ambient particulate matter levels and health profile in residents of Choba and Mgbuoba areas of Rivers state: a cross-sectional study J. Air Waste Manag. Assoc. (IF 2.245) Pub Date : 2020-11-04 E. O. Nwaichi; S. E. Uzodike; B. A. Amadi; E. O. Ugwoha
Abstract The study investigated the health profile of individuals exposed to particulate matter (Black) soot in Choba and Mgbuoba localities of Port Harcourt. The analysis was executed with the aid of 100 respondents (50 from Choba and 50 from Mgbuoba). A structured questionnaire with the outlined elements was utilized during data collection for the study: Manner of living, Type of occupation, Environmental
