Traffic, Air Pollution, and Distributional Impacts in Dar Es Salaam: A Spatial Analysis with New Satellite Data

Air pollution from vehicular traffic is a major source of health damage in urban areas. The problems of urban traffic and pollution are essentially geographic, because their incidence and impacts

A Spatial Analysis with New Satellite Data

A study to reduce atmospheric emissions of an existing natural gas dehydration plant using multiple thermodynamic models

Using Aspen Plus, operating parameters of an existing triethylene glycol natural gas dehydration plant including the solvent circulation rate, stripping gas flow rate, regenerator reboiler duty,

A Study on the Characteristics of Condensable Fine Particles in Flue Gas

The study evaluated methods to measure condensable data need to be calculated in stages by facility condition according to the CPM measurement method in the study. About 80% of PM in flue gases are

Demystifying risk attitudes and fertilizer use: A review focusing on the behavioral factors associated with agricultural nitrogen emissions in South Asia

Fertilizer use is environmentally unsustainable in South Asia. Ideally, farmers would follow optimal fertilization rates for crops based on scientific recommendations. However, there is ample

Comparison of PM2.5 Concentrations in Cities of Varying Population Size Across Mississippi, USA

The concentration of fine particulate matter (PM2.5) and the meteorological parameters were investigated at six monitoring stations across Mississippi, USA, from September 2013 to December 2014. The

Improvements in Air Quality and Health Outcomes Among California Medicaid Enrollees Due to Goods Movement Actions.

This project aimed to examine the impact of the GM policy actions on reductions in ambient air pollution and subsequent improvements in health outcomes of Medi-Cal fee-for-service beneficiaries with chronic conditions in 10 counties in California by using a difference-in-differences (DiD) model.

PM2.5 Forecasting Model Using a Combination of Deep Learning and Statistical Feature Selection

The study points out that chemical processed model of particulate matter 10 micrometers or less in diameter (PM10), Sulfur D dioxide (SO2), and Nitrogen Dioxide (NO2) have the highest accuracy or lowest Root Mean Square Error (RMSE) and more short training and testing time among the other models.

An Assessment of the Mobile Source Contribution to PM10 and PM2.5 in the United States

Mobile sources are significant contributors to ambient particulate matter (PM) in the United States. As the emphasis shifts from PM10 to PM2.5, it becomes particularly important to account for the

Detection of Excess Ammonia Emissions from In-Use Vehicles and the Implications for Fine Particle Control

The emission rate for ammonia from in-use vehicles is calculated based on measurements made inside a Los Angeles roadway tunnel. Using fleet distributions by vehicle age and type, known catalyst

Exhaust Particle Size Distribution Measurements at the Tuscarora Mountain Tunnel

On-road particle size distributions were measured at the Tuscarora Mountain tunnel on the Pennsylvania Turnpike in May 1999. The data were obtained using a scanning mobility particle sizer. The

The Contribution of Sulfate and Nitrate to Atmospheric Fine Particles During Winter Inversion Fogs in Cache Valley, Utah

Abstract Air pollutants were collected in Logan, Cache County, UT, in February 1993 during two periods of atmospheric inversion accompanied by fog. The following atmospheric species were determined:

Multicomponent remote sensing of vehicle exhaust emissions by dispersive IR and UV spectroscopy

Direct remote sensing of vehicle exhaust emissions under real-world driving conditions is desirable for a number of reasons, including: identifying high emitters, investigating the chemical

On-Road Measurement of Ammonia and Other Motor Vehicle Exhaust Emissions

Ammonia is the primary alkaline gas in the atmosphere and contributes to fine particle mass, visibility problems, and dry and wet deposition. The objective of this research was to measure ammonia and

Weekday versus Weekend Activity Patterns for Ozone Precursor Emissions in California’s South Coast Air Basin

Changes in emissions result in an increase of more than 30% in the ROG/NOx ratio on weekends compared with weekdays, which, along with lower NOx emissions, leads to increased O3 production on weekends.
