Assessing particulate matter emissions from future electric mobility and potential risk for human health in Canadian metropolitan area

Weeberb J. Requia, Altaf Arain, Petros Koutrakis, Ron Dalumpines

Air Quality, Atmosphere & Health > 2018 > 11 > 9 > 1009-1019

The environmental benefits from electric cars (ECs) depend on several aspects, including source of electric energy generation, type of EC, and associated air pollutant emissions. For example, EC fleet (full ECs, no hybrid ECs) do not emit gaseous pollutants, but still emit a certain amount of particulate matter. Full ECs emit particulate matter through their non-exhaust sources, which includes wear...

Weeberb J. Requia, Christopher D. Higgins, Matthew D. Adams, Moataz Mohamed, more

Environment International > 2018 > 111 > C > 164-176

Little work has accounted for congestion, using data that reflects driving patterns, traffic volume, and speed, to examine the association between traffic emissions and human health. In this study, we performed a health risk assessment of PM_2.5 emissions during congestion periods in the Greater Toronto and Hamilton Area (GTHA), Canada. Specifically, we used a micro-level approach that combines the...

Acute effects of fine particulate matter constituents on mortality: A systematic review and meta-regression analysis

Souzana Achilleos, Marianthi-Anna Kioumourtzoglou, Chih-Da Wu, Joel D. Schwartz, more

Environment International > 2017 > 109 > C > 89-100

The link between PM_2.5 exposure and adverse health outcomes is well documented from studies across the world. However, the reported effect estimates vary across studies, locations and constituents. We aimed to conduct a meta-analysis on associations between short-term exposure to PM_2.5 constituents and mortality using city-specific estimates, and explore factors that may explain some of the observed...

Spatio-temporal analysis of particulate matter intake fractions for vehicular emissions: Hourly variation by micro-environments in the Greater Toronto and Hamilton Area, Canada

Weeberb J. Requia, Matthew D. Adams, Altaf Arain, Petros Koutrakis, more

Science of The Total Environment > 2017 > 599-600 > C > 1813-1822

Previous investigations have reported intake fraction (iF) for different environments, which include ambient concentrations (outdoor exposure) and microenvironments (indoor exposure). However, little is known about iF variations due to space-time factors, especially in microenvironments. In this paper, we performed a spatio-temporal analysis of particulate matter (PM_2.5) intake fractions for vehicular...

Spatial and temporal determinants of A-weighted and frequency specific sound levels—An elastic net approach

Erica D. Walker, Jaime E. Hart, Petros Koutrakis, Jennifer M. Cavallari, more

Environmental Research > 2017 > 159 > C > 491-499

Urban sound levels are a ubiquitous environmental stressor and have been shown to be associated with a wide variety of health outcomes. While much is known about the predictors of A-weighted sound pressure levels in the urban environment, far less is known about other frequencies.To develop a series of spatial-temporal sound models to predict A-weighted sound pressure levels, low, mid, and high frequency...

Fine particulate matter and cardiovascular disease: Comparison of assessment methods for long-term exposure

Laura A. McGuinn, Cavin Ward-Caviness, Lucas M. Neas, Alexandra Schneider, more

Environmental Research > 2017 > 159 > C > 16-23

Adverse cardiovascular events have been linked with PM_2.5 exposure obtained primarily from air quality monitors, which rarely co-locate with participant residences. Modeled PM_2.5 predictions at finer resolution may more accurately predict residential exposure; however few studies have compared results across different exposure assessment methods.We utilized a cohort of 5679 patients who had undergone...

Yara Abu Awad, Petros Koutrakis, Brent A. Coull, Joel Schwartz

Environmental Research > 2017 > 159 > C > 427-434

Fine ambient particulate matter has been widely associated with multiple health effects. Mitigation hinges on understanding which sources are contributing to its toxicity. Black Carbon (BC), an indicator of particles generated from traffic sources, has been associated with a number of health effects however due to its high spatial variability, its concentration is difficult to estimate. We previously...

Weeberb J. Requia, Matthew D. Adams, Altaf Arain, Petros Koutrakis, more

Renewable and Sustainable Energy Reviews > 2017 > 78 > C > 1390-1396

Plug-in hybrid electric vehicles (PHEVs) have the potential to decrease greenhouse gas emissions given certain power generation profiles. The adoption of PHEVs is associated with significant social, economic, environmental, and health benefits. However, most researchers in literature generally estimate emissions using national averages of emission data. The purpose of this paper is to address this...

Wanda Phipatanakul, Petros Koutrakis, Brent A. Coull, Choong-Min Kang, more

Contemporary Clinical Trials > 2017 > 60 > C > 14-23

Asthma is the most common chronic disease of childhood in the United States, causes significant morbidity, particularly in the inner-city, and accounts for billions of dollars in health care utilization. Home environments are established sources of exposure that exacerbate symptoms and home-based interventions are effective. However, elementary school children spend 7 to 12h a day in school, primarily...

Lisa B. Rokoff, Petros Koutrakis, Eric Garshick, Margaret R. Karagas, more

Current Problems in Pediatric and Adolescent Health Care > 2017 > 47 > 6 > 123-141

Use of wood for residential heating is regaining popularity in developed countries. Currently, over 11 million US homes are heated with a wood stove. Although wood stoves reduce heating costs, wood smoke may adversely impact child health through the emission of gaseous and particulate air pollutants. Our purpose is to raise awareness of this environmental health issue among pediatricians.To summarize...
