Urban air quality stands as a pressing concern in cities globally, with airborne particulate matter (PM) emerging as a significant threat to human health. Trees possess a diverse array of characteristics that can effectively mitigate urban air pollution, and cities around the wor...

Aim:  We conducted a systematic review/meta-analysis for epidemiologic evidence of the association between long-term criteria air pollution (nitrogen dioxide (NO2), sulfur dioxide (SO2), coarse particulate matter (PM10), fine particulate matter (PM2.5), ozone (O3), carbon mo...

Background The COVID-19 pandemic was caused by the SARS-CoV-2 coronaviruses transmitted mainly through exposure to airborne respiratory droplets and aerosols carrying the virus. Objective To assess the transport and dispersion of respiratory aerosols containing the SARS-CoV-2 vir...

Inhalation exposure to plastic incineration emissions (PIEs) is a problem of increasing human relevance, as plastic production and waste creation have drastically increased since mainstream integration during the 20th century. We investigated the effects of PIEs on human nasal ep...

A growing body of evidence indicates that exposure to air pollution affects cognitive performance; however, few studies have assessed this in the context of repeated measures within a large group of individuals or in a population with a large age range. In this study, we evaluate...

Objective: Short-term ambient fine particulate matter (PM2.5) is associated with adverse cardiovascular events including myocardial infarction (MI). However, few studies have examined associations between PM2.5 and subclinical cardiomyocyte damage outside of overt cardi...

Wildfires adversely impact air quality and public health worldwide. Exposures to wildfire smoke are linked to adverse health outcomes, including cardiopulmonary diseases. Critical research gaps remain surrounding the underlying biological pathways leading to wildfire-induced heal...

Background: Environmental epidemiologists strive to conduct research that will lead to actions that improve public health outcomes. The risk assessment process is the bridge between scientific research and policies that can impact public health. Historically, epidemiologic studie...

Background: Preterm birth (PTB; <37 weeks completed gestation) is associated with exposure to air pollution, though variability in association magnitude and direction across exposure windows exists. We evaluated associations between weekly gestational exposure to fine par...

Epidemiologic studies of ambient fine particulate matter (PM2.5) and ozone (O3) often use outdoor concentrations from central-site monitors or air quality model estimates as exposure surrogates, which can result in exposure errors. We previously developed an exposure model called...

Background. Air pollution is a prominent contributor to the burden of adverse birth and early child health outcomes. However, considerable heterogeneity of impacts has been observed, which may be due to limited exploration of key effect modifiers. This scoping review was conducte...

             Intracellular redox homeostasis is closely regulated through adaptive signaling and metabolic pathways. However, environmental exposure to xenobiotic stressors such as secondary organic aerosols (SOA) can alter intracellular redox h...

Social cohesion can reduce stress, increase social interaction, and improve cognitive reserve. These social mechanisms may modify the effects of air pollution on dementia risk. This cohort study examines the potential moderating effect of social cohesion on associations between j...

Per- and polyfluoroalkyl substances (PFAS) have garnered increasing attention in recent years and non-targeted analysis (NTA) has become essential for elucidating novel PFAS structures. NTA and PFAS research have been dominated by liquid chromatography  - mass spectrometry (LC-MS...

Air pollution is a significant environmental health risk for urban areas and developing countries. Air pollution may contribute to the incidence of cardiopulmonary and metabolic diseases. Evidence also points to the role of air pollution in worsening or developing neurological an...

Epidemiological evidence suggests the potential for air pollutants to induce male reproductive toxicity. Of these studies, exposure to the oxidant air pollutant, ozone, during sensitive windows in the sperm lifecycle has been associated with impaired sperm motility. Based on thes...

Wildland fres contribute signifcantly to the ambient air pollution burden worldwide, causing a range of adverse health efects in exposed populations. The toxicity of woodsmoke, a complex mixture of gases, volatile organic compounds, and particulate matter, is commonly studied in ...

Exposure to ambient fine particulate matter (PM2.5) was found to produce vascular injury, possibly by activating platelets within days after exposure. The aim of this study was to investigate the modulatory effects of dietary saturated fatty acids on platelet mitochondrial respir...

Rationale & Objectives: Wildfire smoke is associated with short-term respiratory outcomes including asthma exacerbation in children. As investigations into developmental exposure to wildfire smoke exposure (WSE) on children’s longer-term respiratory health are sparse, w...

Wildfire smoke risks are not uniformly distributed across people and places, and the most vulnerable communities are often disproportionately impacted. This study develops a Community Health Vulnerability Index (CHVI) using three major vulnerability components: adaptive capacity,...

Fine particle pollution is a well-established risk to human health. Observational epidemiology generally treats events as though they are independent of one another and so do not examine the role air pollution may play in promoting the progression of disease. Multistate survival ...

In response to increasing wildfire risks, California plans to expand the use of prescribed fire. We characterized the anticipated change in health impacts from exposure to smoke under a future fire-management scenario relative to a historical period (2008–2016). Using dispe...

Formaldehyde (HCHO) is an important air pollutant with direct cancer risk and ozone-forming potential. HCHO sources are complex because HCHO is both directly emitted and produced from oxidation of most gas-phase reactive organic carbon. We update the secondary production of HCHO ...

Subsurface contamination can migrate upward into overlying buildings, exposing the buildings’ inhabitants to contaminants that can cause detrimental health effects. This phenomenon is known as vapor intrusion (VI). When evaluating a building for VI, one must understand that...

Adrenergic receptors (AR) are manipulated therapeutically for the treatment of pulmonary and cardiovascular diseases; however, their role in air pollutant-induced respiratory effects is poorly understood. We examined the contribution of AR-subtypes in acrolein-induced respiratory...
