Fine Particulate Air Pollution and Adverse Birth Outcomes: Effect Modification by Regional Nonvolatile Oxidative Potential.

Background: Prenatal exposure to fine particulate matter air pollution with aerodynamic diameter ≤2.5 μm (PM) has been associated with preterm delivery and low birth weight (LBW), but few studies have examined possible effect modification by oxidative potential.

Objectives: The aim of this study was to evaluate if regional differences in the oxidative potential of PM modify the relationship between PM and adverse birth outcomes.

Biomass Burning as a Source of Ambient Fine Particulate Air Pollution and Acute Myocardial Infarction.

Background: Biomass burning is an important source of ambient fine particulate air pollution (PM2.5) in many regions of the world.

Methods: We conducted a time-stratified case-crossover study of ambient PM2.

The impact of a landfill fire on ambient air quality in the north: A case study in Iqaluit, Canada.

A large landfill fire occurred in Iqaluit, Canada in spring/summer 2014. Air quality data were collected to characterize emissions as well as potential threats to public health. Criteria pollutants were monitored (PM2.
