We produce evidence reviews based on our assessments of needs and gaps in evidence-based environmental health practice and policy. We also work with researchers and environmental public health students for reviews. These documents are peer-reviewed and the content is the responsibility of the authors.
Population level wildfire smoke exposure is complex. It is difficult to measure and prevent. Reducing the adverse physical and mental health effects related to smoke exposure requires insight into social, economic, political and health-related factors within communities. In an attempt to understand some of the challenges of planning for wildfire smoke events, this report outlines the findings...

The period between conception and early childhood when vital organs are forming and rapidly developing is the most vulnerable of life stages to the effects of toxic environment exposures, including traffic-related air pollution (TRAP). Epidemiologic studies on preterm birth have consistently shown elevated risks with a number of measures of...

Reducing cardiovascular health impacts from traffic-related noise and air pollution: intervention strategies
Recent studies suggest that exposure to both traffic-related air pollution (TrAP) and to road traffic noise (RTN) are independent risk factors for cardiovascular disease (CVD). While the exact pathophysiologic mechanisms are not known, plausible biological models exist for both associations. This paper describes interventions and mitigating measures aimed at reducing both air and noise pollution...View Full Article
Cardiovascular Health, Traffic-related Air Pollution and Noise: Are associations mutually confounded? A systematic review
This review assessed the confounding effect of one traffic-related exposure (noise or air pollutants) on the association between the other exposure and cardiovascular outcomes. A systematic review was conducted with the databases Medline and Embase. The confounding effects in studies were assessed by using change in the estimate with a 10 % cutoff point. The influence on the change in the...View Full Article
Forest residues are non-merchantable woody biomass found in forests and wood waste from logging practices and industrial operations, such as sawmills. Forest residues are a convenient fuel for open-burning and conventional biomass burning systems (e.g., fireplaces and wood stoves), but more recently have been considered as a fuel for advanced wood combustion (AWC) integrated energy systems, used...

Nearly 200 million tonnes of livestock manure are generated in Canada each year.1 Manure storage and land application tends to produce odour, greenhouse gases, microbes, and particulate matter, which can negatively impact the environment and human health. Occupational exposures of manure management have been linked to psychological stress and adverse effects on the respiratory system and heart...View Full Article
Nanotechnology is the creation of materials, devices, and systems by controlling matter at the nanometer scale (1-100 billionths of a meter). Potential exposures to engineered nanoparticles (ENPs) through contact with consumer products or air, water, and food sources are an emerging potential threat to human health. ENPs have unique properties and characteristics in addition to size, such as a...View Full Article
Air cleaners are designed to remove pollutants from indoor air, but their effectiveness depends on the air cleaner design and set-up, as well as on the presence of specific pollutants, their concentrations, and air exchange rates in the room/home. Ozone generators and some electrostatic precipitators produce ozone at levels that pose health concerns. Little evidence is available on removal of...View Full Article
A significant portion of children’s exposure to traffic-related pollution occurs in and around schools and daycares and in transit to these locations. New schools and daycare facilities should be located at least 150 m from major roads (15,000 or more vehicles/day) and should incorporate appropriate ventilation systems to reduce infiltration of outdoor pollutants. Interventions for existing...View Full Article

While the effects of daily fine particulate exposure (PM) have been well reviewed, the epidemiological and physiological evidence of cardiovascular effects associated to sub-daily exposures has not. We performed a theoretical model-driven systematic non-meta-analytical literature review to document the association between PM sub-daily exposures (≤6 hours) and arrhythmia, ischemia and...View Full Article
Active transportation refers mainly to walking and cycling for transportation.Health Benefits: People who use active transportation are, on average, more physically fit, less obese, and have a reduced risk of cardiovascular disease compared to people who use only motorized transportation.A shift from motorized transportation to active transportation has the potential for societal benefits...View Full Article
This report summarizes information on woodsmoke emissions and health effects associated with woodsmoke exposures from residential wood-burning (RWB) in Canada and provides a qualitative indication of the potential effectiveness of different intervention strategies based on a review of the available literature and interviews with Canadian health authorities. The purpose of this...View Full Article
Based on appraisals of recent systematic reviews and patient information, this report provides an overview of: 1) evidence available to generate health protection measures; 2) health protection advice currently recommended to persons with/at risk of cardio-vascular diseases through public health, medical, patient information, environmental, and meteorological websites; and 3) a general framework...View Full Article
