Exposure to Traffic-Related Air Pollution and Perinatal Health (UBC Bridge Program)

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 TRAP, including distance of residence from traffic...

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...

Introduction to air quality advisories

Air quality advisories are a mechanism by which provincial and regional governments actively provide the public with information on hourly or daily periods of poor outdoor air quality. Advisories are issued for specific geographical locations when one or more pollutants approach or exceed (or are forecasted to approach/exceed) a relevant air quality trigger. Advisories inform the public about...

Odour from a Compost Facility

Primary inquiry: A citizen’s group reported that putrid smells were occurring daily from a local commercial compost facility located in a suburban area of the city. The local public health agency was contacted to provide information to answer the following questions: What types of contaminants are potentially emitted in air from commercial composting facilities? What causes odours associated with...

Case Study of a Persistent Landfill Fire and Community Health Impacts

This case study explores the issue of health impacts in the community from persistent landfill fires and covers a number of topics including: outdoor air pollution; waste management; health equity; health surveillance; environmental surveillance; and occupational health. Although written from a broad public health and medical health officers’ point of view, this case study may be helpful to other...

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...

Forest Residues to Energy: Is this a pathway towards healthier communities? (UBC Bridge Program)

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...

Air Quality Assessment Tools: A Guide for Public Health Practitioners

Several tools exist to assess local air quality, including the impact of specific sources, emissions, and meteorological conditions. Information generated from the use of air quality assessment tools can inform decisions on permitting of emissions, industrial siting, and land use; all can impact local air quality, which in turn can influence air pollution related health effects of a population....

Air Quality and Community Health Impact of Animal Manure Management (UBC Bridge Program)

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...

Nanotechnology: A Review of Exposure, Health Risks and Recent Regulatory Developments

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...

Minimizing Children’s Non-residential Exposure to Traffic-related Pollution (UBC Bridge Program)

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...

Residential Air Cleaner Use to Improve Indoor Air Quality and Health: A Review of the Evidence

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...

Active Transportation in Urban Areas: Exploring Health Benefits and Risks (UBC Bridge Program)

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 such...

Cardiovascular Effects of Sub-daily Levels of Ambient Fine Particles

Topics: Air, Outdoor Air 

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 myocardial...
