Lancet Planet Health
. 2025 Feb;
9(2):e92-e102.
PMID: 39986327
Background: The impact of past air quality improvements on health and equity at low pollution levels near the revised WHO air quality guidelines remains largely unknown. Less is known about...

Airborne ultrafine particle concentrations and brain cancer incidence in Canada's two largest cities
Lloyd M, Olaniyan T, Ganji A, Xu J, Simon L, Zhang M, et al.
Environ Int
. 2024 Oct;
193:109088.
PMID: 39467481
Background: Malignant brain tumours are rare, but are important to study because survival rates are low and few modifiable risk factors have been identified. Existing evidence suggests that outdoor ultrafine...

Environ Epidemiol
. 2024 Jul;
8(4):e317.
PMID: 39022188
Background: Outdoor fine particulate air pollution, <2.5 µm (PM) mass concentrations can be constructed through many different combinations of chemical components that have varying levels of toxicity. This poses a...

Lloyd M, Olaniyan T, Ganji A, Xu J, Venuta A, Simon L, et al.
Am J Respir Crit Care Med
. 2024 Jun;
210(11):1338-1347.
PMID: 38924496
Outdoor fine particulate air pollution (particulate matter with an aerodynamic diameter ⩽2.5 μm; PM) contributes to millions of deaths around the world each year, but much less is known about...

Geohealth
. 2023 Sep;
7(9):e2023GH000816.
PMID: 37654974
Recent studies have identified inequality in the distribution of air pollution attributable health impacts, but to our knowledge this has not been examined in Canadian cities. We evaluated the extent...

Health Rep
. 2023 Jul;
34(7):19-26.
PMID: 37470464
Background: Household air conditioning is one of the most effective approaches for reducing the health impacts of heat exposure; however, few studies have measured the prevalence of household air conditioning...

Environ Health Perspect
. 2023 Mar;
131(3):37010.
PMID: 36920446
Background: Numerous epidemiological studies have documented the adverse health impact of long-term exposure to fine particulate matter [particulate matter in aerodynamic diameter ()] on mortality even at relatively low levels....

Health Rep
. 2023 Feb;
34(2):3-16.
PMID: 36791269
Background: Mortality rates in Canada have been shown to vary by population group (e.g., Indigenous peoples, immigrants) and social economic status (e.g., income levels). Mortality patterns for some groups, including...
