Air pollution and daily hospitalization rates for cardiovascular and respiratory diseases in London, Ontario

Abstract

In this paper, we examine the role that ambient air pollution plays in exacerbating cardiovascular and respiratory disease hospitalization in London, Ontario from 1 November 1995 to 31 December 2000. The number of daily cardiac and respiratory admissions was linked to concentrations of air pollutants (sulphur dioxide, nitrogen dioxide, ozone, carbon monoxide, coefficient of haze, PM 10 ) and weather variables (maximum and minimum of temperature and humidity). Results showed that current day carbon monoxide and coefficient of haze produced significant percentage increase in daily cardiac admissions of 8.0% (95% CI: 1.5-11.5%) and 5.7% (95% CI: 0.9-10.8%) for people < 65 years old. PM 10 was found to be significantly associated with asthma admission in the > 65 group, with percentage increase in cardiac admission of 25% (95% CI: 2.8-52.3%) and 26.0% (95% CI: 5.3-50.9%) for current day and 2-day means, respectively.

Particle (Soot) Pollution in Port Harcourt Rivers State, Nigeria—Double Air Pollution Burden? Understanding and Tackling Potential Environmental Public Health Impacts

“…Correspondingly, some studies [80] indicate correlation between PM exposures with respiratory diseases in older adults. Controlled epidemiological studies of human exposures to PM 2.5 concentrated ambience among older adults indicated decreased heart rate variability (HRV) with or without accompanying COPD [81,82]. Furthermore, some epidemiological studies have shown an association of short-term PM 2.5 [83] and PM 10 [84,85] exposure among older adults ≥75 years, with the progression of health effects from early stages to cardiovascular-related hospitalization or respiratory-related hospitalization and eventual non-accidental death.…”

The impact of 9/11 on the association of ambient air pollution with daily respiratory hospital admissions in a Canada‐US border city, Windsor, Ontario

“…This work aroused great concern among the local people, public health professionals and government agencies. This in turn led to a number of other studies that examined the association between ambient air quality and health effects in Windsor [8,9]. These studies reported, among other things, short-term effects of air pollutants on daily cardiac and respiratory hospital admissions among the people in Windsor.…”

Place effects on noise annoyance: Cumulative exposures, odour annoyance and noise sensitivity as mediators of environmental context

“…Additionally, previous noise mapping of the border corridor showed that traffic along Huron Church Road, which is the main access road to the bridge crossing, has a significant impact on noise levels in the surrounding neighbourhoods (Novak et al, 2009). Effects of air pollution on health have also been observed, with increased rates of cardiac hospitalization from short-term increases in ambient concentrations, and increased levels of respiratory hospitalizations in the months following 9/11 when heightened security measures resulted in exceptionally long crossing queues in the corridor area (Fung et al, 2005;Luginaah et al, 2006a).…”
