Chronic exposure to traffic-related air pollution (TRAP) may contribute to premature mortality, but few studies to date have addressed this topic. This study assessed the association between TRAP and mortality in Toronto, Ontario, Canada.
Asia's increasing population and economic growth has meant that the energy demand is doubling every 10 years, which is more than twice the world average, resulting in an increased risk of human exposure to higher air pollution from fossil fuel burning. In
Poverty is a major determinant of population health, but little is known about its role in modifying air pollution effects. The researchers set out to examine whether people residing in socially deprived communities are at higher mortality risk from ambient air pollution.
Various factors can modify the health effects of outdoor air pollution. Prior findings about modifiers are inconsistent, and most of these studies were conducted in developed countries. The researchers conducted a time-series analysis to examine the modifying effect of season, sex, age, and education on the association between outdoor air pollutants [particulate matter
To assess the relationship between individual-based exposure to traffic-related air pollutants and allergic disease outcomes in a prospective birth cohort study during the first 6 years of life.
Hydroxyl radicals are often called the "detergent" of the atmosphere because they control the atmosphere's capacity to cleanse itself of pollutants. In this article the researchers show that the reaction of electronically excited nitrogen dioxide with water can be an important source of tropospheric hydroxyl radicals.
Anthropogenic addition of bioavailable nitrogen to the biosphere is increasing and terrestrial ecosystems are becoming increasingly nitrogen-saturated, causing more bioavailable nitrogen to enter grou
