Particulate matter air pollution may offset ozone damage to global crop production

Ultrafine particulate matter and high-level benzene urban air pollution in relation to oxidative DNA damage.

Air pollution, containing high-level of ultrafine particles (UFP) and benzene, is a prominent environmental health problem in many cities of the World. We investigated the level of oxidative DNA damage in mononuclear blood cells (MNBC) by the comet assay as DNA strand breaks (SB) and formamidopyrimidine DNA glycosylase (FPG) sensitive sites in residents from three urban locations in Cotonou, Be...

Transboundary Pollution: Ozone and Fine Particulate Matter in the Northeast

AHA Scientific Statement Particulate Matter Air Pollution and Cardiovascular Disease

In 2004, the first American Heart Association scientific statement on “Air Pollution and Cardiovascular Disease” concluded that exposure to particulate matter (PM) air pollution contributes to cardiovascular morbidity and mortality. In the interim, numerous studies have expanded our understanding of this association and further elucidated the physiological and molecular mechanisms involved. The...

Assessment of Indoor-Outdoor Particulate Matter Air Pollution: A Review

Background: Air pollution is a major global environmental risk factor. Since people spend most of their time indoors, the sole measure of outdoor concentrations is not sufficient to assess total exposure to air pollution. Therefore, the arising interest by the international community to indoor-outdoor relationships has led to the development of various techniques for the study of emission and e...

Cardiovascular remodeling in response to long-term exposure to fine particulate matter air pollution.

BACKGROUND Air pollution is a pervasive environmental health hazard that occurs over a lifetime of exposure in individuals from many industrialized societies. However, studies have focused primarily on exposure durations that correspond to only a portion of the lifespan. We therefore tested the hypothesis that exposure over a considerable portion of the lifespan would induce maladaptive cardiov...
