Few studies have investigated the chronic obstructive pulmonary disease (COPD) mortality fraction attributable to air pollution and modification by individual characteristics of air pollution effects. We applied distributed lag non-linear models to assess the associations between air pollution and COPD mortality in 2007-2011 in Guangzhou, China, and the total COPD mortality fraction attributabl...

This study aimed to investigate the association between daily air pollution levels and the occurrence of acute respiratory signs and symptoms among people with asthma or asthma-like problems. Thirty eight subjects in the southern Swedish city of Landskrona kept a daily diary for 10 weeks. The daily prevalence of symptoms, supplementary bronchodilator use and peak flow deviations were compared w...

Ultrasensitive gas sensor based on epitaxial graphene on SiC has been fabricated. The sensor exhibits strong and reproducible response to nitrogen dioxide (NO2) in the concentration in air down to 1 part-per billion (ppb). Prototype of the transportable device for environmental monitoring allows fast and reproducible measurements of NO2 concentration in the range typical for environmental pollu...

London’s air quality is the worst in the UK. Levels of pollution cause serious health impacts, which have led to UK and EU air quality targets. A considerable proportion of London will not meet these targets, particularly for nitrogen dioxide (NO2) and particulate matter (PM10). To achieve the air quality targets, significant additional action is needed, particularly to reduce road transport em...

BACKGROUND Health impacts of poor environmental quality have been identified in studies around the world and in Canada. While many of the studies have identified associations between air pollution and mortality or morbidity, few have focused on the role of health care as a potential moderator of impacts. This study assessed the determinants of health care access and utilization in the context o...
