BACKGROUND Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease that affects approximately 1% of the adult population, and to date, genetic factors explain < 50% of the risk. Particulate air pollution, especially of traffic origin, has been linked to systemic inflammation in many studies. OBJECTIVES We examined the association of distance to road, a marker of traffic pollution...

Exposures to ambient air traffic-related pollutants and their sources have been associated with respiratory and asthma morbidity in children. However, longitudinal investigation of the effects of traffic-related exposures during early childhood is limited. We examined associations of residential proximity and density of traffic and stationary sources of air pollution with wheeze, asthma, and im...

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...

BACKGROUND AND OBJECTIVE Exposure to traffic-related air pollutants is an important public health issue. Here, we present a systematic review and meta-analysis of research examining the relationship of measures of nitrogen oxides (NOx) and of various measures of traffic-related air pollution exposure with lung cancer. METHODS We conducted random-effects meta-analyses of studies examining expo...

Air pollution kills more than 5.9 million people annually, with more than 90 per cent of these deaths in capital city of India, Delhi. For improving the status of air pollution in Delhi, various policies and laws have been implemented. But even after the implementation of CNG, there was no significant change of pollutants (NOx, O3, SPM, RSPM & CO) except SO2. The objective of our study is wheth...

BACKGROUND Air pollution and weather are just two of many environmental factors contributing to traffic accidents (RTA). OBJECTIVES This study assessed the effects of these factors on traffic accidents and related mortalities in Ahvaz, Iran. METHODS In this ecological study, data about RTA, traffic-related mortalities, air pollution (including NO, CO, NO2, NOx PM10, SO2, and O3 rates) and c...

Traffic is one of the main sources of air pollution in metropolitan areas. With development of transportation system, inappropriate vehicle production, and the use of low-quality fuels, increased pollution in these areas is inevitable. The current study tries to determine PM2.5, PM10, NO2, and CO emission dispersion, caused by traffic, using CALINE4 software. Ac...

BACKGROUND Traffic-related pollution is associated with the onset of asthma in children. Its effect on adult-onset asthma is poorly investigated. The SAPALDIA cohort study was used to investigate associations between the 11-year change (1991-2002) in home outdoor traffic-related particulate matter up to 10 microm in diameter (TPM(10)) and the incidence of asthma. METHODS Never-smokers without...

BACKGROUND Several studies have found an effect on mortality of between-city contrasts in long-term exposure to air pollution. The effect of within-city contrasts is still poorly understood. OBJECTIVES We studied the association between long-term exposure to traffic-related air pollution and mortality in a Dutch cohort. METHODS We used data from an ongoing cohort study on diet and cancer wi...
