“…Several other studies confirm that fixed ambient air monitoring stations are poor predictors of personal exposure (e.g. Alm et al 2001; Vellopolou and Ashmore 1998). However, to gain better understanding of extended exposure situation, data collected with personal monitors for individuals with different daily routines would be desirable.…”

Spatial variations of Carbon Monoxide (CO) are examined in the urban environment of Ouagadougou, Burkina Faso. Focus is given on the variations between urban background, roadside and in-traffic measurements. Results show significant differences between the three methods where average in-traffic values were 2-3 times higher than average roadside values and 10-12 times higher than average background values. During traffic congestions these differences extended up to 6 and 20 times respectively. Results are discussed in relation to human exposure assessments and WHO guidelines.

“…The still frequent and often lethal carbon monoxide intoxications and the indoor sources and levels of carbon monoxide that cause them, however, are not related to ambient air carbon monoxide concentrations or affected by policies. (Alm et al, 2001;Braubach et al, 2013) SO 2 Indoor sources, residential coal burning, unvented paraffin lamps and heaters still dominate some exposures of some individuals to SO 2 . In current European urban environments, however, indoor sources that would significantly influence the population exposure to SO 2 are rare.…”

This document presents answers to 24 questions relevant to reviewing European policies on air pollution and to addressing health aspects of these policies. The answers were developed by a large group of scientists engaged in the WHO project "Review of evidence on health aspects of air pollution -REVIHAAP". The experts reviewed and discussed the newly accumulated scientific evidence on the adverse effects on health of air pollution, formulating science-based answers to the 24 questions. Extensive rationales for the answers, including the list of key references, are provided. The review concludes that a considerable amount of new scientific information on the adverse effects on health of particulate matter, ozone and nitrogen dioxide, observed at levels commonly present in Europe, has been published in recent years. This new evidence supports the scientific conclusions of the WHO air quality guidelines, last updated in 2005, and indicates that the effects in some cases occur at air pollution concentrations lower than those serving to establish these guidelines. It also provides scientific arguments for taking decisive actions to improve air quality and reduce the burden of disease associated with air pollution in Europe.This publication arises from the project REVIHAAP and has been co-funded by the European Union.

“…On the contrary, much weaker associations were reported between personal and outdoor concentrations (Alm et al 2001;Sørensen et al 2005). Urban background monitoring stations may give a good estimate of exposure to fine particles, given the high homogeneity of particles belonging to the accumulation mode on a regional scale, but they are not suitable to characterize exposures significantly influenced by individual point sources (Oglesby et al 2000).…”

“…In addition, the physical-chemical properties of pollutants and some micro-environmental parameters affect the spatial distribution of particles and gases in atmospheric environments, leading to a mismatch between personal levels and fixed-site concentrations. The association may also vary as a function of the sampling period, since short-time fluctuations in concentrations, which can occur in the proximity of some point source emissions, are undetectable when sampling was carried out on longer time scales (Alm et al 2001).…”

“…In general, large differences were also found between personal and ambient levels of carbon monoxide (CO) (Vellopoulou and Ashmore 1998), due again to the high spatial variability of this pollutant, especially in some outdoor environments (Dor et al 1995;Ott 1982). As a general rule, data derived from fixed monitoring stations are unable to explain adequately the personal exposure also to this pollutant (Kim et al 2006), especially in the short period (Alm et al 2001). A better representation of personal exposure can be reached with an accurate data collection of the activities over time (Georgoulis et al 2002;Vellopoulou and Ashmore 1998).…”

This study tested the reliability of a novel method developed for assessing the individual exposure to size-fractionated particulate matter (PM) and gaseous urban pollutants. Individual exposure was defined as the exposure constantly measured in proximity to the subject, even during transfers.Individual exposure was measured using a mobile monitoring unit (MMU), developed to sample simultaneously some urban pollutants of interest for public health purposes. The obtained concentrations were compared with those simultaneously collected in the breathing zone, considered as the gold standard for estimating human exposure to air pollutants.Short-time number concentrations of ultrafine, fine, and coarse particles collected by MMU were characterized by a high predictivity of personal exposures (R 2 ≥ 0.89; slope 0.94-1.17 for PM < 10 µm), far superior to fixed-site measurements. 5-h time-weighted averages fully explained the variability of ultrafine and fine particles (R 2 > 0.99).The concentrations of gaseous pollutants measured by MMU were less correlated with those collected in the breathing zone (R 2 = 0.34-0.65). Nevertheless, the capability of the MMU to detect the variations of personal exposures to O 3 and CO was better than that normally observed using fixed measurements, likely due to the placement of the MMU in the different microenvironments where subjects spent their time.Individual exposures measured by the MMU could be of importance in toxicological and epidemiological studies on PM, with the advantage of accounting for exposure to several gaseous copollutants.
