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.

“…Airborne mineral dust, which accounts for a large fraction of the global aerosol burden (Cakmur et al, 2006), influences climate by direct radiative perturbation (Tegen and Lacis, 1996;Balkanski et al, 2007;Nousiainen et al, 2009), affecting cloud properties (Rosenfeld et al, 2001;DeMott, 2003) and atmospheric chemistry (Usher et al, 2003). In addition, mineral dust provides the land and ocean with nutrients (Duce and Tindale, 1991;Jickells and Spokes, 2001), causes damage to human health through the inhalation of fine particulate matter (Prospero et al, 2008;Samoli et al, 2011;Prospero and Mayol-Bracero, 2013) and causes disruption to transport and economy with intense episodes of reduced visibility (Prospero, 1999;Goudie and Middleton, 2006). Ambient measurements of mineral dust composition are important for validation of global dust cycle models and their incorporation into atmospheric models (Claquin et al, 1999;Nickovic et al, 2012;Perlwitz et al, 2015).…”

Abstract. Mineralogy of silicate mineral dust has a strong influence on climate and ecosystems due to variation in physiochemical properties that result from differences in composition and crystal structure (mineral phase). Traditional offline methods of analysing mineral phase are labour intensive and the temporal resolution of the data is much longer than many atmospheric processes. Single-particle mass spectrometry (SPMS) is an established technique for the online size-resolved measurement of particle composition by laser desorption ionisation (LDI) followed by time-of-flight mass spectrometry (TOF-MS). Although non-quantitative, the technique is able to identify the presence of silicate minerals in airborne dust particles from markers of alkali metals and silicate molecular ions in the mass spectra. However, the differentiation of mineral phase in silicate particles by traditional mass spectral peak area measurements is not possible. This is because instrument function and matrix effects in the ionisation process result in variations in instrument response that are greater than the differences in composition between common mineral phases.In this study, we introduce a novel technique that enables the differentiation of mineral phase in silicate mineral particles by ion formation mechanism measured from subtle changes in ion arrival times at the TOF-MS detector. Using a combination of peak area and peak centroid measurements, we show that the arrangement of the interstitial alkali metals in the crystal structure, an important property in silicate mineralogy, influences the ion arrival times of elemental and molecular ion species in the negative ion mass spectra. A classification scheme is presented that allowed for the differentiation of illite-smectite, kaolinite and feldspar minerals on a single-particle basis. Online analysis of mineral dust aerosol generated from clay mineral standards produced mineral fractions that are in agreement with bulk measurements reported by traditional XRD (X-ray diffraction) analysis.

“…These trends are not necessarily present, but they occur often enough that they should be checked (Samoli et al, 2011;Schwartz et al, 1996). For example, on weekends the number of hospital admissions can be lower than on weekdays and can also be lower during holidays.…”
