“…In the investigation carried out by Salma et al (2005), higher median PM 10 and PM 2.0 values (50 and 20 µg m -3 , respectively) were found between April and May 2002 at a kerbside compared to our median concentrations monitored during the non-heating season (15.5 and 10.2 µg m -3 for PM 10 and PM 2.5 , respectively). Ramgolam et al (2008) found in Paris PM 10 concentration values typically observed at European urban background sites.…”

To investigate the ambient mass concentration, size-distribution and temporal variability of atmospheric particulate matter (PM), a long-term monitoring campaign was undertaken at an urban background site in Como, Northern Italy, from May 2015 to March 2016. A 13-stage Low Pressure Impactor (DLPI) was used for the collection of size-segregated particulates in the 0.028-10 µm size range. The results revealed a good level of agreement between DLPI and a co-located Harvard-type PM 2.5 Impactor, allowing them to be classified as comparable and characterized by a reciprocal predictability. The PM concentration levels varied greatly between the different 5-days monitoring sessions, with higher mean mass concentrations during the heating season. Appreciable seasonal differences were found for particles between 0.15 and 1.60 µm that, on average, registered concentration levels 3.5 times higher during the heating season (mean: 28.2 µg m -3 ; median: 24.4 µg m -3 ) compared to the non-heating season (mean: 8.3 µg m -3 ; median: 7.6 µg m -3 ). No relevant and significant differences were detected for the coarser ranges (> 1.60 µm). Temporal variabilities were influenced by typical PM urban sources (e.g., household heating, traffic), that significantly affected fine and submicrometer particles, and were related to meteorological factors. Ambient air particles exhibited a trimodal distribution: a first and sharp peak more pronounced during the heating season was identified between 0.3 and 0.5 µm and two other slight peaks in the coarse mode were centered on approximately 3 and 8 µm. No relevant differences were found in the shape of the size-distribution between the two investigated seasons. The mean PM 2.5 (22.4 µg m -3 ) and PM 10 (27.7 µg m -3 ) concentrations monitored in the study area exceeded the annual Air Quality Guideline Values (respectively equal to 10 µg m -3 and 20 µg m ) established by the World Health Organization.

“…A recent study (Aphekom, 2011) reported that a reduction of PM 2.5 concentrations in Paris (average 2004Paris (average -2006.4 µg m −3 ; Airparif, 2012) towards the World Health Organization recommendation value (10 µg m −3 ) would lead to a gain in life expectancy of 5.8 months for persons 30 years of age and older. In addition, epidemiologists and toxicologists suggest investigating chemical and physical characteristics of particles in order to better assess their toxicity (Schlesinger, 2007;Ramgolam et al, 2008).…”

A one-year comprehensive chemical characterisation of fine aerosol (PM<sub>2.5</sub>) at urban, suburban and rural background sites in the region of Paris (France)

Abstract. Studies describing the chemical composition of fine aerosol (PM2.5) in urban areas are often conducted for a few weeks only and at one sole site, giving thus a narrow view of their temporal and spatial characteristics. This paper presents a one-year (11 September 2009–10 September 2010) survey of the daily chemical composition of PM2.5 in the region of Paris, which is the second most populated "Larger Urban Zone" in Europe. Five sampling sites representative of suburban (SUB), urban (URB), northeast (NER), northwest (NWR) and south (SOR) rural backgrounds were implemented. The major chemical components of PM2.5 were determined including elemental carbon (EC), organic carbon (OC), and the major ions. OC was converted to organic matter (OM) using the chemical mass closure methodology, which leads to conversion factors of 1.95 for the SUB and URB sites, and 2.05 for the three rural ones. On average, gravimetrically determined PM2.5 annual mass concentrations are 15.2, 14.8, 12.6, 11.7 and 10.8 μg m−3 for SUB, URB, NER, NWR and SOR sites, respectively. The chemical composition of fine aerosol is very homogeneous at the five sites and is composed of OM (38–47%), nitrate (17–22%), non-sea-salt sulfate (13–16%), ammonium (10–12%), EC (4–10%), mineral dust (2–5%) and sea salt (3–4%). This chemical composition is in agreement with those reported in the literature for most European environments. On an annual scale, Paris (URB and SUB sites) exhibits its highest PM2.5 concentrations during late autumn, winter and early spring (higher than 15 μg m−3 on average, from December to April), intermediates during late spring and early autumn (between 10 and 15 μg m−3 during May, June, September, October, and November) and the lowest during summer (below 10 μg m−3 during July and August). PM levels are mostly homogeneous on a regional scale, during the whole project (e.g. for URB plotted against NER sites: slope = 1.06, r2=0.84, n=330), suggesting the importance of mid- or long-range transport, and regional instead of local scale phenomena. During this one-year project, two thirds of the days exceeding the PM2.5 2015 EU annual limit value of 25 μg m−3 were due to continental import from countries located northeast, east of France. This result questions the efficiency of local, regional and even national abatement strategies during pollution episodes, pointing to the need for a wider collaborative work with the neighbouring countries on these topics. Nevertheless, emissions of local anthropogenic sources lead to higher levels at the URB and SUB sites compared to the others (e.g. 26% higher on average at the URB than at the NWR site for PM2.5, during the whole campaign), which can even be emphasised by specific meteorological conditions such as low boundary layer heights. OM and secondary inorganic species (nitrate, non-sea-salt sulfate and ammonium, noted SIA) are mainly imported by mid- or long-range transport (e.g. for NWR plotted against URB sites: slope = 0.79, r2=0.72, n=335 for OM, and slope = 0.91, r2=0.89, n=335 for SIA) whereas EC is primarily locally emitted (e.g. for SOR plotted against URB sites: slope = 0.27; r2=0.03; n=335). This database will serve as a basis for investigating carbonaceous aerosols, metals as well as the main sources and geographical origins of PM in the region of Paris.
