“…Marrakech and Tunis have 350 similar concentrations of 52 µg/m 3 and 58 µg/m 3 , respectively, due to the high traffic and combustion emissions (Kchih et al, 2015;Inchaouh, 2017). Agadir has more pollution (65 µg/m³) due to higher industrial emissions and the influence of sea salt due to its location along the Atlantic coast (Ajdour et al, 2019). Tetouan, which is located in the north of Morocco on the Mediterranean coast, has a low concentration.…”

Abstract. Field measurements were conducted to determine aerosol chemical composition in a newly established remote high-altitude site in North Africa to investigate the variations in aerosol composition useful in assessing global and regional changes in atmospheric composition. Particulate matter (PM10) filter samples (200) were collected at the Atlas Mohammed V atmospheric observatory (AM5) located in the Middle-Atlas Mountains in Morocco using a high-volume (HV) collector in a 12 h sampling interval from August to December 2017. The chemical composition of the samples was analyzed for trace metals, ions, elemental carbon, organic carbon, aliphatic hydrocarbons, and polycyclic aromatic hydrocarbon (PAHs) content. The results indicate that high-altitudes aerosol composition is influenced by both regional as well as trans-regional transport of emissions. However, local sources play an important role, especially during low wind speed periods, as observed for November and December. Despite the proximity of the site to the Sahara Desert, its influence on the atmospheric composition at this high-altitude site was mainly seasonal and accounted for only 14 % of the sampling duration. Background conditions at this remote site are characterized by low wind speeds (Av. 2.5 m/s) and mass concentrations in the range of 9.8 and 20 µg/m3. The chemical composition is found to be dominated by inorganic elements, mainly suspended dust (47 %) and ionic species (16 %), followed by organic matter (15 %), water content (12 %), and indeterminate mass (9 %). Biogenic organics contributed up to 7 % of the organic matter with high contributions from compounds such as Nonacosane, Heptacosane, and 2-Pentadecanone. The AM5 site is dominated by four main air mass inflow, which often leads to different aerosol chemical compositions. Mineral dust influenced was seasonal and ranged between 20 and 70 % of the PM mass with peaks observed during the summer and was accompanied by high concentrations of SO42− of up to 1.3 µg/m3. During winter, PM10 concentrations are low (

“…Likewise, the few studies conducted in Moroccan cities have also mainly reported PM 10 and some major gas-phase pollutant values such as O 3 , NO x , and SO 2 (Inchaouh et al 2017 ; Tahri et al 2017 ; Otmani et al 2020 ; Bounakhla et al 2023 ). Other air quality modeling studies investigated the PM 10 variation in some urban cities in Morocco based on the inventory of local anthropogenic emissions and the application of machine learning techniques to evaluate atmospheric circulation and PM 10 concentrations (Ajdour et al 2020 ; Khomsi et al 2020 ; Sekmoudi et al 2021 ; Saidi et al 2023 ). In some studies, gaseous pollutant levels with high ozone concentrations of up to 157 μg m −3 and PM 10 levels, exceeding the WHO threshold limits, have been reported during the summer and spring at urban sites in Marrakech and Kenitra, Morocco (Inchaouh et al 2017 ; Agbo et al 2021 ).…”

Particulate matter (PM) is an important component in the atmosphere, affecting air quality, health, radiation balance, and global climate. To assess regional air quality in the city of Fez, an intensive field campaign was carried out in the autumn of 2019 in the Middle Atlas region of Morocco. Aerosol sampling was performed simultaneously at two urban sites in the city of Fez: (1) Fez University (FU), a sub-urban site, and (2) Fez Parc (FP), an urban site located in the city center of Fez, using PM10 collectors. Various laboratory analyses were carried out, including PM mass, trace metals, inorganic ions, OC/EC, sugar compounds, and PAHs. The results indicate that the PM10 mass (61 ng m−3) was comparable at both sites, with a 37–107 ng m−3 range. Most of the 19 investigated PAHs at the FU site (10.2 ± 6.2 ng m−3) were low-molecular-weight PAHs, while the most abundant PAHs at the FP site (6.9 ± 3.8 ng m−3) were mainly higher-molecular-weight PAHs. A diagnostic ratio analysis at both sites indicated that PAHs originated from fossil fuel combustion and traffic emissions from diesel engines, with Ant/(Ant + Phe) and Flu/(Flu + Pyr) ratios averaging 0.22 and 0.84, respectively. PMF analysis identified traffic emissions as a major source (30%), with secondary inorganic aerosols (20%) and biomass burning (14%). Polar plots highlight the dominance of local anthropogenic activities in PM pollution, with vehicular emissions, industrial activities, and biomass burning. This study shows that local sources and combustion processes significantly contribute to PM10 sources in Morocco, providing insights into air pollution mitigation in North Africa.

“…The ambient particulate matter was studied in two European cities during New Year's fireworks [17]. The concentration and the distribution of airborne particles in were measured different cities through different researchers such as Beijing (China) [18], Wollongong (Australia) [19] Newmarket (UK) [20], Uttarakhand (India) [21], Agadir (Morocco) [22] main cities [23] and central and eastern region of Saudi Arabia [24]. One of the application to improve the human breathing zone in polluted are is by introducing a personalized air curtain 25.…”

Exposure to outdoor and indoor air particles (also known as particulate matter or PM) has attracted the interest of the scientific researchers around the world, this is because of the adverse health effects that particles have on the human. Smaller fractions of particulate matter (repairable range, ≤10 µm) give the greatest health problem, because they have the ability to reach deeper parts of the human respiratory system. Many countries have paid attention to the air pollution and made regulations to improve their indoor and outdoor air quality, Saudi Arabia, particularly Qassim region, has not given much attention to the problem of air contaminants in the ambient and indoor environments. In addition, ambient environmental parameters will be recorded. The results obtained from the indoor and outdoor measurements will help us to evaluate the air quality in Buraydah city for different seasons in the indoor and outdoor environments.
