Abstract At the turn of March and April 2024, most mainland Europe was afflicted by sand dust particles carried wind flow from Sahara Desert. As a result, Central experienced an exceptionally high increase in air pollution. In this work, impact Saharan event on PM10 characteristics urban natural locality Czech Republic investigated. concentrations before during were measured using Beta-Attenuation method. During event, they about 6–8 times higher than under normal atmospheric conditions, exceeding WHO guidelines up to 2 times. A potential effect terrain altitude local observed. Airborne collected then studied scanning electron microscopy combined with energy-dispersive spectroscopy (single-particle analysis sizes elemental composition) X-ray diffractometry (mineralogical composition). Surprisingly, particle size distribution not significantly affected advection, but its dependency sampling revealed. The dominant mineral calcite, which substantially altered composition. probably originated area, as amount anthropogenic pollutants detected negligible. Notably, carbon content lower compared usual PM10. elevated appear be relevant risk associated Europe. transported northern/north-western – Atlas region verified backward trajectory masses.

Improving the urban environment is an urgent task in fast-growing mid-sized cities of South Asia. Ambient air pollution worsened by unplanned land use and a lack green waterbodies, which combined cause rapid increase heat island (UHI) effect. This study focuses on pervasive ambient environment, primarily driven particulate matter (PM), presents dire public health threat. An in-situ investigation 48 sites but city, Mymensingh, Bangladesh, suggested that PM 2.5 concentration (118 ± 64 μg/m 3 ) about eight times higher than daily average WHO (15 ). Weekdays weekends do not show significant differences generation. Geospatial analysis suggests good quality conditions are found area, > 50% people exposed to 10 very unhealthy (≥151 Traffic commercial cover generate highest level. The monsoon climatic events control precipitation most influential factor diminishing concentrations. However, cities, like Mymensingh Bangladesh others throughout Asia, facing extreme severely impacts health. Therefore, more action-oriented research initiatives needed formulate policies pollution, considering local experiences, indigenous knowledge, logistics capabilities, cultural orientation, transparency, accountability, strong collaboration, cooperation, commitment among public-private partnership.
