Pollution remains one of the most significant environmental challenges of the modern world, affecting air, water, soil, and overall ecosystem stability. This abstract provides an overview of major pollutants and the human activities that generate them. Air pollutants such as carbon monoxide, sulfur dioxide, nitrogen oxides, and particulate matter primarily originate from transportation,...

19. SOURCES OF AMBIENT FINE PARTICULATE MATTERS IN OSHAKATI, SWAKOPMUND AND WALVIS BAY, NAMIBIA USING POSITIVE MATRIX FACTORIZATION: A LONG-TERM PROJECT FROM 2026

Anna Alfeus (University of Namibia)

Introduction: Fine particulate matter is a toxic air pollutant with an aerodynamic size of less than 2.5 microns that can endanger human health and climate. The WHO have set and recently revised air quality guidelines upon which countries can use as a yardstick to set their own air quality standards. Namibia does not have air quality standards, leading to unregulated levels and unknown sources...

30. The INAIL BRiC CELLOPHAN project: Characterization of Emissions in Workplaces of Airborne Microplastics and Nanoplastics

Dr Adriana PIETRODANGELO (National Research Council (Consiglio Nazionale delle Ricerche) - Institute of Atmospheric Pollution Research, Italy)

Workers are mainly exposed to micro- and nano-plastics (MNP) by inhalation. Air concentration of MNP in indoor environments can be far higher than outdoors, particularly in workplaces where production, use or disposal of plastic materials is carried out.
However, differently from engineered MNP, secondary MNP released in workplaces remains uncontrolled, since few data exist on MNP indoor air...

36. Sampling and Identifying Airborne Microplastics: Techniques, Findings, and Challenges

Nor Ruwaida Binti Jamian (Universiti Teknologi Malaysia)

03/12/2025, 16:35

Airborne microplastics (MPs) have emerged as an increasingly recognized component of atmospheric pollution, yet their sampling, characterization, and quantification remain challenging due to their diverse physical forms and low ambient concentrations. This sharing session provides an overview of the approaches and research in microplastics sampling in outdoor and indoor air environments....
