Oman National Air Pollution Analysis Project

Oman’s Environment Authority (EA), in partnership with GUtech, launched a country-wide air pollution study in late 2025. The objectives are to analyse the chemical composition of fine particulates (PM₂.₅ and PM₁₀) and identify their natural versus industrial sources, thereby informing strategies to improve air quality, protect public health, and support applied research. In practice, this involves extensive field sampling and laboratory analysis: teams are installing specialized air monitors and filters, collecting samples in urban, industrial and rural locations, then using advanced scientific techniques to analyze pollutant chemistry. They will apply modern numerical and statistical models (such as source-apportionment and dispersion models) to trace pollution back to its origins and quantify environmental and health impacts.
Key Methodology: Installation of specialized air-quality monitoring equipment; collection of PM₂.₅/PM₁₀ samples in diverse environments; laboratory chemical analysis of the samples; and application of statistical source-apportionment and dispersion models to identify emission sources and assess their impacts.

Technologies and Models

The project team deploys portable air-sampling rigs (like the low-flow PM₂.₅/PM₁₀ samplers shown above) across Oman’s varied terrain. On-site equipment includes low-volume particulate samplers (tripod-mounted filters) to collect airborne dust and soot, alongside high-precision air sensors for real-time pollutant measurements.

Collected filters are sent to chemical labs for detailed speciation (e.g. metals, organics, minerals). In parallel, the team uses advanced numerical models – such as meteorological dispersion models and receptor/source-apportionment algorithms – to link measured pollutant levels with upwind sources.

These tools let researchers reconstruct the contributions of local industries, vehicle traffic, desert dust, and other sources to ambient PM concentrations.

• Monitoring Equipment: Certified analytical devices for PM₂.₅/PM₁₀ sampling and gas measurement (analogous to the instruments in Oman’s national monitoring network).

• Data Analysis: Advanced lab techniques (e.g. mass spectrometry, X-ray fluorescence) for chemical composition.

• Numerical Models: Modern statistical and numerical models for source apportionment (e.g. factor analysis) and air dispersion, used to pinpoint emission sources and quantify exposure.

Geographic Coverage and Sampling Sites

Fieldwork spans all major regions of Oman. Specialized teams have begun sampling in multiple governorates (urban centers, industrial zones and remote areas) to ensure representative . Planned sites include Muscat (urban), Sohar and Duqm (industrial complexes), coastal locations and interior desert areas, as well as mountain and rural sites (e.g. in Al Dhofar and Al Sharqiyah). By sampling across the country, the project will capture Oman’s diverse climates and emission profiles. This ensures the resulting dataset reflects the spatial variability of air pollution in Oman.
