Iraq is ranked among the nations most adversely affected by increased air pollution. This research utilized Sentinel-5P imagery and Geographic Information Systems (GIS) to monitor and assess gaseous pollutants, as well as to delineate the spatial distributions of these pollutants across Iraq. The methodology involved the systematic mapping of sulphur dioxide (SO₂), nitrogen dioxide (NO₂), and aerosol index (AI). The research findings demonstrated robust monitoring capabilities and precise outcomes, juxtaposed with historical data and prior investigations. The observed concentration values ranged between 0 and 240.2 μg/m² for SO₂, from 0 to 4.6 μg/m² for NO₂, and from -1 to 2.75 for AI. A few provinces, such as Baghdad in the center, Basra in the south, in addition to Kirkuk and Nineveh in the north, were recognized as the most severely impacted by air pollution. The current study emphasizes the importance of air pollution monitoring in Iraq, particularly in the highlighted hotspots. Such observations are crucial in formulating pollution-mitigating strategies and improving air quality in affected areas.

This research aims to assess the viability and suitability of Ferrock as an alternative to concrete for constructing foundations. The study evaluates the performance of Ferrock in foundation applications, compares its costs with traditional concrete, and examines the benefits of using Ferrock for foundations. To achieve these objectives, the utilization of Staad Pro and Foundation software is done to analyze the performance of Ferrock foundations. A cost-benefit analysis, considering factors like material costs, construction techniques, and maintenance requirements to determine the economic feasibility of Ferrock as a substitute for concrete and the potential to reduce carbon emissions, and promote environmentally friendly construction practices is also done. The research findings indicate that Ferrock exhibits promising performance characteristics for building foundations. It demonstrates comparable strength to traditional concrete while offering potential environmental benefits. Although implementing Ferrock may require an initial investment, the long-term advantages of reduced maintenance costs and improved sustainability contribute to its overall value proposition. © 2023 Bumi Publikasi Nusantara.

Abstract Even though there are expert monitoring and assessment stations in large cities, air quality monitoring and measurement have a high cost and face significant issues. Data on air pollution can be acquired from remote sensing satellites for large areas and at a reasonable expense to compensate for monitoring stations on the ground. This research presented a method for retrieving PM10 from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite Aerosol Optical Thickness (AOT) records. The study depends on a previously established equation to retrieve PM10 over Malaysia in September 2014. In Contrast Reduction Technique, we used Aerosol Robotic Network AERONET AOT to define the reference. The conversion factors, representing the relationship between AOT and PM10 satellite columns, were determined using a mathematical approach. The size and type of aerosol, relative humidity, and boundary layer height vary globally and seasonally, thus the AOT–PM10 relationship fluctuates spatially and temporally. The conversion factor was then applied to the MODIS image to predict the surface level of PM10 concentrations in micrograms via cubic meter (μg/m3). Moreover, the achieved correlation coefficient R2 of calculated PM10 based on ground truth data was equal to 0.92. Based on the results obtained from the thematic maps, PM10 levels are significantly higher in specific cities such as Kuala Lumpur and Johor. Where PM10 ranged from (26.5 to 72) µg/m3, while AOT values were between (0.12 and 0.83). It raises concerns about the environmental health threats and their relationship to air quality in these regions as a research topic.
