Summary: The proximity of West Africa to the Sahara Desert leads to significant power generation reductions in photovoltaic (PV) systems due to soiling caused by particulates settling on solar panel surfaces. Existing global PV soiling models have limitations in this region due to the accuracy of input PM concentration values, methods for computing power loss, and the use of decentralized solar systems. In this study, a new methodology based on the Coello framework is developed and applied, reducing error in soiling-related power loss estimates by approximately 50%. The study also finds that soiling losses can exceed 50% in highly affected locations during the Harmattan season.

Summary: Field measurements conducted at the Atlas Mohammed V atmospheric observatory in the Middle Atlas Mountains of North Africa revealed that the high-altitude aerosol composition is influenced by regional and transregional transport of emissions. During periods of low wind speeds, the aerosol chemical composition is mainly dominated by suspended dust and ionic species.

Summary: This study examines the seasonal variation of aeolian dust sources in the northeast Arabian Sea through the analysis of wet deposit particulate samples. The mineralogical composition and isotopic signatures reveal that the Arabian Peninsula and Northeast Africa are the dominant dust sources during the monsoon period, while the Thar desert and Southwest Asia become more prominent at the end of the monsoon.

Summary: This study investigates the wet deposition of particulate matter in the Northeastern Arabian Sea during the southwest monsoon, focusing on major elements, rare earth elements, mineralogical composition, and isotopic compositions. It found significant temporal variability in REEs patterns, mineral compositions, and isotopic compositions, indicating changing dust sources during different phases of the monsoon season. The identified sources using geochemical tracers were supported by satellite images and back-trajectory analyses.

Summary: Amorphous silicate samples with enstatite and forsterite compositions were synthesized by mechanical milling of SiO2-MgO and SiO2-Mg(OH)2 mixtures. The presence of H2O or OH bonds significantly influenced the final products after crystallization, with enstatite compositions transforming into forsterite with small amounts of amorphous silica SiO2 and enstatite, while forsterite compositions remained as forsterite. These findings suggest the importance of water content in the synthesis of amorphous silicates.

Summary: We investigated the mineralogy of global surface soils, which are likely similar to atmospheric dust aerosols, using reflectance and transmission measurements in visible, shortwave, and longwave infrared regions. Spectroscopy proved to be complementary to other techniques and exhibited better identification of specific minerals in these samples. Our findings can contribute to the enhancement of global soil atlases and the interpretation of data obtained from remote sensing instruments.

Summary: This study emphasizes the importance of investigating the sources of Saharan dust (SD) and their impact on atmospheric particles, including mass concentration, size distribution, and composition. SD events were associated with lower boundary layer heights and influenced the concentrations of PM1-10 and CO. The contribution of SD to PM10 and PM2.5 mass concentrations was approximately 30.9% and 19.4%, respectively. The behavior of PM and specific major and trace elements varied depending on the origin of the dust, affecting the deposition of inhaled aerosol in the respiratory tract.

Summary: The study reveals an increase in dust concentration in the atmosphere of southern Spain, with different origins and characteristics. The morphoscopy of quartz grains can serve as a fingerprint for the provenance of dust, while the characteristics and origins of dust can be determined using methodological techniques.

Summary: Discordant iron-rich ultramafic pegmatites (IRUPs) intersect with the UG2 chromitite in the Bushveld Complex. The effects of IRUP interactions on the UG2 ore mineralogy and PGE grade were evaluated based on borehole profiling and detailed analysis of mineral textures and compositions. The interaction between IRUP and UG2 occurred at different scales, resulting in local and large-scale mineralogical changes in UG2.

Summary: This study analyzed sediment samples from the southern slope of the Mariana Trench and found that the mineral composition of the trench sediments mainly includes quartz, feldspar, mica, pyrite, apatite, and clay minerals. During the Last Glacial Maximum, increased input of volcanic matter led to changes in mineral composition and the formation of laminated diatom mats, indicating the sensitivity of trench sediment mineralogy to paleoclimate and paleoceanography.

Summary: Despite the lack of sufficient investigation on lung cancer cases among South Korean sanitation workers exposed to carcinogens, this study revealed that sanitation workers are indeed exposed to respirable crystalline silica (RCS). The study found that exposure levels to RCS are influenced by various factors, with special attention needed for handling coal briquette ash and road cleaning tasks involving blowers.

Summary: A literature survey revealed that several wild indigenous Southern African fruits had not been previously evaluated for their proximate and amino acid composition, as well as total energy value. The nutritional values of C. edulis, H. lucida, P. reclinata, and M. mochisia are being reported for the first time. The fruits contain essential amino acids but are generally a poor source of proteins compared to the recommended daily intake.

Summary: The study found that road dust in Dhaka city is heavily enriched with arsenic, possibly driven by alkaline pH conditions controlled by carbonate minerals, which could potentially trigger the release and mobilization of arsenic into the environment. Monte Carlo simulation-based health risk forecast suggested that the probability of arsenic-associated cancer risk greatly exceeded the threshold for both adults and children, with children being more vulnerable. Sensitivity analysis indicated that arsenic concentration and exposure duration had the most significant impact on risk estimation.

Summary: This article compares and assesses a high-resolution regional desert dust reanalysis with satellite-based and ground-based observations. The assessment shows that the reanalysis is consistent with satellite and ground-based data in capturing dust sources and seasonal variations. However, the reanalysis slightly overestimates dust emissions from source regions and underestimates transported dust over outflow regions. Rating: 8 out of 10

Summary: This study investigated the interactions, transport, and fundamental concepts of particles and their associated co-transported matter (CTM) in the aquatic environment. The researchers emphasize the importance of understanding the transport of particle-associated CTM and the assumptions in generic models. They also highlight the need for interdisciplinary collaborations and a consistent terminology to foster progress in research on anthropogenic carrier particles.
