Summary: Particulate matter air pollution is a leading cause of global mortality, and many low- and middle-income countries lack sufficient ambient monitoring. Recent studies have utilized low-cost sensors to address these data gaps. In this study, different brands of low-cost sensors in Africa were compared, and it was found that each type of low-cost sensor PM2.5 is strongly correlated with reference PM2.5, but biased high for ambient mixture of sources found in Accra, Ghana.

Summary: Mining-induced coal dust causes respiratory diseases, especially coal workers' pneumoconiosis (CWP). Current underground monitors are costly and not suitable for regular sample monitoring. Low-cost PM sensors offer a potential solution but require precise calibration. This study calibrated Plantower PMS5003 sensors and evaluated other commercially available PM sensors, demonstrating the feasibility of low-cost sensors for real-time personal coal dust monitoring if a robust calibration model is applied.

Summary: In this article, two algorithms are proposed to denoise and calibrate low-cost sensors used in IoT monitoring platforms. The first method, TPB-D, achieves signal denoising by projecting the daily signals of the sensor onto a subspace generated by reference instruments. The second method, TPB-C, corrects and calibrates the daily sensor signals by linear mapping with regularization based on the subspace produced by the reference database.

Summary: The availability of low-cost sensors (LCSs) and low-cost monitors (LCMs) for air quality monitoring has attracted attention in recent years. Despite concerns about their data quality, they are seen as a potential alternative to the expensive and high-maintenance regulatory monitoring stations. However, comparing the performance of LCSs in different studies is challenging due to varying test conditions and metrics. This research aimed to evaluate the performance and application areas of two PM sensor models based on the guidelines provided by the U.S. Environmental Protection Agency (EPA). The findings suggest that improvements are needed to enhance the effectiveness of the EPA guidelines.

Summary: Air quality, both indoor and outdoor, is crucial for public health. This study introduces a new methodology using low-cost sensors and source apportionment techniques to understand the importance of different air pollution sources on indoor air quality. The results demonstrate the highest concentrations of PM in the bedroom, the highest PM spikes in the kitchen during cooking times, and the highest PM1 concentrations in the office due to outdoor infiltration. Source apportionment analysis shows that up to 95% of PM1 comes from outdoor sources in all rooms.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
