• Abstract: This study examines how the desiccation of Utah Great Salt Lake GSL, exacerbated by anthropogenic changes, poses significant health risks, particularly communities mental health. Reduced water inflow has exposed the lakebed, increasing airborne particulate matter PM2.5 and dust storms, which impact air quality. By integrating diverse datasets spanning from 1980 to present including insitu measurements, satellite imagery, and reanalysis products this study synthesizes hydrological, atmospheric, and epidemiological variables to comprehensively track the extent of the GSL surface water, local air quality fluctuations, and their effects on community mental health. The findings indicate a clear relationship between higher pollution days and more severe depressive symptoms. Specifically, individuals exposed to 22 days with PM2.5 levels above the World Health Organizations 24 hour guideline of 15 ug per m3 were more likely to experience severe depressive symptoms. Our results also suggest that people experiencing more severe depression not only face a higher number of high pollution days but also encounter such days more frequently. The study highlights the interconnectedness of poor air quality, environmental degradation and mental health emphasizing the need for more sustainable economic growth in the region.

In a developing country like Bangladesh, where ready-made garments sector is one of the major sources of the total Gross Domestic Product (GDP), most of the wastes released from the garment factories are dumped into the nearest rivers or canals. To address this issue, we developed an Internet of Things (IoT)-based real-time water quality monitoring system, integrated with a mobile application.
