“…And through data measured by UAV, we could analyze the vertical distribution characteristics of the PM concentration in the dry bulk port and locate continuous measurement instruments at the inflection point of the distribution. On this basis, combined with spatial analysis and regression techniques [40], we can adequately and reliably evaluate the environmental quality of the port.…”

Knowing the vertical distribution of ambient particulate matter (PM) will help port authorities choose the optimal dust-suppression measures to reduce PM concentrations. In this study, we used an unmanned aerial vehicle (UAV) to assess the vertical distribution (0-120 m altitude) of PM in a dry bulk port along the Yangtze River, China. Total suspended particulates (TSP), PM10, and PM2.5 concentrations at different altitudes were measured at seven sites representing different cargo-handling sites and a background site. Variations in results across sites make it not suitable to characterize the vertical distribution of PM concentration at this port using simple representative distributions. Bulk cargo particle size, fog cannon use, and porous fence all affected the vertical distribution of TSP concentrations but had only minor impacts on PM10 and PM2.5 concentrations. Optimizing porous fence layout according to weather conditions and cargo demand at port have the most potential for mitigating PM pollution related to port operation. As ground-based stations cannot fully measure vertical PM distributions, our methods and results represent an advance in assessing the impact of port activities on air quality and can be used to determine optimal dust-suppression measures for dry bulk ports.

“…Particulate matter (PM) determines the air quality and main source of high number of PM is power plants, industrial infrastructure, automobiles, or fire. PM monitoring is performed by air sampling stations, employing beta‐attenuation monitoring or tapered element oscillating microbalance instrument . These methods are accurate and can produce high‐throughput PM data.…”

performed at home and results can be integrated by online interfaces. [5] The test results and diagnostic information can be analyzed by the medical professionals from remote locations, improving the connectivity of central hubs to the public venues.Numerous scientific discoveries have been made in advanced settings and wellequipped laboratories. The necessity and complexity of these environments limit access to research equipment worldwide. Thus, decentralization of research laboratories has become an alternative solution to improve access to experimentation in field conditions. For instance, a paper origami microscope [6] that fit into a palm of a student made a powerful investigation tool for environment and materials. A detailed analysis of sound recordings by smartphones enabled identification of distinct mosquitoes. [7] These fielddeployable devices and platforms have stimulated emergence of citizen scientists, a population that collectively performs scientific inquiries in public settings.Rich biomolecular measurements from field-portable devices improve the quality of results in terms of accuracy and depth. Monitoring multiple blood markers has enabled diagnostic precision and thorough scientific investigation of blood constituent in patients. Therefore, field-deployable devices should ideally have multiplexed detection of target specimens. Design of such multiplexed detection technologies requires decent complexity at low cost for wide-scale adoptability.In this article, we provide an overview of field-compatible devices with high parameter analysis capabilities for both health monitoring purposes and scientifically enlightening Global health issues are increasingly becoming critical with high fatality rate due to chronic and infectious diseases. Emerging technologies aim to address these problems by understanding the causes of lethal conditions and diagnosing symptoms at early stage. Existing commercial diagnostics primarily focus on single-plex assays due to ease-of-use, simplicity in analysis, and amenability to mass manufacturing. Many research grade devices have utilized only a few molecular and morphological signatures in bodily fluids. However, multiplex devices can improve accuracy, sensitivity, and scalability of research and diagnostic devices. This review presents multiplex assays that utilize optical, electrical, and chemical methods and materials that have the potential to improve portable point-of-care diagnostics. The critical role of emerging optical and complementary assays with multiple contrast mechanisms is investigated to enable highly multiplex analysis in field settings. Multiparameter portable devices for field applications toward health monitoring, food testing, air quality monitoring, and microanalysis in other extreme conditions are examined. Current trends indicate the need for validation of health diagnosis based on a large number of biomarkers in randomized clinical trials. Advanced digital analysis, crowdsourced solutions, and robust user interfaces will become an integral ...

“…Air pollution is considerable environmental health issue as it is reported that around 7 million people died in 2012 as a result of air pollution exposure from both outdoor and indoor emission sources [ 1 ]. Particulate matters (PMs) are well-known to have harmful impacts on human health [ [2] , [3] , [4] ]. Many studies have indicated a statistical relation between particulate maters and health issues, including respiratory and cardiovascular and genotoxic hazards [ [5] , [6] , [7] , [8] , [9] ].…”

“…The air pollution challenge of particulate maters is especially problematic in many cities of Iran including Ahwaz, Khorramabad, Tehran, Sabzavar, Mashhad, Zabol, Zahedan, Kermanshah, Gonabad etc. where particulate pollution is two to ninety times higher [ 2 , [15] , [16] , [17] , [18] , [19] ]. Because of these impacts, particulate matter levels are regularly monitored in numerous countries and managed according to the local, regional and in international standards.…”
