Detection of changes in water salinity based on patrol monitoring and remote sensing methods

A significant number of rivers heavily influenced by anthropogenic pressures are not monitored (or monitored infrequently). For this reason, there is a need to develop modern methods allowing for the ongoing observation of water quality parameters, of which salinity is a key one. As a result of patrol monitoring information on changes in conductivity in the longitudinal profile of the Oder were obtained. The aim of this study is to correlate these results with Sentinel – 2 satellite imagery (VIS + NIR bands) to verify the hypothesis that remote sensing methods can be used to detect salinity changes in inland flowing waters. For this purpose data acquired with the multi-parameter probe during field expeditions, remote sensing methods and Geographical Information Systems tools (such as inter-bands algebra, pixel value extraction) and statistical methods were used. We concluded that the best spectra for salinity detection is Green as well as Salinity Index (SI) mostly showed statistically significant correlations. Remote sensing can be successfully used to detect changes in the salinity of flowing waters.

Environmental Drivers of the Divergence of Harveyi Clade Pathogens with Distinctive Virulence Gene Profiles.

Fish and shellfish pathogens of the Harveyi clade of the Vibrio genus cause significant losses to aquaculture yields and profits, with some of them also causing infections in humans. The present study aimed to evaluate the presence of Harveyi clade fish and shellfish pathogens and their possible diversification in response to environmental drivers in southeastern USA waters. The presence and abundance of potential pathogens were evaluated via the detection and quantitation of six Harveyi-clade-specific virulence genes (toxR, luxR, srp, vhha, vhh, and vhp; VGs) in environmental DNA with clade-specific primers. The environmental DNA was obtained from water and sediments collected from three Georgia (USA) cultured clam and wild oyster grounds. In sediments, the VG concentrations were, on average, three orders of magnitude higher than those in water. The most and least frequently detected VGs were vhp and toxR, respectively. In water, the VGs split into two groups based on their seasonal trends. The first group, composed of luxR, vhp, vhha, and vhh, peaked in August and remained at lower concentrations throughout the duration of the study. The second group, composed of toxR and srp, peaked in June and disappeared between July and December. The first group revealed a high adaptation of their carriers to an increase in temperature, tolerance to a wide range of pH, and a positive correlation with salinity up to 25 ppt. The second group of VGs demonstrated a lower adaptation of their carriers to temperature and negative correlations with pH, salinity, potential water density, conductivity, and dissolved solids but a positive correlation with turbidity. No such trends were observed in sediments. These data reveal the role of VGs in the adaptability of the Harveyi clade pathogens to environmental parameters, causing their diversification and possibly their stratification into different ecological niches due to changes in water temperature, acidity, salinity, and turbidity. This diversification and stratification may lead to further speciation and the emergence of new pathogens of this clade. Our data urge further monitoring of the presence and diversification of Harveyi clade pathogens in a global warming scenario.

Multi-Decadal Impact of Mine Waters in Przemsza River Basin, Upper Silesian Coal Basin, Southern Poland

Anthropogenic increases in the salinity of surface waters are referred to as secondary salinization. In surface waters, salinity levels can vary significantly due to various natural and anthropogenic influences. This article presents multi-decadal observations of changes in surface water salinity in the highly industrialized region in southern Poland. The case study of the Przemsza River is an example of the significant impacts of industrial, mainly coal mining, activities that have changed the chemical and biological characteristics of water bodies. The presented research revealed that impacts on salinity and water body status due to mining discharges will be difficult or even impossible to restore, considering the process of transition of the coal sector. In the Przemsza river basin, almost 42% less mine water was discharged in 2023 than in 1991. Parallelly, the salinity of mine waters discharged from deeper levels of active coal mines has increased due to the geochemical gradient (the total load of chlorides and sulfates was 534.8 MgCl−+SO42− per day in 1991, while in 2023 the total salinity load was 480.1 MgCl−+SO42− per day). Moreover, of the 19 active mine water discharges in 1991, only 11 remain in 2023, while the observed salinity of surface water in the Przemsza watershed increased rapidly from an average of 2000 µS·cm−1 to 6700 µS·cm−1 due to the significant drought and adverse hydrological conditions, which represent low flows never observed before (three times lower flows in the mouth of the Przemsza River in the period 2021–2023 compared to the previous decades 1991–2020). Impacts on water bodies will continue to occur regardless of mining activities in the area—it should be noted that at the end of exploitation, mine water rebound and flooding do not automatically reduce long-lasting impacts on surface waters. Therefore, salinization is a growing threat that might be amplified by climate change. While industrial and urban impacts on surface water change its characteristics, the future challenge of proper water management with a holistic approach is necessary with proper monitoring data collection and river flow-dependent and surface water salinity-dependent discharge of wastewater in the river basin.

Future impacts of reduced freshwater inflow and sea level rise on forage fish and their predators in Apalachicola Bay, Florida

Estuarine ecosystems often support large populations of forage fish, but these small-medium sized fish and the predators they feed may be affected by multiple climate change and human-induced stressors. In the Apalachicola Bay estuary, Florida, USA, reduced freshwater inflow and sea level rise are two prevalent stressors, and little is known about how these environmental changes might impact the forage fish species who inhabit the estuary. This study uses a food web model for Apalachicola Bay to simulate the impacts of future changes in water temperature and salinity on forage fish and predator species who inhabit the estuary. Water temperature and salinity conditions were based on previously developed simulations of reduced freshwater inflow and sea level rise in Apalachicola Bay from 2020 to 2049. These simulated environmental changes were applied as forcing functions in the food web model to drive shifts in species biomasses over time. This study centered on changes in biomass for two highly abundant forage fish species, juvenile silver perch (Bairdiella chrysoura) and juvenile pinfish (Lagodon rhomboides), as well as their major predators, spotted seatrout (Cynoscion nebulosus) and inshore lizardfish (Synodus foetens). These changes were assessed at both 10- and 30-year time intervals relative to 2019, along with an examination of forage fish consumption by their predators. Juvenile silver perch biomass increased across all scenarios and time scales, while juvenile pinfish biomass decreased. Consumption of juvenile silver perch by spotted seatrout increased across all scenarios and time scales, and consumption of juvenile pinfish by inshore lizardfish decreased, in concordance with the trends in prey biomass. Both spotted seatrout and inshore lizardfish biomasses decreased across future scenarios, though the high biomass of juvenile silver perch may have played a role in stabilizing the decline of spotted seatrout. Changes in forage fish biomasses and their impacts on predator species as a result of reduced freshwater inflow and sea level rise have implications for ecosystem productivity and the fisheries of the region.

AN EFFICIENT HIGH POWER WATER DUMMY LOAD AT 2.45 GHz

A water dummy load developed as an element of equipment in the composition of a microwave atmospheric pressure plasmatron operating at a frequency of (2450±50) MHz is described. The load is created on the base of a rectangular waveguide with a cross-section of 90x45 mm. The simulation results carried out by CST Microwave Studio shows that the return losses reach -42 dB at 2.45 GHz. In the frequency band from 2 to 2.9 GHz, the load provides a voltage standing wave ratio (VSWR) of at least 1.2. The effect of changes in water temperature and salinity on the device characteristics is studied. The load is manufactured and successfully used as part of experimental waveguide paths.

Influence of water saliny changes on the operation of the RAS biological treatment system under low temperature conditions

In fish-breeding circulation systems the change-over of a biofilter from operation in fresh water conditions to sea water conditions (or vice versa) requires a smooth gradual transition. However, a one-time water change is feasible faster and technologically easier. This determined the relevance of the study. The goal was to determine the influence of one-time water salinity changes (sea to fresh and fresh to sea) on the ability of the activated sludge biocenosis of biofilters to maintain or restore its activity in a cold-water RAS. Six model biofilters were filled with sea water and six with fresh water. With a simultaneous decrease of water temperature from 21 to 9 °C, at the first stage a start-up period of biological treatment was carried out. At the second stage — in a stable operating regime, sea water was simultaneously changed to fresh water, and fresh water to sea water. Concentrations of ammonium, nitrites and nitrates were determined at the start of experiment, then on the next day after a bacterial culture and ammonia as a source of ammonium nitrogen adding, and then — 2 times a week. A steady decrease in the concentration of ammonium in water to 0.2 mg/l, nitrite — to 0.3 mg/l was considered as the indicator of the end of each stage. The duration of the start period of biological treatment in both fresh and sea water was approximately the same and amounted to 138 and 134 days, respectively. With the simultaneous change of sea water to fresh or fresh water to sea, the complete destruction of the biofilter activated sludge biocenosis didn’t happen, that indicated by the continuing increase of the nitrates concentration. However, the ability of the biofilter biocenosis to purify circulating water from ammonia nitrogen and nitrites naturally decreases with the following gradual performance restoration. The adaptation of biofilter biocenosis to work under conditions of rapid desalination was 1.5 times faster than the adaptation of biocenosis to rapid salination.

Effect of Physical Factors on Milt Quality of Malabar Grouper, Epinephelus Malabaricus in Summer and Winter Season

A study was conducted to test the effect of physical factors such as temperature, salinity, and pH on spermatozoa motility of Malabar grouper (Epinephelus malabaricus). Mature and healthy male fishes were collected from the Red Sea during the summer and winter seasons for milt collection. Milt quality was assessed for colour, volume, sperm cell concentration, motility, and viability. Sperm motility was tested under different water temperatures, salinity, and pH media. A significant difference (P < 0.01) in sperm cell concentration (density), sperm motility (%), and viability (%) was observed between the summer and winter seasons. Changes in water temperature, pH, and salinity influenced sperm motility (%) and motility duration (min). Low pH and salinity caused adverse effects on spermatozoa motility. The results of the study are useful for the germplasm conservation of Malabar grouper, E.malabaricus.

Indonesia's economic and environmental resilience in the face of climate change: Analysis and implementation strategies

Backgorund: Climate change is a significant threat to Indonesia, an archipelago that is vulnerable to the negative impacts of this phenomenon. This study aims to identify the effects of climate change in Indonesia and evaluate mitigation and adaptation strategies needed to improve economic and environmental resilience. Based on climate change projections, increases in surface temperature, changes in rainfall patterns, sea level rise, and changes in water salinity have negative impacts on various sectors such as agriculture, fisheries, infrastructure, and public health. Method: The research method includes secondary data analysis from various official sources and a study of relevant literature, with an analytical descriptive approach to identify critical challenges and necessary strategies. Findings: The results show that limited fiscal space and the need for budgetary reform are significant challenges that need to be addressed through the introduction of a carbon tax, budgetary incentives for green technologies, and the removal of fossil fuel subsidies. In addition, mobilization of non-budget funding sources is needed to support green projects, with strategies such as the development of public-private partnerships, access to international funds, and technical capacity building. Conclusion: In conclusion, implementation of the recommended mitigation and adaptation strategies can increase Indonesia's resilience to climate change, reduce its risks and negative impacts, and ensure the sustainability of economic and social development. Novelty/Originality of this study: This research provides practical guidance for policymakers to develop effective strategies to deal with climate change

Acute warming tolerance (CTmax) in zebrafish (Danio rerio) appears unaffected by changes in water salinity.

Tolerance against acute warming is an essential trait that can determine how organisms cope during heat waves, yet the mechanisms underlying it remain elusive. Water salinity has previously been suggested to modulate warming tolerance in fish and may therefore provide clues towards these limiting mechanisms. Here, using the critical thermal maximum (CTmax) test, we investigated whether short (2 hours) and long (10 days) term exposure to different water salinities (2 hours: 0-5 ppt, 10 days: 0-3 ppt) affected acute warming tolerance in zebrafish (N=263). We found that water salinity did not affect the warming tolerance of zebrafish at either time point, indicating that salinity does not affect the mechanism limiting acute warming tolerance in zebrafish at these salinity ranges, and that natural fluctuations in salinity levels might not have a large impact on acute warming tolerance in wild zebrafish.

Reproductive conditioning, spawning induction and early development of the estuarine Caribbean clam, Polymesoda arctata (Deshayes, 1854), under hatchery conditions

Polymesoda arctata is a Caribbean estuarine clam commercially important that currently is considered threatened. The reproductive conditioning, spawning and early development were evaluated under laboratory conditions using organisms collected in the lagoon system of Ciénaga Grande de Santa Marta (Colombian Caribbean) between December 2020 and May 2021. Two reproductive conditioning experiments were conducted over 7 weeks, examining the frequency of mature animals in the natural environment (controls) and in the laboratory under two water temperatures (26 and 29 °C) and different salinity regimes (constant at 5 and 15 ppt, increasing from 5 to 15 ppt, and decreasing from 15 to 5 ppt). One spawning experiment was done, comparing the spawning response of adult clams exposed to various stimuli (changes in water temperature and salinity, flow of seawater irradiated with UV light, addition of a high concentration of food and sperm to the water, as well as injections of serotonin and KCl into the foot and/or adductor muscle). Higher frequencies of mature clams were observed after 2 to 5 weeks of reproductive conditioning at a low temperature (26 °C) and under a constant salinity regime (at 5 or 15 ppt). Higher percentages of spawning and post-stimulation survival as well as spawning response speed were observed in specimens injected in the foot with a low concentration of serotonin (0.4 mL at 20 μM). The time of spawning response onset was shorter in males than in females. The fecundity increased with the live weight of the females, showing an average value of 3.4 × 106 oocytes per female. The early development of the estuarine clam from oocyte to juvenile stage was described in detail. The growth rates of larvae and spat were relatively high but their survival values were low, showing the need for additional research on the larval and post-larval rearing.

Gill transcriptomes analysis of Takifugu obscurus, Takifugu rubripes and their hybrid offspring in freshwater and seawater

Osmoregulation is essential for aquatic organisms to balance their internal fluids and ions and adapt to environmental changes. The gills are a crucial organ for maintaining osmotic balance in fish by regulating the uptake and excretion of ions. Changes in the salinity of the aquatic environment can lead to alterations in the expression of genes within gill cells, which helps to maintain the internal salinity balance and allows the fish to adapt to different salinity levels. In this study, we used transcriptomic data of the gill from the euryhaline Takifugu obscurus and the stenohaline Takifugu rubripes, as well as their hybrid offspring (Tor1 and Tor2), to investigate how the gill contributes to osmoregulation in response to freshwater and seawater. Our study revealed 8 commonly differentially expressed genes among these four fish species. Analysis of the T. obscurus transcriptome data has demonstrated that SLC1a5, a member of the solute carrier (SLC) family, and Gper1, a G-protein coupled estrogen receptor 1-like, are enriched in many biological processes and might be important for its osmoregulation in freshwater. Furthermore, PDE8B, Lrrc9 and Cplx4 might be important osmoregulatory genes that are inherited by offspring in T. obscurus. Moreover, upon encountering changes in water salinity, T. rubripes and the hybrid offspring Tor1 reveal a marked concentration of differentially expressed genes in metabolic pathways within their gills, whereas T. obscurus and the hybrid offspring Tor2 show a more even distribution of DEGs across various signaling pathways. Finally, the Pearson correlation analysis revealed that the T. rubripes displayed a significant correlation with Tor1, while the T. obscurus was significantly related to Tor2. Overall, this study provides a theoretical foundation for understanding the salinity adaptation mechanisms in hybrid offspring of Takifugu, and holds significant implications for guiding the breeding of economically valuable Takifugu strains with improved traits.

Observations on the Distribution and Effect of Salinity on a Little Known Plant, <I>Mimulus orbicularis</I> Wall. Ex Benth. (Scrophulariaceae)

Mimulus orbicularis Wall, ex Benth., occasionally found in brackish water lakes, ditches, slacks and often in abandoned ricefields near estuaries and the coastal belt of Eastern India, is a rare aquatic plant. Very often the plants have been found to disappear from the habitat due to some ecological or anthropogenic factors. It is observed that the plant has very little potential for modulating its life cycle strategies in the same habitat. Though populations were recorded in three different localities in India, survival of this species in a parmanent habitat is still a question due to its 'nomadic distribution'. On account of this population behaviour, the collection of this species by many workers in the past has been inadequate. Occurrence of this plant in new localities, extent of distribution and some changes in the morphological characteristics with the change of water salinity and some chemical components of water are discussed in this paper.

Study on Ferritin Gene Expression to Evaluate the Health of White Leg Shrimp (Litopenaeus vannamei) Postlarvae Due to Changes in Water Temperature, Salinity, and pH

The growth and survival of marine organisms are influenced by environmental factors such as water temperature, salinity, and pH. Unsuitable environmental conditions may negatively impact marine organisms. The white leg shrimp (Litopenaeus vannamei), a euryhaline organism highly adapted to salinity, is a valuable species for aquaculture. This study examined the effects of water temperature, salinity, and pH on the health of postlarvae L. vannamei. Stress levels within the organisms were analyzed through the expression of a biomarker gene. Ferritin was selected as the biomarker gene for analysis. The experimental animal samples used were the hepatopancreas of L. vannamei postlarvae. The analysis was performed by qRT-PCR. The results showed that the adaptation of L. vannamei postlarvae to temperature was dependent on salinity. Under low-salinity conditions (5 psu), ferritin expression increased at 25 °C and 30 °C after 48 h of exposure; however, it decreased after 72 h of exposure. Under normal salinity conditions (27 psu), ferritin expression increased from 24 h to 72 h at water temperatures of 25 °C and 30 °C. These results indicate that low-salinity conditions may enable L. vannamei postlarvae to rapidly adapt to high temperatures. In conclusion, L. vannamei postlarvae adapt more efficiently to high temperatures under low-salinity conditions than that under high-salinity conditions. The results of this study could beneficially impact L. vannamei farming.

Spatial variation in grassland vegetation and herbage mass in the Ejina oasis along the Heihe River in the southern Gobi Desert, China

AbstractOur study area, Ejina, is located in the southern Gobi Desert, Inner Mongolia, China, where the annual precipitation is <50 mm and the annual potential evaporation is >3,600 mm. The Heihe River flows from the Qilian Range through the study area, and the desert landscape along the river includes oases formed by forests and grasslands. We established a survey area of approximately 1.5 ha in grassland facing a seasonal swamp, a branch of the Heihe River. We posed the following questions in this desert grassland: (1) how do soil water content (SWC) and salinity change with distance from the riverbank? (2) How do vegetation, aboveground biomass, and species richness change with distance from the riverbank? (3) How much can be supplied to grazing animals, and how many animals can be grazed? Our results indicated that (1) the SWC is high within 20 m of the riverbank and low beyond 20 m, the standing biomass is positively correlated with SWC, but there was no evidence of a correlation between salinity and distance to water; the electrical conductivity was high both inland and adjacent to the riparian swamp. (2) Vegetation could be classified to six classes, following a gradient from the riverbank (swamp margin) to the dry inland area beyond 20 m from the riverbank. Species richness and aboveground biomass were highly correlated. Classification result led us to recommend that generalist species tolerant of the distinct moisture gradient in the site be used in restoration efforts. (3) Per‐hectare aboveground biomass was 478.93 dry weight (dw) kg, 321.2 ha of equivalent grassland would be required to graze 100 goats annually.

Effect of water salinity on the focal tuning of an injected liquid lens used to modify the z-scan method

A water-injected liquid lens is fabricated to tune its focal length using the change in water salinity. It is found that when the salinity of water is changed from zero to 34.25%, the focal length can be changed by about 12.6 mm from 73.7 mm to 86.3 mm. A focal length resolution of approximately 0.75 × 10−2 mm and high temporal stability over a long period have been achieved for the lens foci. This lens is then used to modify the z-scan technique where the lens and the sample both remain fixed without displacement. The performance of the fabricated lens is evaluated by nonlinear refractive index measurement of a sample containing 10.82-pH-synthesized Silver nanoparticles suspended in water with 15 mM of concentration. For verification of the results, a nonlinear refractive index of (−10.6 ± 1.0) × 10−7 cm2 W−1 is firstly measured for the sample using a classical z-scan benefiting from a conventional focal-fixed lens. Interestingly, we found out that when the fabricated lens is replaced in the modified z-scan, the nonlinear refractive index of about (−8.1 ± 0.2) × 10−7 cm2 W−1 can be measured, indicating a similarity in the order and small difference in the coefficient compared to the classical z-scan. This outcome highlights the potential capability and simplicity of the fabricated lens in the modification of the classical z-scan technique.

Flocculation characteristics of suspended Mississippi River mud under variable turbulence, water and salt sources, and salinity: a laboratory study

Muddy sediment constitutes a major fraction of the suspended sediment mass carried by the Mississippi River. Thus, adequate knowledge of the transport dynamics of suspended mud in this region is critical in devising efficient management plans for coastal Louisiana. We conducted laboratory tank experiments on the sediment suspended in the lower reaches of the Mississippi River to provide insight into the flocculation behavior of the mud. In particular, we measure how the floc size distribution responds to changing environmental factors of turbulent energy, sediment concentration, and changes in base water composition and salinity during summer and winter. We also compare observations from the tank experiments to in situ observations. Turbulence shear rate, a measure of river hydrodynamic energy, was found to be the most influential factor in determining mud floc size. All flocs produced at a given shear rate could be kept in suspension down to shear rates of approximately 20 s−1. At this shear rate, flocs on the order of 150–200 μm and larger can settle out. Equilibrium floc size was not found to depend on sediment concentration; flocs larger than 100 μm formed in sediment concentrations as low as 20 mgL−1. An increase in salinity generated by adding salts to river water suspensions did not increase the flocculation rate or equilibrium size. However, the addition of water collected from the Gulf of Mexico to river-water suspensions did enhance the flocculation rate and the equilibrium sizes. We speculate that the effects of Gulf of Mexico water originate from its biomatter content rather than its ion composition. Floc sizes in the mixing tanks were comparable to those from the field for similar estimated turbulent energy. Flocs were found to break within minutes under increased turbulence but can take hours to grow under conditions of reduced shear in freshwater settings. Growth was faster with the addition of Gulf of Mexico water. Overall, the experiments provide information on how suspended mud in the lower reaches of the Mississippi might respond to changes in turbulence and salinity moving from the fluvial to marine setting through natural distributary channels or man-made diversions.

Can crop production intensification through irrigation be sustainable? An ex-ante impact study of the south-central coastal zone of Bangladesh

In Bangladesh’s south-central coastal zone, there is considerable potential to intensify crop production by growing dry winter season ‘Boro’ rice, maize, wheat, pulses and oilseeds using irrigation from southward flowing and predominantly freshwater rivers. However, the impacts of surface water withdrawal for sustained irrigation and its safe operating space remain unclear. We used field measurements and simulation modeling to investigate the effects of irrigation water withdrawal for Boro rice–the most water-consumptive crop–on river water flow and salinity under different climate change and river flow scenarios. Under the baseline conditions, about 250,000 ha could potentially be irrigated with river water that has salinity levels below 2 dS/m. The impact on river water salinity would be minimal, and only between 0.71 to 1.12% of the cropland would shift from the 0–2 dS/m class to higher salinity levels. Similarly, for the moderate climate change scenario (RCP 4.5) that forecasts a sea level rise of 22 cm in 2050, there would be a minor change in water flow and salinity. Only under the extreme climate change scenario (RCP 8.5), resulting in a sea level rise of 43 cm by 2050 and low flow conditions that are exceeded in 90% of the cases, the 2 dS/m isohaline would move landward by 64 to 105 km in March and April for the Tentulia and Buriswar Rivers. This would expose an additional 36.6% of potentially irrigable cropland to salinity levels of 2 to 4 dS/m. However, Boro rice will already be well established by that time and can tolerate greater levels of salinity. We conclude that there is considerable scope to expand irrigated crop production without negatively exposing the cropland and rivers to detrimental salinization levels while preserving the ecosystem services of the rivers.

Salt Lake Aerosol Overview: Emissions, Chemical Composition and Health Impacts under the Changing Climate

Salt Lakes, having a salt concentration higher than that of seawater and hosting unique extremophiles, are predominantly located in drought-prone zones worldwide, accumulating diverse salts and continuously emitting salt dust or aerosols. However, knowledge on emission, chemical composition, and health impacts of Salt Lake aerosols under climate change is scarce. This review delves into the intricate dynamics of Salt Lake aerosols in the context of climate change, pointing out that, as global warming develops and weather patterns shift, Salt Lakes undergo notable changes in water levels, salinity, and overall hydrological balance, leading to a significant alteration of Salt Lake aerosols in generation and emission patterns, physicochemical characteristics, and transportation. Linked to rising temperatures and intensified evaporation, a marked increase will occur in aerosol emissions from breaking waves on the Salt Lake surface and in saline dust emission from dry lakebeds. The hygroscopic nature of these aerosols, coupled with the emission of sulfate aerosols, will impart light-scattering properties and a cooling effect. The rising temperature and wind speed; increase in extreme weather in regard to the number of events; and blooms of aquatic microorganisms, phytoplankton, and artemia salina in and around Salt Lakes, will lead to the release of more organic substances or biogenic compounds, which contribute to the alteration of saline aerosols in regard to their quantitative and chemical composition. Although the inhalation of saline aerosols from Salt Lakes and fine salt particles suspended in the air due to salt dust storms raises potential health concerns, particularly causing respiratory and cardiovascular disease and leading to eye and skin discomfort, rock salt aerosol therapy is proved to be a good treatment and rehabilitation method for the prevention and treatment of pneumoconiosis and chronic obstructive pulmonary disease (COPD). It is implied that the Salt Lake aerosols, at a certain exposure concentration, likely can delay the pathogenesis of silicosis by regulating oxidative stress and reducing interstitial fibrosis of the lungs. It emphasizes the interconnectedness of climate changes, chemical composition, and health aspects, advocating for a comprehensive and practical approach to address the challenges faced by Salt Lake aerosols in an ever-changing global climate.
