Summary: Monitoring the levels of total suspended solids (TSS) and settleable solids (SetS) in wastewater is crucial for maintaining water quality parameters. Traditional reference methods for determining TSS and SetS are time-consuming and expensive. To address this issue, researchers developed SWAMVA, a new analytical instrument equipped with a machine vision-based automatic sampler and software for real-time digital movie capture. SWAMVA significantly reduced the analysis volume and time while providing accurate and precise results.

Summary: An in-depth understanding of particle size distribution and total suspended solids (TSS) in surface runoff is crucial for managing urban diffuse pollution. Field experiments and model simulation were used to explore the dynamic behavior of TSS and influencing factors, showing that higher TSS concentrations in surface runoff contained coarser particles washed off from road-deposited sediments. Factors such as rainfall characteristics, urban-rural gradients, surface roughness, and climate differences affect the contribution rate of RDS to TSS by altering particle size composition.

Summary: This study provides a comprehensive review of measurement methods for water quality parameters (WQPs), specifically total dissolved solids (TDS) and total suspended solids (TSS). Conventional methods have limitations in terms of cost, labor, and spatial coverage, while remote sensing (RS) has emerged as an alternative. RS applications using airborne and satellite sensors have shown promise in retrieving TDS and TSS measurements, but challenges such as atmospheric interference and optical properties need to be addressed. Incorporating RS and conventional approaches can effectively detect changes in WQPs and further research should focus on technological advancements for real-time monitoring.

Summary: Accurate assessment of total suspended solids (TSS) is crucial for managing the health of aquatic ecosystems. A remote sensing based algorithm called the Wen algorithm has been developed and used to measure TSS concentration in the Raidak river. The study analyzed three consecutive years (2019, 2020, and 2021) and found that TSS concentration is highest during the monsoon months. The findings also highlight the correlation between sediment flux and rainfall, stream flow, cross-sectional area, and anthropogenic stress in the river.

Summary: Heterotrophic bacterial activity in biofloc systems leads to the accumulation of total suspended solids (TSS), which affects animal health and product quality. However, eliminating TSS causes a sudden change in microbial composition and nutrient concentration, promoting the growth of pathogenic bacteria. In this review, we propose novel management strategies to manipulate TSS levels by controlling heterotrophic and nitrifying bacterial activities. Hybrid activity between these bacteria can decrease bacterial intensity and carbon source supplement in biofloc systems.

Summary: While characterizing urban stormwater runoff as a major pathway of pollutant transport is important, the lack of access to online sensors and infrequent grab sampling has limited the assessment of storm runoff quality in many urban systems. This study investigates whether turbidity and total suspended solids can serve as surrogates for measuring total metals concentration in storm events in highly urbanized catchments, specifically in Tehran City. The study finds robust relationships between total suspended solids and metals concentrations, indicating that total suspended solids can explain variations in total metals concentration in this highly urbanized catchment.

Summary: Microplastic particles (MP) are a growing concern for aquatic ecosystems due to increased plastic manufacture. The transport and dispersion mechanisms of MP in aquatic environments are not well understood. This study investigated the transport of MP under a unidirectional flow in a laboratory setting. The presence of sediment increased the vertical transport of MP to the bottom, with higher sediment concentrations resulting in greater downward flux of MP. The scavenging of MP by sediment particles led to differential settling patterns, potentially increasing the presence of MP near their sources.

Summary: The novel combinations of climatic conditions and prolonged fire seasons caused by climate change have led to an increased occurrence of megafires. These large-scale fires pose an unknown threat to biodiversity due to the increased extent and severity of burn. This study assessed the impacts of the 2019-2020 Australian wildfires on estuarine benthic sediment communities using eDNA techniques, revealing that estuaries from burnt catchments with no buffer showed greater dissimilarities in composition and abundance compared to those with an intact buffer or from unburnt catchments. The changes in sediment community composition and abundance were associated with increased concentrations of nutrients, carbon, including fire-derived pyrogenic carbon, and copper in highly burnt catchments.

Summary: Two virus concentration methods, AE and NMVP, along with extraction kits were used to quantify PMMoV and SARS-CoV-2 in wastewater samples. The results showed that NMVP workflow produced higher PMMoV concentrations in 58% of samples, while AE workflow produced higher SARS-CoV-2 concentrations in 69% of samples. The concentrations of PMMoV were not sensitive to turbidity, but the concentrations of SARS-CoV-2 were strongly correlated with turbidity.

Summary: Estuaries in rainfall poor regions like Coorong, Australia, are facing ecological health decline due to reduced freshwater inflows and increased evapo-concentration. The persistently hyper-saline and hypereutrophic conditions in Coorong are affecting water quality and sediment quality, leading to negative impacts on the ecosystem. Increasing lagoonal flushing would help to reduce hypersalinisation and hypereutrophication and improve the health of the ecosystem.

Summary: The ongoing COVID-19 pandemic has highlighted the importance of wastewater surveillance in monitoring and tracking the spread of infectious diseases, such as SARS-CoV-2. This study used the adsorption-extraction (AE) method with different pore size membranes to determine the concentrations of four types of endogenous viruses in wastewater samples. The results showed that the larger pore size membrane performed comparably to the smaller pore size membrane for virus detection/quantitation. The study provides valuable insights into the application of the AE method for virus recovery from wastewater, which is crucial for monitoring and tracking infectious diseases in communities.

Summary: Marine artificial structures often have negative impacts on native species diversity and promote the presence of non-indigenous species. However, the addition of complex habitat and bioreceptive materials can help mitigate these effects. In this study, the effects of structural complexity and concrete mixture on recruitment were investigated. The results showed that complex tiles had less algal cover, while mixtures with oyster shell supported higher cover of sessile species. The non-indigenous ascidian Styela plicata dominated complex tiles at a low tidal elevation.

Summary: In order to assess the quality of sediments, it is desirable to predict the toxicity risk levels for aquatic organisms based on simple environmental measurements. This study evaluates the improvement in toxicity risk predictions by using bioavailability-modified guidelines, considering factors such as particle size, total organic carbon, and acid volatile sulfide. The results show that incorporating these factors can enhance the accuracy of toxicity risk assessments.
