Summary: Microplastics, with lower density than water, are concentrated in the neustonic layer near the water-air interface, potentially causing environmental and public health issues. Biofilm-coated microplastics are more attractive for consumption by aquatic animals, increasing their negative impacts. Studying the microbial life on the surface of microplastic particles is crucial for understanding their role in the environment.

Summary: Avena sativa and Sinapis alba are viable options for phytoremediation of soil contaminated with Cd2+, with Avena sativa showing greater ability to accumulate Cd2+ in the roots. Although cellulose fertilization stimulated microbial proliferation in Cd2+-contaminated soil, it did not mitigate the adverse effects of Cd2+ on bacterial diversity. Core microbiome of the soils included bacteria from the genera Sphingomonas, Sphingobium, Achromobacter, and Pseudomonas.

Summary: The aim of this study was to investigate the effect of using Effective Microorganisms (EM) preparation and incorporating organic matter on the soil microbiological and chemical features. The results showed that applying a higher dose of EM combined with manure and straw increased the abundance of heterotrophic bacteria, actinobacteria, cellulolytic microorganisms, and proteolytic microorganisms. Additionally, the chemical parameters were also highest in the experimental variant with biomass incorporation and EM use.

Summary: Metal contamination and other geochemical alterations disrupt microbial composition and functional activities, leading to disturbances in biogeochemical cycles. This study investigated the distribution of total mercury (THg), methylmercury (MeHg), and trace metals in anthropogenically affected sediment. The microbial communities and functional gene profiles were analyzed to explore their relationship with Hg-methylation and geochemical features. Results showed that THg and MeHg levels increased towards the lower horizons of the sediment cores, while Al, Fe, Mn, and Zn were the major metals present at all depths. The enrichment and contamination indices indicated high concentrations of trace metals in the anthropogenically affected sediment. Various functional genes and dominant microbial taxa were detected, with correlations between major taxa and geochemical variables suggesting the significant impact of sediment geochemistry on microbial communities and biogeochemical cycles. Archaeal methanogens and bacterial phyla Chloroflexi and Firmicutes were also implicated in the enhancement of MeHg levels. Overall, these findings provide insights into the microbial communities involved in Hg-methylation process and other biogeochemical cycles.

Summary: This study evaluated the sorption capacity of biosorbent materials such as nut shells for the removal of multiple potentially toxic elements from contaminated waters. Hazelnut shells showed the highest removal efficiency among the tested materials. The complexity of the matrix and element competition negatively affected the sorption capacity, while increasing the sorbent dose and decreasing the initial concentration improved the removal efficiency.

Summary: This study investigated the effects of environmental factors on soil microbial communities under different levels of Sb-As co-contamination in an antimony mine area. The results showed a wide range of Sb and As contents in soil, with their concentrations affected by the distance to surface runoff. Soil environmental factors significantly influenced the microbial communities, and the interaction among microorganisms, heavy metal distribution, and geochemical factors shaped the microbial community. These findings contribute to a better understanding of the response of soil microorganisms to As-Sb distribution and geochemical factors in arable soils under Sb mining areas.

Summary: This study used shotgun sequencing, metagenomic analysis, and qPCR to evaluate the diversity and abundance of Human Herpesviruses (HHVs) in influent wastewater of an urban treatment plant. All nine types of HHVs were detected, with HHV-8 being the most abundant, possibly linked to the ongoing HIV-AIDS outbreak in Detroit during the sampling period. The approach described in this study can help establish a baseline of community virus secretion for monitoring changes in community health and immunity.

Summary: Wastewater-based epidemiology (WBE) is a useful tool for predicting COVID-19 incidence and providing early warnings. In this study, the relationship between SARS-CoV-2 concentrations in wastewater and COVID-19 incidence in southeastern Michigan was examined. The results showed a strong correlation between the viral concentrations in wastewater and the daily COVID-19 cases, with a potential 5-week lag time. Statistical models were established to predict COVID-19 cases, and the autoregression model with seasonal patterns and vector autoregression model were found to be more effective. Flow parameters had little impact on the correlation, and the optimum models worked well for both normalized and non-normalized data. The study also discussed the factors contributing to the observed lag time and evaluated the impact of the Omicron variant and different sampling methods.

Summary: Wastewater-based epidemiology (WBE) is a useful tool for predicting and investigating the extent of SARS-CoV-2, and this study explores the normalization of SARS-CoV-2 concentrations in wastewater. The findings show that normalizing SARS-CoV-2 concentrations and comparing them with COVID-19 incidences can reduce differences between neighborhoods with different demographics. Monitoring water quality parameters or biomarkers, along with RNA concentrations in wastewater, is suggested for adequate data normalization in areas where detailed information about sewage flows and contributing populations is not available.
