Summary: The study evaluated the effects of wastewater infrastructure construction on regional and local environments in Monroe County, Florida. The most significant factors influencing fecal coliform and enterococci concentrations were rainfall and project period. On a yearly basis, infrastructure projects showed desired effects in reducing FIB levels in the years following construction.

Summary: This study reveals correlations between the location of sampling sites, seasons, physico-chemical parameters of water, and the concentrations and antibiotic resistance of faecal indicator bacteria in the river. Drug-resistant Escherichia coli showed highest concentration in summer at the site at the end of the river, while drug resistance in enterococci significantly increased in spring.

Summary: The study used 16S rRNA amplicon sequencing to assess microbial water quality in the Bagmati River in Kathmandu, Nepal, revealing that downstream microbial communities were mainly influenced by untreated sewage. Seasonal variability in the sewage microbiome was reflected in downstream river water quality. The findings suggest that despite near universal basic sanitation provision in Nepal, inadequate wastewater management may pose public health risks by turning urban rivers into open sewers.

Summary: The study demonstrates that adding aqueous ammonia to cattle slurry significantly increases the inactivation rate of Cryptosporidium parvum and reduces the numbers of bacterial indicators. Therefore, ammonia can effectively lower the pathogen concentration in slurry before application to agricultural land.

Summary: Anthropogenic waste streams can be a significant source of antibiotic resistant microbes in the environment, posing a potential risk to public health. A study conducted at a popular swimming beach in Australia found that following significant rainfall, levels of faecal indicator bacteria and antibiotic resistance genes (ARGs) increased significantly, indicating an elevated human health risk. The study also identified stormwater drains as the main points of ARG input, and observed positive correlations between ARGs and certain stormwater drain indicator taxa, including human pathogens.

Summary: This study found that potentially pathogenic bacteria with high aerosolization factors were present in the sea surface microlayer during perigean tides and a sewage spill, indicating increased transfer to the aerosol phase. The exchange of microbes between different reservoirs, particularly the water surface microlayer and aerosols, was evaluated. Results showed an increase in culturable bacteria and potential pathogenic bacteria (Corynebacterium and Vibrio) during perigean tides and the sewage spill, with Corynebacterium, Vibrio, and Staphylococcus being the most abundant genera in aerosol samples.

Summary: Despite the abundance of faecal pathogens in urban environments, the presence of faecal bacteria on city streets has not been quantified. The transfer of faecal pathogens between outdoor and indoor environments is also not well understood. This study found that faecal indicator bacteria were present on interior floor surfaces, shoe soles of building occupants, and exterior sidewalks in New York City. The findings suggest that there is ample opportunity for human exposure to faecal pathogens in the indoor environment.

Summary: Fecal indicator bacteria (FIB) are monitored to assess water quality and health risk at beaches, but infrequent monitoring can lead to inaccurate assessments. This study conducted high-frequency FIB sampling at an enclosed harbor in California, showing more variability in FIB concentrations compared to open beach sites. Correlation and regression analyses revealed strong associations between FIB concentrations and chlorophyll a, turbidity, wind speed, and tide level. The study emphasizes the importance of sampling FIB concentrations and environmental parameters at appropriate temporal resolutions for water quality monitoring.

Summary: The presence of cyanobacteria during a harmful algal bloom can significantly affect the survival of Escherichia coli bacteria. This is due to the toxic effect of cyanobacteria-produced microcystins on E. coli. Therefore, the use of E. coli as a fecal indicator bacteria needs to take into consideration the presence of cyanobacteria.

Combined sewer overflow (CSO) was identified as a major factor contributing to the increase in ARGs and related bacterial communities. Pathogenic bacteria like Acinetobacter, Pseudomonas, and Prevotella were found to carry the observed ARGs in the recreational seawater.

Summary: This study investigated the nitrogen assimilation rates of different species within Symbiodiniaceae and identified two groups with contrasting nitrogen acquisition strategies: the affinity-adapted species associated with larger size and higher nitrogen content, and the velocity-adapted species characterized by small size and efficient nitrate assimilation. These findings support the relevance of functional trait-based approaches in describing Symbiodiniaceae diversity and highlight the importance of bottom-up mechanisms in shaping symbiont composition.

Summary: Fish and fishery products are highly traded commodities, but over-exploitation threatens their sustainability. Current monitoring techniques have limitations in assessing fish species. To address this, researchers developed an eDNA-based method to identify fish taxa from effluent water. Results showed that eDNA methods could overcome challenges of visual identification and provide an efficient and accurate market-wide species inventory.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
