Summary: This study investigates the drying preferences of macroinvertebrates in intermittent rivers and ephemeral streams (IRES) and their potential as biomonitoring indicators. The research identifies certain macroinvertebrate groups with drying-resistant niches that can serve as potential indicators in IRES. However, functional traits have limited ability to predict drying specialization. The density, relative abundance, and richness of drying-resistant taxa are less affected by drying intensity compared to drying-sensitive taxa.

Summary: The extensive use of macrolide antibiotics has led to their frequent detection in aquatic environments, affecting water quality and ecological health. This study analyzes the sources, distribution, fate, ecotoxicity, and global risk assessment of macrolide antibiotics based on recent literature. The results show that there are eight main sources of macrolide antibiotics in the water environment, and the most polluted water bodies are wastewater treatment plants and densely inhabited areas. Adsorption, photodegradation, and bioremoval are the main attenuation mechanisms in natural water environments. Macrolide antibiotics have ecotoxic effects on microalgae, crustaceans, fish, and invertebrates, causing oxidative stress and affecting gene expression. Over 50% of reported water bodies represent medium to high risk to microalgae. Further research on antibiotic removal technologies, combined ecotoxicity of antibiotic mixtures, and accurate ecological risk assessment models is encouraged.

Summary: Pesticide occurrence in urban streams is influenced by region and degree of urbanization, with a suite of urban signature pesticides (USPs) consistently detected in small U.S. urban streams. The USPs accounted for the majority of summed maximum pesticide concentrations at urban sites and showed increased complexity and potential toxicity with higher levels of urbanization. Urbanization explained the most variability in pesticide profiles, indicating the importance of monitoring and testing priority pesticide mixtures for potential aquatic toxicity.

Summary: Benthic biofilms in proglacial floodplains are comprised of diverse microbial communities. Our study reveals that certain bacterial clades have high diversity and abundance in different stream types, while others are specific to only one stream type. Additionally, we found that the abundance of these bacterial clades may decrease with future glacier melting.

Summary: Our study revealed that benthic biofilms in glacier-fed streams harbor distinct bacterial communities compared to the suspended bacterial assemblages in the streamwater. Selection processes were found to be shaping the differentiation of these bacterial communities, contrary to expectations given the high vertical mixing of water and bacterial cells in glacier-fed streams. Our research highlights the presence of a microbiome specific to benthic biofilms in glacier-fed streams, which are currently endangered by global warming.

Summary: This review investigates the occurrence of organophosphate esters (OPEs) in aquatic ecosystems and human-related areas over the past decade. It finds that emission source intensity, water chemistry, and organic carbon content play important roles in the partition and transfer processes of OPEs in water. Photodegradation and reductive degradation show potential in improving the removal efficiency of chlorinated OPEs. Overall, most surveyed OPEs pose negligible ecological and health risks, but OPEs with moderate threats or chronic effects on aquatic ecosystems should receive more attention.

Summary: Neonicotinoid mixtures are commonly found in streams worldwide, but their ecological impacts are not well understood. This study shows that exposure to neonicotinoids above certain thresholds can lead to a loss in taxa abundance and richness, disrupted adult emergence, and altered trophodynamics. The presence of neonicotinoid mixtures in California streams also poses greater than expected risks to stream health.

Summary: Conservation efforts aim to enhance pollinator diversity in agroecosystems, but their exposure to pesticides in grassland fields remains poorly understood. This study assessed pesticide exposure using passive samplers and bee tissues in conservation grassland fields. A total of 46 pesticides were detected, with herbicides more prevalent in July and insecticides and fungicides more prevalent in August. Pesticide concentrations in bands increased with cultivated crops. Bee tissues showed consistent detection frequency across months. The results highlight the importance of considering both passive samplers and bee tissues to understand pesticide exposure in conserved grasslands.

Summary: The study compares the contributions of different reuse waters (wastewater effluent, urban stormwater, and agricultural runoff) to surface water contamination, revealing substantial organic-chemical contributions from each source. Episodic storm-event organic concentrations and loads from urban stormwater are comparable to and sometimes exceed those of daily wastewater effluent discharges. The study also assesses the impact of wastewater-effluent irrigation on organic-chemical concentrations in rain-induced agricultural runoff and harvested feedstock, finding minimal differences except for two specific organic substances in effluent-irrigated corn.

Summary: Naled, an organophosphate insecticide, is aerially applied for mosquito control over aquatic ecosystems near Sacramento, California, USA during summer. Samples from rice fields and a flowing canal in 2020 and 2021 were analyzed for Naled and dichlorvos concentrations. The maximum concentrations of Naled and dichlorvos detected in water samples one day after application exceeded the U.S. EPA's benchmarks for invertebrates. Both compounds were not detected in water after one day, but dichlorvos was found in crayfish samples up to 10 days after the last application. The compounds were transported downstream of the target area, influenced by factors such as flight paths, dilution, and transport through air and water.

Summary: A pilot study was conducted in eastern Iowa to assess human exposure to neon-icotinoids (NEOs) among farming households. The study found that NEOs were detected in both outdoor and indoor water samples, with clothianidin being the most frequently detected NEO. Human exposure to NEOs was also found in urine samples, with multiple NEOs and metabolites being present. Additionally, the study concluded that while water consumption may contribute to exposure, other factors like diet and occupational exposure may play a bigger role.

Summary: The increasing concentrations of selenium, nitrate + nitrite, and sulfate in the Koocanusa Reservoir and downstream in the Kootenai River are linked to expanding coal mining operations in the Elk River Watershed in Canada. The study found that the Elk River has experienced significant increases in concentration and load of these solutes, while the Kootenay River has only shown small magnitudes of change. The Elk River contributes a significant amount of flow and solutes to the reservoir, highlighting the potential impacts of coal mining activities. The current surface water treatment operations may not be sufficient to meet U.S. water quality standards in the Koocanusa Reservoir.
