Summary: This study assessed the bioavailability and phytotoxicity of acetochlor to wheat plants. The results showed significant correlations between acetochlor concentrations in soil and in wheat foliage and roots, as well as the IC50 values. Soil organic matter content was found to be the main factor affecting the toxicity of acetochlor in the soil-wheat system.

Summary: Sewage sludge is an inevitable byproduct of wastewater treatment, and reusing it can reduce waste and promote circular economy. However, sludge contains potentially harmful chemicals. This study determined concentrations of various compounds in different sludge treatments, and found that bioassays and sampler extracts detecting contaminants in sludge are complementary tools for chemical analyses in assessing environmental risks.

Summary: This study investigated the distribution of pesticides in two important salmon habitats in the Sacramento River watershed. The results showed that the floodplain had significantly higher concentrations of organochlorines compared to the mainstem Sacramento River, and juvenile fish in the floodplain may be more exposed to organochlorines than fish in the river. Additionally, high flow conditions may exacerbate pesticide exposure for fish and other biota.

Summary: Passive sampling is used to quantify the net partitioning of hydrophobic organic contaminants between porewater and solid phases in contaminated sediments, improving risk management strategies. Direct measurements of porewater (C-free) are the most accurate way to predict adverse effects on biota. A stochastic framework is proposed to map solid-phase concentration (C-total) to estimated C-free by considering variability in passive sampling-derived K-TOC relationships.

Summary: This study explored the use of DGT passive samplers to quantify the methylmercury (MeHg) bioaccumulation potential and inorganic mercury (IHg) methylation potential in freshwater wetlands. The results showed that the vertical distribution of bioavailable MeHg is important for macrofauna food sources, and DGT samplers can predict IHg methylation and MeHg bioaccumulation potentials without explicitly determining IHg and MeHg speciation.

Summary: POCIS is widely used for sampling polar organic substances due to its applicability to a wide range of substances and environments, although its sampling performance may vary depending on exposure conditions. In situ calibration is necessary for accurate estimation of aqueous concentrations, and comparisons with grab sampling show that POCIS-derived data generally align well with traditional methods, indicating the robustness of POCIS for identifying contamination trends in surface waters.

Summary: The pollution state in the German Bight was investigated by determining pollutant concentrations in sediment samples. Polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAH) were measured in the pore water of North Sea sediment. The results showed relatively low contamination levels, but higher contamination near the sediment-dumping site.

Summary: Melamine and related triazines have become a public concern due to their persistence, mobility, and toxicity. A new passive sampling method based on DGT technique was developed and validated in this study to assess environmental exposure and risks of these compounds. The MCX-DGT sampler showed reliable performance in measuring triazines in water samples, indicating its potential as an in situ tool for understanding the occurrence, sources, and fate of these emerging substances in aquatic environments.

Summary: Chemcatcher (TM) (CC) and Polar Organic Chemical Integrative Samplers (POCIS) passive samplers were used to investigate trace organic chemical residues in urban streams of Sydney. The study detected a total of 254 chemicals, including aliphatic compounds, pesticides, phenols, PAHs, sterols, fatty acid methyl esters, pharmaceuticals, and personal care products. The sampling rates ranged from <0.001 to 0.576 L day(-1) depending on the type of sampler and chemical. The deployment duration analysis showed that some chemicals had higher detection rates after four weeks for CC SDB-RPS and three weeks for POCIS Oasis HLB. Rainfall was found to be positively correlated with higher detection rates in both estuarine and freshwater sites.

Summary: Determining the concentration of an environmental pollutant may not accurately assess health risks if the pollutant is not bioavailable. Therefore, methods to determine pollutant bioavailability are more relevant for assessing toxicity. The diffusive gradient in thin films (DGT) technique has been used to measure labile compounds in the environment, with advancements in speciation and bioavailability of metals and metalloids.

Summary: This study used active carbon fibre (ACF) passive sampling and multivariate statistical processing to predict the occurrence of organic compounds (OCs) in groundwater and determine the origins of various anthropogenic activities. The research provides insights into controlling OCs in groundwater and offers a holistic approach for understanding the vulnerability of shallow groundwater to contamination.

Summary: A novel passive sampler technique using Oleic acid-embedded cellulose acetate membranes (OECAMs) was developed to evaluate the bioavailability of epoxiconazole (EPO) to earthworms. The study found a significant linear relationship between EPO concentrations in earthworms and OECAMs, with OECAMs reaching equilibrium for EPO sampling within 2 days. Additionally, EPO concentrations in soil porewater, earthworms, and OECAMs were lower in soils with higher organic matter content, showing good potential for OECAMs as a passive sampler for evaluating EPO bioavailability.

Summary: Little information is available about biofilm microbial communities on the surface of livestock buildings. This study proposes a reproducible coupon-based capture method and complementary ex-situ analysis tools to describe the major features of these communities. The analysis of pig farm building coupons revealed a rapid coverage of biological material and the existence of active metabolic microorganism clusters. High-throughput sequencing showed bacterial diversity profiles in accordance with reported bacteria diversity in pig intestinal ecosystems and revealed differences between materials.

Summary: Skillful streamflow forecasts are crucial for water-related applications, with a growing emphasis on improving initial condition estimates through data assimilation. This study assesses the sensitivity of DA-based IC estimation to various uncertainties and model updates over 232 watersheds in France. The comparison of two ensemble-based techniques shows that accurate routing store estimates benefit the DA-based IC estimation, with the EnKF outperforming the PF in forecasting meteorological uncertainty.

Summary: Constructed wetlands can efficiently remove nitrogen from polluted agricultural run-off, but may produce nitrous oxide (N2O) emissions. This study showed seasonal variations in N2O fluxes in a off-stream CW treating nitrate-rich water, with a strong positive correlation to inlet NO3- concentrations and streamflow. Results indicate complete denitrification with only 9% of potential N2O formation emitted to the atmosphere.

Summary: This study aimed to evaluate the potential toxicity of currently used herbicides in Gammarus fossarum using multi-level biomarkers. The results showed that these herbicides caused increased locomotion and respiration in the crustaceans, as well as disruptions in moulting, antioxidant responses and cell integrity. Statistical analyses identified herbicide clusters likely to trigger common sets of biological responses. These findings demonstrate unexpected toxicological effects of currently used herbicides in non-target wild animals.

Summary: This study aimed to investigate the impact of inconsistencies in commonly available streamflow time series on the efficiency and parameter estimates of rainfall-runoff models. Data from 30 catchments in France from 1998 to 2018 were collected and used for hydrological modeling. The results suggest that common suspicious streamflow data have a limited impact on model efficiency and parameter estimates overall, but can lead to instability and lack of robustness in single catchment studies.
