The present study assessed the relative risk of 29 chemical contaminants to aquatic wildlife in the Bohai region and the Yangtze and Pearl Rivers of China. River monitoring data from 2010 to 2015 for metals, pesticides, plasticizers, surfactants, polyaromatic hydrocarbons, flame retardants, and ammonia were collected. For each chemical, ecotoxicity data were compiled for Chinese-relevant aquatic species. The chemicals were ranked by relative risk either by comparing the ratios of the median river concentration divided by the median ecotoxicity concentration or by the percentage of river measurements which exceeded the lower 10th percentile ecotoxicity value. To provide context, these results were compared with the same analysis for rivers in the United Kingdom. From this collection of chemicals in Chinese rivers, the highest risks appear to be from Cu, closely followed by Zn, Fe, and Ni together with linear alkyl benzene sulfonate, nonylphenol, and NH . This risk, particularly from the metals, can be several times higher than that experienced in UK rivers when using the same analysis. Ammonia median concentrations were notably higher in the Pearl and Yangtze than in UK rivers. The results suggest that China should focus on controlling metal contamination to protect its aquatic wildlife. Environ Toxicol Chem 2018;37:1115-1121. © 2017 SETAC.

“…Perfluorinated compounds (PFCs) make up a group of widely used organofluorine chemicals with fluorine replacing all of the hydrogen atoms on the carbon chain . Previous studies indicate that PFCs pose considerable threats to the natural environment and human health due to their wide distribution, extraordinary persistence, bioaccumulation properties, and potential toxicities. , Perfluorooctanoic acid (PFOA) is the most common PFC present in the environment and is detected in different environmental and biological matrices. , What’s worse, the concentration of PFOA was reported to reach a level of nanograms per liter in some natural waters, and a high concentration level of milligrams per liter was recorded in groundwater . Currently, PFCs are regarded as the most intractable organic pollutants because of the strong C–F bonds, which can endure most conventional chemical and biotic approaches …”

Fe³⁺ Promoted the Photocatalytic Defluorination of Perfluorooctanoic Acid (PFOA) over In₂O₃

In this study, four kinds of In 2 O 3 photocatalysts were prepared by a facile calcination process at different temperatures and used for the removal of perfluorooctanoic acid (PFOA) from contaminated water. Lower calcination temperatures induce higher oxygen vacancy concentrations and larger specific surface areas, thus improving the PFOA degradation performance of In 2 O 3 . In 2 O 3 prepared at lower temperatures of 300 °C (In 2 O 3 -300) and 400 °C (In 2 O 3 -400) demonstrates better catalytic performance, and 10 mg L −1 PFOA could be completely removed within 4 h, with a defluorination ratio of 35% over In 2 O 3 -300 and 39% over In 2 O 3 -400 in 8 h. Fe 3+ only slightly increased the defluorination ratio of PFOA over In 2 O 3 -400 to 43%. A defluorination ratio of ∼20% over In 2 O 3 -600 was obtained in 8 h, while when Fe 3+ was added to the photocatalytic systems, a higher defluorination ratio of ∼60% was obtained in the In 2 O 3 -600 system. Combining diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and in situ DRIFTS to track the decomposition of PFOA, we speculated that Fe 3+ participated in the coordination between PFOA and In 2 O 3 -600, thus promoting the defluorination of PFOA.

An integrated hydrological-hydraulic model employing the 2-D local inertial equation as the core is established for effective numerical simulation of surface water flows in a great lake and its floodplain. The model is a cascade of validated hydrological and hydraulic sub-models. The model was applied to simulating the surface water flows of the Tonle Sap Lake and its floodplain in Cambodia using the roughness coefficient value calibrated comparing with a remote-sensing data set. The resulting model reasonably handles backwater flows during the rainy season and simulates the propagations of wet and dry interfaces without numerical instability, owing to a proper setting of time step supported by a novel numerical stability analysis. Sensitivity analysis of the surface water dynamics focusing on the setting of roughness coefficient and the backwater effect was also carried out. Overall, utilizing the 2-D local inertial equation in the assessment of lake water dynamics is a new modelling approach, which turns out to be an efficient simulation tool.
