Abstract:
... In the context of global warming, it is important to understand the drivers controlling river temperature in order to mitigate temperature increases. A modeling approach can be useful for quantifying the respective importance of the different drivers, notably groundwater inputs and riparian shading which are potentially critical for reducing summer temperature. In this study, we use a one-dimensio ...

Abstract:
... The combination of chemical analyses and bioassays allows the identification of potentially mutagenic compounds in different types of samples. Dyes can be considered as emergent contaminants and were detected in waters, under the influence of textile activities. The objective of this study was to evaluate the contribution of 9 azo dyes to the mutagenicity of representative environmental samples. S ...

Abstract:
... During 2015, we studied the temporal patterns of nutrient concentrations and turbidity in water bodies with different degrees of agricultural and urban pressures across Guangzhou and Foshan (China). Data and observations were made by trained citizen scientists and professional researchers. Our study shows that all monitored water bodies, with the exception of Qiandeng Lake and Fengjiang River, had ...

antibodies; aquatic environment; detection limit; estrogenic properties; europium; fluorescent antibody technique; goats; immunoassays; phthalates; physicochemical properties; risk assessment; rivers; teratogenicity; wastewater treatment; water analysis
Abstract:
... Diethyl phthalate (DEP) is an extensively used phthalic acid diester (PAEs) with estrogenic activity and the potential for carcinogenic and teratogenic effects. To monitor trace DEP in environmental waters, a sensitive direct competitive time-resolved fluoroimmunoassay based on magnetic particles (MPs) as solid support was established. For the assay system, the anti-DEP antibody was oriented on th ...

Abstract:
... This study explores diatom community dynamics in a highly modified semi-arid temperate region river system characterised by inconsistent river flow. Various water and sediment environmental variables were assessed using a multi-faceted analysis approach to determine the spatio-temporal drivers of benthic diatom communities in the river system. Overall, the diatom community was generally dominated ...
