Simultaneous preservation of the DNA quality, the community composition and the density of freshwater oligochaetes for the development of genetically based biological indices

Introduction. Oligochaetes are recognized as valuable bioindicators of sediment quality in streams and lakes. The development of an oligochaete index based on the identification of specimens using DNA barcodes requires a method for simultaneously preservin ...

Pesticides drive risk of micropollutants in wastewater-impacted streams during low flow conditions

Juliane Hollender

Micropollutants enter surface waters through various pathways, of which wastewater treatment plants (WWTPs) are a major source. The large diversity of micropollutants and their many modes of toxic action pose a challenge for assessing environmental risks. ...

Spatial distribution and biological effects of trace metals (Cu, Zn, Pb, Cd) and organic micropollutants (PCBs, PAHs) in mussels Mytilus galloprovincialis along the Algerian west coast

Dominique Grandjean, Luiz Felippe De Alencastro

Native mussels Mytilus galloprovincialis are used as bioindicator organisms to assess the concentration levels and toxic effects of persistent chemicals, polychlorobiphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and heavy metals using biomarker ...

Air pollution risk assessment on urban agriculture

Theoretical part (about 3 weeks from 20 Feb to 12 March) Literature search for current knowledge on air pollution in relation to urban farming: where is the accumulation; what kind of pollution can we find (dusts, dioxins, PM, heavy metalsâŠ); what are ...

The influence of particles on bioavailability and toxicity of pesticides in surface water

Environmental risk assessment is an essential part of the approval process for pesticides. Exposure concentrations are compared with ecotoxicological data obtained from standardized laboratory studies and, if available, from field studies to determine the ...

Micropollutant-induced tolerance of in situ periphyton: Establishing causality in wastewater-impacted streams

Juliane Hollender, Ahmed Tlili, Renata Behra

The overarching aim of this field study was to examine causal links between in-situ exposure to complex mixtures of micropollutants from wastewater treatment plants and effects on freshwater microbial communities in the receiving streams. To reach this goa ...

Silver nanoparticle effects on simple stream food webs and ecosystem processes

Carmen Omayra Gil Allué

With the global nanotechnology market growing rapidly, nanomaterials are being increasingly released into aquatic environments, where they can undergo modifications and sedimentation, which will put benthic organisms at risk. Of particular interest is the ...

Direct determination of niobium at the low nanogram level in mineral waters and freshwaters

Michaël Bensimon, Montserrat Filella, David-Julien Magnenat

The increasing use of elements such as Nb and Ta in green and information technologies makes it necessary to develop appropriate analytical methods for studying their environmental and ecotoxicological behaviour. This paper describes the first time Nb has ...
