Since the early 1920s, the intensive use of antibiotics has led to the contamination of the
aquatic environment through diffuse sources and wastewater effluents. The antibiotics …

Contaminant-related stress on aquatic biota is difficult to assess when lethal impacts are not
observed. Diatoms, by displaying deformities (teratologies) in their valves, have the potential …

The effects of the herbicide Diuron (DIU) and the bactericide Triclosan (TCS) were assessed
on laboratory-grown stream biofilms. Four week-old biofilms were exposed in mesocosms to …

The aim of this chapter is to highlight the importance of microbial attached communities in
the assessment of the effects of pollutants on freshwater ecosystems. We particularly focus …

Complexity of contaminants exposure needs to be taking in account for an appropriate
evaluation of risks related to mixtures of pesticides released in the ecosystems. Toxicity …

Untargeted metabolomics is a non-a priori analysis of biomolecules that characterizes the
metabolome variations induced by short-and long-term exposures to stressors. Even if the …

Polar organic chemical integrative samplers (POCIS) are valuable tools in passive sampling
methods for monitoring polar organic pesticides in freshwaters. Pesticides extracted from the …

Interactions between emerging contaminants and other drivers of community structure and
function are poorly known. We used laboratory microcosms to investigate the single and …

Many recent ecotoxicological studies suggest a relationship between freshwater
contamination and increasing abundances of motile diatoms (potentially able to move). The …

Few ecotoxicity studies are available on thorium (Th) which hinders the ability to evaluate its
ecotoxicological risk. Its release in the environment is often associated with the extraction of …
