Research topics<\/strong><\/p>

Emerging organic contaminants include a large number of substances with various physico-chemical characteristics. Understanding the behaviour of these substances in aquatic environments, particularly those with biological activity (drug residues, endocrine disruptors, etc.), requires approaches currently developed in the laboratory at fine \u00a0mechanical scales.<\/p>

The team’s activities are structured around the following scientific orientations:<\/p>

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 – Understand the bioavailability of emerging organic contaminants for organisms and their effects, considering interaction processes in complex environments,<\/p>

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 – Characterize the mechanisms of transformation these contaminants in the treatment processes and in the environment and identify those that lead to a change in biological activity,<\/p>

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 – Survey emerging molecules: their occurrence, transfer, interactions, exposure patterns and effects ,<\/p>

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 – Acquire knowledge on the metabolome in our species of interest to describe, understand and predict exposure and effect of toxic substances through a metabolomic approach<\/p>

The approach by family is preferred, taking into account transformation products and metabolites of targeted substances for a more comprehensive and accurate assessment of exposure of organisms. In order to relate exposure measurement to individual and population effects, targeted and non-targeted analytical approaches using separative methods hyphenated to mass spectrometry are developed. They allow us to benefit from the sensitivity and specificity required to work on complex matrices. The metabolomic approach allows us to study the exposure and effects of contaminants on aquatic organisms by determining both xenometabolome (parent compounds and biotransformation products) and endometabolome (indirect markers within endogenous metabolites which concentrations may differ from physiological levels following a chemical exposure).<\/p>

The use of treated wastewater for irrigation of agricultural fields also deserves the team attention. Reuse poses the problem of introducing organic contaminants like pharmaceuticals occurring in the wastewater into the terrestrial environment. Beside their accumulation and leaching into the subsoil, potentially harmful contaminants can be taken up by agricultural crops and further biotransformed by the plant’s metabolic enzymes. The current research topic aims to further clarify the processes taking place after irrigation of fields with wastewater with regard to wastewater-borne contaminants degradation and ecotoxicological impact. The fate and effects on crops of an array of pharmaceuticals is evaluated in controlled and real scale experiments (i) assessing the microbial degradation of pharmaceuticals in the rhizoshere, (ii) examining uptake and metabolism of targeted contaminants in plants, (iii) estimating their impact on nitrogen cycling in soil and in plant development (iv) estimating the efficiency of innovative decentralized solar-based wastewater treatment systems\u00a0 for the removal of the most harmful contaminants<\/p>
