En produisant un peu plus de 158 000 tonnes de nickel (Ni) par an la Nouvelle-Calédonie fait partie des producteurs de Ni les plus importants au monde avec des sols riches en éléments traces métalliques. Cette exploitation massive de Ni est un enjeu économique majeur pour le pays (8 à 17 % du PIB annuel) au détriment de potentiels impacts environne...
peer reviewed / Rotifers are ubiquitous aquatic organisms which form one of the most populous zooplankton classes. Their efficient grazing of phytoplankton and high reproduction and turnover rates enable rapid nutrient cycling which feeds the upper levels of the food chain, making them a vital element of aquatic ecosystems. Furthermore, their small...
In agricultural areas, ponds are suitable wetland environments to dissipate and reduce the occurrence of pesticides in aquatic environments. However, their impact at a catchment scale is still poorly understood. This study aims to determine how these organic contaminants were trapped in a pond located in an agricultural critical zone from SW France...
Short-chain chlorinated paraffins (SCCPs) are organic alkane formulations that are released in the environment by industrial processes and electronic waste. They are widely dispersed by wind and water, and therefore have been found in numerous ecosystems and organisms worldwide, where they are not readily biodegradable. This long environmental half...
Graphene-based nanomaterials (GBMs), such as graphene oxide (GO) and reduced graphene oxide (rGO), possess unique properties triggering high expectations for the development of new technological applications and are forecasted to be produced at industrial-scale. This raises the question of potential adverse outcomes on living organisms and especial...
Short-chain chlorinated paraffins (SCCPs) are organic alkanes with numerous industrial applications which are also present in some electronic devices. They are widely dispersed by wind and water, and therefore have been found in aquatic ecosystems worldwide, where they are not readily biodegradable. Organisms may thus be exposed to them in a wide r...
Fiche thématique N°31 du réseau d’écotoxicologie terrestre et aquatique
This thesis concerns the modelling of several environmental fate and (eco)toxicological properties relevant under the European Union Registration, Evaluation, Authorisation and Restriction of Chemical Substances Regulation (REACH, EC No 1907/2006). Statistical models have been generated using state-of-the-art machine learning methods, such Support ...
The origins of water pollution are numerous, they cause alterations due to their high load of dissolved substances, micropollutants and toxic substances. Many studies have focused on the implementation of remediation measures for these types of pollution. In this work, the case of rivers subject to accidental pollution and the use of reservoirs for...
This work assesses the potential of nettle (Urtica dioica L.) fibers produced on contaminated lands for composite applications. The nettles studied in this work grew spontaneously and in a prevalent manner in poplar short rotation coppice planted for the phytomanagement of a land contaminated by traces of metals. Results show that the contaminant co...
