Although seafood is a nutritious protein source, due to marine environmental pollution, seafood may also be a source of contaminants. The results obtained within the FP7-ECsafeSEAFOOD-project show that among the range of studied environmental contaminants certainly methylmercury (MeHg) requires deeper investigation. This paper presents the results ...
Generating aptamers that bind to specific metal ions is challenging because existing aptamer discovery methods typically require chemical labels or modifications that can alter the structure and properties of the ions. In this work, we report an aptamer discovery method that enables us to generate high-quality structure-switching aptamers (SSAs) th...
Diffusive gradient in thin film (DGT) samplers have been widely used as water quality monitoring tools to study cationic trace metals of the Water Framework Directive (WFD) (lead, cadmium, nickel). However, these samplers based on a polyacrylamide diffusive gel and a Chelex resin do not allow trapping methylmercury (MeHg) and inorganic mercury [Hg(...

Interplanetary coronal mass ejections (ICMEs) observed by the MESSENGER and Venus Express spacecraft have been catalogued and analysed. The ICMEs were identified by a relatively smooth rotation of the magnetic field direction consistent with a flux rope structure, coinciding with a relatively enhanced magnetic field strength. A total of 35 ICMEs we...

This article critically evaluates existing causal explanations for the persistence of informality in artisanal and small-scale mining (ASM). These explanations share a legalistic focus on entry barriers and political impediments that prevent or discourage the formalization of poverty-driven ASM operators: however, they fail to fully explain cases s...
Trophic models based on nitrogen stable isotope ratios (d15N) have been shown to predict changes in mercury (Hg) concentrations in fish; however, they are usually applied at the ecosystem scale and are rarely directed at known trophic pathways. We discuss a novel approach in which we combined gut contents analysis and stable isotope analyses (d15N ...
Mercury is a metal naturally and widely present in the environment but human activities have greatly increased its amount in all environmental compartments. This element, under its organic form methylmercury, became a global environmental concern due to its high toxicity, its capacity to bioaccumulate in biota and to biomagnify in the food chain. I...
