Together with multiple partner institutions, GhEnToxLab has recently been awarded a significant research grant via the BELSPO BRAIN.BE program to develop “New Strategies for monitoring and risk assessment of Hazardous chemicals in the marine Environment with Passive Samplers” (see the NEWSTHEPS website for more information). Briefly, the project aims to develop innovative approaches and novel practical techniques that address the current fundamental scientific and methodological issues related to the implementation of Good Environmental Status (GES) of the Marine Strategy Framework Directive in national and European waters.

Last February, Prof. Janssen together with eleven Ph.D. lab members and 2 M.Sc. thesis students participated in the 15th edition of the Flanders Marine Institute (VLIZ) Young Marine Scientists’ day.  In this event, which was attended by 347 ‘young’ scientists’, our colleagues Lisbeth Van Cauwenberghe and Maarten De Rijcke were selected (out of 130 applicants) to give a pitch presentation. Lisbeth confronted the audience with her new results on man’s daily contribution to the marine microplastic problem and Maarten presented his research on the combined effects of temperature and nutrient load on the development of harmful algal blooms.

We investigated the effects of a binary Ni-Zn mixture on chronic reproductive toxicity to the water flea Daphnia magna. The results suggested that the type of interactive effect is dependent on the effect size at which Ni and Zn are combined in the mixture. Weak antagonistic or non-interactive effects occurred in the mixture treatments where each of the individual metals produced insignificant or only weak adverse effects on their own. Conversely, synergistic mixture effects, i.e., stronger effects than expected, only occurred when at least one of both metals in the mixture caused a greater than 20% effect on reproduction. Since low effect sizes are the most relevant ones in most regulatory frameworks, our data suggest that the CA and IA mixture toxicity models can both serve as conservative models for predicting effects of Ni-Zn mixtures.

March 14 through 19, 2015: our colleague Olivier Berteloot attended the SETAC YES conference at the Petnica Science Center in Serbia. Olivier presented his recent research on ‘the influence diet quality on the chronic toxicity of copper to the freshwater snail Lymnaea stagnalis’. He demonstrated that L. stagnalis individiuals fed with lettuce were significantly more sensitive to copper in comparison with fish flake fed L. stagnalis individuals, thus confirming the importance of standardized culture and test protocols for (regulatory) toxicity testing.

VeerleSylvieVeerle Lambert and Sylvie Bauwens were nominated for their extraordinary work coordinating the Centre for Environmental Science and Technology (website CES&T). Through their passion and efforts, they have made it to the short list for the Hermes award for Science and Social Service. Irrespective of the outcome, heartfelt congratulations to Veerle and Sylvie from all of us at GhEnToxLab.

ZeeambGhEnToxLab-member, Maarten De Rijcke, has joined the expert group of ambassadors of sea research. These ambassadors communicate regularly the on the marine scientific research that's being conducted aboard the RV Simon Stevin. Using social media, the Flanders Marine Institute aims to improve the accessibility of marine research to the general public.GhEnToxLab supports this initiative full-heartedly. Today, our research on harmful algal blooms was featured on the facebook page of the RV Simon Stevin (dutch).

Despite the growing evidence that organisms modulate their tolerance towards stressors across subsequent generations, most Ecological Risk Assessment approaches fail to assess the impact of chemicals beyond a single generation.

lisbethThis French documentary (airing October 7th, 22h55, France 2) investigates our plastic consumption and it's consequences. We're addicted to the stuff, but the biggest victim of our consumerism is the sea. Our seas and oceans are littered with tonnes of plastic, some of it so small it is invisible to the naked eye. These microplastics can be so small they are readily ingested by organisms at the base of the food chain. But, with this fact, new questions arise. Did plastics enter our food chain? Do we ingest them as well? Are we contaminated by the plastics that are so ubiquitously present in our daily life? This documentary will answer these questions and more, based on the research performed at GhEnToxLab. For more information click here

etc cover thumb100 Recently a harmful algae bloom made Lake Erie's water temporarily undrinkable in Toledo and surrounding towns in northwest Ohio. Over the last 50 years harmful algal blooms have been a regular occurrence in Lake Erie, with peak concentrations in late summer months. Such harmful algal blooms are commonly produced by cyanobacteria and not only impact water quality but they also have the potential to produce toxins that can harm humans, pets and wildlife. The blooms are caused by a combination of factors that promote high densities and reproduction of algae, one major factor being warmer temperatures. Therefore climate change has been linked to the global expansion of cyanobacteria through changes in temperature.
