Metal pollution is a threat for ecosystems worldwide. Environmental quality standards for metals are based on classic lab tests, in which a test organism is exposed to one chemical in constant, favorable conditions. However, in nature chemicals most often occur in mixtures. This could result in synergistic, additive or antagonistic effects. Furthermore, organisms face natural stressors every day: predators, temperature fluctuations, food deprivation,...Thus, more ecologically relevant toxicity tests are essential.
The central aim of my project is to study the effects of the combined exposure to natural stressors and metal mixtures of Cd, Cu and Pb on aquatic invertebrates. Studying the effects of these stressors on individuals as well as the population and community responses will result in a better understanding of the ecotoxicity of metal mixtures in nature. This will eventually lead to the construction of more ecologically-relevant monitoring strategies and environmental quality standards for trace metals.
