Abstract
Abstract
Exposure to environmental pollutants like chemicals or air pollution is major health concern for the human population. Especially the nervous system is a sensitive target for environmental toxins with exposures leading to life stage-dependent neurotoxicity. Developmental and adult neurotoxicity are characterized by specific adverse outcomes ranging from neurodevelopmental disorders to neurodegenerative diseases like Alzheimer’s and Parkinson’s disease. The risk assessment process for human health protection is currently undergoing a paradigm change toward new approach methods that allow mechanism-based toxicity assessment. As a flagship project, an in vitro battery of test methods for developmental neurotoxicity evaluation is currently supported by the Organization for Economic Co-operation and Development (OECD). A plethora of stem cell-based methods including brain spheres and organoids are currently further developed to achieve time- and cost-saving tools for linking MoA-based hazards to adverse health effects observed in humans.
