ASPA in brief

Global efforts to enhance chemical risk assessment have integrated exposure and hazard assessment models, along with new approach methods (NAMs), but there is still the need for a practical and transparent workflow for robust decision-making. ASPA provides modules for toxicokinetic modeling, hazard identification, exposure assessment, and risk evaluation. Modules can be customized based on the specific problem, ensuring flexibility across different regulatory contexts. Consistency and robustness are key, ensuring that the same data and modules yield consistent conclusions and confidence levels, regardless of the application.
