Supplementary file 4_Chemical exposure and risk in river basins: Bayesian integration of e

A probabilistic modeling framework developed within the ENCORE project assesses chemical risk to aquatic ecosystems at the European watershed level. The 4.1 MB file contains a pilot study using a subset of pesticides in Belgium to test a Bayesian network that integrates process-based simulation data with monitoring data from the Waterbase Water Quality dataset. This proof-of-concept, authored by Sophie Mentzel and last updated in May 2026, aims to identify high-risk chemicals by accounting for spatial and temporal exposure patterns.

Use Cases

• Developing Bayesian network models for chemical risk assessment based on the described probabilistic framework.
• Updating prior exposure probabilities from simulations with monitoring evidence based on the described Bayesian updating workflow.
• Identifying chemicals with high contribution to risk in watersheds based on the described spatial and temporal exposure patterns.
• Conducting pilot studies for large-scale European environmental risk modeling based on the described proof-of-concept approach.

Strengths

• Integrates multiple information sources, including the pan-European Waterbase Water Quality dataset.
• Applies a Bayesian updating method to improve risk calculation accuracy, as described in the methodology.
• Released under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The 4.1 MB file size suggests a relatively small dataset, potentially limiting scope.
• Data is contained in a DOCX file, which may require extraction or conversion for analysis.
