Supplementary file 3_Chemical exposure and risk in river basins: Bayesian integration of e

Sophie Mentzel's supplementary file from the ENCORE project details a probabilistic framework for assessing chemical risk to aquatic ecosystems at the European watershed level. The 1.4 MB PDF, last updated in May 2026, describes a Bayesian network model that integrates process-based simulation data with monitoring data from the European Environment Agency's Waterbase Water Quality dataset. A pilot study focusing on a subset of pesticides in Belgium serves as a proof-of-concept for this risk modeling approach.

Use Cases

• Developing Bayesian network models for environmental risk assessment based on the described probabilistic framework.
• Updating prior exposure probabilities with monitoring data 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.
• Testing probabilistic risk modeling approaches for pesticides based on the described Belgian pilot study.

Strengths

• Framework integrates multiple sources of information, including pan-European Waterbase Water Quality data.
• Describes a specific pilot study using a subset of pesticides in Belgium.
• The PDF file is 1.4 MB in size, indicating a detailed document.

Limitations

• The dataset is a PDF document; the underlying structured data (rows, columns) is unavailable.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• The primary data covers a pilot study in Belgium; European-scale application is described as a future goal.
