The European Union System for the Evaluation of Substances (EUSES) software meets many quality standards for chemical risk assessment. However, high complexity and poor documentation require significant improvements for transparency.
Area of Science:
- Environmental Science
- Computational Toxicology
- Software Engineering
Background:
- Chemical risk assessment software requires robust quality standards for reliable results.
- Existing standards (ISO/IEC 12119) provide a foundation but may not cover all specific needs for chemical evaluation programs.
- The European Union System for the Evaluation of Substances (EUSES) is a key tool in this domain.
Purpose of the Study:
- To evaluate the software quality of EUSES 1.00.
- To develop and apply quality criteria for chemical risk assessment software.
- To identify areas for improvement in EUSES.
Main Methods:
- Development of quality criteria based on ISO/IEC 12119, literature, and new requirements.
- Software testing of EUSES 1.00.
- Review of EUSES 1.00 documentation.
Main Results:
- EUSES 1.00 generally meets postulated quality criteria, showing correctness and stability.
- No errors were detected in correctness and stability testing.
- Identified areas for improvement include high complexity, low modularity, and incomplete documentation, impacting transparency.
Conclusions:
- EUSES 1.00 is a modern software product that fulfills many quality criteria for chemical risk assessment.
- Significant alterations are needed to address complexity, modularity, and documentation gaps.
- The developed quality criteria can guide future development of similar risk assessment software.
