Modified Manometric Test Results for Inherent Biodegradability of Chemicals and Polymers

Philippe Marchal's 2026 study presents a modified manometric test for inherent biodegradability of complex and poorly soluble chemicals. The dataset includes results for chemicals like sodium benzoate and polyhydroxybutyrate, comparing the modified method against OECD 301F and 302B standards. Reference chemicals achieved biodegradation between 78 and 100%, while biodegradable polymers showed levels from 76 to 100%.

Use Cases

• Compare biodegradability assessment methods based on the described manometric and DOC removal tests.
• Evaluate the biodegradability of poorly soluble or adsorptive polymers based on the method described.
• Benchmark new biodegradability test results against the reference chemicals (sodium benzoate, polyhydroxybutyrate) included in the study.

Strengths

• Dataset is associated with a peer-reviewed methodological study comparing results to OECD standards 301F and 302B.
• Includes specific performance metrics, such as 78–100% biodegradation for reference chemicals and 76–100% for biodegradable polymers.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• The dataset is small (936.1 KB) and its specific row count and column structure are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect methodological bias inherent to the specific lab setup and chemicals tested.
