This study introduces a data analysis method using partially ordered sets to identify hazardous chemicals, specifically Persistent Organic Pollutants (POPs), in breast milk samples. The approach helps distinguish between more and less dangerous substances for sustainable chemistry applications.
Area of Science:
- Environmental Chemistry
- Green Chemistry
- Chemometrics
Background:
- Sustainable/Green Chemistry aims to reduce hazardous substances in products and processes.
- Persistent Organic Pollutants (POPs) pose significant risks to environment and human health.
- Chemometrics provides criteria for assessing chemical hazards.
Purpose of the Study:
- To analyze data on Persistent Organic Pollutants (POPs) in breast milk samples from Denmark, Finland, and Turkey.
- To identify hazardous chemicals and detect potential differences in POP levels among nations.
- To evaluate a novel data analysis method based on partially ordered sets for chemical hazard assessment.
Main Methods:
- Utilized data analysis based on the theory of partially ordered sets for generalized ranking.
- Investigated datasets of breast milk samples containing measurable levels of 20 POPs.
- Employed the free software package PyHasse for data analysis.
Main Results:
- Successfully applied the data analysis method to distinguish between more and less dangerous chemicals.
- Identified hazardous chemicals within the analyzed breast milk samples.
- Provided a generalized ranking of chemical hazards based on the data.
Conclusions:
- The data analysis method is effective for distinguishing chemical hazards.
- The approach can be applied in sustainable chemistry to identify more and less sustainable chemicals.
- Findings support the use of this method for environmental and human health risk assessment.

Analysis Methods of Pharmacokinetic Data: Model and Model-Independent Approaches
The model approach uses mathematical models to describe changes in drug concentration over time. Pharmacokinetic models help characterize drug behavior in patients, predict drug concentration in the body fluids, calculate optimum dosage regimens, and evaluate the risk of toxicity. However, ensuring that the model fits the experimental data accurately...
