Theoretical environmental disciplines in support of sustainable chemistry.

It has been evident for decades that environmental chemicals pose an enormous risk to the environment as well as to humans. However, this important topic is still underestimated in every part of society. The effects of environmental contaminants on health are a major concern because exposure is associated with a number of diseases, including cancer, diabetes, congenital malformations and infertility. Sustainable Chemistry is a chemical philosophy encouraging the design of products and processes that reduce or eliminate the use and generation of hazardous substances. Sustainability and sustainable development are effectively ethical concepts, expressing desirable outcomes from economic and social decisions. The important matter of principle, therefore, becomes a victim of the desire to set targets and measure progress. In this respect, metrical scientific disciplines like Chemometrics, Environmetrics, Biometrics, Chemoinformatics, Environmental Informatics, etc. are of great importance. The environmetrical data-analysis method applied in this paper is the method of partially ordered sets. Partial order is a discipline of Discrete Mathematics and one may consider partial order as an example of mathematics without numerical arithmetic. The graphical representation of partial orders is laid down in so-called Hasse diagrams. We present the occurrence of Persistent Organic Pollutants (POPs) in breast milk samples. It can be concluded that bioaccumulative chemicals pose a danger to both humans and the environment and that hence much effort should be laid on the development of safer, that is to say biodegradable, chemicals in the future
