IUPAC Projects

Global Use of the C-NPU Concept System for Properties in Toxicology

The objective of this project is to work out properties and units for global use of the C-NPU (Committee on Nomenclature, Properties and Units) concept system and syntactic rules for properties in toxicology. The C-NPU, maintained as a joint IFCC- IUPAC activity for two decades, has as its main task to promote and maintain scientifically and conceptually sound ways of expressing the outcome of measurements and other examinations in laboratory medicine. The NPU coding scheme and vocabulary, based on the SI system, concepts theory, and high-level international standards, is the main outcome and should be the cornerstone for expressing measurements within international communication standards.

During the first meeting (3-4 August 2002), a first draft by J. H. Duffus was discussed that involved properties in toxicology based on the general structure elaborated by C-NPU. The C-NPU concept system was proven to be appropriate for that purpose as demonstrated by a large number of typical examples. For the next meeting (5-6 December 2002), a draft comprehensive list will be prepared for discussion and after corrections it will be distributed for comments among appropriate organizations and individual specialists.
