6.1 Background for selection of substances

At the initial survey 17 substances were identified in the pigment group (including two intermediate products), two substances in the group of binders and their residual monomers and 22 substances in the group of additives. Among these substances which both has been identified based on general information about content in glass and porcelain colours and concrete information about the test products only 3 substances have been found in connection with the chemical analyses. In this connection it should be underlined that the screening analyses do not specify all substances. A number of substances are grouped under the designations alkanes, alkenes, alcohols, cycloalkanes/-alkenes, glycols and oxy compounds, aromatic compounds and other unidentified substances. Many of the substances found during the survey must be assumed to be covered by these unit designations. This also applies for the additives which are identified in the survey and shown in Table 6.1. The survey also includes a number of pigments which you would not expect to find at screening analysis of only 10 products.

Based on the results from the survey and the chemical analysis of the test products, DEPA has selected a number of test products which should be assessed in view of their health and environmental profile. For these 10 substances a toxicological profile has been elaborated based on available literature.

At the selection the concentration of the substances has been considered and existing knowledge on/or assessments of the substances in connection with consumer products. The selected substances thus represent substances that are found in the highest concentrations in the test products and the substances which DEPA requested to be analysed.

6.2 Selected substances

Table 6.1 gives an overview of selected substances to be assessed for health and environmental properties:

6.3 Data search

Data for the substances' physical-chemical properties were collected from a number of internet based databases.

  1. Chembank
  2. Chemfinder
  3. Ullmann
  4. NTP
  5. SAX
  6. TOXLINE
  7. MEDLINE
  8. HSDB
  9. IRIS
  10. CCRIS
  11. GENETOX
  12. IUCLID
  13. PHYSPROP
  14. BIODEG
  15. BIOLOG
  16. ECOTOX

There will be a certain overlap between several of these databases. Table 6.2 gives an overview of the result of the data search. The overview shows whether the 14 databases contained data for each substance.

It can be seen from the above that for some substances, only limited data are available in the searched literature.
