5 Results of screening of compounds

Survey and Health Assessment of Possible Health Hazardous Compounds in Proofing Sprays

5.1 Results of the chemical screening

The selected products were examined to find out which substances they contain in order to assess if they consist of health hazardous substances that require closer investigation through quantitative analyses. All products were analysed quantitatively with regard to aerosol liberation and size distribution and the results are shown in chapter 6: Results of quantitative analyses and aerosol analyses.

5.1 Results of the chemical screening

The substances that were identified in connection with the effectuated screenings are summed up in the following tables. They are divided according to analysis method.

5.1.1 Results before x-ray measurements

Table 5.1 states the results of the fluorine and silicium analysis. The content of silicium in product no. 6, 8, 9, 14, 15 and 16 might be an expression of a background value from the used fabric on which the proofing product was applied. The results are based on the condition that the samples are homogeneous, meaning that the product was applied in a uniform layer on the fabric.

5.1.2 Results of the SPME-GC/MS screening

Table 5.3 shows the results of the SPME-GC/MS screening that was carried out. The identified substances are marked with ”X”. The substances are shown according to their retention time which is an expression for their boiling point and thus their ability to evaporate. Therefore, substances with the lowest boiling point are stated first in the table. All identified substances are stated with a CAS no.

Volatile organic compounds were not identified in product no. 4 and 24 of this analysis method.
