Finally, the quality control analysis showed that there were no PCBs present (within detection limits) in any of the samples tested, and that the highest concentration of arsenic measured was 4.9 ppm, thereby confirming that the raw material, the extracts and the collection site were all within safe limits of these compounds.
Að lokum sýndu gæðamælingar (quality control analysis) að engin PCB efni voru í sýnunum í mælanlegum styrk og mesta magn af arseniki mældist 4,9 ppm. Þessar mælingar staðfesta að öll hráefnin og útdrættirnir eru innan þeirra öryggismarka sem sett eru fyrir þessi efni.
