In accordance to the EU Commission Regulation 2015/1933 from 27th of October, 2015 the manufacturers of dietary supplements, dried herbs and spices are obliged to examine their products. Content of the polycyclic aromatic hydrocarbons ( PAHs) should be determined. In our laboratory we have launched methodology allowing the study of these substances. Therefore, we invite manufacturers of these product groups to cooperate in the determination of PAHs in their products.
