Abstract: This paper gives a brief overview of the findings of hexachlorobenzene (HCB) in fireworks compositions observed within EC type-examinations according to Module B (as set out in the annex II of the Directive 2007/23/EC) of the notified body BAM. In this work, roughly 220 samples were analysed, originating from 49 consumer fireworks articles of the category F2, such as batteries, combinations, fountains and rockets. It was found that the vast majority of samples showed concentrations below 5 mg HCB/kg. However, in three cases concentration values between 5 mg HCB/kg and 50 mg HCB/kg were observed, and in a further four cases extreme values of up to 8046 mg HCB/kg were detected . The results of this study are compared with published HCB findings originating from market surveillance activities in Europe.
