Kortlægning af kemiske stoffer i forbrugerprodukter 162(a), 2018
In total 16 different bicycle were purchased. The screening analyses showed a small content of both chlorine and phosphorus in a single bicycle helmet (C10). A content of fluorine just above the detection limit of 5 ppm was identified in C6 and C10 as well as a high fluorine con-tent of 92 ppm in C4. Quantitative analyses of certain chlorinated phosphorus-based flame retardants in the pad material in C10 were performed as well as of certain PFASs in bicycle straps on C4, C6 and C10. The results showed that in the pad material in C10, the flame retardants TCPP and TDCP were identified in large amounts and that TIBP, TCEP and TPHP were identified in small amounts. A few PFASs were identified in the strap in C4 in small amounts but no PFASs above the detection limit were identified in the straps from C6 and C10. The results of the migration analyses on the pads inside the bicycle helmet showed that the same chlorinated phosphorus-based flame retardants were identified in the migration liquid as identified at the content analysis carried out on C10 (TCPP TDCP,TIBP, TCEP and TPHP. The results of the migration analyses on the bicycle strap on C4 showed that no PFASs migrate above the detection limit. Looking only at the bicycle helmets, none of the investigated helmets constitutes a health problem with regard to the chemical substances investigated in this report.
