Abstract

Flame retardants (FR) are substances added to materials to reduce their ignition and slow down the burning process. This study presents a series of screening data for different types of FRs occurring in the Czech Republic. A total of 80 different samples were taken, from which mostly organophosphates (PFR), polybrominated diphenylethers (PBDE), hexabromocyclododecane (HBCDD), polybrominated biphenyls (PBB), were found. Positive detections of PFR were measured in the following range: TCPP – 47 times (levels 0.2 to 9.9 μg/g for fabrics, clothes, carpets and some isolations, car interiors, 0.85-2.1 μg/g for children toys, 0.12-2.1 μg/g for mattress, 130-370 μg/g for thermocups, 0.034-27 μg/g for polycarbonate sheet, windowsills, and beach shoes), TPP – 33 times (levels 190-690 μg/g in mineral wools, polyurethane foams, polystyrene EPS and IPS, 150-760 μg/g in clothes, 55 ng/g in carpets, 330-970 μg/g in some electronic devices), TnBP – 3 times (levels 5.7 μg/g in PUFs, 0.8 μg/g in PP carpet, 0.098 μg/g in car interior, TDCPP – 6 times (levels 0.044-1.2 μg/g in PUFs, clothes, seatbelts and car interiors). For TCPP, no samples were found which exceeded regulatory levels set to 5 mg/kg. Compared to brominated flame retardants (BFRs) and PFRs, higher concentrations of PFRs were found. In these cases future efforts should therefore be focused towards these compounds rather than BFRs. One alarming result was the presence of both, BFR and PFR, in children’s clothes and PFR in children’s toys.
