Small children had two to three times higher concentrations compared to the mothers. The concentrations of the children was low and not near the levels considered dangerous.
Brominated flame retardants are used in various consumer goods, such as furniture and plastic material, to increase the fire safety. People are exposed to chemicals mainly through food and dust.
Leena Sahlström has in her thesis analyzed blood samples from these women and their 11-15 month-old child. She has also analyzed the dust from the participants’ homes, breast milk samples and a number of representative food samples.
How much brominated flame retardants people got in from food each pond was estimated and compared with the concentrations found in the blood.
– The dust seems to play a major role in the exposure we are exposed to especially true for small children but also the intake of breast milk appear to contribute to the children’s higher levels in the blood. For mothers, the food is more important than the dust that exposure to brominated flame retardants, says Leena Sahlström at Stockholm University, in a press release.
Although the several brominated flame retardants were banned for about ten years ago are still left in the old products in our environment and in the outdoor environment.
In addition, other brominated chemicals, so-called new brominated flame retardants, introduced to the market to replace those that have been banned.
– We were able to demonstrate a Some new brominated flame retardants in household dust and in some food samples, but also in the blood of some of the participants. Therefore, it is important to keep your eyes on these replacement chemicals in the future, says Leena Sahlström.
