Since Health Canada’s PSL testing, a study was published in Environmental Science and Technology (http://pubs.acs.org/doi/full/10.1021/es2007462) in May 2011 in which TCEP was identified in 17 out of 101 PUF children’s products tested. The products identified as containing TCEP included sleep positioners, nursing pillows, portable mattresses and baby carriers. The concentration range of TCEP was 1 080–5 940 mg/kg with a mean concentration of 5 910 mg/kg.
