The concentrations of tris(4-chlorophenyl)methanol (TCP methanol) and the structurally similar compound, tris(4-chlorophenyl)methane (TCP methane) are reported for the first time in human milk at the concentration of 2.0 and 1.6 ng/g milk fat, respectively. This is 2-3 orders of magnitude lower than the detected levels of other organochlorine compounds (OCCs) such as polychlorinated biphenyls and does not, therefore, change previous risk assessments on human milk. No correlation was found between TCP methanol and other OCCs in human milk, which indicates the absence of a common source. For comparison, TCP methanol and TCP methane were analysed in fish from the North Sea and the Mediterranean Sea. Human milk from Northern Europe was found to have slightly higher levels of TCP methanol and TCP methane than human milk from Southern Europe (although statistically insignificant). This may be explained by the higher levels of these compounds in fish of the Northern European diet.
