Method Evaluation to Measure Persistent Bioaccumulative Toxic Pollutants in Cow Milk

Report Information

It is important to understand the persistent and bioaccumulative toxic (PBT) levels in milk, as milk fat may be one of the highest dietary sources of PBT exposure. Analysis of milk also allows the opportunity to investigate geographic variability, as milk is produced and distributed on a regional scale. The EPA conducted a study of PBTs in milk during 2002, and reported the results seperately in 2003 (Schaum, et al. 2003. A National Survey of Persistent, Bioaccumulative, and Toxic (PBT)Pollutants in the United States Milk Supply. J. Exp. Anal. and Env. Epi. ). This paper focuses on the chemical analysis of a subset of the chemicals addressed in that study: pesticides, polycyclic aromatic hydrocarbons (PAHs), brominated diphenyl ethers (PBDEs), and polychlolinated naphthalenes (PCNs).
