California Childhood Leukemia Study (CCLS)
Analysis of flame retardants and other persistent chemicals in blood samples from mothers of children with leukemia and mothers of children without leukemia
The California Childhood Leukemia Study (CCLS) is a population-based case-control study that seeks to identify genetic and environmental risk factors for childhood leukemia. The study is conducted by researchers at the University of California, Berkeley, School of Public Health.
In a sub-study designed to evaluate the relationships between chemicals in house dust and chemicals in children’s and mothers’ blood, Biomonitoring California laboratories have analyzed polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and organochlorine pesticides in serum samples from 48 mothers.
The CCLS is supported in part by the National Institute of Environmental Health Sciences (NIEHS), the National Cancer Institute (NCI), and the US Environmental Protection Agency.
