Polychlorinated Biphenyls (PCBs)


Recent findings indicate that susceptible populations (e.g., certain ethnic groups, sport anglers, the elderly, pregnant women, children, fetuses, and nursing infants) continue to be exposed to PCBs via fish and wildlife consumption. Human health studies indicate that 1) reproductive function may be disrupted by exposure to PCBs; 2) neurobehavioral and developmental deficits occur in newborns and continue through school-aged children who had in utero exposure to PCBs; 3) other systemic effects (e.g., effects on the thyroid and immune systems and self-reported liver disease and diabetes) are associated with elevated serum levels of PCBs; and 4) increased cancer risks, e.g., non-Hodgkin's lymphoma, are associated with PCB exposures.

Interstate Technology and Regulatory Council (ITRC). RISK-1, 115 pp, 2005.

Screening values for a specific chemical may vary among states and even among different regions of EPA. The ITRC Risk Team examined and documented the screening values for five specific contaminantsÔ??arsenic, benzo(a)pyrene, lead, polychlorinated biphenyls, and trichloroetheneÔ??that are often identified as drivers for management actions at contaminated sites.

Department of Health and Human Services, Center for Disease Control, Atlanta, GA. NCEH Publication 05-0570, 475 pp, 2005.

This report series provides an ongoing assessment of the U.S. population's exposure to environmental chemicals by measuring the chemicals or their metabolites in human specimens, such as blood or urine. The report coverage includes metals (e.g., mercury), PCBs, dioxins, polycyclic aromatic hydrocarbons, pthalates, and numerous pesticides. The report is designed to allow users to determine public health information in the following areas: (1) which chemicals get into Americans and at what concentrations, (2) prevalence of people with chemical levels above those of chemicals with a known toxicity level, (3) reference ranges that can be used by physicians and scientists to determine whether a person or group has an unusually high exposure, (4) effectiveness of public health efforts to reduce exposure of Americans to specific chemicals, (5) exposure levels among minorities, children, women of childbearing age, or other potentially vulnerable groups, (6) trends in levels of exposure of the population, and (7) priorities for research on human health effects.

von Stackelberg, K., M.A. Williams, and M.S. Johnson.
ESTCP Project ER-200917, 241 pp, 2014

Predictive models are required to evaluate the impact of potential contaminated sediment management alternatives. This project demonstrated at two Army sites the application of a probabilistic, spatially explicit, and dynamic bioaccumulation model, referred to as FishRand. Those results were compared to the currently accepted practice of a deterministic application and a probabilistic but not spatially explicit application. An application was developed for total PCBs, two individual PCB congeners, and three homologue groups at one site, and for DDT, DDE, and DDD at the other site. Since completion of this effort, the model has been updated to provide direct linkage to GIS files. Additional information: FishRand Model; Project Resources.

SERDP Project ER-1552, 184 pp, 2011

Strategies to assess ecological recovery after in situ sediment treatment by activated carbon (AC) amendment were evaluated at Hunters Point, San Francisco Bay, CA. Polyethylene sampling devices and a PCB immunoassay technique were compared and the polyethylene results correlated with those obtained using conventional methods. Further work with thin polyoxymethylene sampling devices demonstrated the utility of this method to measure the vertical pore-water profile in the sediment and how this compares to the AC distribution in sediment cores. Field-related influences on bioaccumulation and the effectiveness of AC amendment were tested with in situ bioassays and passive sampler deployment. A biodynamic model was used to simulate PCB exposure scenarios present at Hunters Point and the reference sites.

PCBRes (PCB Residue Effects)
U.S. EPA, Mid-Continent Ecology Division. June 2009

The PCBRes Database has been developed to assist scientists and risk assessors in correlating PCB and dioxin-like compound residues with toxic effects. The purpose is to develop PCB critical residue values for fish, mammals, and birds, especially for aquatic and aquatic-dependent species. A self-extracting zip file (15.3 MB) contains assorted documentation and plotting templates. The database requires 50 MB space on a PC and Microsoft Access 2003 or higher.

Bohannon, M.E.B. and M.A. Ottinger. Elsevier, Oxford. The Encyclopedia of the Anthropocene 5:207-213(2018) [Abstract]

PCBs have been shown to have multiple deleterious effects in wildlife. This article focuses on how PCBs have entered the environment, the organic and inorganic matrices they move into, the biological effects they have on wildlife and mammalian health, and the main mechanisms of action by which PCBs exert those effects. Two case studies of PCB contamination are considered in this article along with discussion of the effects wrought by PCBs at a cellular and molecular level.
