“…However, the cholesterol concentrations in PGDP females were similar or lower than values reported in the literature [32,33]. Montz et al [8] found that cholesterol concentrations were decreased in PCBexposed raccoons. Increases in serum cholesterol have been associated with exposure to dioxins [34], compounds that have a similar mechanism of action as 3-methylcholanthrene-type inducing PCBs.…”

“…Raccoons were weighed (Ϯ0.10 kg) while in a squeeze cage with a spring scale and then injected with a mixture of ketamine hydrochloride (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) mg/kg body wt; Vedco, St. Joseph, MO, USA) and xylazine (2 mg/kg; Vedco). Artificial Tears lubricant eye ointment (Vedco) was applied to the eyes of sedated raccoons and breathing and heart rate monitored throughout the ensuing procedures.…”

“…Raccoons also represent a useful sentinel of contaminant exposure due to their extensive utilization of riparian habitats and their consumption of a wide variety of food items, each having potential for exposure and subsequent bioaccumulation of contaminants [4][5][6][7][8]. Bigler et al [9] stated, ''The raccoon bridges the gap between avian, terrestrial, and aquatic environs to serve as an effective indicator of many diseases and environmental contaminants'' (p. 596).…”

An investigation involving raccoons (Procyon lotor) as a sentinel species at the Paducah Gaseous Diffusion Plant (PGDP) in Western Kentucky (USA) delineated the extent of exposure to polychlorinated biphenyls (PCBs) and PCB spatial distribution. Raccoon exposure to PCBs was demonstrated through analysis of subcutaneous fat, abdominal fat, liver, and brain tissues from raccoons collected at the PGDP but also was clearly evident in raccoons from a reference area situated along the Ohio River (USA). Raccoons with the highest tissue PCB concentrations appeared to be those inhabiting areas nearest the plant itself and most likely those that ventured into the plants interior. Male raccoons at the PGDP had similar concentrations of total PCBs in subcutaneous fat (1.86 +/- 0.64 microg/g) as males from the reference site (1.41 +/- 0.35 microg/g), but females had higher PCB body burdens than those at the reference site (9.90 +/- 6.13 microg/g vs 0.75 +/- 0.40 microg/g). Gross measurements of exposure to radiation-producing materials revealed that counts per minute exceeded background in 61% of PGDP raccoons compared with 27% at the reference site and five raccoons at the PGDP had beta counts that were more than twice the background. Differences among trapping success, growth rates, and serum chemistry parameters were noted but may have been related to habitat and other environmental and population density factors.
