“…The majority of these studies have focused on Superfund sites (www.epa.gov/superfund), seasonal wetlands, landfills, mining operations, sludge disposal sites, or other sites that are all heavily contaminated. Several authors have documented the importance of small mammals as an intermediate step in the transfer of toxic contaminants to higher tropic levels, and hence important implications regarding the potential bioaccumulation of contaminants can be drawn from small mammal studies (Taylor et al, 1981;Anderson et al, 1982;Hunter et al, 1987;Brueske and Barrett, 1991;Brewer and Barrett, 1995;Kaplan et al, 1996;Laurinolli and Bendell-Young, 1996).…”
