Ecotoxicological evaluation of area 9 landfill at Crab Orchard National Wildlife Refuge: Biological impact and residues
Polychlorinated biphenyls (PCBs) and lead were investigated in soil and biota at Crab Orchard National Wildlife Refuge (CONWR) and related to biological effects. PCBs were rapidly mobilized from the soil into the terrestrial food chain as evidenced by high residue levels in adult beetles, caged house crickets, and white-footed mice. Bioaccumulation of lead was not observed in invertebrates, but was observed in white-footed mice. Invertebrate abundance and biomarkers were evaluated for signs of toxic response to soil contaminants. The control site and the Area 9 Landfill did not differ in abundance of five common terrestrial invertebrate families. The absence of detectable biological effects in invertebrates shows that these animals can tolerate relatively high environmental concentrations of these contaminants. The intensive use of Area 9 Landfill by invertebrates and their apparent tolerance of soil contaminants eludes to the importance of chemical transfer to higher trophic levels, especially for PCBs.
