摘要
This paper compares the patterns of metal (Pb, Zn, Cd, Cu) accumulation in nine populations of the epigeic earthworm, Lumbricus rubellus, native on metalliferous soils, with the patterns of metal accumulation in batches of L. rubellus sampled from an uncontaminated site and maintained on the nine contaminated soils for 31 days under laboratory conditions. The primary findings were: (1) the Pb, Zn and Cd concentrations in the 'native' worms were significantly higher in most cases than in the 'introduced' worms; (2) multiple regression analyses indicated that the relationships between tissue and soil metal concentrations were similar for 'native' and 'introduced' worms; (3) high soil organic matter content reduced the bioavailability of Pb, but low pH increased Pb bioavailability. It was concluded that, although no phenotypic evidence of metal-tolerant ecotypes was obtained, the exposure of earthworms from uncontaminated soils to contaminated soils under laboratory conditions can provide meaningful integrative data concerning metal bioavailability in soils which, for biomonitoring purposes, often present formidable sampling problems.
