Heavy metal concentrations in Enchytraeidae (Oligochaeta) in the Niepołomice Forest

open access: yesEcotoxicology and Environmental Safety, 2004
Enchytraeidae were investigated as a part of a broad study of Niepolomice Forest ecosystem functioning. Animals were collected in oak-hornbeam (Tilio-Carpinetum) and in mixed oak-pine (Pino-Quercetum) stands. The highest cadmium concentration was observed in oak-hornbeam from the northern part of the forest (32.33+/-23.22 mg kg(-1) dry mass), with ...
