“…In Ref. [64], they also demonstrated, both in situ and during exposure in laboratory conditions, the accumulation of PCDDs and PCDFs in E. fetida tissues at concentrations of 1.5-15,000 μg.kg À1 dw, using contaminated soils from Sweden. The accumulation of PCDDs and PCDFs in the tissues of two other earthworm species, Allolobophora caliginosa trapezoides and Lumbricus rubellus, was also observed by [78], and in [77] they reported concentrations of 0.9 μg.kg À1 dw of PCDDs and PCDFs in earthworms taken from rice fields in Japan.…”

The presence of former brominated flame retardants and “emerging” brominated flame retardants (BFRs and e-BFRs) in soils is well documented, but the presence, metabolism and uptake of them in earthworm species are much less. Polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDDs) are the most abundant “legacy” BFRs in soils. Earthworms are a good bioindicator, presenting an integrated view of soil chemical pollution. They bioaccumulate BFRs passively by dermal absorption, and actively through soil ingestion. However, such information is only available for a limited number of species, mostly for Eisenia fetida, which shows high bioaccumulation factors (>2). Most of the ecotoxicity studies on earthworms have been done using PBDEs or HBCDDs. PBDEs were reported to effect changes in enzyme activities, which induced oxidative stress and caused metabolic perturbations in some earthworm species. In E. fetida, contaminant bioaccumulation is influenced by the lipid and protein contents of tissues, but several different processes (uptake, depuration, metabolism and isomerization) also contribute to the observed tissue levels. To evaluate and manage the risks posed by these chemicals to terrestrial ecosystems, it is important to better understand the transfer processes of emerging brominated flame retardants in earthworms, as well as the potential trophic biomagnification.

“…In the same way [63], they investigated the capacity of E. fetida to accumulate doxin-like polychlorinated biphenyls (DL-PCBs). Using contaminated soils from Sweden [64], they showed the occurrence of PCDDs and PCDFs in E. fetida tissues resulting from exposure, both in situ and in laboratory conditions.…”
