Pontoscolex corethrurus bioaccumulates chlordecone far more than epigeic earthworms, averaging 18× (Nitisol) and 13× (Andosol) soil concentrations.
- Why it matters: Chlordecone persists long after being banned, yet its contamination impacts on earthworms—key for soil functioning—remain poorly quantified across soil types and exposure gradients.
- What they did: Earthworms and soils were sampled from 24 banana fields spanning 0 to 2280 μg kg−1 chlordecone, measuring whole-body CLD and transformation products (A1, A2, chlordecol) along Nitisol and Andosol gradients.
- The result: Bioaccumulation in P. corethrurus was 8× higher than in epigeic earthworms, CLD bioaccumulation factor increased with soil concentration, and A1/A2 were detected in earthworms (10% and 47%) despite not being quantified in soils.
