Summary
This meta-analysis synthesises empirical evidence on the role of earthworms in accelerating biogeochemical cycling of potentially toxic elements in soils. The review suggests that earthworm activity generally increases PTE cycling and mobility rates through bioturbation, casting production, and modification of soil chemical conditions, though context-specific effects likely vary by soil type, element speciation, and earthworm species. The findings have implications for soil remediation strategies and understanding contaminant fate in terrestrial ecosystems.
Regional applicability
The meta-analysis draws on global literature and applies to temperate soil systems including those in the United Kingdom. Findings on earthworm-mediated PTE mobility are relevant to UK soil remediation practice and understanding contaminant behaviour in British agricultural and contaminated land contexts, though species composition and soil characteristics may influence local applicability.
Key measures
Rates and extent of potentially toxic element cycling and mobility in soil; earthworm bioturbation and casting effects; soil chemical condition modifications
Outcomes reported
The meta-analysis synthesised empirical evidence on how earthworm activity affects the biogeochemical cycling and mobility of potentially toxic elements (PTEs) in soils across multiple studies.
