Description
Summary:[Display omitted] •Meta-analyses were performed on metallic element accumulation in earthworms.•Metallic element accumulation was significant in earthworms when treated together.•The intensity of body concentration enrichment had a highly species-specific pattern.•Copper uptake in earthworms increased significantly with the increase in soil pH.•Lead accumulation intensity decreased significantly with time in the studied species. The responses of earthworms to excess soil element concentrations are well studied. However, published information on the metallic element accumulation in individuals is controversial. In this paper, the published data on earthworm As, Cd, Cr, Cu, Ni, Pb, and Zn whole body concentrations were evaluated in individuals collected from contaminated and uncontaminated (control) soils, using meta-analyses. The role of soil pH and exposure time as potential influencing factors on metal accumulation was also assessed. Based on the evaluations, the accumulation of each metallic element was significantly (p
