“…13,14,17,[19][20][21] Exposing the earthworm to the natural soil treated with pesticide is the most realistic scenario. However, many environmental factors greatly influence the effects of a pesticide on earthworms; soil properties such as pH and organic matter content, 11,22) dissolved organic carbon in pore water, 23) adsorptiondesorption hysteresis with sequestration in the soil, 12,[24][25][26] and microbial degradation. 20,27,28) Detailed kinetic analysis that assumes compartments of pore water, soil particles and biota has been applied to understand the behavior of a chemical in such a complex system based on the equilibrium partitioning (EP) theory.…”

The toxic effects of pesticides on earthworms, one of the most important bioindicators in the terrestrial environment, are closely related to their body burden determined by uptake, metabolism and excretion processes. Not only the passive diffusion via the outer skin from a dissolved fraction of pesticide but also the ingestion of contaminated soil and food governs the uptake process, with each contribution controlled by either the hydrophobicity of the pesticide or the soil organic matter. Although the available information is limited, earthworms are likely to metabolize pesticides via hydrolysis and oxidation (Phase I) followed by conjugation (Phase II), and low bioaccumulation is observed as a result for most pesticides. The acute toxicity in the soil exposure can be partly explained by the dissolved fraction of pesticide in pore water, but the contribution of dietary uptake and metabolism should be further studied to correctly evaluate pesticide toxicity.

“…References [75][76][77][78] found that the worm vermicasts sorbed higher amount of herbicides from the contaminated soil than the control soil due to the higher levels of organic carbon & more finer size of fractions in worm worked contaminated soils. Reference [79] found that due to earthworm burrowing actions, a greater degree of bound pesticides residues in soil was released as compared to those without worms.…”

“…Some are more recent but focus on compounds that are no longer permitted in Europe. This is the case with many studies on carbofuran (Anton et al 1993;Ruppel and Laughlin 1977), benomyl (Stringer and Wright 1976;Wright 1977;Wright and Stringer 1973), carbaryl (Neuhauser and Callahan 1990;Tu et al 2011), dieldrin and dichlorodiphenyltrichloroethane (Davis 1971). In Lee (1985), which is one of the major text books on earthworm biology and ecology, a review of pesticide effects on earthworms was presented.…”

Earthworms provide key soil functions that favour many positive ecosystem services. These services are important for agroecosystem sustainability but can be degraded by intensive cultural practices such as use of pesticides. Many literature reports have investigated the effect of pesticides on earthworms. Here, we review those reports to assess the relevance of the indicators of earthworm response to pesticides, to assess their sensitivity to pesticides, and to highlight the remaining knowledge gaps. We focus on European earthworm species and products authorised in Europe, excluding natural compounds and metals. We consider different organisation levels: the infra-individual level (gene expression and physiology), the individual and population levels (life-history traits, population density and behaviour) and the community level: community biomass and density. Our analysis shows that earthworms are impacted by pesticides at all organisation levels. For example, pesticides disrupt enzymatic activities, increase individual mortality, decrease fecundity and growth, change individual behaviour such as feeding rate and decrease the overall community biomass and density.Insecticides and fungicides are the most toxic pesticides impacting survival and reproduction, respectively.
