“…The fat content of earthworm is 3–8%, thus lipid removal is critical for earthworm preparation. Freeze out, liquid–liquid partition, and GPC are generally used for lipid removal of high fat content samples including earthworm . However, all these procedures are tedious and time consuming.…”

“…Earthworms, a major part of the soil fauna biomass, process large amount of soil through their feeding and burrowing activities, consequently, they can accumulate many organic and inorganic pollutants . Earthworms play a key role in terrestrial ecology because they form a large part of the diet of terrestrial vertebrates, and serve as an important link in the transport of PCBs and other hydrophobic organic contaminants from the soil to organisms high up in the terrestrial food chain .…”

Soil and earthworms are important objects in soil pollution assessment and environmental behavior and toxicity study for polychlorinated biphenyls. Accelerated solvent extraction and solid-phase extraction are generally required for the extraction and clean-up of polychlorinated biphenyls in soil and earthworm, which are tedious and time-consuming. In this work, a modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) procedure combined with gas chromatography and triple quadrupole mass spectrometry was developed for the determination of 20 selected polychlorinated biphenyl congeners in soil and earthworm. Different extraction times, solvents, and clean-up adsorbents were compared and optimized. The average recoveries from spiked soils ranged between 70 and 120% with satisfactory relative standard deviations for all the polychlorinated biphenyls. In earthworm, the recoveries of polychlorinated biphenyls 180, 183, and 189 were relatively low (< 70% in some spiking levels) compared to that of the other polychlorinated biphenyls. The limits of quantification were in the range of 0.01-0.05 ng/g. The method was successfully applied to the analysis of 66 agricultural soils. To our knowledge, a combined method based on QuEChERS for the determination of polychlorinated biphenyls in soil and earthworms has not been published before. The procedure proved to be simple, sensitive, efficient, and environmentally friendly.

“…The enantiomers possessing the same physical and chemical properties show different activities in biological systems because of their different interaction with enzymes or other naturally occurring chiral molecules (Garrison, 2004). In that case, enantiomers display different bioavailability effects in organisms Diao et al, 2011;Xu et al, 2009Xu et al, , 2011Xu et al, , 2014.…”

h i g h l i g h t s• The bio-soil accumulation factors of bifenthrin was about 4 times greater than that of lambad-cyhalothrin.• Lambad-cyhalothrin was more easily to be adsorbed in soil than bifenthrin.• The bioaccumulation of lambad-cyhalothrin and bifenthrin in earthworm was enantioselective.• A negative relationship between Log BSAF S and Log K ow was observed. a r t i c l e i n f o a b s t r a c tIn this study, the bioavailability and enantioselectivity differences between bifenthrin (BF, typeⅠpyrethroid) and lambad-cyhalothrin (LCT, type Ⅱ pyrethroid) in earthworm (Eisenia fetida) were investigated. The bio-soil accumulation factors (BSAFs) of BF was about 4 times greater than that of LCT. LCT was degraded faster than BF in soil while eliminated lower in earthworm samples. Compound sorption plays an important role on bioavailability in earthworm, and the soil-adsorption coefficient (K oc ) of BF and LCT were 22 442 and 42 578, respectively. Metabolic capacity of earthworm to LCT was further studied as no significant difference in the accumulation of LCT between the high and low dose experiment was found. 3-phenoxybenzoic acid (PBCOOH), a metabolite of LCT produced by earthworm was detected in soil. The concentration of PBCOOH at high dose exposure was about 4.7 times greater than that of in low dose level at the fifth day. The bioaccumulation of BF and LCT were both enantioselective in earthworm. The enantiomer factors of BF and LCT in earthworm were approximately 0.12 and 0.65, respectively. The more toxic enantiomers ((+)-BF and (−)-LCT) had a preferential degradation in earthworm and leaded to less toxicity on earthworm for racemate exposure. In combination with other studies, a liner relationship between Log BSAF S and Log K ow was observed, and the Log BSAF S decreased with the increase of Log K ow .

“…Their biological activities can also influence the accumulation and/or biodegradation of inorganic contaminants including heavy metals (Lingxiangyu et al 2010). Many authors have shown that bioassays provide a general indication of metal toxicity in soils cycle (Das et al 2011;Yu et al 2012;Xu et al 2014;Findoráková et al 2017;Maity et al 2018). These tests can be successfully used to evaluate potential toxicity and to assess the environmental risks of heavy metals.…”

This study was conducted to investigate heavy metals bioaccumulation in industrialized soils in surrounding of Košice city (Slovakia), using earthworms. In the present research, we used ecotoxicity tests with Dendrobaena veneta (7 and 28-day bioassays) to infer about potential toxic risks to the agricultural (A) and permanent grass vegetation (PGV) of soils around the plant U. S. Steel Košice. The total Fe, Cu, Zn, Pb, Cd, Cr and As contents and eco-toxicological tests of industrialized soils from the Košice area were performed for 12 sampling sites in years 2016 – 2017. An influence of the sampling sites distance from the largest steel producer plant on the total concentrations of heavy metals was determined for Fe, Cd, Cr and As. It was found that earthworms (Dendrobaena veneta) in some cases caused a decrease of metals concentration in contaminated soils, the largest metal concentration differences were recorded in the samples PGV (4) U. S. Steel-plant-main gate. The results of the bioaccumulation factors of heavy metals in D. veneta (BAFs/7-28 d) are < 1 for the studied metals order in the sequence: Cr < Fe < Pb < Cu < As and > 1 for Zn > Cd.
