“…Environmental Protection Agency, Organization for Economic Cooperation and Development, and Ministry of Agriculture of the People's Republic of China have already used the earthworm (Eisenia fetida) as an indicator organism to assess the potential biological effect of the chemicals if released into the environment. Equilibrium partitioning theory model has been developed to assess the bioaccumulative potential of commercial chemicals (Connell and Markwell, 1990;Armitage and Gobas, 2007). Enantioselective toxicity and bioaccumulation of pesticides in earthworms have got wide attentions in recent years.…”

“…We addressed this issue by using a static aqueous exposure test system with periodic (every 2-3 days) renewal of the test solution, which ensured consistent chemical exposure conditions during each study. Additionally, the potential importance of biota lipid content in determining BCF values has been noted in previous studies via various log K OW -log BCF correlations (Lord et al, 1980;Connell and Markwell 1990;Belfroid et al, 1993). Reviewing the bioconcentration measurements for organic compounds persistent in the environment, Connell commented that the coefficient for log K OW , which was considered as equivalent to log K LipidW , should be the lipid content of the organism rather than a conveniently fitted parameter (Connell 1988;Connell and Markwell, 1990).…”

Separate toxicity studies were conducted prior to bioconcentration studies using a range of chemical concentrations to establish the sublethal exposure conditions for the earthworms. The objectives of the present studies were to: (1) develop an experimental test system for estimating bioconcentration potentials of new and emerging munition compounds that partition into earthworms, using aqueous exposure media; and (2) apply this experimental model to establish original bioconcentration data for 4-NAN, 3,5-DNoTAME, and 2-M-5-NPYNE.

“…It is specific to the receptor, the route of entry, the time of exposure, and the matrix containing the contaminant (Anderson et al, 1999 contaminants, it is crucial to study the uptake kinetics of these chemicals in organisms. To describe the uptake kinetics of organic compounds in soils or sediments, the equilibrium partitioning theory, initially proposed by Shea (1989) and further developed by DiToro et al (1991), has frequently been applied (Connell and Markwell, 1990). It presumes that the uptake kinetics of organic chemicals in soil-and sediment-dwelling organisms is usually described as a simple hydrophobic partitioning process between pore water and lipids of the organisms.…”

Bioavailability of phthalate congeners, dimethyl phthalate, diethyl phthalate, di-n-butyl phthalate (DBP), di-(2-ethylhexyl) phthalate (DEHP), and dioctyl phthalate, to earthworms (Eisenia fetida) were studied when earthworms were exposed to two artificially contaminated agricultural and forest soils. Only DBP and DEHP were detected in earthworms. The uptake kinetics of DBP and DEHP in earthworms was fast within the initial 10 days followed by a nearly steady state for the subsequent 20 days. An equilibrium partitioning model could be used to describe the uptake kinetics of DBP and DEHP by earthworm in two types of soils (r ¼ 0:70920:864). The average biota-to-soil accumulation factors (BSAFs) of DBP and DEHP at 5 mg kg À1 in soil were 0.2770.07 and 0.1770.03, respectively, in agricultural soil, while the BSAFs were 0.2170.06 and 0.0770.02, respectively, in forest soil. The concentrations of phthalates in earthworms increased with increasing concentrations of phthalates in soil. There was a significant correlation between log C soil and log C worm , with r ¼ 0:99920:993, demonstrating a single linear partitioning of phthalates between soil and earthworms. The bioavailability of DBP and DEHP was assessed by Soxhlet, methanol, and methanol-water (1:1) extraction methods. Our results indicated that the extractable amounts of freshly added DBP and DEHP in soils by these extraction methods were significantly correlated with those in earthworms. It was observed that the extractable DBP and DEHP by the methanol and methanol-water (1:1) extraction methods decreased with their increasing residence time in soil. In contrast, the amount extracted by the Soxhlet extraction method did not show a similar decline. Therefore, Soxhlet extraction was a poor indicator of the bioavailability of DBP and DEHP to earthworms in soil, which could lead to overestimation of the risk of soilassociated DBP and DEHP. The extractable DBP and DEHP by methanol and methanol-water (1:1) significantly decreased over 440 days. Compared with the methanol-water (1:1) extraction method, the methanol extraction method was preferred for its ability to predict the bioavailability of DBP and DEHP in aged soils. r
