“…Linear compartment models are used to analyze such data (e.g., for soil organisms; Janssen et al, 1991, and references therein). These models conceptualize an organism as a conglomerate of compartments, which represent mathematically distinct ''parts'' of the organ-ism with a recognizable accumulation/depuration behavior.…”

“…After introduction of the value of the elimination rate constant in the model equations for the exposure phase, the uptake rate constant can be estimated separately. Simultaneous estimation of rate constants from consecutive exposure and elimination studies has been used only by a limited number of authors for the one-compartment model (34). For two-compartment model studies (30,(35)(36) such an approach has not yet been used.…”

A novel method based on a first-order two-compartment model was used to determine the bioconcentration and toxicokinetic rate constants of six different polycyclic aromatic hydrocarbons (PAHs) in the freshwater isopod Asellus aquaticus, a common species in most European freshwater systems. Numerical integration and iterative parameter estimation techniques were applied to account for time-varying aqueous exposure concentrations. All PAHs exhibited a rapid uptake. Monophasic elimination patterns were observed for benzo[e]pyrene and benzo[a]pyrene (biological half-life t 0.5 : 7-8 days). For the other PAHs (anthracene, phenanthrene, pyrene, benzo[ghi]perylene) typical biphasic patterns were encountered with rapidly (t 0.5 : 0.6-2 days) and slowly (t 0.5 : 99to>1000 days) exchanging compartments. Some PAHs (pyrene and benzo[ghi]perylene) will hardly be eliminated during the normal life span of the organism. Bioconcentration factors (log BCF, wet weight; derived from rate constants) increased with molecular weight and K ow (n-octanol/water partition coefficient) from 2.6 L kg -1 (anthracene) to 5.7 L kg -1 (benzo-[ghi]perylene). A linear relationship was observed between log BCF and log K ow. It is argued that biotransformation of PAHs in freshwater isopods seems to play a minor role and that this species may be suitable for the assessment of the bioavailability of PAHs in littoral freshwater environments.

“…Studies on other animals suggest that Cd in the body tissue pool of prey is generally highly bioavailable to predators (Hispard et al, 2008;Ng and Wood, 2008;Xie et al, 2010). Janssen et al (1991) also showed that the Cd assimilation efficiency of other soil arthropod predators was higher than that in consumers. However, only a few studies have been reported in which pollutants influenced population variation (e.g.…”

a b s t r a c tEffects of cadmium (Cd) on collembolans and predatory mites have been well studied but Cd accumulation and biological transfer and the relationship between Cd trophic transfer and nitrogen (N) isotope fractionation and transfer in soil micro-arthropod food chains remain poorly understood. Here, we investigated the biological transfer and trophic toxicity of Cd and the effects of dietary Cd exposure on 15 N fractionation in animal tissues and N transfer from food in a soil collembolan (Folsomia candida)-predatory mite (Hypoaspis aculeifer) food chain using experiments conducted in plate and soil systems. Synchronized F. candida were fed yeast or wheat spiked with 0 (Control), 50 (Cd50), 100 (Cd100) or 200 (Cd200) mg Cd g À1 food for two weeks and were then offered to synchronized H. aculeifer as prey for two weeks. Cadmium concentrations in tissues of both the collembolan and its predator increased as the Cd concentrations in the food yeast or wheat increased in both the plate and soil systems, and the Cd concentrations in the food and the animals were all significantly and positively correlated. Except for the controls, the Cd bioaccumulation factor (BAF) between adults of predatory mites and consumer collembolans (0.20e1.13) was 2.5e14 times higher than that from food yeast/wheat to consumer collembolans (0.02e0.08). Cadmium transfer has not altered the reproduction of the filial generation collembolans but the reproduction of the predatory mite declined by 34.3% with the Cd concentration in its juveniles reaching 5.94 mg g N isotope application may be limited in Cd polluted soil ecosystems, and the N transfer function of soil food webs may be more vulnerable in polluted ecosystems.
