“…Most metabolic, physiological, and behavioral processes in insects (e.g., oxygen consumption, locomotion) show an approximately exponential dependency on temperature within the range tolerated by the animal (Hoffmann 1985). Likewise, metal concentrations in invertebrates are reported to increase with increasing temperature (Douben 1989;Janssen and Bergema 1991;Van Hattum et al 1993;Bervoets et al 1996), although the reasons for such trends are usually unknown. Possible explanations for such temperature-controlled increases in metal content include declines in animal weight or metal efflux rate or increases in metal ingestion rate and assimilation efficiency.…”

“…The similarity of the Cd loss rates among the three Chaoborus species suggests that their Cd is likely bound at the cellular level in a similar manner (Croteau et al in press). Cadmium loss rates for aquatic isopods (Van Hattum et al 1993) and soil mites (Janssen and Bergema 1991) are also reported to remain constant over a range of temperatures. In contrast, Cd loss rates have been observed to increase with increasing temperature in some fish (Douben 1989) and terrestrial collembolans (Janssen and Bergema 1991).…”

“…The concentrations of nonessential trace metals such as cadmium are also reported to rise in organisms with increasing ambient temperature (Douben 1989;Janssen and Bergema 1991;Van Hattum et al 1993;Bervoets et al 1996), in part because these metals likely enter animals at uptake sites for essential metals such as calcium (Craig et al 1998). Exceptionally, the opposite (e.g., Pb accumulation by Asellus; Van Hattum et al 1993) or no effect of temperature (e.g., Cd uptake by Mytilus edulis, Jackim et al 1977) has occasionally been reported. Reports of temperature influencing metal bioaccumulation are generally not followed up with an identification of the biological processes responsible for the effect.…”

We exposed larvae of several species of the phantom midge Chaoborus to the trace metal cadmium (Cd) to determine whether Cd accumulation rates varied with ambient temperature. Because this predator is known to accumulate its Cd mainly from food rather than from water, we presented the Cd in food, that is, Cd-rich copepods taken from a lake near a metal smelter. Rates of Cd accumulation by larvae of Chaoborus americanus, C. flavicans, and C. punctipennis were measured at three temperatures (5, 14, and 22ЊC) covering the seasonal range encountered by these animals. The rates at which all species accumulated Cd increased with temperature. To explain these results, we fit our experimental data to a bioaccumulation model that allowed us to estimate Cd assimilation efficiency, Cd-efflux rate, and larval growth rate. Temperature-related changes in Cd accumulation rates were best explained by changes in the rate at which Chaoborus larvae ingested prey as well as the efficiency with which they assimilated Cd from their food. Neither the rate of larval growth nor the rate at which larvae lost Cd was influenced by temperature. Extrapolations of our laboratory results to the field suggest that our model results provide a realistic representation of the processes involved in Cd accumulation by larvae of this common aquatic insect.

“…A third possible exposure route is via the sediment (Mac et al, 1990;Cope et al, 1994;Allen-Gil et al, 1997). It is often stated that sediments constitute the most important reservoir or sink of metals and other pollutants in the aquatic environment (e.g., Salomons and FoK rstner, 1984;Luoma, 1989;Lee, 1992;Van Hattum et al, 1993). Indirect exposure to contaminated sediments will take place when "sh feed on benthic invertebrates such as chironomids and tubi"cid worms that are ingesting particulate matter.…”

“…In earlier studies, we investigated the toxicokinetics of several trace metals and the potential suitability of freshwater isopods for the monitoring of trace metal bioavailability (19)(20)(21). We further observed the capacity of freshwater isopods to accumulate PAHs and organophosphorus compounds (22,23).…”

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.
