“…This also holds for midges from the exposed Borkel (Pd) population, although short-term experiments did not detect any cadmium tolerance in these midges (Postma et al in press), indicating differences in sensitivity between short-and long-term experiments. The present observations accord with Wentsel et al (1978), who illustrated that chironomids directly obtained from metal-exposed sites were less affected by metal exposure than conspecifics from a clean location. However, increased tolerence to cadmium, as found in the present study, did not suppress effects on larval mortality, although all tested concentrations were below the average cadmium concentration found at the studied field sites (270 nM Cd).…”

Cadmium tolerance in field populations of the midge Chironomus riparius was studied by comparing the effects of chronic cadmium exposure on several life-history parameters using first generation, laboratory-reared animals. Differences between populations of C. riparius were therefore assumed to have a genetic basis. Field populations naturally exposed to metals were less sensitive to cadmium compared to unexposed populations, when larval development time and hatchability of the egg masses were measured. However, larval mortality still increased with cadmium exposure and no differences between exposed and unexposed populations were observed. Furthermore, life-history patterns differed between metal tolerant and nontolerant populations grown under control conditions. Metal tolerant populatipns were characterized by a high control mortality (50%) or an increased larval development time (with 30%). The results, therefore, indicated the presence of costs of tolerance, while a direct selection on certain life-history characteristics due to metal pollution was absent. E n v i r o n m e n t a l C o n t a m i n a t i o n a n d T o x i c o l o g yAn increase in metal tolerance of exposed populations is well documented for bacteria (Trevors et al. 1985), plants (Antonovics et al. 1971;Macnair 1993), and several animal species (Klerks and Weis 1987;Posthuma and Van Straalen 1993). Among Diptera, metal tolerant populations are well known for the fruit fly Drosophila melanogaster (Chapco et al. 1978;Magnusson and Ramel 1986;Nassar 1979), but to a less extent for chironomids. ...

“…Yet, observations on increased metal tolerance in chironomids have shown contradictory trends. Wentsel et al (1978) demonstrated that larvae of Chironomus tentans from a metalpolluted site were less affected by exposure to metalpolluted sediment than their conspecifics from a clean location (based on differences in survival, growth and avoidance response) . Furthermore, selection experiments in the laboratory showed that Chironomus riparius can increase its tolerance to cadmium within a few generations (Postma & Davids, 1995) .…”

Key words : Chironomus riparius, metal tolerance, Cd, Zn, Fe Abstract Metal tolerance in Chironomus riparius (Diptera) populations from contaminated streams was studied by comparing the effects of cadmium, zinc and iron on first generation laboratory reared midges . First instar larvae were exposed for four days, after which surviving larvae were counted and their length measured . Larvae from two highly polluted sites, kept under control conditions, grew substantially slower than those from other populations . All populations showed the same growth responses to increased zinc concentrations, but differences were found in the responses to both cadmium and iron . Since population differentiation was demonstrated in first generation laboratory animals, it is suggested that the differences between populations of C . riparius have a genetic basis .

“…Bryan, 1979 ;Luoma & Carter, 1991) . The isopod Asellus meridianus, the midge Chironomus tentans, and the polychaete Nereis diversicolor, for example, are more resistant to metals at contaminated sites than at sites free of such toxicants (Brown, 1976 ;Wentsel et al ., 1978a ;Bryan, 1979) . Lastly, the cosmopolitans among the test species should be favoured in the tests, given the choice, because of their higher overall ecological relevance and better comparability between sites .…”

“…(1977b) found oligochaetes to be highly tolerant of metals . Assessment of the sensitivity of oligochaetes to toxicants is further complicated by the fact that these organisms can develop site specific resistances (Wentsel et al ., 1978a) . A simple statement about the sensitivity of oligochaetes (or any other organism group) to contaminants is unlikely to be valid, for differences between species, as well as between their responses to different toxicants can be significant (Chapman et al ., 1980(Chapman et al ., , 1982Chapman & Brinkhurst, 1984 ;Wiederholm et al ., 1987) .…”

Benthic metazoans play a key role as test organisms in toxicity analyses of aquatic ecosystems . This report gives an overview of the species of benthic metazoans used for the assessment of toxicity in freshwater and marine sediments, as well as of the criteria relevant to the choice between test species and procedures . The main applications of these organisms are mono-species bioassays, test-batteries, analyses of benthic communities and bioaccumulation studies . Sediment toxicity assays, including acute and chronic exposures, have been developed for nematodes, insects, oligochaetes, polychaetes, crustaceans, molluscs and echinoderms . At least 30 species of freshwater and 71 species of marine and estuarine benthic metazoans have thus far been used in sediment toxicity bioassays . Although aquatic pollution is a world-wide problem, most sediment toxicity bioassays have been developed for organisms native to Europe and North America . The most common bioassay endpoints are mortality, development, growth and behavioural responses . The value of genetic, biochemical, physiological and pathological responses as toxicity endpoints is currently being investigated . The quest for additional test species and protocols is still a worthwhile endeavour in sediment ecotoxicology . Abstract 215Introduction 215
