“…The maximum AVS concentrations observed in L. Tantare sediments are typical for surficial shield lake sediments of southern Ontario and Quebec (e.g. Nriagu and Soon 1985;Huerta-Diaz et al 1993). They are also comparable to those observed in estuarine and coastal sediments (e.g.…”

The toxicity and accumulation of Cd from sediment by benthic invertebrates was measured along a Cd gradient created in nature. The efficacy of acid-volatile sulfide (AVS) concentrations in improving the prediction of biological effects in nature is also evaluated for the first time. The Cd concentration of sediments from a shield lake in Quebec was adjusted to obtain Cd : AVS ratios of from 0.05 to 10. The sediments were then subjected to in situ colonization by invertebrates over a 1 -yr period. Cd concentrations in pore waters were very low at Cd : AVS molar ratios < 1 but increased markedly at ratios > 1. The results of previously published laboratory bioassays suggest that Cd would not be toxic to invertebrates when the molar ratio of Cd : AVS was c 1. The biological effects of contaminated sediment varied greatly among taxa, as determined by both an animal's sensitivity to Cd and the animal's behavior. The abundance of only one of the insect taxa present, Chironomus (salinarius gp.) sp., was significantly related to the Cd : AVS molar ratio. For the other taxa present, there was no relationship between either abundances or growth rates and the Cd : AVS molar ratio. The general lack of expected toxicity at the high Cd : AVS molar ratios in our field study can be explained by the differing sensitivities to Cd for the animal species used in the laboratory and in the field and by the relatively low concentrations of Cd in excess of AVS even at the highest Cd: AVS molar ratio.Most of the anthropogenic trace metals present in aquatic environments are associated with the solid phase of bottom sediments. The availability of these trace metals to benthic organisms has been the subject of numerous studies. Useful relationships have been found in the field between metal accumulation by animals and both dissolved metal concentrations (Tessier et al. 1993) and oxic sediment metal concentrations normalized to hydrous

Sulfur isotopes in otoliths allow discrimination of anadromous and non-anadromous ecotypes of sockeye salmon (Oncorhynchus nerka)

Oncorhynchus nerka occur both as anadromous sockeye salmon that spend most of their life in the ocean, and as non-anadromous kokanee salmon that remain in fresh water their entire lives. We assessed whether stable isotopes of sulfur (δ 34 S) in otoliths could be used to distinguish sockeye salmon and kokanee ecotypes that are otherwise difficult to identify when they share a common freshwater rearing environment. We also investigated the chemical link between salmon and their diet by measuring δ 34 S in various fish tissues (eggs, muscle, scales) and zooplankton. δ 34 S (mean±SE) in sockeye salmon eggs (18.7±0.4‰) and marine zooplankton (20.5±0.1‰) were enriched by 10-14‰ compared with kokanee eggs and freshwater zooplankton. δ 34 S in the otolith cores of sockeye salmon (19.2±0.7‰) and kokanee salmon (5.3±1.1‰) were similar to δ 34 S in marine and freshwater zooplankton, respectively, indicating that the core is derived from maternal yolk tissue and reflects the maternal diet. δ 34 S in the freshwater growth zone of otoliths did not differ significantly between sockeye (5.9±1.1‰) and kokanee salmon (4.4± 1.2‰), and was similar to freshwater zooplankton. The mean difference between δ 34 S in the otolith core and first year of growth was 13.3±1.4‰ for sockeye and 0.65±1.3‰ for kokanee salmon. A quadratic discriminant function developed from measurements of δ 34 S in otoliths of known maternal origin provided perfect classification rates in cross-validation tests. Thus, sulfur isotope ratios in otoliths are effective in discriminating between anadromous and nonanadromous ecotypes of O. nerka.

“…However, their broadness suggests either poor crystallinity or small size as observed in natural samples. It is generally accepted (Volkov and Rozanov 1983) that elemental S is formed in sediments by the oxidation of iron sulfides and is often the preferred pathway when iron oxide or manganese oxide (Nriagu 1968) are present. Nriagu and Soon (1985) showed that the isotopic composition of elemental S in several lakes was the same as the AVS and deduced that AVS must have been the source.…”

Greigite and the magnetic properties of sediments

X‐ray diffraction spectra of freeze‐dried sediments from a lake in the English Lake District positively identified the presence of greigite, a magnetic iron sulfide (Fe3S4) mineral. The sediments also show considerable loss of magnetic intensity when wet samples are allowed to oxidize. Several hypotheses have been proposed elsewhere to explain the intensity loss, but an assessment of the evidence suggests that oxidation of greigite is responsible in these sediments. Data from several lakes and from laboratory experiments are used to deduce the environmental requirements for greigite formation. These conditions of high labile C concentrations, good sources of labile Fe and S, and an oscillating oxycline depth in the sediments are likely to be found only in mono‐ or dimictic eutrophic lakes, estuaries, and salt marshes and are unlikely to be found in meromictic lakes, unstratified lakes, oligotrophic lakes, or deep‐sea sediments.
