“…in the contaminated canal sediment. The calculated total concentrations of elemental sulphur at the EC 50 concentrations of sediment in the Microtox test suspensions were higher, by a factor 13 in the Teltow canal sediment and by 34 in the reference sediment, than the concentration required to elicit the toxicity of pure elemental sulphur (EC 50 =15.2 g/L; Svenson et al 1998). Assuming that elemental sulphur was the single toxic substance in the bacterial luminescence assays (cf.…”

“…The corresponding fraction of bioavailable elemental sulphur in the methanol extract of the reference sediment was 7.3%. The previously observed decrease in acute toxicity with time with a half-life of less than one hour (Svenson et al 1998) probably depends on interconversion of elemental sulphur in this fraction. The significance of this and the subsequent decrease in the acute toxicity were further supported by the results of toxicity assays using longer exposure times (Table 1).…”

“…Moreover, this sulphur species was identified as the dominant toxicant that could alone account for the whole Microtox toxicity (Svenson et al 1998). The aim of this study was (1) to examine the relation between the acute aquatic toxicity measured in short-term toxicity assays and operationally defined sediment fractions of elemental sulphur and (2) to provide evidence for the conversion of the initially toxic form into non-toxic species.…”

The proportions of elemental sulphur species in sediment from a contaminated area and a reference sediment sample were compared with the acute toxicity measured in short-term toxicity tests. Octameric elemental sulphur was separated into three operationally defined fractions. Here we show that octameric elemental sulphur contributes to the acute toxicity measured by bioluminescence inhibition. Our findings show that only a small part of extractable elemental sulphur was effective during exposure to the test organisms. A firmly bound fraction of sulphur was found in a contaminated sediment. This information has to be taken into account while interpreting the acute sediment toxicity.

“…Free oleic acid and other free fatty acids can originate from many industrial processes including paper manufacture as was described by Morales et al(1992). The cyclic form of elemental sulfur, S8 0 , is found in the aquatic environment (sediment, pore water) and its toxicity to V. fischeri in organic sediment extract was discussed earlier by Svenson et al(1998).…”

“…3) was less than the sum of their individual effects (Table 2). A, OA and S8 0 are hydrophobic substances, whichh have the potential to bioaccumulate and cause the toxic effect on biological membranes (Svenson, 1998;Pardos, 1999;Cetkauskaite et al, 2004). Due to their hydrophobic properties all these substances are found in polluted sediments.…”

The objective of this research was to evaluate the toxicity of the industial xenobiotic Aroclor 1248 (A) and natural origin substances~elemental sulfur (S80) and oleic acid (OA) and their binary mixtures to V. fischeri bioluminescence during the prolonged exposure time (up to 60 min). The bioluminescence quenching test was used to determine the toxic effects. Full factorial experiment design and multiple regression analysis and the comparison of binary mixture effect with the sum of effects of individual chemicals were used for the evaluation of combined effects of toxicants.The analysis of general trend of mixture toxicity to bioluminescence showed that mixture toxic effects were reversible up to 60 min. Data analysis revealed different joint effects, which were depended on mixture composition. S80 enhanced toxic effect of A and acted additively with synergistic interaction. Hydrophobic OA in mixture with A acted antagonistically and in mixture with sulfur caused an additive effect with antagonistic component of interaction.It was concluded that low concentrations of natural toxic substances present in environmental samples as mixtures of chemicals can define the toxicodynamic character of industrial xenobiotics.
