“…Data for sterols and oil hydrocarbons in the Kaohsiung Harbour sediments are presented in Table 1. Concentrations of total coprostanol show a wide range 0.58-128 lxg g-] dry wt (mean 20.8 Ixg g-l) which is comparable to that found in sediments from the canals and lagoon of Venice, Italy (Van Vleet et al, 1988). Their coprostanol concentrations ranged from 0.2 to 40.9 ~tg g-l; the highest concentration was found in the interior canals.…”

Abstract-Chemical analyses and bioassays were used in conjunction to assess the quality of sediments of the Venice lagoon. Organic micropollutants (polycyclic aromatic hydrocarbons [PAHs] polychlorinated biphenyls [PCBs], and chlorinated pesticides) were extracted from sediment samples and analyzed by gas chromatography after fractionation into classes of compounds. The Vibrio fischeri test was used to assess the acute toxicity of sediment extracts. The test was applied to organic extracts before cleanup and to extracts purified from sulfur and fractionated into single classes of compounds. Extracts before purification were much more toxic than single fractions. In particular, sulfur was toxic to V. fischeri. For PAHs and PCBs the 50% effective concentration (EC50) and EC20 values were determined using natural and spiked extracts (EC50 ϭ 0.5 g/ml and 1.4 g/ml, respectively; EC20 ϭ 0.13 g/ml and 0.17 g/ml). Sensitivity limits of the method for these compounds were also estimated as was an EC50 value of elemental sulfur dissolved in ethanol (0.022 g/ml). A mathematical model was used to fit the concentration-response data to a sigmoid curve.
