Abstract
Acute and chronic ecotoxicity tests with lindane were carried out
using the soil invertebrates Eisenia fetida, Enchytraeus albidus,
and Folsomia candida. To assess the influence of soil type on the
bioavailability, these tests were carried out in a standard artificial OECD soil
and in sandy and loamy field soil. For each species, differences in lindane
toxicity were observed for the three soil types. These differences were,
however, not related to the organic matter content. The relative differences in lindane
toxicity between the soils was species-specific. These results therefore
indicate that the pore-water hypothesis, i.e., the pore-water contaminant
fraction being the toxicological bioavailable fraction, is not always applicable
for organic substances. NOEC, NEC, as well as EC10 data were
subsequently used to calculate hazardous concentrations for 5% of the species;
this methodology, aimed at setting environmental quality criteria, is discussed.
