Abstract:
The International Standardization Organization recently launched a soil toxicity test with snails (Helix aspersa). We assessed the sensitivity of this test for seven polycyclic aromatic compounds. Control animals had 100% survival and low variability for growth measurements. Maximum exposure concentrations of 2,800 mg/kg (4,000 mg/kg for acridine) had no effect on survival. Similarly, growth (biomass and shell size) was not affected by pyrene, fluoranthene, fluorene, carbazole, phenanthrene, or acridine, whereas dibenzothiophene gave a 10% effect concentration of 1,600 mg/kg. Measured internal concentrations of carbazole, dibenzothiophene, and acridine increased with increasing soil concentrations, but biota-soil accumulation factors were low (0.002-0.1). Compared to previously tested organisms, with all being exposed in the same soil type and under similar test conditions, the H. aspersa test was relatively insensitive to all substances.
