Sampling and analysis

Analytical monitoring:

yes

Details on sampling:

Chemical analyses of water samples were conducted before and after each renewal.

Test organisms

Test organisms (species):

other: Lymnaea stagnalis

Details on test organisms:

Pond snails (Lymnaea stagnalis) were bred at 23 + 1 °C under a 12h photoperiod. The snails were fed daily with lettuce, commercial fish food and calcium tablets. 2-3 months-old organisms (814 ± 332 mg whole body weight) were used in the 96h lethality tests.

Any other information on results incl. tables

In all tests, the pH dropped about 1 unit and the oxygen to half of its saturation level after 24h exposure. This is probably due to the presence of feces from the snails.
