[ref. ID; 6701]

Test system

Single-species and multi-species toxicity test

Microcosm

Three trophic levels: producers (mixotrophic phytoflagellate Cryptomonas sp. (strain SAG 26.80 from the Experimental Phycology and Culture Collection of Algae, Gottingen, Germany)) - consumers (predatory ciliate Urotricha furcata (by Th. Weisse (Austrian Academy of Sciences, Mondsee, Austria) and originally derived from the mesotrophic Lake Mondsee, Austria) - decomposer (unspecified bacterial community (originated from the non-axenic stock cultures of flagellates and ciliates)).

Toxicants

Parathion-methyl, Prometryn.

Test design

Static test system in 300 ml Erlenmeyer flasks filled with 100-150 mL cell suspension and closed with air-permeable lids. Modified WC medium (final nitrate concentration of 0.2 mM).

Measurements/observations

Cell number.
