Description of key information

Additional information

Only one study (Hartenstein, 1982) was available, but it was not taken into account for the assessment because it was of reliability 3.

This study was not in accordance to the standardized method, because of the nature of the test medium (horse manure or activated sludge) and the concentrations were expressed in percentage of substance added to the sludge. The exact concentrations could not be known due to the variability of solids in the sludge and the microbial activities. No information was available about the test organisms, the exact test concentrations and the control group.
