Currently viewing:

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
Type of information:
experimental study
Study period:
1987
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: These data are regarded as reliable. Fugacity data suggests low losses would be expected by evaporation, however as no measurements made, only rated reliable with restrictions.
