Reference 2

Endpoint:

short-term toxicity to aquatic invertebrates

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2013

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods

Justification for type of information:

read accross to the similar Zn salt, because Zn is the more toxic stannate; worst case scenerio. Stannate goup is identical

Qualifier:

equivalent or similar to guideline
