Ecotoxicological information

Short-term toxicity to aquatic invertebrates

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water, hence indicating that aquatic toxicity is unlikely to occur
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information
Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Reason / purpose for cross-reference:
reference to same study
Reason / purpose for cross-reference:
reference to same study
Reason / purpose for cross-reference:
reference to same study
Qualifier:
no guideline followed
Principles of method if other than guideline:
Saturated solutions of TMPTS in water were prepared; then the TMPTS in the solutions was quantitatively analyzed with UPLC.
GLP compliance:
no
Type of method:
other: UPLC was used for measuring water solubility
Water solubility:
3.6 µg/L
Conc. based on:
test mat.
Remarks on result:
other: no further information available, but standard conditions / room temperature assumed
Conclusions:
water solubility = 3.6 µg/L (insoluble; <0.1 mg/L)
The study (no GLP) was performed in accordance with national standard methods with acceptable restrictions on the substance to be registered itself, the test procedure is well documented and therefore reliability of Klimisch 2 has been assigned.
Executive summary:

The liquid chromatography was used for measuring water solubility in a non GLP study. Using the UPLC method, The water solubility of the test item was determined to be 3.6 µg/L at room temperature.
