Toxicity to aquatic algae and cyanobacteria

Administrative data

Endpoint:

toxicity to aquatic algae and cyanobacteria

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

other:

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.
