EC number: 260-828-5
CAS number: 57583-34-3
The 21-day LC50 for parental survival was 0.305 mg/L, the overall LOEC
was >0.134 mg/L and the overall NOEC was 0.134 based on measured
concentrations (Daphnia magna).
The key fish and algae studies of MMT(EHTG) were performed using
measured concentrations. A 100 % Water-Accommodated Fraction (WAF) (6.0
mg/L) was not lethal to zebra fish (B. rerio) (LC50 > 6 mg/L); however,
non-lethal effects with respect to the condition of the test animals
were reported; the NOEC was 3.6 mg/L (56 % of the WAF). A 99 % Water
Soluble Fraction (WSF) (1.84 mg/L) produced only a slight inhibitory
effect on S. subspicatus and the NOEC was 0.595 mg/L (33 % of the WSF).
Parental mortality was 100 % in Daphnia magna exposed to 50 % (0.694
mg/L) and 100% (2.315 mg/L) of the Water-Accommodated Fraction of
MMT(EHTG). Reproduction was not affected at concentrations up to 0.134
mg/L (10 % of the WAF). The 21-day LC50 for parental survival was 0.305
mg/L, the overall LOEC was >0.134 mg/L and the overall NOEC was
0.134 based on measured concentrations.
Toxicity to Microorganisms
The highest percent inhibition value obtained in the study for the test
substance vessels was 11.0 %. The EC50 value is therefore greater than
1000 mg/L, the highest concentration tested.
