Toxicity to fish

In a 96 hour acute toxicity study, zebrafish (Danio rerio) were exposed to C 17 Methacrylate at nominal (loading) concentrations of 0 (control), 100 mg/L under static-renewal conditions in accordance with the OECD 203 test guideline. The water pH, temperature and dissolved oxygen were within acceptable guideline specifications. The 96 hour NOEC was ≥100 mg/L based on the nominal (loading) concentration of the test substance.

Toxicity to aquatic invertebrates

In a 48-hour acute toxicity study, neonate Daphnia magna were exposed to C 17 Methacrylate at nominal concentrations of 0 (control), 100 mg/L under static-renewal conditions in accordance with the OECD 202 guideline. The water pH, temperature and dissolved oxygen were within acceptable guideline specifications. Immobilization (mortality) and sublethal effects were observed daily. The 48 hour NOEC values determined in this acute toxicity study were >100 mg/L based on the nominal concentration of the test substance.

Toxicity to aquatic algae and caynobacteria

In a 72-hour algal growth study, cultures of Pseudokirchneriella subcapitata were exposed to C 17 Methacrylate at nominal concentrations of 0 (control), 100 mg/L under static conditions for in accordance with the OECD 201 guideline. The water pH, temperature and lighting intensity were all maintained within acceptable guideline specifications. This test was conducted utilizing modified exposure media, closed test system, and reduced inoculation density. The following effect concentrations (mg/L) were obtained after 72-based on nominal (loaded) concentration NOEC >100 mg/L.

Toxicity to microorganisms

The toxicity to microorganisms was determined in a GLP short-term respiration test according to OECD guideline 209 using domestic activated sludge. After 180 min an EC20 of > 1000 mg/L was obtained
