Short-term toxicity to fish

A short term toxicity to fish study does not need to be conducted if a long term toxicity to fish study is available

 

Long-term toxicity to fish

In an OECD 210 study, conducted according to GLP, exposure of newly fertilized eggs of the fathead minnow,Pimpephales promelas, to the test material under semi-static conditions was determined to have no effect on the survival or growth of the larvae. The No Observed Effect Loading Rate (NOELR) was 100 mg/L loading rate WAF.

Short-term toxicity to aquatic invertebrates

In an OECD 202 study, conducted according to GLP, the 48-Hour acute toxicity of the test material to the freshwater invertebrate daphnia magna is Effect Loading (EL)50 greater than 100 mg/L loading rate WAF. The No Observed Effect Loading rate is 100 mg/L loading rate WAF.

 

Long-term toxicity to aquatic invertebrates

In an OECD 211 study, conducted according to GLP, the long-term toxicity of the test material to the freshwater invertebrate,Daphnia magna,was investigated under semi-static conditions. The 21‑Day EL50 values for immobilization in the parental daphnia generation (P1) and reproduction, based on nominal loading rates, were estimated to be greater than 100 mg/L loading rate WAF. The No Observed Effect Loading rate (NOEL) was considered to be 100 mg/L on the basis that at this test concentration there were no significant mortalities (immobilization) observed in the parental generation (P1) and that there were no significant differences (p>0.05) between the control and the 100 mg/L loading rate WAF test group in the numbers of live young produced per adult by Day 21.

 

Toxicity to aquatic algae

In an OECD 201 study, conducted according to GLP, the acute toxicity of the test material to aquatic algae (Pseudokirchneriella subcapitata) is Effect Loading (EL)50 greater than 100 mg/L loading rate WAF, and the No Observed Effect Loading Rate is 100 mg/L loading rate WAF.

 

Toxicity to microorganisms

In an OECD 209 study, conducted according to GLP, the 3 hour toxicity of the test material to activated sewage sludge micro-organisms is EC50 greater than 1,000 mg/L. The 3 hour NOEC is 1,000 mg/L.
