Conclusions:

The LC0 value for test material for short term toxicity to fish was determined to be 1000 mg/l for 96 hrs.

Executive summary:

Acute toxicity range finding test was conducted with bluegill (Leponis Macrochirus) sunfish with test material. Ten fish per concentration were tested in 25-L pickle jars using 20L of water. Test concentrations were 0, 0.1, 1.0, 10, 100 and 1000 mg/l for sodium p-sulfophenyl methallyl ether. The test chemical was introduced as aqueous solutions without solvents prior to introducing the fish. Mortality, behavior, dissolved oxygen, pH and temperature were recorded daily for 96h.After the experiment, the LC0 value for test material for short term toxicity to fish was determined to be 1000 mg/l for 96 hrs. Based on the value, the test material was considered to be non-toxic to aquatic organism and can be considered to be not classified as per the CLP regulation.

Additional information

Short term toxicity to fish:

Short term toxicity of test material on fish was described in a peer reviewed journal for two differenty fish as follows:

For the fish bluegill (Leponis Macrochirus) , acute toxicity range finding test was conducted with bluegill (Leponis Macrochirus) sunfish with test material. Ten fish per concentration were tested in 25-L pickle jars using 20L of water. Test concentrations were 0, 0.1, 1.0, 10, 100 and 1000 mg/l for sodium p-sulfophenyl methallyl ether. The test chemical was introduced as aqueous solutions without solvents prior to introducing the fish. Mortality, behavior, dissolved oxygen, pH and temperature were recorded daily for 96h.After the experiment, the LC0 value for test material for short term toxicity to fish was determined to be 1000 mg/l for 96 hrs. Based on the value, the test material was considered to be non-toxic to aquatic organism and can be considered to be not classified as per the CLP regulation.

For , another fish rainbow trout acute toxicity range finding test was conducted with rainbow trout with test material. Ten fish per concentration were tested in 25-L pickle jars using 20L of water. Test concentrations were 0, 0.1, 1.0, 10, 100 and 1000 mg/l for test material. The test chemical was introduced as aqueous solutions without solvents prior to introducing the fish. Mortality, behavior, dissolved oxygen, pH and temperature were recorded daily for 96h.After the experiment, the LC0 value for test material for short term toxicity to fish was determined to be 1000 mg/l for 96 hrs.

Based on these values, the test material was considered to be non-toxic to aquatic organism and can be considered to be not classified as per the CLP regulation.
