Additional information

Generally, the substance is not supposed to be directly applied to soil and further is readily biodegradable. Hence, in case of indirect exposure to soil, the substance is expected to rapidly degrade. Therefore soil is not expected to be a compartment of concern and the risk to terrestrial organisms is regarded to be negligible.

Nevertheless, a long-term toxicity test with soil macroorganisms (earthworms, OECD 222) is available. No Observed Effect Concentration (NOEC) for mortality and weight changes was determined to be the concentration of 1000 mg test item/kg soil. The No Observed Effect Concentration (NOEC) for reproduction was determined to be the concentration of 316 mg test item/kg soil. Based on the results of these studies, it can be concluded that Sulfonic acids, C14-16 (even numbered)-alkane hydroxy and C14-16 (even numbered)-alkene, sodium salts has a low impact on terrestrial organisms.

Additionally, the bioaccumulation potential is low and the test substance is considered to cause low hazard to predators. Thus, a study with birds is not needed due to animal welfare reasons.
