Applicant's summary and conclusion
- Conclusions:
- Using the US EPA EPI-Suite (v.3.12) Level III fugacity model (US EPA, 2000), the environmental distribution of the C18 to C24 components of the registered substance have been calculated and the percent distributions in air, water, soil and sediment are summarized in the table below.
Media Percent Distribution
Air 0.28 to 0.38
Water 3.74 to 3.8
Soil 27.6 to 28
Sediment 68.0 to 68.4
From these results, the components of the reaction products of 1-decene, 1-dodecene, and 1-octene, hydrogenated are expected to partition to sediment and soil as well as to wastewater solids. In sediment and in soil, the registered substance is expected to exhibit a short half-life based on its readily biodegradability characteristics (>60% in 28 days) in standard OECD ready biodegradation tests in freshwater. As pointed out previously, materials that are readily biodegradable in freshwater are expected to rapidly biodegrade in other environmental compartments including sediment and soil (ECHA 2008).
Registrant's Comments: The US EPA EPI-Suite modeling program has been extensively used in the OECD SIDS and the US EPA High Production Volume (HPV) programs and more importantly, the US EPI-Suite program is an integrated predictive tool in the OECD Toolbox to calculate physico-chemical and environmental fate properties for chemicals. Hence, the need to supply QMRF and QPRF for commonly applied EPI-Suite models is not warranted given its already accepted use in global regulatory notifications and its integration and underpinning in the OECD Toolbox for REACH - Executive summary:
Environmental distribution as calculated by the Level III fugacity model (US EPA, 2000a) indicates that the C18-C24 components in the registered substance (i.e., reaction products of 1-decene, 1-dodecene, and 1-octene, hydrogenated) will partition mainly to sediment (68.0 - 68.4%) and soil (27.6-28%) compartment with very little into the water (3.74-3.8%) and air (~0.3- 0.4%) compartments. Hence, the registered substance is expected to partition mainly into sediment and soil as well as to wastewater solids, with very little into water and the least into air. .
