Description of key information

Estimation Programs Interface (EPI Suite, 2017) prediction model was run to predict the half-life in water and sediment for the test compound (2E)-3,7-dimethylocta-2,6-dien-1-yl 2-phenylacetate (CAS No. 102 -22 -7). If released in to the environment, 10.5 % of the chemical will partition into water according to the Mackay fugacity model level III and the half-life period of test chemical in water is estimated to be 37.5 days (900 hrs). The half-life (37.5 days estimated by EPI suite) indicates that the chemical is not persistent in water and the exposure risk to aquatic animals is low whereas the half-life period of test chemical (2E)-3,7-dimethylocta-2,6-dien-1-yl 2-phenylacetate in sediment is estimated to be 337.5 days (3240 hrs). Based on this half-life value, it indicates that test chemical (2E)-3,7-dimethylocta-2,6-dien-1-yl 2-phenylacetate is persistent in sediment.
