Description of key information
Based on the Level III Fugacity Model the half life period of 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate was estimated. As per the values it was observed that in general 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate persistence time is 414 hrs.The half life period of 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate in water is 360 hrs therefore it is considered that a substance will qualify as not persistent as the period does not exceed the EPA criteria . So, it can be confirmed that the substance is readily biodegradable in water medium. Whereas the half life period of 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate in sediment is 3360 hrs respectively and based on these values it is indicated that the chemical is persistent in sediment medium i.e not readily biodegradable.
