Based on the Level III Fugacity Model the half life period of the substance 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 prsistence time is 414 hr.The half life period of 3a,4,5,6,7,7a-hexahydro-4,7- methanoinden-6-yl acetate in air is 0.046 hrs and water is 360 hrs and so the substance is not persistent in air and water medium . In soil the persistence level is 720 hrs and so the substance is not persistent in soil medium . The half life period in case of sediment is 3360 hrs and based on this information it can be concluded that the substance will be non biodegradable in sediment medium. Thus 3a,4,5,6,7,7a-hexahydro-4,7- methanoinden-6-yl acetate would be considered as not persistent in soil and water medium whereas persistent in sediment.
