Description of key information

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 persistence time of 414 hr. Since it is considered that a substance will qualify as not persistent if the period does not exceed the EPA criteria .So, it can be confirmed that the substance is readily biodegradable in nature. The half life period of 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate in water is 360 hrs and based on this value it is indicated that the chemical is not persistent in environment.

Key value for chemical safety assessment
