12.2 Persistence and degradability
AEROBIC: Hexahydrophthalic anhydride reached 4% of its theoretical BOD in 28 days in the Japanese MITI test(1).
12.3 Bioaccumulative potential
An estimated BCF of 13 was calculated in fish for hexahydrophthalic anhydride(SRC), using an estimated log Kow of 2.17(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of hexahydrophthalic anhydride can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that hexahydrophthalic anhydride is expected to have very high mobility in soil.

13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
