Additional information

The BCF was estimated using accepted calculation methods.

EPA BCFBAF v.3.01 gives a value of 3.16 L/Kg ww for the corresponding hydrolysis product,methylbicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic acid (METHAc).

These are in line with experimental data which resulted in a range 3.9 - 5.5

It is therefore concluded that the potential for bioaccumulation of 1,2,3,6-tetrahydromethyl-3,6-methanophthalic anhydride (METH) is low.
