NOEC = 20 mg/L
data are available on the registered substance itself. However, data are
available on three structural analogues of the substance, which after
considering the differences in molecular weight, lead to comparable NOEC
values. The best quality data originates from a recent study with
methyl-tetrahydrophthalic anhydride (MTHPA). The NOEC from this study
was 20 mg/L which, when corrected for differences in molecular weight,
results in a calculated NOEC of 20 mg/L for 4 -MHHPA.
