Adsorption / desorption:
Experimental and Predicted data of adsorption endpoint for the target chemical 4-aminonaphthalene-1,8-dicarboximide (Cas no. 1742-95-6) and its read across chemical were reviewed to summarize as follows:
From predicted model EPI suite 2016 indicate that the soil adsorption coefficient (Koc) value of chemical 4-aminonaphthalene-1,8-dicarboximide is estimated to be 24.82 L/kg (log KOC = 1.3948) by means of MCI method at 25 deg.C, indicating that it is has a Negligible sorption to soil and sediment and therefore have rapid migration potential to groundwater.
Whereas from chemspider predicted database the soil adsorption coefficient i.e Koc value of test substance 4-aminonaphthalene-1,8-dicarboximide was estimated to be 68.40 L/Kg i.e Log Koc= 1.835 at pH 5.5 and 67.90 L/Kg i.e Log Koc= 1.831 at pH 7.4. This Koc value indicates that the substance 4-aminonaphthalene-1,8-dicarboximide has a Negligible sorption to soil and sediment and therefore have rapid migration potential to groundwater.
And read across Phthalimide (Cas no. 85-41-6)experimental study from HSDB authorative database indicate that the adsorption coefficient (Koc) of substance Phthalimide was found to be 100 using an experimental log Kow of 1.15 and a regression-derived equation. This Koc value suggests that phthalimide should have high mobility in soil.
Thus based on the above all studies it is concluded that the test substance 4-aminonaphthalene-1,8-dicarboximide (Cas no. 1742-95-6) has a Negligible sorption to soil and sediment i.e have high mobility to soil/ sediment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
