Additional information
By applying weight of evidence approch the number of studies for the test compoundC.I. Pigment Yellow 101(CAS no 2387-03-3) and its predicted data for the adsorption/desorption end point are summarized as below:
The soil adsorption coefficient (Koc) value (EPI suite, 2016) of 1-Naphthalenecarboxaldehyde, 2-hydroxy-, (2-hydroxy-1-naphthalenyl)methylene hydrazone is estimated to be 11130000 L/kg, indicating that it is has a high sorption to soil and sediment and therefore have negligible migration potential to groundwater.
From PBT profiler the soil adsorption coefficient (Koc) value of 1-Naphthalenecarboxaldehyde, 2-hydroxy-, (2-hydroxy-1-naphthalenyl)methylene hydrazone is estimated to be 11000000 L/kg i.e log Koc=7.041, indicating that it is has a Very strong sorption to soil and sediment and therefore have negligible migration potential to groundwater.
In the adsorption/desorption study(Asmaa Mawad; et. al, 2015), a biofilm ofAspergillus terreussupported on activated carbon was used as a biological tool for removal of these dyes from water body. The adsorption kinetics and contact time were determined along 240 minutes (30 minute interval). The initial concentration of dyes was 100 mg/L for each one. The optimum pH value for adsorption process was 3.0. The results depicted that the contact time for biosorption of both dyes was 180 min while adsorption kinetics was quietly fitted with Pseudo second-order kinetics equation models. The maximum adsorption capacity was 78.2 mg/g for Pigment Yellow 101.
The estimated (SciFinder, American Chemical Society (ACS); 2016)koc values for the test chemical measured at 25°C for different values of pH are as follows: 694 at pH =1, 819 at pH=2, 2050 at pH=3, 12200 at pH=4, 45800 at pH=5, 63800 at pH=6, 62500 at pH=7, 37700 at pH=8, 4180 at pH=9, 83.9 at pH=10, respectively.
Overall all studies from predicted models and experimental study indicate that the test substance have tendency to high sorption to soil and sediment and therefore have negligible migration potential to groundwater.
