Description of key information

Bioaccumulation: aquatic/sediment

BCFBAF model (v3.01) of Estimation Programs Interface (EPI Suite, 2017) was used to predict the bioconcentration factor (BCF) of test chemical 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid (CAS No. 91 -29 -2). The bioconcentration factor (BCF) of 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid was estimated to be 3.162 L/kg whole body w.w (at 25 deg C) which does not exceed the bioconcentration threshold of 2000, indicating that the chemical 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid is not expected to bioaccumulate in the food chain.

Additional information

Bioaccumulation: aquatic/sediment

Various predicted data for the target compound 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid (CAS No. 91-29-2) were reviewed for the bioaccumulation end point which are summarized as below:

 

Using the BCFBAF Program(v3.01) of Estimation Programs Interface (EPI Suite, 2017) the bioconcentration factor (BCF) of 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid was estimated to be 3.162 L/kg whole body w.w (at 25 deg C) which does not exceed the bioconcentration threshold of 2000, indicating that the chemical 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid is not expected to bioaccumulate in the food chain.

 

In an another prediction done by using Bio-concentration Factor (v12.1.0.50374) module, the BCF over the entire pH scale (pH 0 - 14) of the test substance 2-[(4-aminophenyl) amino]-5-nitrobenzenesulfonic acid (CAS no. 91 -29 -2) was estimated to be 1. This value indicates that the substance 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid was considered to be non-accumulative in aquatic organisms.

 

Bioaccumulation test was conducted for estimating the bioconcentration factor (BCF) of test chemical 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid (CAS no. 91 -29 -2)(ChemSpider, 2017). The bioconcentration factor (BCF) of 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid was estimated to be 1 at pH 5.5 and 7.4, respectively, which does not exceed the bioconcentration threshold of 2000, indicating that the chemical 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid is not expected to bioaccumulate in the food chain.

 

Another predicted data was estimated usingSciFinder database (American Chemical Society (ACS), 2017) was used for predicting the bioconcentration factor (BCF) of test chemical 2 -[(4 -aminophenyl)amino]-5 -nitrobenzenesulfonic acid (CAS No. 91 -29 -2). The bioconcentration factor (BCF) of 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid was estimated to be 1 (at 25 deg C) which does not exceed the bio concentration threshold of 2000, indicating that the chemical is not expected to bioaccumulate in the food chain.

 

From CompTox Chemistry Dashboard using OPERA (OPEn (quantitative) structure-activity Relationship Application)  V1.02 model in which calculation based on PaDEL descriptors (calculate molecular descriptors and fingerprints of chemical)  the bioaccumulation i.e BCF for test substance 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid was estimated to be 5.53 dimensionless . The predicted BCF result based on the 5 OECD principles. Thus based on the result it is concluded that the test substance 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid is non-bioaccumulative in nature.

 

On the basis of above results for target chemical2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid(from EPI suite, ACD labs,ChemSpider, SciFinder database and CompTox Chemistry Dashboard,  2017), it can be concluded that the BCF value of test substance2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid ranges from 1 – 5.53 which does not exceed the bioconcentration threshold of 2000, indicating that the chemical 2-[(4-aminophenyl)amino]-5-nitrobenzenesulfonic acid is not expected to bioaccumulate in the food chain.
