Description of key information

Bioaccumulation in aquatic/sediments:

Using Bio-concentration Factor (v12.1.0.50374) module Bio-concentration Factor at range pH 1-14  of the chemical 1,4-diamino-2,3-dichloroanthraquinone (CAS no.81-42-5) estimated to be 11037 dimensionless. This value indicates that the chemical 1,4-diamino-2,3-dichloroanthraquinone is very bioaccumulative in aquatic organisms as this value exceeds 2000 criteria.

Additional information

Bioaccumulation in aquatic/sediments:

Predicted data for target chemical 1,4-diamino-2,3-dichloroanthraquinone (CAS no.81-42-5) from two different sources were reviewed for bioaccumulation endpoint and their results are summarized below.

In a prediction done by using Bio-concentration Factor module (v12.1.0.50374) of Advanced Chemistry Development/ I lab predictive module the bio-concentration Factor at range pH 1-14  of the chemical 1,4-diamino-2,3-dichloroanthraquinone (CAS no.81-42-5) estimated to be 11037 dimensionless. This value indicates that the chemical 1,4-diamino-2,3-dichloroanthraquinone is very bioaccumulative in aquatic organisms as this value exceeds 2000 criteria.

Another prediction done by using SciFinder database of American Chemical Society (ACS, 2017) the Bioconcentration factor (BCF) for test chemical 1,4-diamino-2,3-dichloroanthraquinone (CAS No: 81-42-5) was predicted in aquatic organisms at pH 1-10 and temperature 25 °C .The Bioconcentration factor (BCF) of test substance 1,4-diamino-2,3-dichloroanthraquinone at pH 1-10 and temperature 25 °C was estimated to be 4030 dimensionless. This BCF value at pH 1-10 and temperature 25 °C suggests that the test chemical 1,4-diamino-2,3-dichloroanthraquinone is bioaccumulative in aquatic organisms as this value exceeds 2000 criteria.

On the basis of results of both predicted data for target chemical1,4-diamino-2,3-dichloroanthraquinone (CAS no.81-42-5) it is concluded that this test chemical is bioaccumulative in aquatic organisms.
