Description of key information

Bioaccumulation: aquatic / sediment

Bioconcentration Factor (BCF) of test chemical (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate (CAS no. 57082 -24 -3) was estimated using Chemspider database. The bioconcentration factor of test substance (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate was estimated to be 6412.87 at pH both 5.5 and 7.4, respectively, which exceeds the bioconcentration threshold of 5000, indicating that the chemical (1R-(1alpha,2alpha,5beta,8beta))-4,4,8 -Trimethyltricyclo[6.3.1.02,5] dodecanyl acetate is expected to very bioaccumulate in the food chain.

Additional information

Various predicted data for the target compound (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate (CAS No. 57082-24-3) were reviewed for the bioaccumulation end point which are summarized as below:

 

Bioconcentration Factor (BCF) of test chemical (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate (CAS no. 57082 -24 -3) was estimated(ChemSpider, 2017). The bioconcentration factor of test substance (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate was estimated to be 6412.87 at pH both 5.5 and 7.4, respectively.

 

Another predicted data was estimated usingSciFinder database (American Chemical Society (ACS), 2017) was used for predicting the bioconcentration factor (BCF) of test chemical (1R-(1alpha,2alpha,5beta,8beta))-4,4,8 -Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate (CAS No. 57082 -24 -3). The bioconcentration factor (BCF) of (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate was estimated to be 8040 at pH range 1-10, respectively (at 25 deg C).

 

On the basis of above results for target chemical (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate (from ChemSpider and SciFinder database,  2017), it can be concluded that the BCF value of test substance (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate ranges from 6412.87 –8040,which does exceeds the bioconcentration threshold of 5000, indicating that the chemical (1R-(1alpha,2alpha,5beta,8beta))-4,4,8-Trimethyltricyclo[6.3.1.02,5]dodecanyl acetate is expected to very bioaccumulate in the food chain.
