Description of key information
Bioaccumulation: aquatic / sediment
BCFBAF model of Estimation Programs Interface (2018) was used to predict the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 241.9 L/kg whole body w.w (at 25 deg C) which does not exceed the bio concentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
Additional information
Bioaccumulation: aquatic / sediment
Various predicted data of the test chemical and supporting weight of evidence studies for its structurally similar read across chemical were reviewed for the bioaccumulation end point which are summarized as below:
In a prediction done using the BCFBAF Program of Estimation Programs Interface was used to predict the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 241.9 L/kg whole body w.w (at 25 deg C) which does not exceed the bio concentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
In an another prediction done by using Bio-concentration Factor module (ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017)), Bio-concentration Factor of the test chemical was estimated to be 164 at pH range 1-14, respectively. This value indicates that the test chemical was considered to be non-accumulative in aquatic organisms.
Bioconcentration Factor (BCF) of test chemical was estimated using Chemspider database (modelling database, 2017). The bioconcentration factor of test chemical was estimated to be 127.02 at pH both 5.5 and 7.4, respectively, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
Another predicted data was estimated using SciFinder database (American Chemical Society (ACS), 2017) for predicting the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 54.2 at pH range 1-10 respectively (at 25 deg C) which does not exceed the bio concentration threshold of 2000, indicating that the test 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 chemical was estimated to be 21.6 dimensionless . The predicted BCF result based on the 5 OECD principles. Thus based on the result it is concluded that the test chemical is non-bioaccumulative in nature.
In a supporting weight of evidence study from authoritative database (2017), bioaccumulation experiment was conducted on test organism Cyprinus carpio for 28 days for evaluating the bioconcentration factor (BCF value) of test chemical. The study was performed according to "OECD Guideline 305 (Bioconcentration: Flow-through Fish Test)" and other guideline "Bioaccumulation test of a chemical substance in fish or shellfish" provided in "the Notice on the Test Method Concerning New Chemical Substances", respectively. Cyprinus carpio was used as a test organism for the study. Test chemical nominal conc. used for the study was 1mg/land 0.1 mg/l, respectively. Analytical method involve the recovery ratio: Fish : 87.5 %, - Limit of quantitation : Test water : 1st concentration area : 31 microg/L, 2nd concentration area : 3.1 microg/L, Fish : 340 ng/g. Range finding study involve the LC50 (96 h) 270 mg/l on Rice fish (Oryzias latipes). Lipid content of the test organism was determined to be 2.14% and 2.05% at the start and end of exposure. The bioconcentration factor (BCF value) of test chemical on Cyprinus carpio was determined to be ≤ 0.34 L/Kg at a conc. of 1 mg/l and ≤ 3.5 L/Kg at a conc. of 0.1 mg/l, respectively.
For the test chemical,bioaccumulation study was conducted on test organism Cyprinus carpio for 8 weeks for evaluating the bioconcentration factor (BCF value) of test chemical under static conditions (J-CHECK, 2017). The study was performed according to other guideline "Bioaccumulation test of a chemical substance in fish or shellfish" provided in "the Notice on the Test Method Concerning New Chemical Substances". Test chemical nominal conc. used for the study were 5 mg/l and 0.5 mg/l (w/v), respectively. Range finding study involve the TLm (48 hr) 610 mg/l on Rice fish (Oryzias latipes). The bioconcentration factor (BCF value) of test chemical on Cyprinus carpio was determined to be < 0.6 L/Kg at a conc. of 5 mg/l and < 6 L/Kg at a conc. of 0.5 mg/l, respectively.
On the basis of above results for test chemical, it can be concluded that the BCF value of test chemical was evaluated to be ranges from upto 241.9, respectively, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
