Ready Biodegradability Prediction: (YES or NO)

----------------------------------------------

Criteria for the YES or NO prediction: If the Biowin3 (ultimate survey

model) result is "weeks" or faster (i.e. "days", "days to weeks", or

"weeks" AND the Biowin5 (MITI linear model) probability is >= 0.5, then

the prediction is YES (readily biodegradable). If this condition is not

satisfied, the prediction is NO (not readily biodegradable). This method

is based on application of Bayesian analysis to ready biodegradation data

(see Help). Biowin5 and 6 also predict ready biodegradability, but for

degradation in the OECD301C test only; using data from the Chemicals

Evaluation and Research Institute Japan (CERIJ) database.

 

Biodegradation in water and sediment: simulation tests

 

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE”, a ready biodegradability study does not need to be performed if the substance is ready biodegradable. As magnesium is ready biodegradable a ready biodegradability study does not need to be conducted.

The estimated Biodegradetion was measured by calculation from EPI SuiteTM v4.0 Program and Biodegradation was predicted . This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency) .
