Additional information
TGEPO was not shown to be readily biodegradable at concentrations of 10 or 20 mg/L. BOD5 results demonstrate ready biodegradability at a concentration of 5 mg/L, and indicate possible inhibition of the inoculum at higher test concentrations. Under standard test conditions, the Chemical Oxygen Demand (COD) for TK 12 184 was determined to be 1559.40 mg Oxygen / g TK 12 184 (Standard Deviation 0.15 %). While these results do not fully meet the ready biodegradability criteria, the weight of available evidence indicates that TK 12 184 is at least inherently biodegradable and not persistent. This is further supported by the US EPA BIOWIN v4.10 model, which predicts this substance to be readily biodegradable.
Conclusion on classification
Based on the available aquatic toxicity and biodegradation data, TGEPO is classified as hazardous to the aquatic environment (Category Chronic 2) according to Regulation (EC) No 1272/2008. This is considered to likely be a case of overclassification based on conservative application of limited data.
