Additional information

The lethal concentration (LC50) value of allyl acetoacetatein aquatic invertebrate (Daphnia Magna) in a 48 hr study based on effect on mortality was estimated to be 904.0236mg/L.Thus, considering the CLP Criteria for aquatic classification of the substance , it is concluded that allyl acetoacetatecould not exhibit short term toxicity to aquatic invertebrate (Daphnia Magna).

The various weight of evidence studies can be summarised as follows :
