Additional information

The toxicity of ‘diallyl 2,2'-oxydiethyl dicarbonate’to aquatic organisms (all three trophic levels) has been studied according to a number of reliable guideline methods under GLP and non-GLP conditions. The results of these studies indicate that ‘diallyl 2,2'-oxydiethyl dicarbonate’ is considered as very toxic to aquatic organisms.
