Conclusion on classification
The available toxicity data: to fish (48h LC50 = 160 mg/l), to Daphnia (48h EC50=162.2 mg/l), to frog larvae (96h tox test = 4020 mg/l) show a low toxicity level. Oxalic acid has a low logKow and is readily biodegradable.The substance is not be classified as hazardous for the environment.
