Conclusion on classification

As the substance is a gas, aquatic toxicity studies are technically not feasible. In the absence of measured data, estimated effect concentrations were predicted using the QSAR, ECOSAR v1.11. Carbon monoxide was predicted to have low toxicity to aquatic organisms, with the lowest effect concentration reported to be an EC50 of 124.4 mg/L to algae. Based on this, carbon monoxide is not classified as hazardous to the environment.
