Additional information

The primary source of Malachite Green (MG) environmental pollution is represented by industrial waste water and it is very hazardous to the aquatic environment. It has been evaluated that MG is toxic to several aquatic species belonging to different trophic levels like fishes, invertebrates, algae and microorganisms; MG may also have acute, sub-chronic and chronic effects with organ damage or systemic damage.

No data on terrestrial toxicity were available and no terrestrial testing was performed, because direct and indirect exposure of the soil compartment is unlikely. Based on CSR and risk management measures reported there is no soil exposure, thus no specific test is necessary.

There are not direct studies on secondary poisoning, concerned with toxic effects in the higher members of the food chain which result from ingestion of organisms from lower trophic levels that contain accumulated substances, furthermore this process can't be excluded.

Conclusion on classification

Malachite Green (MG) has confirmed the very hazardous to the aquatic environment indicated on the classification of EC Regulation 1272/2008. To have control of environmental risk, it is necessary that all importers, manufacturers and users of the substance, in order to limit leakage into the environment, draw up a series of security measures and operational conditions. Data available confirm the CLP classification as: Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410)
