Key value for chemical safety assessment

Additional information

Due to the low water solubility of C. I. Pigment Yellow 34 adverse chronic effects of the substance to aquatic organisms are not expected. However, a minor part of the substance may dissolve and chromate (CrO42-) and lead ions (Pb²+) may dissociate from the parent substance. Both substances may have chronic effects on aquatic invertebrates.
