The assessment of the environmental effects, exposure and risks of Fatty acids, C16 -18, barium salts is based on the assessment of the individual moieties of the barium carboxylate salt, i.e. the barium ion and the Fatty acids, C16-18.This read-across approach from data for both constituent ions is considered more adequate for the purpose of classification and labelling and environmental risk assessment compared to testing of the registered substance itself:
Based on the following weight of evidence, the risks of fatty acids, C16 -18 are predicted to be negligible and therefore fatty acids C16 -18 are not considered in the effects assessment for its barium salts:
Therefore, the assessment of Fatty acids, C16 -18, barium salt is only based on the barium ion.
For most metal-containing compounds, it is the potentially bioavailablemetal ion that is liberated (in greater or lesser amounts) upon contact with water that is the moiety of ecotoxicological concern. The solubility of fatty acids, C16-18, barium salts (see IUCLID section 4.8) is above the range of effects concentrations for dissolved Ba in the aquatic environment (PNECfreshwater for Ba = 227.8 µg Ba/L) and therefore ecotoxicity data for soluble Ba salts can be directly used in a read-across approach for fatty acids, C16-18, barium salts.
The substance Fatty acids, C16-18, barium salts will dissociate into barium and C16-18 carboxylate ions after dissolution in water and hence can be regarded as a mixture of both constituent ions. In the absence of toxicity data for Fatty acids, C16-18, barium salts itself, its classification for environmental hazards is based on the classification of its moieties (barium and fatty acids, C16-18). Both barium and fatty acids, C16-18 are not classified as hazardous to the aquatic environment, and according to the summation method, it is therefore concluded that the substance Fatty acids, C16-18, barium salts is not hazardous to the aquatic environment.
