Read-across approach
In the assessment of the environmental fate, ecotoxicity and toxicity of Fatty acids, tall-oil, manganese salts (CAS: 8030-70-4), a read-across approach from data for the metal cation (manganese) and the organic anion (fatty acids, tall-oil) is followed. This read-across strategy is based upon the observation that upon dissolution in aqueous media, Fatty acids, tall-oil, manganese salts completely dissociates and only is present in its dissociated form, i.e. as manganese cation and fatty acids, tall-oil anions. Data on the environmental fate, ecotoxicity and toxicity for both transformation products (manganese cation and fatty acids, tall-oil anions) together can therefore be combined in an additive approach to predict the corresponding properties of Fatty acids, tall-oil, manganese salts.
A detailed justification for the read-across approach is added as a separate document in section 13 of IUCLID.
Upon dissolution and dissociation of Fatty acids, tall-oil, manganese salts into the manganese cation and fatty acids, tall-oil anions, both ions will each show the proper (bio)degradation, bioaccumulation and partitioning behaviour in the environment, as reported for the corresponding ion. The environmental fate and behaviour for the manganese cation and fatty acids, tall-oil anions is predicted to be clearly different from each other, resulting in a different relative distribution over the environmental compartments (water, air, sediment and soil). Because the relative exposure to both constituent ions is hence predicted to be different from the original composition of Fatty acids, tall-oil, manganese salts, data for the ecotoxicological properties of this substance tested as such are considered less relevant for its effects and risk assessment and a read-across approach from data for both the manganese cation and fatty acids, tall-oil anions is preferred. The dose additivity approach is used to explain the ecotoxicological effects of Fatty acids, tall-oil, manganese salts based on the data for the individual transformation products (manganese cation and fatty acids, tall-oil anions).
Conclusion on classification
No reliable ecotoxicological data are available for Fatty acids, tall-oil, manganese salts. The substance will dissociate into manganese and fatty acids, tall-oil 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, tall-oil, manganese salts, its classification for environmental hazards is therefore based on the classification of the transformation products (manganese and fatty acids, tall-oil ions).
Whereas fatty acids, tall-oil has a low potential for acute and chronic toxicity to aquatic organisms, manganese cations, even though essential, appear to be toxic to fish, invertebrates and algae. Thus, reliable data indicate that the moiety of ecotoxicological concern are manganese cations and the lowest respective effect concentrations of manganese for fish, invertebrates, algae are conservatively recalculated for fatty acids, tall-oil, manganese salts based on a maximum manganese content of 9%.
Acute (short-term) toxicity: The lowest EC/LC50 values of 3 trophic levels (algae, invertebrates and fish) for soluble manganese substances are well above 1 mg Mn/L, the classification cut-off value for acute (short-term) aquatic hazard category 1. In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (a), classification for acute (short-term) aquatic hazard is not required for Fatty acids, tall-oil, manganese salts.
(Chronic) long-term toxicity: Reliable chronic aquatic toxicity data of soluble manganese substances are available for algae, crustacea and fish. The lowest respective effect concentration, i.e. the 60-d NOEC of 0.01 mg Mn/L for Macrobrachium rosenbergii (sub(tropical) giant river prawn) derived in the study by Adhikari et al. (2007), is not for a standard invertebrate species and not from a standardised test method and therefore not selected for classification. Thus, the next lowest effect concentration, i.e. the 65-d NOEC of 0.55 mg Mn/L for Salvelinus fontinalis determined in a study equivalent to OECD 210 (Davies et al. 1998), is selected as chronic ecotoxicity reference value.
Based on a maximum manganese content of 9 % of Fatty acids, tall-oil, manganese salts, the recalculation results in a NOEC of 6.1 mg/L Fatty acids, tall-oil, manganese salts that is well above the classification cut-off value for long-term aquatic hazard of 1 mg/L. In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (b) (i), Fatty acids, tall oil, manganese salts does not meet classification criteria of long-term aquatic hazard.
It is concluded that Fatty acids, tall oil, manganese salts does not meet classification criteria of acute (short-term) and long-term aquatic hazard according to Regulation (EC) No 1272/2008 and subsequent adaptations.
