Description of key information

Additional information

Based on the analysis results (IUCLID section 1.4) of a number of representative naphthenic acids samples, a list of potential chemical components was compiled. The log Koc of these structures was estimated with the equation of Di Toro et al. (1985). The log Koc range is 2.02-6.59.

A literature reference reported values for the Kd between 1.3 and 17.8L/kg at 4°C, which corresponds to calculated values of Log Koc of 1.85 to 2.82, corresponding in turn to the lower end of the modelled values.
