A read-across approach was used from data for soluble Pb salts without concern on the toxicity of the accompanying anion. All reliable toxicity data selected for calculation of the PNEC were derived from soils spiked with soluble lead salts (such as lead chloride, lead acetate and lead nitrate). All results were based on elemental Pb concentrations, allow-ing straight comparison of the results and read-across to other Pb substances. Fourteen reliable chronic NOEC or EC10 values for 5 annelid worm species were selected for PNEC derivation. Selected values range from 64 mg Pb/kg dw for reproduction of Eisenia fetida to 2445 mg Pb/kg dw for mortality of Aporrectodea caliginosa.
