Description of key information

Chronic freshwater no-effect levels for dissolved lead for invertebrates were situated between 1.7 µg Pb/L (Lymnaea stagnalis; endpoint: growth) and 182 µg Pb/L (Ceriodaphnia dubia; endpoint: mortality) and the no-effect levels for dissolved lead for marine invertebrates were situated between 95.9 µg Pb/L (Neanthes arenaceodentata; endpoint:: juvenile emergence) and 757 µg Pb/L (Neanthes arenaceodentata; endpoint:: adult survival).

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
1.7 µg/L
EC10, LC10 or NOEC for marine water invertebrates:
95.9 µg/L

Additional information

Since lead is the toxic component and the anions do not contribute to toxicity, all data are grouped together in a read-across approach. Chronic freshwater no-effect levels for dissolved lead for invertebrates were situated between 1.7 µg Pb/L (Lymnaea stagnalis; endpoint: growth) and 182 µg Pb/L (Ceriodaphnia dubia; endpoint: mortality) and the no-effect levels for dissolved lead for marine invertebrates were situated between 95.9 µg Pb/L (Neanthes arenaceodentata; endpoint:: juvenile emergence) and 757 µg Pb/L (Neanthes arenaceodentata; endpoint: adult survival).
