Description of key information
For iron: the observed 48-hour EC50 on Daphnia magna was >= 100 mg/l. The test was conducted according to guideline OECD 202 (Currenta 2008). Additionally, studies are presented with read across from soluble iron substances. For LEAD: For invertebrates, 43 individual reliable acute toxicity data points for two different species were put forward for hazard assessment purposes. The acute toxicity values (48h-LC50) for Ceriodaphnia dubia varied between of 26.4 µg dissolved Pb/L (at pH 8.1 and hardness of 25 mg/L) and 3115.8 µg dissolved Pb/L (at pH 8.15 and hardness of 103.2 mg/L).The acute toxicity values (48h-LC50) for Daphnia magna varied between of 107.0 µg dissolved Pb/L (at pH 8.3 and hardness of 152 mg/L) and 108.8 µg dissolved Pb/L (at pH 7.6 and hardness of 54 mg/L).
