Description of key information

According to column 2 of REACH Annex VII, a study on short term toxicity on aquatic invertebrates does not need to be conducted if relevant information for environmental classification and labeling is available. According to 67/548/EEC Lead  acetate is classified as dangerous for the environment (R50/53; R51/53, and R52/53). According to CLP Lead acetate is classified for its acute and chronic aquatic toxicity (aquatic acute and aquatic chronic category 1,  H410, H410). Therefore, a study on short term toxicity on aquatic invertebrates is not required.

Additional information

According to column 2 of REACH Annex VII, a study on short term toxicity on aquatic invertebrates does not need to be conducted if relevant information for environmental classification and labeling is available. According to 67/548/EEC Lead acetate is classified as dangerous for the environment (R50/53). According to CLP Lead (II) nitrate is classified for its acute and chronic aquatic toxicity (category 1, H410).Several studies have been conducted and reviewed. Appraisal taken from International Programme on chemical Safety, Environment Health Criteria 85, Lead - Environmental aspects (see attachment to summary in section 6.1).

The results of experiments on the toxicity of lead salts to aquatic invertebrates  are difficult  to interpret  due to  the  variations in experimental  conditions and  the lack  of a  standardized  method  for determining  lead concentrations in  water.  In most  studies,  concentrations  of lead in water are nominal; the contribution to toxicity of factors,  such as  pH, water  hardness, anions,  and complexing  agents cannot be fully evaluated..
