The study regarding the toxicity to soil microorganism  for HEBMP-H is waived.

Key value for chemical safety assessment

Additional information

In accordance with Column 2 of the REACH Regulation (EC n.1907/2006) Annex IX, the short-term toxicity test with terrestrial microorganisms (required in Section 9.4.2 of REACH Annex IX) does not need to be conducted as the chemical safety assessment according to Annex I indicates that this is not necessary. In addition, reliable evidence already exists that HEBMP-xNa does not cause inhibition (in the form of total respiration, heterotropic respiration, or nitrification), in aquatic microorganisms (activated sludge) at concentrations up to 1000 mg/l (800 mg/l as active acid equivalent).
