  • However, in accordance with section 1 of REACH Annex XI, studies on terrestrial organisms do not need to be conducted, as the members of the category 'poorly soluble iron (hydr)oxides' are inert inorganic (hydr)oxides of iron, which resemble naturally occurring iron (hydr)oxides, and based upon the physico-chemical properties and low bioavailability of the substances. (europa.eu)
  • Even under worst case conditions, an inhibitory effect of poorly soluble iron (hydr)oxides is not likely to be exerted on soil organisms. (europa.eu)
