The choice of the appropriate test(s) will depend on the results of the chemical safety assessment.\nThe long-term aquatic toxicity study on fish (Annex IX, Section 9.1.6) shall be considered if the substance is poorly water soluble, or for nanoforms if they have low dissolution rate in the relevant test media.\n9.1.4.\nActivated sludge respiration inhibition testing\n9.1.4.\nThe study does not need to be conducted if:\nthere is no emission to a sewage treatment plant, or\nthere are mitigating factors indicating that microbial toxicity is unlikely to occur, for instance the substance is highly insoluble in water, or\nthe substance is found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of a sewage treatment plant.\nFor nanoforms, the study may not be waived on the basis of high insolubility in water alone.\nThe study may be replaced by a nitrification inhibition test if available data show that the substance is likely to be an inhibitor of microbial growth or function, in particular nitrifying bacteria.\n9.2.\nDegradation\n9.2.\nFurther degradation testing shall be considered if the chemical safety assessment according to Annex I indicates the need to investigate further the degradation of the substance.\nFor nanoforms that are not soluble, nor have high dissolution rate, such test(s) shall consider morphological transformation (e.g. irreversible changes in particle size, shape and surface properties, loss of coating), chemical transformation (e.g. oxidation, reduction) and other abiotic degradation (e.g. photolysis).\nThe choice of the appropriate test(s) will depend on the results of the chemical safety assessment.\n9.2.2.\nAbiotic\n9.2.2.1.\nHydrolysis as a function of pH.\n9.2.2.1.\nThe study does not need to be conducted if:\nthe substance is readily biodegradable, or\nthe substance is highly insoluble in water.\nFor nanoforms, the study may not be waived on the basis of high insolubility in water alone.\n9.3. Fate and behaviour in the environment\n9.3.1.\nAdsorption/desorption screening\n9.3.1.\nThe study does not need to be conducted if:\nbased on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol-water partition coefficient), or\nthe substance and its relevant degradation products decompose rapidly.\nFor nanoforms, use of any physicochemical property (e.g. octanol-water partition coefficient) as a reason for waiving the study shall include adequate justification of its relevance to low potential for adsorption.",
