Division 2.8.2 Where there is a possibility of aquatic organisms being exposed, no authorisation shall be granted if:

the micro-organism is pathogenic to aquatic organisms,

in case of toxic effects due to components in the plant protection product such as relevant metabolites/toxins, the toxicity/exposure ratio is less than 100 in case of acute toxicity (EC₅₀) to daphnia and fish and 10 for long-term/chronic toxicity to algae (EC₅₀), daphnia (NOEC) and fish (NOEC), unless it is clearly established through an appropriate risk assessment that under field conditions no unacceptable impact on the viability of exposed species occurs — directly or indirectly — after use of the plant protection product according to the proposed conditions of use.
