Division 2.8.5.2 A plant protection product may give rise to toxic effects due to the action of toxins or co-formulants. For the assessment of such effects the following information should be taken into consideration:

1. (a)

   studies on earthworm toxicity,

2. (b)

   information on fate and behaviour in the various parts of the environment.

If mortality or signs of intoxication are observed in the tests the evaluation must include a calculation of toxicity/exposure ratios based on the quotient of the LC₅₀ value and the estimated exposure expressed in mg/kg dry weight soil.
