Division 7.2.2.3 Water/sediment study

The information provided, together with other relevant information, shall be sufficient to:

1. (a)

   identify individual components present which at any time account for more than 10 % of the amount of active substance added, including, where possible, non-extractable residues;

2. (b)

   identify individual components present which account for more than 5 % of the amount of active substance added in at least two sequential measurements, where possible;

3. (c)

   identify individual components (> 5 %) for which at the end of the study the maximum of formation is not yet reached, where possible;

4. (d)

   identify or characterise, where possible, also other individual components present;

5. (e)

   establish the relative proportions of the components (mass balance); and

6. (f)

   define the sediment residue of concern, to which non-target species are or may be exposed.

Where a reference is made to non-extractable residues these shall be defined as chemical species originating from active substances used in accordance with good agricultural practice that cannot be extracted by methods which do not significantly change the chemical nature of these residues or the nature of the sediment matrix. These non-extractable residues are not considered to include fragments through metabolic pathways leading to natural products.
