Aim of the tests
The information and data provided, taken together with that provided for one or more preparations containing the active substance, and other relevant information, should be sufficient to establish, or permit estimation of:
persistence in water systems (bottom sediment and water, including suspended particles),
the extent to which water, sediment organisms and air are at risk,
potential for contamination of surface water and groundwater.
Aim of the tests
The data and information provided, together with other relevant data and information, should be sufficient to:
identify the relative importance of the types of processes involved (balance between chemical and biological degradation),
where possible, identify the individual components present,
establish the relative proportions of the components present and their distribution as between water, including suspended particles, and sediment, and
permit the residue of concern and to which non-target species are or may be exposed, to be defined.
Circumstances in which required
The test must always be performed for relevant metabolites, degradation and reaction products which account at any time for more than 10 % of the amount of active substance added unless sufficient information on their degradation is available from the test performed in accordance with point 2.9.1.
Test conditions and test guideline
The same provisions as provided under the corresponding paragraphs of point 2.9.1 apply.
Circumstances in which required
The test must always be performed for relevant metabolites, degradation and reaction products which account at any time for more than 10 % of the amount of active substance added unless sufficient information on their degradation is available from the test performed in accordance with points 2.9.2 and 2.9.3.
Test conditions and test guideline
The same provisions as provided under the corresponding paragraphs of points 2.9.2 and 2.9.3 apply.
Circumstances in which required
The test must always be performed unless it is not required under the provisions of Annex VI to Directive 67/548/EEC for the classification of the active substance.
Test guideline
EEC method C4.
Circumstances in which required
The test must be reported unless it can be justified that contamination of surface water will not occur.
Test guideline
SETAC — Procedures for assessing the environmental fate and ecotoxicity of pesticides.
Circumstances in which required
Transformation rates in the saturated zone of active substances and of relevant metabolites, degradation and reaction products can provide useful information on the fate of these substances in the groundwater.
Test conditions
Expert judgement is required to decide whether this information is necessary. Before performing these studies the applicant shall seek the agreement of the competent authorities on the type of study to be performed.
