A summary and evaluation of all data relevant to the environmental impact, should be carried out according to the guidance given by the competent authorities of the Member States concerning the format of such summaries and evaluations. It should include a detailed and critical assessment of those data in the context of relevant evaluative and decision making criteria and guidelines, with particular reference to the risks for the environment and non-target species that may or do arise, and the extent, quality and reliability of the data base. In particular the following issues should be addressed:

• distribution and fate in the environment, and the time courses involved,

• identification of non-target species and populations at risk, and the extent of their potential exposure,

• identification of precautions necessary to avoid or minimise contamination of the environment, and for the protection of non-target species.
