Popis: | Background, Aim and Scope Background, Aims and Scope. The earthworm field test firstly was developed by the German Federal Biological Research Centre for Agriculture and Forestry (BBA) for testing of pesticides and later internationally standardised by the International Organization for Standardization (ISO) as a tool for characterizing soil quality. It is mainly used for the assessment of effects of pesticides on earthworms under field conditions. Growing experience has shown that the practical performance of the test can be improved. Main Features: In two meetings organised by the Federal Biological Research Centre for Agriculture and Forestry (Braunschweig, 2002) and later the German Federal Agency for Consumer Protection and Food Safety (Lille, 2005) an ad-hoc working group of experts from various countries and institutions discussed the practical performance and recommendations that should be taken into account in a revised draft following the current ISO guideline after the proposed revision has been approved by voting in the periodical review. Results: The outcome of the discussions and the background of the recommendations of the ad-hoc working group are briefly summarised in this paper. These are mainly methodological details in order to improve the test performance (e.g. by decreasing variability or increasing practicability). Discussion: These recommendations are proposed to be considered for the next update of the current ISO guideline. They should be seen as technical amendments still waiting for their approval by standardisation organisations. Conclusions: Although this method focuses on the assessment of effects of pesticides on earthworms, the recommendations will also be valuable for testing contaminated soils. The recommendations presented may also be a first step for splitting the current guideline into two fields of application, one for testing of chemicals and pesticides (i.e. within the scope of OECD) and another one for testing soil quality (i.e. within the scope of ISO). Perspectives: Nevertheless, there is still a major need for guidance concerning the interpretation of effects determined in such complex field tests. |
