19、ization of terrestrial zoological field methods. Such methods, mainly covering the sampling, extraction and handling of soil invertebrates, are necessary for the following purposes: biological classification of soils including soil quality assessment253139; terrestrial bio-indication and long-term m

20、onitoring111433; evaluation of the effects of chemicals on soil animals (ISO 11268-3).Data for these purposes are gained by standardized methods since they can form the basis for far-reaching decisions (e.g. whether a given site should be remediated or not). In fact, the lack of such standardised me

21、thods is one of the most important reasons why bio-classification and bio-assessment in terrestrial (i.e. soil) habitats has so far relatively rarely been used in comparison to aquatic sites.Since it is neither possible nor useful to standardize methods for all soil organisms, the most important one

22、s have been selected. In this document sampling of earthworms is described.Originally, the methods described in this document were developed for taxonomical and ecological studies, investigating the role of earthworms in various soil ecosystems. These animals are without doubt the most important soi

23、l invertebrates in temperate regions and, to a lesser extent, in boreal and tropical soils301618. Since Darwin (1881) (see Reference 8), their influence on soil structure (e.g. aeration, water holding capacity) and soil functions like litter decomposition and nutrient cycling is well-known10. Due to

24、 their often very high biomass they are also important in many terrestrial food-webs.In the previous version of this document the chemical formalin was recommended as extraction fluid. However, within the last years evidence increased that formalin does have critical properties, mainly in terms of h

25、uman toxicity. In December 2012, the Risk Assessment Committee (RAC) of the European Chemicals Agency (ECHA) stated that there is sufficient scientific evidence to classify this chemical as “probably carcinogenic for humans (Category Ib). In addition, negative effects on non-target organisms (includ

26、ing soil microorganisms, mesofauna and plants) have been reported (e.g. see Reference 7). Therefore, this substance has been replaced.Due to the growing reservations against the use of formalin, several alternatives have been studied. In Reference 40 allyl isothiocyanate (AITC) was tested for its ef

27、fectiveness as a chemical expellant for sampling earthworms. AITC is a natural breakdown product of glucosinolates in many Cruciferae, i.e. it is the component imparting the sharp taste of mustard. According to the European Chemical Agency (ECHA), there is no concern regarding its use under outdoor

28、conditions.Over the last years, some studies have been performed in which the extraction efficiency of formalin and AITC were compared at the same sites and dates. According to Reference 22 no differences were found in numbers or biomass of earthworms extracted at crop sites when using either formal

29、in or AITC as extractant. In a recent unpublished review (see Reference 28) no significant differences were reported in earthworm numbers/biomass when comparing the efficiency of the two extraction chemicals. Also, no interaction was found on the sampling sites between the extractant and the site, i

30、ndicating that no site-specific differences were observed in extraction efficiency of the extractants. When plotting the correlation between worm numbers extracted with AITC versus formalin in a Bland-Altman graph (a common way to compare a gold-standard method to an alternative method in the medica

31、l sciences), no significant bias of the AITC method as compared to the formalin method was found, indicating the similarity / exchangeability of the two methods.Basic information on the ecology of earthworms and their use as bioindicators in the terrestrial environment can be found in the references

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
