英文名称：Soil quality — Sampling of soil invertebrates — Part 3: Sampling and extraction of enchytraeids
发布日期：2019-08
标准范围
This document specifies a method for sampling, handling and extracting enchytraeids from terrestrial
field soils as a prerequisite for using these animals as bioindicators (e.g. to assess the quality of a soil as
a habitat for organisms).
Basic information on the ecology of enchytraeids and their use as bioindicators in the terrestrial
environment is included in the Bibliography.
This document applies to all terrestrial biotopes in which enchytraeids occur. The sampling design of
field studies in general is given in ISO 18400-101. These details can vary according to the climatic/
regional conditions of the site to be sampled and an overview on the determination of effects of
pollutants on enchytraeids in field situations is given in Reference [6].
Methods for some other soil organism groups such as earthworms or arthropods are given in
ISO 23611-1, ISO 23611-2, ISO 23611-4 and ISO 23611-5.
This document is not applicable for very wet or flooded soils and might be difficult to use under extreme
climatic or geographical conditions (e.g. in high mountains).
When sampling soil invertebrates, it is highly recommendable to characterize the site (e.g. concerning
soil properties, climate and land use). However, such a characterization is not covered by this document.
ISO 10390, ISO 10694, ISO 11272, ISO 11274, ISO 11277, ISO 11461 and ISO 11465 are more suitable for
measuring pH, particle size distribution, C/N ratio, organic carbon content and water-holding capacity.
