Water quality. Guidance on methods for sampling invertebrates in the hyporheic zone of rivers
This European Standard provides guidance on methods for sampling invertebrates in the hyporheic zone of wadable rivers. It describes each method, including details of the equipment involved and its use in the field. Guidance is given on developing a sampling strategy and selecting an appropriate survey technique for the purpose of investigation. NOTE Benthic macroinvertebrate sampling is covered by other published standards (see Bibliography). Selected literature with references in support of this document is given in the Bibliography.

Water quality. Guidance on quantitative and qualitative sampling of phytoplankton from inland waters
This European Standard specifies procedures for phytoplankton sampling in inland waters and describes methods of sampling techniques for phytoplankton in inland waters (e. g. rivers and channels, or lakes, ponds, reservoirs and other artificial water bodies, respectively). This European Standard gives guidance for sampling of phytoplankton for qualitative and quantitative limnological investigations and monitoring of water quality, e. g. ecological status.

This International Standard specifies a method for the determination of the acute toxicity to Daphnia magna Straus (Cladocera, Crustacea). This method is applicable to: — chemical substances which are soluble under the conditions of the test, or can be maintained as a stable suspension or dispersion under the conditions of the test; — industrial or sewage effluents; — treated or untreated waste water; — aqueous extracts and leachates; — fresh water (surface and ground water); — eluates of fresh water sediment; — pore water of fresh water sediment.
