Water Quality - Design And Use Of Quantitative Samplers For Benthic Macro-invertebrates On Stony Substrata In Shallow Freshwaters
出版:Asociacion Espanola de Normalizacion

专家解读视频
Describes biological testing for benthic macroinvertebrates by sampling fresh waters up to one metre deep over stoney substrata. The procedures apply to the sampling of all accessible aquatic habitats in estuaries, streams and rivers where current velocities over 0,1 m/s may be expected, but the samplers, with modifications, may be used in locations of low current velocity, such as lakes and ponds. Coverage includes apparatus and diagrams.
