BS EN 16150 gives guidance on procedures for the pro-rata Multi-Habitat-Sampling (MHS) of benthic macro-invertebrates in wadeable rivers and streams. The term "pro-rata" reflects the intention to sample adequate proportions of riverine habitats with reference to their percentage occurrence.
The pro-rata MHS technique does not replace other techniques, but is rather, alongside other applications, a fundamental requisite of some multi-metric assessment approaches used to evaluate the ecological status of running waters.
The method described in BS EN 16150 is one of the possible techniques among the existing pro-rata MHS techniques.
The MHS methodology is based on Rapid Bioassessment Protocols [1], the procedures of the Environment Agency for England and Wales [2], the Austrian Guidelines for the Assessment of the Saprobiological Water Quality of Rivers and Streams [3], the AQEM sampling manual [4], the AQEM & STAR site protocol [5], EN 27828, the Austrian Standards M 6232 and M 6119-2 [6], [7], the German Standard DIN 38410-1 [8] and the French Standard XP T90-333 [9].
BS EN 16150 also describes in a detailed manner how to sample different habitats that might be suitable for sampling approaches other than Multi-Habitat-Sampling.
BS EN 16150 on multi-habitat sampling of benthic macro-invertebrates is useful for:
The method focuses on a multi-habitat approach, designed for sampling major habitats in proportion to their presence within a sampling reach.
BS EN 16150 guides sampling, preservation, and storing for analysis of benthic macroinvertebrates from wadeable rivers using pro-rata multi-habitat sampling. It provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The test methods and procedures provided by BS EN 16150 assist you in getting complete information for a sampling of benthic macroinvertebrates from wadeable rivers to insure ensure reducing the risk of severe health issues.
With compliance to BS EN 16150, you can enhance the efficacy of the water and manufacture a standardized product.
