Recent views on river pollution and diatoms

摘要: The first studies of diatoms and river pollution were carried out 60 years ago, the suitability these micro-algae as bioassessment indicators for monitoring quality was quickly demonstrated. objective this review is to describe state art study between 1999 2009. group publications homogeneously according subject indicate which subjects never overlap. To end a lexical analysis conducted on abstract structure seven K-means clusters defined. Most items in area found have been published Hydrobiologia. One (group 6) comprises about discipline (ecotoxicology); several others basis same approaches, example species 3), basin 7), or spatial approaches 2). Other are brought together because used common method using data, namely predictive models 1) biotic indices 4). performed area—South Africa 5). Several remarks can be made. First, ecotoxicological mostly experimental restricted small areas. answer society’s demand new assessment tools micropollutant assessment, next step would more in-situ tests larger scales. Second, diatom biomonitoring uses word “species” extensively, establishing lists flora extensively such Species closely related taxonomy; nevertheless very rarely addressed papers. Third, phylogeny publications. This significant phylogenetic freshwater macroinvertebrates enable appropriate definition taxonomic aggregations that accurate particular environmental stressors.
