(Springer, 2016-07-12)
Purpose This study aimed at evaluating the acute effects of arsenic and zinc to the warmwater aquatic oligochaete Branchiura sowerbyi. Relative sensitivity with the coldwater species Tubifex tubifex was compared. Implications ...
Derivation of sediment Hg quality standards based on ecological assessment in river basins
(Elsevier, 2018-11-28)
The Environmental Quality Standards (EQS) directive was an important improvement of long-term water quality monitoring at the European level, leading to the use of sediments and biota as relevant matrices for assessing ...
Sensitivity of macroinvertebrate indicator taxa to metal gradients in mining areas in Northern Spain
(Elsevier, 2018-04-24)
The study of macroinvertebrate communities using a Reference Condition Approach (RCA) is a powerful tool for detecting the impacts of mining activities due to heavy metal contamination in rivers. However, studies on this ...
Baseline tissue levels of trace metals and metalloids to approach ecological threshold concentrations in aquatic macroinvertebrates
(Elsevier, 2018-04-24)
Within the framework of the European Environmental Quality Standards Directive, the biota was recognized as a suitable matrix for monitoring water quality. In the Nalón River basin (North Spain), a catchment subject to ...
