Short-term toxicity of hexavalent-chromium to epipsammic diatoms of a microtidal estuary (Río de la Plata): Responses from the individual cell to the community structure

Comparative evaluation of short-term stress of Cd(II), Hg(II), Pb(II), As(III) and Cr(VI) on anammox granules by batch test

“…However, when Cr(VI) concentration exceeding the sludge resistance capacity, the anammox activity was almost fully inhibited. This phenomenon of Cr(VI) inhibition has also been discovered by others (23,24), but the reason still remains unclear. Based on the regression equation (Eq.…”

Ferronickel slag toxicity tests on Chlorella vulgaris and Artemia sp.

“…Eventually, due to reduced chlorophyll content, photosynthesis is inhibited and therefore contributes to reduced growth of C. vulgaris (D'ors, Pereira, Bartolome, Lopez-Rodas, Costas, & Sanchez-Fortun, 2010). In addition, exposure to Cr ions can also cause structural changes in the cell nucleus that affect the growth of algal symbionts (Licursi and Gomez, 2013).…”

Effects of organic pollution on biological communities of marine biofilm on hard substrata

“…Biofilms can accumulate pollutants (Morin et al, 2008;Sanz-Lazaro et al, 2011b), which is proven to induce changes in the biological assemblages in freshwater systems (Dorigo et al, 2007;Sabater et al, 2007). In marine environments, metal and pesticide pollution alter the species composition of biofilm communities (Magnusson et al, 2012;Licursi and Gomez, 2013), but these effects have been much less studied compared to freshwater systems (Sabater et al, 2007).…”
