Algal photosynthetic responses to toxic metals and herbicides assessed by chlorophyll a fluorescence
TL;DR: The present review demonstrates the applicability of chlorophyll a fluorescence in determining photochemical responses of algae exposed to environmental toxicants (such as toxic metals and herbicides) as an excellent alternative for detecting pollution.
Journal ArticleDOI
Separate treatment of hospital and urban wastewaters: A real scale comparison of effluents and their effect on microbial communities.
Teofana Chonova,Teofana Chonova,François Keck,Jérôme Labanowski,Bernard Montuelle,Frédéric Rimet,Agnès Bouchez +6 more
TL;DR: According to the removal efficiency of pharmaceuticals, the separate treatment was beneficial, however, their high concentrations in the HTE and the following adaptations of biofilm communities identify the importance of adapting wastewater treatment to specific hospital pollutants.
Journal ArticleDOI
Effects of flow intermittency and pharmaceutical exposure on the structure and metabolism of stream biofilms.
Natàlia Corcoll,Maria Casellas,Belinda Huerta,Helena Guasch,Vicenç Acuña,Sara Rodríguez-Mozaz,Albert Serra-Compte,Damià Barceló,Damià Barceló,Sergi Sabater,Sergi Sabater +10 more
TL;DR: The effects of a long-term exposure of biofilm communities to a mixture of pharmaceutical compounds at environmental concentrations on biofilm bioaccumulation capacity, the structure and metabolic processes of algae and bacteria communities, and how their potential effects were enhanced or not by the occurrence of flow intermittency are evaluated.

Pollution-induced community tolerance to non-steroidal anti-inflammatory drugs (NSAIDs) in fluvial biofilm communities affected by WWTP effluents
Natàlia Corcoll,Vicenç Acuña,Damià Barceló,Damià Barceló,Maria Casellas,Helena Guasch,Belinda Huerta,Mira Petrovic,Mira Petrovic,Lídia Ponsatí,Sara Rodríguez-Mozaz,Sergi Sabater,Sergi Sabater +12 more
TL;DR: Tolerance acquired by stream biofilms to two non-steroidal anti-inflammatory-drugs, ibuprofen and diclofenac was assessed and it was observed that the chronic pollution by the WWTP effluent affected the microbial metabolic profile, as well as the structure of the algal community.

A modified single solution method for the determination of phosphate in natural waters
J. Murphy,J.P. Riley +1 more
TL;DR: In this article, a single solution reagent was described for the determination of phosphorus in sea water, which consists of an acidified solution of ammonium molybdate containing ascorbic acid and a small amount of antimony.
Journal ArticleDOI
The relationship between the quantum yield of photosynthetic electron transport and quenching of chlorophyll fluorescence
TL;DR: In this article, the quantum yield of non-cyclic electron transport was found to be directly proportional to the product of the photochemical fluorescence quenching (qQ) and the efficiency of excitation capture by open Photosystem II (PS II) reaction centres (Fv/Fm).
CANOCO Reference Manual and CanoDraw for Windows User's Guide: Software for Canonical Community Ordination (version 4.5)
C.J.F. ter Braak,Petr Šmilauer +1 more
TL;DR: Canoco as discussed by the authors is a software package for multivariate data analysis, with an emphasis on dimesional reduction (ordination), regression analysis, and the combination of the two, constrained ordination.

Partialling out the spatial component of ecological variation
TL;DR: In this paper, a method is proposed to partition the variation of species abundance data into independent components: pure spatial, pure environmental, spatial component of environmental influence, and undetermined.
