Physiological response of freshwater microalga (Chlorella vulgaris) to triazine and phenylurea herbicides
(2002-09)
[Abstract]The effects of two herbicides used wide-spread, isoproturon (phenylurea) and terbutryn (triazine), on growth, dry weight, elemental composition, photosynthetic pigments and protein content, and cell volume assayed ...
Atrazine-Induced Chlorosis in Synechococcus elongatus Cells
(Springer, 2004)
The effects of a widely used herbicide, atrazine, on the freshwater cyanobacterium Synechococcus elongatus were studied. The cyanobacteria were exposed to varying concentrations of atrazine (0.025, 0.05, 0.1, 0.25, and ...
Alteration of photosynthesis related parameters of Chlamydomonas moewusii stressed by paraquat
(Research Trends, 2008)
Paraquat toxic action on the freshwater microalga Chlamydomonas moewusii was determined by several physiological parameters. ATP content seems to be the most sensitive parameter analyzed; it was reduced by the lowest ...
Screening acute cytotoxicity biomarkers using a microalga as test organism
(Elsevier, 2012-12)
The present study checked the suitability of the integration of flow cytometry (FCM) as technique and a freshwater microalga (Chlamydomonas moewusii) as cell system model for ecotoxicological studies, looking for sensitive ...
Atrazine induced changes in elemental and biochemical composition and nitrate reductase activity in Chlamydomonas reinhardtii
(Taylor & Francis, 2016)
Herbicides play an important role in agricultural practices but the introduction of these compounds into the aquatic environment can have severe consequences for non-target organisms such as microalgae. The ubiquitous green ...
Comparison of the sensitivity of different toxicity test endpoints in a microalga exposed to the herbicide paraquat
(2009-02)
[Abstract]The use of herbicides constitutes the principal method of weed control but the introduction of these compounds into the aquatic environment can provoke severe consequences for non-target organisms such as microalgae. ...
Flow cytometric analysis of the encystment process induced by paraquat exposure in Haematococcus pluvialis (Chlorophyceae)
(Taylor & Francis, 2011)
The freshwater microalga Haematococcus pluvialis exhibits a unique morphological response to environmental stress, accumulating carotenoid pigment during encystment. The complexity of characterizing the different cell ...
Flow cytometric assay to assess short-term effects of personal care products on the marine microalga Tetraselmis suecica
(Elsevier, 2017)
[Abstract] Large quantities of personal care products (PCPs) are used daily and many of their chemical ingredients are subsequently released into marine environments. Cultures of the marine microalga Tetraselmis suecica ...
Flow cytometric analysis to evaluate physiological alterations in herbicide-exposed Chlamydomonas moewusii cells
(Springer, 2012-03)
Investigation of herbicide toxicology in non-target aquatic primary producers such as microalgae is of great importance from an ecological point of view. In order to study the toxicity of the widely used herbicide paraquat ...
The herbicide paraquat induces alterations in the elemental and biochemical composition of non-target microalgal species
(2009-09)
[Abstract]Huge quantities of pesticides are dispersed in the environment, affecting non-target organisms. Since paraquat affects the photosynthetic process, the biochemical composition of affected species should be altered. ...
