Ecotoxicity Evaluation of the Biodegradable Polymers PLA, PBAT and its Blends Using Allium cepa as Test Organism
(2018-03-01)
Biodegradable polymers are considered a feasible option to minimize the environment impacts of high disposal of solid waste. Nevertheless, environmental safety of these materials is a few explored issue. In this context, ...
Atrazine and Methyl viologen effects on Chlorophyll-a fluorescence revisited. Implications in Photosystems Emission and Ecotoxicity Assessment
(Wiley, 2014-01)
In this work, we use the effect of herbicides that affect the photosynthetic chain at dened sites in the photosynthetic reaction steps to derive information about the uorescence emission of photosystems. The interpretation ...
N-Acetylated Gemini Surfactants: Synthesis, Surface-Active Properties, Antifungal Activity, and Ecotoxicity Bioassays
(Scientific Research Publishing, 2015-05)
A series of N-acetylated cationic gemini surfactants (3a-e) having dimeric structures derived from tertiary amines were synthesized. Their antifungal potency and surface properties were determined. It also studied the acute ...
PLA and Organoclays Nanocomposites: Degradation Process and Evaluation of ecotoxicity Using Allium cepa as Test Organism
(Springer/plenum PublishersNew YorkEUA, 2013)
Ecotoxicity of TiO2 to Daphnia similis under irradiation
(Elsevier Science BvAmsterdamHolanda, 2012)
PLA and Organoclays Nanocomposites: Degradation Process and Evaluation of ecotoxicity Using Allium cepa as Test Organism
(2013-07-17)
In this study, nanocomposites of PLA and organoclays Cloisite 20A and Cloisite 30B were prepared by the melt intercalation method and the obtained samples were characterized by transmission electron microscopy (TEM). Since ...
Disposal Of Dredged Sediments In Tropical Soils: Metal Ecological Risk Assessment Based On Bioassays With Aquatic And Edaphic Organisms
(ASSOC BRASILEIRA ENGENHARIA SANITARIA AMBIENTALRIO DE JANEIRO, 2015)
Age-related differential sensitivity to cadmium in Hyalella curvispina (Amphipoda) and implications in ecotoxicity studies
(Elsevier Inc, 2010-02)
The standardization of toxicity tests requires the selection of the most suitable test species and their developmental stages, as well as the selection of the appropriate assay matrix and the evaluation of the sensitivity ...
Teflubenzuron as a tool for control of trichodinids in freshwater fish: Acute toxicity and in vivo efficacy
(Elsevier B.V., 2015-07-01)
In this study we describe the anti-Trichodina effects of teflubenzuron (TFB) for Oreochromis niloticus and for Piaractus mesopotamicus. We also evaluated the acute toxicity, for both species, by using TFB in the concentrations ...
