SYNTHESIS, THERMAL STUDIES AND CONVERSION DEGREE OF DIMETHACRYLATE POLYMERS USING NEW NON-TOXIC COINITIATORS
(Soc Brasileira Quimica, 2017-05-01)
The aim of this paper is to replace toxic coinitiators (tertiary amines) by non-toxic compounds such as glycerol and inositol (polyalcohol) in dimethacrylate resins. For this purpose, mid infrared spectroscopy (MIR) was ...
Toxicity of three emerging contaminants to non-target marine organisms
(2019-06-01)
Coastal areas are continually impacted by anthropic activities because they shelter large urban conglomerates. Urban effluents directly or indirectly end up reaching the marine environment, releasing a large number of ...
Acute toxicity and environmental risk of teflubenzuron to Daphnia magna, Poecilia reticulata and Lemna minor in the absence and presence of sediment
(2013-07-01)
This study aimed to estimate the acute toxicity of teflubenzuron (1-(3,5-dichloro-2,4-difluorophenyl)-3-(2,6-difluorobenzoyl)urea) (TFB) for Daphnia magna, Lemna minor and Poecilia reticulata, in the absence and presence ...

(2013-07-01)
This study aimed to estimate the acute toxicity of teflubenzuron (1-(3,5-dichloro-2,4-difluorophenyl)-3-(2,6-difluorobenzoyl)urea) (TFB) for Daphnia magna, Lemna minor and Poecilia reticulata, in the absence and presence ...
Toxicity Persistence of Chlorpyrifos in Runoff from Experimental Soybean Plots to the Non-target Amphipod Hyalella curvispina: Effect of Crop Management
(Springer, 2015-07-04)
Toxicity persistence to the non-target amphipod Hyalella curvispina in runoff events following chlorpyrifos applications to soy experimental plots was compared in conventional and no-till management. Two application scenarios ...
Pollen morphology of four species of Jatropha (Euphorbiaceae), including toxic varieties, in Northwestern Mexico
(Universidad de Costa Rica, 2017)
Integrating toxicity testing in the wastewater management of chemical storage terminals - A proposal based on a ten-year study
(ELSEVIER SCIENCE BV, 2011)
Wastewater control at storage terminals of liquid chemical products in bulk is very difficult because of the variety of products handled in the facilities generating effluents of variable composition. The main objective ...
Different ecophysiological and structural strategies of toxic and non-toxic Microcystis aeruginosa (cyanobacteria) strains assessed under culture conditions
(2019-08-01)
Microcystis aeruginosa causes severe problems in freshwater environments worldwide due to its capacity to form blooms and produce toxins. Natural populations contain a mixture of strains that vary in morphology, genotype ...
