Comparative sensitivity of Scenedesmus acutus and Chlorella pyrenoidosa as sentinel organisms for aquatic ecotoxicity assessment: Studies on a highly polluted urban river
(John Wiley & Sons Inc, 2000-01)
The effects of spatial and temporal differences on the water quality of the urban contaminated Reconquista River (Argentina) were evaluated by means of bioassays based on the growth of two algal populations (Chlorella ...
An in situ test to explore the responses of Scenedesmus acutus and Lepocinclis acus as indicators of the changes in water quality in lowland streams
(Academic Press Inc Elsevier Science, 2012-11)
This bioassay was designed with the aim of exploring the responses of two wild planktonic microalgae exposed in situ (72. h) as indicators of the changes in water quality. Monocultures of both strains within dialysis ...
Differential sensitivity of developmental stages of the South American toad to a fungicide based on fludioxonil and metalaxyl-M
(Springer Heidelberg, 2018-08)
Agricultural fungicide application in Argentina has increased twice since 2008, with Maxim® XL (2.5% fludioxonil +1% metalaxyl-M) as one of the most used fungicide formulation. The toxicity of this pesticide on Rhinella ...
Toxicity and genotoxicity assessment in sediments from the Matanza-Riachuelo river basin (Argentina) under the influence of heavy metals and organic contaminants
(Academic Press Inc Elsevier Science, 2017-01)
The aim of this study was to investigate the parameters of chemical extraction associated with the detection of toxicity and genotoxicity in sediment sample extracts. Quantitative analysis of metals and polycyclic aromatic ...
Synthesis and evaluation of phytotoxicity of disugran analogues
(Bentham Science Publishers, 2009-12)
We report the synthesis and phototoxicity of the compounds involved in the SRN1-Stille reactions such as methyl 2, 5-diphenylbenzoate (6), methyl 5-chloro-2-phenylbenzoate (7) and methyl 2-methoxy-3, 6-diphenylbenzoate (8) ...
Biochemical response of amphipods (Gammarid: Paramorea) in a sediment laboratory exposure from Ushuaia Bay, Beagle Channel
(Elsevier Inc, 2011-01)
A coastal system (Ushuaia Bay, Argentina) impacted by anthropogenic activities was studied by the response of local amphipods (Parmorea sp., Gammaridae) to the exposure of coastal sediments in a laboratory assay. Four ...
Toxicity of three comercial tannins to the nuisance invasive species Limnoperna fortunei (Dunker, 1857): implications for control
(Parlar Scientific Publications, 2011-06)
Adding biocides to water is one strategy to control macrofouling organisms. A natural biocide that helps to prevent/control macrofouling of Limnoperna fortunei (Dunker, 1857) on human installations is one way to minimize ...
Orugas militares en algodón
(Asociación para la Promoción de la Producción Algodonera, Argentina, 2020)
Las “orugas militares”, pertenecen a la familia Noctuidae, la especie más representativa de este complejo
es el “gusano cogollero” considerado una de las plagas principales de maíz, como también en otros cultivos. Las ...
