Glifosato: propriedades, toxicidade, usos e legislação
Ozelito Possidônio de Amarante Junior,Teresa Cristina Rodrigues dos Santos,Natilene Mesquita Brito,Maria Lúcia Ribeiro +3 more
TL;DR: In this article, a compact revision on the herbicide glyphosate physic-chemistry characteristic mains, including toxicity and valid Brazilian legislation for its use, is presented, along with a detailed discussion of its application in agriculture.
Journal ArticleDOI
Validação de métodos analíticos: estratégia e discussão
Natilene Mesquita Brito,Ozelito Possidônio de Amarante Junior,Luciana Polese,Maria Lúcia Ribeiro +3 more
TL;DR: In this paper, the authors present the definitions of the parameters (selectivity, limits of detection and quantification, accuracy, precision,linearity, analytical graphic, sensitivity and ruggedness) considered on analytical methods validation procedures.
Journal ArticleDOI
Determination of pesticide residues in coconut water by liquid-liquid extraction and gas chromatography with electron-capture plus thermionic specific detection and solid-phase extraction and high-performance liquid chromatography with ultraviolet detection.
Natilene Mesquita Brito,Sandro Navickiene,Luciana Polese,E. F. G. Jardim,R. B. Abakerli,Maria Lúcia Ribeiro +5 more
TL;DR: Two simple methods were developed to determine 11 pesticides in coconut water, a natural isotonic drink rich in salts, sugars and vitamins consumed by the people and athletes, and no detectable amounts of the pesticides were found in any samples under the conditions described.
Journal ArticleDOI
Detection of carbamate pesticides in vegetable samples using cholinesterase-based biosensors
TL;DR: Biosensors for determination of carbamates in vegetables based on five different cholinesterase as biorecognition elements and a screen-printed electrode system as an amperometric transducer were developed Measurements were simply performed by dropping solutions (either sample or substrate) directly on the biosensor as discussed by the authors.
Journal ArticleDOI
Pesticide Levels in Ground and Surface Waters of Primavera do Leste Region, Mato Grosso, Brazil
Eliana Freire Gaspar de Carvalho Dores,Leandro Carbo,Maria Lúcia Ribeiro,Ermelinda M. De-Lamonica-Freire +3 more
TL;DR: It is deducted that the contamination of water resources is predominantly caused by non-point pollution of pesticides used in intensive cash-crop cultures of the Cerrado area, and a continuous monitoring of pesticide concentrations in water resources of this tropical region is necessary to detect the longer term contamination trends and developing health risks.
