1. DETERMINAÇÃO DE MULTIRRESÍDUOS DE AGROTÓXICOS EM MÉIS PRODUZIDOS NA REGIÃO DO TRIÂNGULO MINEIRO POR UHPLC-MS/MS
Excessive use of pesticides can lead to the accumulation of residues in different parts of plants, endangering various species and contaminating foods. Honey can be used as an indicator of agricultural contamination and pre-mature bee mortality by pesticides. However, to quantify pesticide residues in honey, high sensitivity analytical methodologies are requ

2. Impact of Fungicide Residues on Polymerase Chain Reaction and on Yeast Metabolism
ABSTRACT The indiscriminate use of pesticides on grape crops is harmful for consumers´ healthin “in natura” consumption and in the ingestion of wine and grape juice. During winemaking, a rapid and efficient fermentation stage is critical to avoid proliferation of contaminating microorganisms and to guarantee the product´s quality. Polymerase chain reac

3. Evaluation of the performance of a castor-oil based formulation in limiting pesticide residues in strawberry crops
A study was made to evaluate the effect of a castor oil-based detergent on strawberry crops treated with different classes of pesticides, namely deltamethrin, folpet, tebuconazole, abamectin and mancozeb, in a controlled environment. Experimental crops of greenhouse strawberries were cultivated in five different ways with control groups using pesticides and

4. MÉTODOS INDIVIDUAL E MULTIRRESIDUAL PARA DETERMINAÇÃO DE PESTICIDAS EM GRÃOS E DERIVADOS POR GC-PFPD, GC-ITD-MS E LC-MS/MS / SINGLE AND MULTI-RESIDUE METHODS FOR PESTICIDE ANALYSIS IN GRAINS AND DERIVATES BY GC-PFPD, GC-ITD-MS AND LC-MS/MS
Due to the complexity of grains like soybean, corn and rice, and the very low pesticide concentration expected for these samples, it is really necessary to develop efficient and reliable analytical methods to identify and quantify their residues. The possibility to perform the determination of a large number of pesticides in just a single chromatographic ana

5. Monitoramento de agrotóxicos em áreas irrigadas por pivô central na microbacia do Tijunqueiro, município de Morrinhos, Goiás / Pesticides monitoring in irrigated areas by central pivot in the Tijunqueiro Watershed municipality of Morrinhos, Goias
The importance of pesticides to the agricultural system production is indisputable, since they are part of the basics inputs, however, it is essential that they be used properly to be preserved not only the quality of the growing product, but also of their own natural resources, especially soil and water. In this study was conducted the pesticides monitoring

6. VALIDATION AND APPLICATION OF A MODIFIED QuEChERS METHOD AND GC-ECD FOR THE DETERMINATION OF PESTICIDE RESIDUES IN RICE GRAIN AND HUSK / VALIDAÇÃO E APLICAÇÃO DE MÉTODO EMPREGANDO QuEChERS MODIFICADO E GC-ECD PARA DETERMINAÇÃO DE RESÍDUOS DE PESTICIDAS EM GRÃO E CASCA DE ARROZ
The current agriculture is characterized by the use of new technologies and equipment, the increased number of agronomic research and the use of a variety of inputs such as pesticides and fertilizers. All this is directly related to human health risks and environmental contamination caused by the intensive use of pesticides. Among the main food consumed by h

7. DESENVOLVIMENTO DE MÉTODO MULTIRESIDUAL PARA ANÁLISE DE PESTICIDAS EM MEL, UTILIZANDO CROMATOGRAFIA A LÍQUÍDO COM DETECTOR ESPECTROFOTOMÉTRICO COM ARRANJO DE DIODOS / MULTIRESIDUAL METHOD DEVELOPMENT TO ANALYSIS OF PESTICIDES IN HONEY, USING LIQUID CHROMATOGRAPHY WITH SPECTROPHOTOMETRIC DETECTOR WITH ARRANGEMENT OF DIODES
Honey is a product of proven therapeutic and nutritional properties, and which may act as an excellent bioindicator, given the way the bees gather and process the raw material used in its preparation. The monitoring of pesticide residues in honey is important both to control product quality in domestic and international markets, and in assessing the potentia

8. STUDY OF HERBICIDE AMETRYNE DEGRADATION IN HDPE PACKAGING USING THE ADVANCED OXIDATION PROCESS BY IONIZING RADIATION / Processo de oxidação avançada por radiação ionizante na degradação do herbicida Ametrina em embalagens de pead descartadas
This study is part of the project with the objective to evaluate pesticides degradation for decontamination of commercial polymeric packaging of highdensity polyethylene, HDPE, used in agriculture. The herbicide used to this study was the herbicide ametryne (commercial name, Gesapax 500), due to its great use, mainly on field crops and on corn. Ametryne is c

9. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO PARA DETERMINAÇÃO DE ETILENOTIOURÉIA EM URINA EMPREGANDO HPLCUV / DEVELOPMENT AND VALIDATION METHOD FOR THE DETERMINATION OF ETHYLENETHIOUREA IN URINE BY HPLC-UV
In order to supply the world-wilde demand for food, it is essential to use the pesticides to protect the crops against pests and diseases. But the indiscriminate and injudicious use of these compounds have resulted in widespread contamination in food commodities and environment in all fields, increasing, this way, the preoccupation with chemical products use

11. STUDY OF FIELD PESTICIDE STABILITY OF CARBOFURAN AND QUINCLORAC IN THE WATER OF IRRIGATED RICE CROPS USING SPE AND HPLC-DAD / ESTUDO DA ESTABILIDADE A CAMPO DOS PESTICIDAS CARBOFURANO E QUINCLORAQUE EM ÁGUA DE LAVOURA DE ARROZ IRRIGADO EMPREGANDO SPE E HPLC-DAD
The use of pesticides to control pests, diseases and weeds in crops of agricultural interest aims at the increase of production. The degradation of applied compounds or their conversion into other products, does not necessarily mean the loss of biological activity, and many times, this conversion can result in even more toxic and active products. The study o

12. Triple rinse efficiency at received containers in pesticide containers collection units / Eficiencia da triplice lavagem em unidades de recebimento de embalagens de agrotoxicos
Pesticide formulations have been used in agriculture worldwide to protect the crops and soils from the attack of any pest. These formulations must be stored in safe containers proper to each kind of product. After use, the empty containers contaminated with pesticide residues must be disposed correctly and safely by triple rinse, the technical legislation re
