Brazil is the world’s third largest common bean (Phaseolus vulgaris L.) producer, and 60% of its population consumes this legume. Although organic farming a sustainable alternative to nonorganic agriculture, effect on chemical composition still controversial. Therefore, aim study was investigate differences in nutritional phenolic compounds profiles between organically nonorganically produced Brazilian black beans. Samples were obtained from same harvest periods near geographical locations...
Os hexaclorociclohexanos (HCHs) são atualmente considerados carcinógenos humanos. No Brasil, uma severa contaminação de solo causada por HCHs é observada na Cidade dos Meninos, Duque Caxias, Rio Janeiro, onde antiga fábrica desses compostos foi abandonada há quarenta anos, ameaçando seus 1.700 habitantes. Para remediar a área pesadamente contaminada (área foco), um tratamento com óxido cálcio realizado. Análises coletadas superficialmente tratada, anos após o tratamento, mostraram ainda...
Neste trabalho, otimizou-se um método analítico para a determinação de resíduos os agrotóxicos-foco: Azoxistrobina, Boscalida, Carbendazim, Clorantraniliprole, Clotianidina, Diafentiuron, Difenoconazol, Dimetomorfe, Espinetoram, Espinosade A, D, Fenuron, Imidacloprido, Indoxacarbe, Metalaxil M, Metoxifenozida, Tiametoxan em solo derivado do plantio tomate, com o objetivo comparar níveis contaminação desses compostos amostras solo. Foi utilizado extração QuEChERS modificado e Cromatografia...
The proficiency testing for determination of pesticides residues in mango pulp was the third work partnership established by INMETRO and INCQS/Fiocruz. Three samples were sent to each participant laboratory, two being spiked with one exempt pesticides. added were: deltamethrin, ethion, fenitrothion, malathion, permethrin. evaluation results homogeneity stability tests, as well assigned value made agreement ISO GUIDE 35 13528, assuming considered homogeneous stable studied period. values...
WITH FLAME PHOTOMETRIC DETECTOR.Samples of whole fluid pasteurized, UHT and powdered milk were analyzed for the presence organophosphorus pesticide residues (OPR) using QuEChERS method with detection by GC-FPD confirmation UPLC-MS/MS.A total 23% samples 27% contained at least one residue.The OPR found in showed these can reach remain even after pasteurization, sterilization drying processes.Some domestic sanitary also present samples.These have no LMR Brazilian food legislation are therefore...
Bivalve molluscs (BM) are filter animals and bioaccumulators of substances from the environment. This characteristic allows a great absorption nutrients that makes them source protein-rich foods. On other hand, if there toxic contaminants in environment, their by may occur. happens with pesticides coming agricultural livestock production systems can migrate to areas BM crops. Considering high nutritional value bivalve positive impact on human diet, these products must be carefully evaluated...
RESUMO Alimentação adequada durante os primeiros anos de vida é fundamental para a saúde e tem repercussões em todos ciclos da do indivíduo. Diversos trabalhos científicos associam efeitos nocivos à com exposição aos agrotóxicos. Foram avaliados 312 agrotóxicos alimentos comumente presentes na dieta infantil, selecionados partir cardápio programa alimentação escolar educação infantil município Rio Janeiro. A seleção dos baseou-se frequência consumo conforme cardápios semanais rede municipal...
O presente estudo teve por finalidade avaliar a situação atual do consumo de alimentos à base soja disponíveis no mercado em relação presença resíduos agrotóxicos. A metodologia foi validada para efetuar determinação 122 pesticida na matriz e 124 substâncias extrato solúvel soja. As curvas analíticas estudadas nas duas matrizes apresentaram linearidade faixa trabalho analisada (0,002 0,200 μg.mL-1). exatidão precisão dois níveis fortificação valores 70 % 119 recuperação CV (%) 1 18. Limite...
The possibility of occurring the soy and derivatives samples contamination with pesticide residues has become significant due to increased use these products in human nourishment. In this context, present study aimed at validating acetate QuEChERS multiresidue methodology for analyzing 144 soybean soluble extract using high-performance liquid chromatography coupled tandem mass spectrometry. parameters evaluated were: selectivity (matrix effect two sample types), linearity (working range,...
Esta pesquisa comparou os niveis de contaminacao por agrotoxicos nos solos provenientes tres sistemas plantios do tomate: convencional, orgânico e sustentavel. O trabalho foi realizado em uma parceria entre o Programa Engenharia Ambiental da UFRJ (PEA); Instituto Nacional Qualidade Saude (INCQS/FIOCRUZ) Pesquisa Solo (INPS/EMBRAPA). otimizou um metodo para determinacao quantitativa 241 plantacao tomate sistemas. Foi utilizado extracao QuEChERS Cromatografia Liquida Ultra Resolucao acoplada...
