1. Optimization of chromatographic conditions and comparison of extraction efficiencies of four different methods for determination and quantification of pesticide content in bovine milk by UFLC-MS/MS
This paper describes the optimization of a multiresidue chromatographic analysis for the identification and quantification of 20 pesticides in bovine milk, including three carbamates, a carbamate oxime, six organophosphates, two strobilurins, a pyrethroid, an oxazolidinedione, an aryloxyphenoxypropionate acid/ester, a neonicotinoid, a dicarboximide, and thre

3. 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

4. Degradação do aldicarbe em biorreator anaeróbio horizontal de leito fixo / Aldicarb degradation in a horizontal-flow anaerobic immobilized biomass bioreactor
O objetivo principal deste trabalho foi avaliar o desempenho do biorreator anaeróbio horizontal de leito fixo (RAHLF) na degradação de aldicarbe em condições anaeróbias. Foram avaliados três níveis de oxidação: metanogênico, sulfetogênico e desnitrificante. Inicialmente foi desenvolvido o método de detecção de aldicarbe e metabólitos por meio

5. "Desenvolvimento e aplicações de eletrodos modificados com a enzima acetilcolinesterase para a detecção de pesticidas em matrizes de alimentos" / Development and application of acetylcholinesterase enzyme modified electrodes for pesticides determination in food matrices
This work describes the development, characterization and utilization of a carbon paste biosensor based in the acetylcholinesterase enzyme for carbamates determinations in foodstuff, as well as the study of rate constants for enzyme/substrate reaction in solution. Stability tests were initially performed for both the substrate and the enzyme. In these tests,

6. Avaliação tardia do estado de saude de pessoas intoxicadas agudamente por agrotoxicos inibidores das colinesterases
Acute intoxication by cholinesterase-mJnõiting pesticide causes substantial morbidity and mortality worldwide. In Brazil and other countries, the Jate efIects to human health due to acute intoxication by pesticides continue not well known, which is a challenge to researchers. The current writing aimed at to evaluate the heahh conditions of 33 individuaIs, 2

7. Fatal aldicarb intoxication in dogs and cats: study of post mortem macroscopic alterations and toxicological diagnosis using thin-layer chromatography in samples of stomach content / Intoxicação por aldicarb ("chumbinho") em cães e gatos: estudo das alterações post mortem macroscópicas e diagnóstico toxicológico por meio da cromatografia em camada delgada em amostras de conteúdo estomacal
Pesticides are the main cause of poisoning in human beings and in wild and domestic animals. Preliminary data suggest that the carbamate insecticide aldicarb, illegally sold in São Paulo city as rat poison, has also been used for intentional poisoning of dogs and cats.

8. Variation in human herpesvirus susceptibility to enhancement by the pesticide carbaryl.
The ability of various human herpesviruses to be enhanced by the pretreatment of human embryonic lung cells with the pesticide carbaryl (1-naphthyl-N-methyl-carbamate) differs according to the virus tested. Different strains of varicella-zoster virus produced different patterns of susceptibility to enhancement. Laboratory-adapted strains were less sensitive

9. Pesticides and Myocardial Infarction Incidence and Mortality Among Male Pesticide Applicators in the Agricultural Health Study
Acute organophosphate and carbamate pesticide poisonings result in adverse cardiac outcomes. The cardiac effects of chronic low-level pesticide exposure have not been studied. The authors analyzed self-reported lifetime use of pesticides reported at enrollment (1993–1997) and myocardial infarction mortality through 2006 and self-reported nonfatal myocardia
