Quantification of pesticide residues is expensive and mostly inaccessible to farmers, health authorities and supervisory entities.This paper describes a simple, economical and simple method for quantifying carbofuran in tubers. The differential pulse voltammetry method for carbofuran was validated for quantification in potato. A Britton-Robinson buffer was used as an electrolyte supporting solution, glassy carbon as working electrode, Ag/AgCl as reference electrode and platinum as counter electrode. The pesticide was extracted from the potato through a solid-liquid partition method and the results obtained by voltammetry were compared with UV-Vis spectroscopy deducing that the voltammetric method generates accurate and reliable results for carbofuran quantification in tubers. The proposed method was successfully applied to the determination of carbofuran in potato samples with satisfactory results. These results indicate the use of carbofuran in the town of Ventaquemada in the department of Boyaca, Colombia. This carbofuran detecting method can be used as a tool to monitor the use of this chemical compound in potato tubers.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"275-284"},"PeriodicalIF":0.2,"publicationDate":"2017-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42800613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, society demands natural products with less chemical additives, so that food producers have found it necessary to try to completely remove the use of chemical antimicrobial products and adopt natural alternatives for the maintenance or extension of the lifetime of their products. The purpose of this study was to evaluate the lifetime of Sinuana oatmeal, a native drink of the Department of Cordoba (Colombia), spiked with cloves (Syzygium aromaticum) and cinnamon (Cinnamomum verum) at three different concentrations (0.073, 0.146 and 0.219 % v/v), packaged in plastic bottles (PET) and 500 mL glass and stored at 4 °C for 15 days.

A split-plot design with random blocks was used, in which the forage species was the main plot and the regrowth age the subplot. The main fatty acids found in the species were palmitic acid (C16:0), linolenic acid (C18:3) and linoleic acid (C18:2). However, the fatty acid concentration differed between herbaceous and shrubby legumes compared to non-leguminous species, and decreased with regrowth age in both groups. The herbaceous legumes evaluated had a higher C18:2/ C18:3 proportion than shrubby legumes, which could in turn result in a higher conjugated linoleic acid (cla) content in milk fat. The legume Cajanus cajan showed the highest (p<0.05) cla (C18:3) and cla precursors content in the three regrowth ages evaluated, suggesting that its use as bovine feed in dual-purpose systems can result in higher c9 t11 cla concentrations in milk fat compared to other species.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"217-232"},"PeriodicalIF":0.2,"publicationDate":"2017-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68410765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extraction was carried out with a Matrix solid-phase Dispersion (mspd) technique. Gas chromatography with micro electron capture detector (μ-ecd) was used for the quantifi-cation of carbofuran residues in the samples, using the external standard method. Results obtained from this method were then compared with the Soxhlet technique used for samples contaminated with the commercial product Furadan® 3SC. Different parameters affecting the mspd extraction process were evaluated, such as the stationary phase, the solvent and elution volume in soil samples trea-ted with Furadan® 3SC to a final concentration of 50 mg/kg-1 of active ingredient (carbofuran). The recovery rate was used as a response variable. The best carbofuran extraction conditions for these matrices were obtained with 0.2 g of macerated sample with 0.8 g of silica gel as adsorbent in a 1:4 sample/adsorbent ratio. Samples were extracted on a cartridge with 5 ml of hexane-acetone at a 8:2 ratio as an elution solvent.

Variability was observed in 39 of the 41 qualitative variables, which indicates a 95.12 % polymorphism rate of the recorded attributes, with a maximum of 90 % and minimum of 50 % similarity among accessions. On the other hand, all 31 recorded quantitative attributes exhibited variability among plant materials in the collection. In addition, 16 plant materials did not produce any inflorescences during the study, which indicates that there are behavioral differences under the same environment which are likely associated to their genetic makeup.

Throughout a review, the total number of service stations in the city urban area was determined. Carrying on interviews to employers that attend public, the sales of fossil fuels (gasoline, diesel and natural gas vehicle-ngv), were determined and based on the total number of stations and emission factors, it was estimated the total emission from each fuel in the city. Some mitigation options, such as coffee, cocoa and teak plantations have been proposed. It was estimated an emission of 368 Gg CO2/year (1 Gg = 10⁹ g) from sales of fuels, equivalent to 718 kg CO2/person/year. These ghgemissions should be mitigated with reduction in the use of fossil fuels or throughout establishment of agricultural and forestry production systems which allows fixating CO2.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"103-112"},"PeriodicalIF":0.2,"publicationDate":"2016-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21930/RCTA.VOL18_NUM1_ART:561","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68410424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
