Contaminación Cuyo (Argentina : región) Metales Productos comerciales Tomate |

In order to determine normal and contaminating levels of metallic elements in
different commercial tomato products, 47 samples coming from different industries in
Cuyo (Argentina) were selected. The products included were double and triple extracts, smashed tomatoes, ground tomatoes, peeled tomatoes and portuguese sauce. Laboratory samples were carefully conditioned, dried by means of air circulating heaters and mineralized via dry process to obtain hydrochloric extracts with a 1:50 final dilution.
Lead, cadmium, chromium, copper, iron and zinc contents were measured in the extracts using a Perkin-Elmer atomic absorption spectro-photometer.
Statistical analysis of the analytical results included the most important sample
characteristics such as mean value, standard deviation and variance for every tested
element. Results show that lead was present in all the tested samples, in levels ranging from 3,28 mg/kg to 56,29 mg/kg. Chromium was present in 61,7 % of the samples, with levels between 1,66 and 5,53 mg/kg.
Cadmium was found in 78,7 % of the samples, in levels ranging between 0,13 and 0,82 mg/kg. Results for the tomato normal
metallic constituents show a high variation coefficient, standing out the iron content, with minimum values of 47,97 mg/kg and maximum values of 2 576 mg/kg. Extreme
values for copper were 8,38 and 115,44 mg/ kg while for zinc extreme values were 16,66 and 88,63 mg/kg.
Para determinar el tenor de metales como constituyentes normales y contaminantes en productos comerciales de tomate: extractos doble y triple, puré, triturado, pelado y salsa portuguesa, se seleccionaron 47 muestras provenientes de 13 establecimientos industriales de Cuyo (Argentina). Las muestras se secaron en estufa con circulación de aire y se mineralizaron para la preparación de extractos clorhídricos, sobre los cuales se cuantificaron plomo, cadmio, cromo, hierro, cobre y zinc, utilizando un espectro-fotómetro de absorción atómica Perkin-Elmer. Con los datos obtenidos se calcularon las características muestrales: media, desviación típica y varianza, para cada elemento, y se determinaron los intervalos de confianza para la media para establecer los valores normales para = 0.05. Los resultados, expresados sobre sustancia seca, indican: • la totalidad de las muestras presentan plomo entre 3,28 y 56,29 mg/kg; • el 61,7 % tiene cromo entre 1,66 y 5,53 mg/kg; • en el 78,7 % de las muestras se detectó de 0,13 a 8,82 mg/kg de cadmio; • los metales constituyentes normales presentan elevado coeficiente de variación, destacándose el hierro de 47,97 a 2 576 mg/kg; • para el cobre, los valores fueron 8,38 y 115,44 mg/kg; • y para el zinc, 16,66 y 88,63 mg/kg. |
