Resumo: In the conventional and hydroponic cultivation of lettuce, agricultural defensives and fertilizers are used, which presents concentrations of toxic elements in its composition and may alter the aliment’s quality. Thus, the present study aims to evaluate the content of the heavy metals Cd, Cr, Cu and Pb in soil, nutritive solution and lettuce leaves in the region of Toledo – PR. Samples of lettuce and its substrates were collected from five hydroponic and five conventional proprieties, which were submitted to nitroperchloric digestion for the determination of metal contents through spectrophotometry of atomic adsorption AAS/6300. The experimental delimitation was entirely randomized, with ten treatments and three repetitions, and the results were submitted to variance analysis and to Turkey’s test at 5% significance level; also, the Pearson’s correlation (r) was performed between the variables substrate and lettuce leaves. It was observed that the lettuce studied, in general, presented higher contents of Cd and Cr in the hydroponic cultivation - in which 5 of the hydroponic proprieties, 4 of them presented significantly superior than the conventional ones - according to the Turkey’s test; for the element Cu, significant difference also occurred between the farming methods, however there was significant variance in the cultivation of each property; and for Pb, it was observed that the majority of the samples collected presented higher concentrations than the tolerable limits established by ANVISA - whereas the conventional method presented itself statistically similar between each property, for the hydroponic method, two properties presented themselves significantly superior to the others, and statistically different between each other. When the metal concentrations in the lettuce leaves was compared with the substrate, in general, for both conventional and hydroponic methods the contents in the lettuce didn’t show correlation to the contents in the substrate, which indicate that the contamination may be occurring through the use of agrochemicals and agricultural inputs, used for the control of plagues and diseases, aside from inappropriate management. Thus, it is possible to conclude that the variation in metal concentrations in the same cultivation method is due to the fact that the use of different agrochemicals and fertilizes is allowed, which contain different compositions. Furthermore, the pulverization date previous to sampling of the lettuce may have caused some variations to the composition of the vegetable, as well as inappropriate handling of the aliment.

Dessa forma, o presente trabalho objetivou avaliar os teores dos metais pesados Cd, Cr, Cu e Pb em solo, solução nutritiva e folhas de alfaces na região de Toledo – PR. Foram coletadas amostras de alfaces e de seus substratos em cinco propriedades hidropônicas e cinco convencionais, cujas amostras foram submetidas à digestão nítrico-perclórica para determinação dos teores de metais por meio de espectrofotômetro de absorção atômica AAS/6300. O delineamento experimental foi inteiramente casualizado, com dez tratamentos e três repetições e os resultados foram submetidos à análise de variância e ao teste Tukey ao nível de 5% de significância; ainda foi realizada a correlação de Pearson (r) entre as variáveis substrato e folhas de alface. Observou-se que as alfaces estudadas em geral apresentaram maiores concentrações de Cd e Cr no cultivo hidropônico, sendo que dos 5 cultivos hidropônicos, 4 deles mostraram-se significativamente superiores ao cultivo convencional pelo teste de Tukey; para o elemento Cu, também ocorreu diferença significativa entre os cultivos, no entanto houve uma grande variação entre as culturas e para o Pb, observou-se que a maioria das amostras coletadas apresentavam concentrações superiores ao limite tolerável estabelecido pela ANVISA, sendo que o cultivo convencional mostrou-se estatisticamente semelhante entre si; quanto aos cultivos hidropônicos, dois cultivos mostraram-se significativamente superiores aos demais, e estatisticamente diferentes entre si. Quando comparadas as concentrações de metais nas folhas de alface com o substrato, de forma geral, tanto para o cultivo convencional, quanto para o cultivo hidropônico os teores na alface não apresentaram correlação com os teores no substrato, o que indica que a contaminação pode estar ocorrendo através do uso de agrotóxicos e insumos utilizados para o controle de pragas e doenças, além do manejo inadequado. Assim, pode-se dizer que a variação nas concentrações de metais na mesma cultura deve-se ao fato de ser permitido o uso de diferentes agrotóxicos e fertilizantes, os quais possuem composições distintas. Além disso, a data de pulverização previamente à coleta das alfaces pode ter ocasionado algumas variações na composição da hortaliça, bem como o manejo inadequado do alimento.Submitted by Marilene Donadel (marilene.donadel@unioeste.br) on 2018-06-06T23:01:45Z No. of bitstreams: 1 Camila_Santos_2018.pdf: 1490357 bytes, checksum: 51ef5bf6ae6ed45d1e8d3337275493fb (MD5)Made available in DSpace on 2018-06-06T23:01:45Z (GMT).
