标题：Desarrollo de una metodología analítica para la determinación de Cd, Pb y As en frutas y hortalizas como una alternativa a los métodos estándar de análisis
摘要：Food safety encompasses different actions in order to guarantee maximum security. Almost all of the fruits and some vegetables can be consumed raw, but they can contain contaminants that reach the product at any point, from its cultivation, harvest, and even in the processing chain, that takes it to the final consumer. In order to monitor inorganic pollutants, arsenic (As), cadmium (Cd) and lead (Pb) quickly, reliably and in accordance with the principles of Green Chemistry, an analytical method was developed and validated for simultaneous extraction of these elements using a microwave-assisted procedure, in a single step and using diluted acid. The validated method was applied with four products: carrot, lettuce, apple and tomato. The performance parameters of this methodology indicated that it was adequate to monitor the referred foods taking as reference the current regulations and all the samples analyzed met the established criteria. These kind of studies applied to food safety are relevant and in this case, an analytical platform is now available for productive sector and national control agencies.
