dc.description.abstractEl mercurio es un elemento toxico ampliamente estudiado y la determinación de sus especies se ha priorizado, sin embargo, en la actualidad no hay disponibles referencias de medición en especies características de la región Latinoamericana y del Amazonas. En este sentido el objetivo de esta investigación fue producir un material de referencia de mercurio total y metilmercurio en bagre rayado. Con este propósito se desarrollaron y validaron métodos de medición que permitieron determinar la homogeneidad, estabilidad del material y la medición de los analitos de interés. Los métodos desarrollados tuvieron un alcance entre 0.25 mg/kg y 20 mg/kg y para todos se obtuvieron variaciones y sesgos aceptables. Finalmente, para resolver esta problemática se obtuvo un material de referencia certificado de especies de mercurio en bagre rayado; el INM-017-1, con un tamaño de lote de 119 unidades, de 15 g de contenido con un valor certificado de HgTotal de 3.94 ± 0.28 mg/kg (k= 1.97) y de MeHg 3.80 ± 0.32 mg/kg (k= 1.97) (Texto tomado de la fuente).spa
dc.description.abstractMercury is a widely studied toxic element and the determination of its species has been prioritized, however, currently there are no measurement references available in species characteristic of the Latin American and Amazon region. In this sense, the objective of this research was to produce a reference material for total mercury and methylmercury in striped catfish. For this purpose, measurement methods were developed and validated that allowed determining the homogeneity, stability of the material and the measurement of the analytes of interest. The developed methods had a range between 0.25 mg/kg and 20 mg/kg and acceptable variations and biases were obtained for all of them. Finally, to solve this problem, certified reference material of mercury species in striped catfish was obtained; the INM-017-1, with a batch size of 119 units, 15 g content with a certified value of HgTotal of 3.93 ± 0.27 mg/kg (k= 1.97) and MeHg 3.79 ± 0.32 mg/kg (k = 1.97).eng
