Evaluación del contenido de plomo y cadmio en peces del río Lebrija en el corregimiento provincia, municipio de Sabana de Torres empleando espectrofotometria de absorción atómica

Abstract

The content of cadmium (Cd) and lead (Pb) in 30 samples collected bocachico during rainy season and dry season is determined. The determination was performed using the technique of atomic absorption spectrophotometry after validation of the methodology used, all concentrations are expressed in wet weight. The evaluation was conducted in order to verify that products obtained on the Lebrija River in points Conchal, Salamaga and Vanegas upstream of judges province, municipality of Sabana de Torres, meet the criteria laid down in national regulations NTC 1322: 2009 (0.1 mg Cd / kg and 0.4 mg Pb / kg) and international standards in the consolidated Regulation (EC) No. 1881/2006 of the European Union (0.1 mg Cd / kg and 0.3 mg Pb / Kg) and the Codex Alimentarius 2002 (0.05 mg Cd / kg and 0.1 mg Pb / kg) and discard mortality of fish contamination of heavy metals such as cadmium and lead. The concentrations found in muscle and skin samples bocachico, they were below the limits of quantification (0.125 mg Pb / kg and 0.035 mg Cd / kg) obtained during validation. The results showed that the samples analyzed are fit for human consumption according to national and international environmental regulations.
