RESUMO
In this work, an analytical method for the determination of Cd and Pb in natural coconut water samples, industrialized coconut water samples and coconut milk using high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS), after minimum treatment of the sample was developed. The analytical method was applied to 46 samples collected in Salvador, Bahia (Brazil). The ranges of concentrations obtained were: 0.42-18.72⯵gâ¯L-1 Cd and <0.70-36.32⯵gâ¯L-1â¯Pb for natural coconut water samples (nâ¯=â¯14); <0.06-1.49⯵gâ¯L-1â¯Cd and 6.57-29.02⯵gâ¯L-1â¯Pb for industrialized water coconut samples (nâ¯=â¯16); and <0.10-5.93â¯ngâ¯g-1â¯Cd and <0.85-22.41â¯ngâ¯g-1â¯Pb for coconut milk samples (nâ¯=â¯16). For all samples, Cd and Pb concentrations were below the maximum tolerated values recommended by Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, ANVISA).
