Abstract Lead was determined in the presence of whole multiples of the P/Ca ratio found in Portuguese canned fish by flame atomic absorption spectrophotometry with and without using an ashing aid. Under our experimental conditions, use of the ashing aid eliminates P and Ca interference. Results with real samples, spiked with 1, 2,3, and 4 ppm lead, are presented and statistically treated.

Lontra Longicaudis

The determination of metallic elements by flame atomic absorption spectrophotometry reaffirms the success of the technique for ecological and toxicological studies of environmental contamination. In order to contribute to the scientific research on anthropogenic contamination, the study of Lead in stools of Lontra longicaudis (Olfers, 1818) in the Guaraguaçu River Basin aims to understand the anthropogenic environmental contamination of the local ecosystem, located in one of the largest port areas in Brazil. Six samples were collected along the Guaraguaçu River. To determine the Lead concentration by the flame atomic absorption spectrophotometry method, samples were extracted with HNO3. Concentration values of approximately 1 mg L-1 were detected. There is a need to deepen the development of possible actions to control, monitor and inspection this element in the environment and in its main anthropogenic sources of contamination.

Abstract A method is described for the determination of cobalt in foods. After wet digestion, iron in the sample is removed by liquid-liquid extraction, and cobalt is isolated and extracted. Final determination is done by flame atomic absorption spectrophotometry. Analysis of NBS reference materials by this procedure gives results in close agreement with certified values. The limit of quantitation is 4.3 ng/mL. Recovery studies and analysis of standard materials show that this method is reliable.
