The present study is carried out to measure zinc and cadmium in twenty samples of anti-dandruff shampoo products commercially available in the localcosmetic markets in Libya. Detection of zinc and cadmium were done by Flame Atomic Absorption Spectrophotometry (FAAS) method. The results showed that cadmium concentration ranged between 0.017 and 9.37 mg.kg−1 while zinc concentration ranged between 25.9mg kg−1and 8300mg.kg−1. These measurements indicated that cadmium and zinc contents in the investigated samples were higher than WHO limits; suggesting that chronological use of these shampoo products would impose serious health risks to human users. Therefore, quality control and concentration optimism should be implemented to assure the safety of cosmetic products. This also can be achieved by improving the processing and manufacturing practices in the industry.

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.
