Resumen : An investigation has been carried out to establish a rapid method for the determination of copper, chromium, iron and lead in pine needle samples by electrothermal atomisation atomic absorption spectrometry with slurry sampling. In order to determine the accuracy of the proposed method, certified pine needle samples (National Bureau of Standards Standard Reference Material 1575) were analysed according to the proposed method and the results obtained compared with those obtained using a standard wet-ashing procedure. The results obtained by the proposed slurry procedure have sensitivities, reproducibilities and detection limits similar to those observed when solutions of the same samples are analysed.
