摘要: The capability of pine needles to be used as bioindicators trace metals in the environment is discussed. Samples were collected around Instituto de Pesquisas Energeticas e Nucleares, largest nuclear research center South America and chosen sampling target area. Results obtained for elemental content Th U samples nearby an uranium facility were, respectively, 0.072 0.042 mg kg(-1), while results La, Ce Sm a sample vicinity extraction laboratory 0.22, 0.88 0.39 kg(-1). All these values are higher than ones with reference (La 0.12; 0.19, 0.020 0.012 kg(-1)), located far from Internal standardization was compensate non-spectral interference different elements present solution matrix. chemical bismuth (Bi) indium (In) internal standards. In order control accuracy measurement process, certified (NBS SRM 1575) also analyzed. show investigated method determination relevant environment.
