Abstract

BEDREGAL, Patricia et al. The use of Usnea sp. and Tillandsia capillaris as biomonitors of environmetal pollution in Lima city, Peru. Rev. Soc. Quím. Perú [online]. 2009, vol.75, n.4, pp.479-487. ISSN 1810-634X.

In order to evaluate pollution in the city of Lima, Peru, an environmental monitoring was carried out using two species of biomonitors: Liquen Usnea sp. and Tillandsia capillaries. Both samples were taken from an uncontaminated area to be exposed during three months in different sampling sites of the city. Then samples were collected, prepared and analyzed by instrumental neutron activation analysis, based k₀ method. Results showed important contamination in East and North sites of the city coming from industrial activities and automotive vehicles emissions.

Keywords : biomonitoring; neutron activation analysis; lichen; Tillandsia capillaris.
