“…Examples of the trees species that have been successfully used to monitor the levels of aerial heavy metals were Fraxinus pennsylvanica [4], Pinus massoniana L. [5], Azadirachta indica [6], Casuarina equisetifolia and Delonix regia [7]. Since the most important criteria in the selection of a bioindicator is common occurrence [8], the species of the selected tree is specific to the study area in terms of the abundance of the tree species present. Moreover, most of the studies concerned with the use of trees as a bioindicator have been conducted in Europe and a number of other developed countries.…”

Abstract-Use of vegetation as a bioindicator of atmospheric heavy metal accumulation has received more attention worldwide due to the fact that this method has been found to be effective, cheap and simple to use. This study aims to find out the levels of heavy metals found in tree bark layers and to test the factors (exposed sides of tree to traffic and size of tree trunk) that affect atmospheric heavy metal accumulation in the bark of Cassia fistula, which is a common tree commonly found along the road sides and planted for shading and decoration. In order to provide the necessary information with regard to using a native tree species as a bioindicator, heavy metals emitted from road traffic including Cr, Cu, Fe, Ni, Pb and Zn were investigated. The results showed that only Cu, Fe and Zn were detected. Their concentrations were highest in the cork layer, decreased in the second (chlorenchyma), third (phloem) layers and increased in the innermost layer (vascular cambium). Heavy metals found on the outer most layer of bark definitely came from atmospheric pollution due to direct exposure to the environment. However, the concentrations in the vascular cambium were higher than in the chlorenchyma and phloem. This is probably due to some diffusion that took place in the xylem, which is connected to the cambium layer. Concerning the factors affecting the heavy metal accumulation in the tree bark, the size of Cassia fistula tree trunks (5 -30 cm) was not significantly correlated (p > 0.05) with the heavy metal concentrations found in the bark. This was also true of the sides of the exposure of the tree in relation to the traffic source. This means that the bark sampling can be done easily without any limitations with regard to the size of tree trunk and direction of exposure.Index Terms-Tree bark, heavy metal, bioindicator, Cassia fistula, atmospheric pollution.

“…Biomonitoring and chemical analytical methods have been increasingly developed to assess the atmospheric pollution of trace metals. The moss technique developed by Ruhling and Tyler (1971) has been widely used to estimate regional atmospheric trace metal deposition (Berg and Steinnes, 1997;Wolterbeek, 2002). The advantage of this technique is that their metal uptake is only derived from atmospheric deposition and no expensive equipment is needed.…”

“…As plantas mais comuns usadas no biomonitoramento são os musgos devido à alta capacidade de troca iônica e a acumulação de poluentes não só na superfície, mas também em nível celular. Os musgos são bastante dependentes da qualidade do ar e vulneráveis às poluições atmosféricas, servindo, desse modo, como um bioindicador ideal, e o seu uso tem se tornado muito comum por causarem menos problemas técnicos e analíticos comparados aos liquens e outros tipos de plantas [5,6].…”

Resumo: O presente trabalho refere-se ao biomonitoramento ativo moss bag da qualidade do ar de Ipatinga -MG, utilizando Sphagnum capillifolium, determinando-se os metais Al, Ca, Cd, Cr, Co, Cu, Fe, In, Li, Mg, Mn, Ni, Pb, Sn, Sr, Tl e Zn adsorvidos no material vegetal através da técnica analítica de Espectrometria de Emissão Óptica com Plasma Acoplado Indutivamente (ICP-OES). Foi utilizada a ferramenta computacional Redes de Kohonen ou Mapas Auto Organizáveis para verificar as similaridades e diferenças de amostras e variáveis. Através dos mapas obtidos foi possível visualizar correlações positivas com as observações experimentais. Tanto no período seco quanto no chuvoso, verificou-se que a maioria dos metais determinados nas amostras vegetais foi identificada nos bairros da região sul desta pesquisa, região predominante da direção dos ventos e próxima à siderúrgica local. No período seco foram determinadas as maiores concentrações dos metais.
