Potential of native plant species from the Industrial Complex of Camaçari (Ba, Brazil) as accumulators of chemical elements contained in air pollution
Resumo
The present study aimed to assess the potential of plant species Anacardium occidentale L., Miconia albicans (Sw.) Triana and Byrsonima sericea DC. as bioaccumulators of aluminum (Al), arsenic (As), copper (Cu), nickel (Ni), zinc (Zn) and sulphur (S), coming from industrial emission from the Industrial Complex of Camaçari (ICC). Element concentrations were measured in the leaves of three adult individuals per species. The data showed that M. albicans is an accumulator species of Al, Cu and S. Moreover, this specie showed visible damage symptoms on the leaves such as chloroses and necroses, which may be attributed to air pollution. On the other hand, the accumulation of the elements was lower in the leaves of A. occidentale and B. sericea. In general, Zn concentrations were similar in all species. As and Ni concentrations in the species were below detection limit. The results indicate that M. albicans may potentially be employed in biomonitoring studies in this region.
