Takia Lograda, Zahra Harkati, Katia Adel and Messaoud Ramdani*

Abstract

Levels of six trace metals were assessed in five species (Marrubium vulgare, Hertia cheirifolia, Gladiolus italicus, Triticum turgidum and Juncus maritimus) and their association with the bio-accumulation was investigated. Samples were collected at 2 sites. The species studied, have high contents of ETM, with average metal concentrations; Pb (1,97 ± 5,33); Zn (5,41 ± 5,55); Cu (0,45 ± 0,18); Fe (42, 54 ± 62, 58); Mn (8,81 ± 6,35) and Cd (0,42 ± 0,42). The sampled of plants of the mine Kharzet youcef show very high concentrations of Mn, Zn and Cd, by against, the concentrations of these elements in plant samples of Mehdia site are very low. The concentrations of Fe in species M. vulgare and H. cheirifolia sampled from the site Kharzet Youcef, are very high. The Pb rate is very high in H. cheirifolia, sampled from the mine site (1525 mg / kg), concentrations in the other species, are low; generally below standard. These species studied are recognized plants tolerant to the high levels of Cu, Zn, Mn and Cd, and can be used as bio-accumulator and bio-indicator of pollution by these heavy metals.

Keywords: heavy metals, bioaccumulation, bioindication, plants, Mine, Algeria.
