Abstract:

The present work aims to analyze heavy metals in the cones, bark and needles of Aleppo pine in 05 stations in the area of Ain El Kebira in order to evaluate pollution level and impact on reforestation. Analysis of heavy metals showed that the concentration of lead rose to 1.61 mg/l at the station of the BCR which is above the accepted international standards of 1mg / l. Fe concentrations are at the upper limit of the WHO standards of 1.5 mg / l at the station on the edge of the forest ranging from 1.03 to 1.65mg/l against the cement between 1.36 and 2.21 mg / l and the BCR between 1.31 and 2.19 mg / l are the most polluted. It is noted that with the exception of the BCR is to say that the industrial zone where the values found on analysis of copper are too high between 1.11 and 2.59 mg/l and far exceed the required standards set 1 mg / l. The levels of zinc at the station of the BCR and are highest between 3.05 and 6.47 mg / l where the required standards are 5 mg / l. We can infer from our results that urgent care should be initiated to preserve the national park above the Babors bordering our study area and is ranked world reserve.
