Responses of Typha latifolia subjected to metal stress
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 6
Abstract
In order to preserve the quality of the waste water, we use the macrophyte plants, which go in the direction of the phyto-purification of an aquatic ecosystem. These purifying plants cleanse the water and transform the organic residues into nutritional elements from which they feed. They have a great ability to fix heavy metals. In our job, we orientated our study on the impact of metallic dusts rejected by the steel complex “Arcellor-Mittal” El Hadjar Annaba, on a macrophyte Typha latifolia. The sites of samples (S1, S2, S3, and S4) are located in the neighborhood of the steel complex, and the least polluted site (St) is located far from the sources of pollution. We studied several parameters: of growth (medium number of roots), biochemical (content in protein at root level) and enzymatique (proportion of root catalase activity). We were also studying, the composition of metallic dusts rejected by thehigh stoves of complex Arcellor Mittal. Acquired results show an increase of parameters studied in the four sites of sample (S1, S2, S3, S4), compared with the site least polluted (St). Increase varies between significant (p ≤ 0.05), and very highly significant (p ≤ 0.001). These results explain the capacity of Typha latifolia to fit to the oxydatif stress generated by metallic dusts, Typha latifolia proves to be a very good bioaccumulatrice of heavy metals; we recorded a stimulation in growth, in content in proline and in activity catalase.
