Chibuike, S. Soils polluted with heavy metals have become common across the globe due to increase in geologic and anthropogenic activities. Plants growing on these soils show a reduction in growth, performance, and yield. Bioremediation is an effective method of treating heavy metal polluted soils. Microorganisms and plants employ different mechanisms for the bioremediation of polluted soils.

Alzinc is a ursine situated in the Ghazaouet town western part of the republic of Algeria. The purpose of this study was to determine the degree of contamination which soil and plants are burdened with some heavy metals: Pb, Zn, Ni, Cu, Cd, Mn, Cr, Fe and As, then the accumulation of heavy metals in the soil and plant adjacent of area the alzinc ursine was detected and the interdependence of pollution among all three regions of the environment determined. This paper analyzes the heavy metal contents within a 2-years period in the soil and plants at the beginning of the vegetation period. Measurements of heavy metal contents were performed at three locations in soil and vegetative parts of three-plant types plant alimentary period during summer. The plant samples from the immediate environment of the dumpsite were highly contaminated with Zn, Cd and Mn.

Article Info.

The environment and its compartments have been severely polluted by heavy metals. This has compromised the ability of the environment to foster life and render its intrinsic values. Heavy metals are known to be naturally occurring compounds, but anthropogenic activities introduce them in large quantities in different environmental compartments. This occurs due to bioaccumulation in the food chains as a result of the nondegradable state of the heavy metals. Remediation of heavy metals requires special attention to protect soil quality, air quality, water quality, human health, animal health, and all spheres as a collection.

Raymond A. Wuana, Felix E. Scattered literature is harnessed to critically review the possible sources, chemistry, potential biohazards and best available remedial strategies for a number of heavy metals lead, chromium, arsenic, zinc, cadmium, copper, mercury and nickel commonly found in contaminated soils. The principles, advantages and disadvantages of immobilization, soil washing and phytoremediation techniques which are frequently listed among the best demonstrated available technologies for cleaning up heavy metal contaminated sites are presented. Remediation of heavy metal contaminated soils is necessary to reduce the associated risks, make the land resource available for agricultural production, enhance food security and scale down land tenure problems arising from changes in the land use pattern.

Heavy Metal Polluted Soils: Effect on Plants and Bioremediation Methods

The sources, distribution and mobility of heavy metals in Zhuzhou City, Hunan Province, China were systematically studied based on environmental monitoring data and random sampling from fields and markets. The significant positive correlations between some pairs of heavy metals total Cd—Hg, total Cu—Pb within the Zhuzhou section of the Xiang River may indicate that they are coming from the same pollution sources with similar pollution channels and removal patterns in the water bodies.

Сейчас она держалась подчеркнуто сдержанно, и это пугало его еще сильнее. - Так в чем же проблема, Фил? - спросил Стратмор, открывая холодильник.  - Может, чего-нибудь выпьешь.

Джабба взглянул на часы. - Странное? - Он начал беспокоиться.  - Можешь выражаться яснее.

Парк был пуст. - Фильтр Х-одиннадцать уничтожен, - сообщил техник.  - У этого парня зверский аппетит.
