Full-text (PDF) | Heavy metal contamination of soil and water due to agricultural and industrial activities is a matter of serious concern, which ultimately reaches humans in the food chain. The sources of these heavy metals can be from bOtil point and non-point sources. The heavy metals when disc
Phytoremediation processes. Phytovolatilization : transfer of pollutants from the soil to the atmosphere. Phytoextraction: transfer of pollutants from the soil and accumulation in the above ground parts of the plant. Phytodegradation: enzymatic degradation of the pollutants in the plant tissue. Enhanced Bioremediation (or
This paper describes phytoremediation on its characteristics, research status, as well as its practical application on management and remediation of contaminated soils with study cases. II. PHYTOREMEDIATION: FUNDAMENTAL PROCESSES. INVOLVED AND CHARACTESTICS. Phytoremediation of contaminated soils is
Phytoremediation is the name given to a set of technologies that use different plants as a containment, destruction, or an extraction technique. Phytoremediation as a remediation each phytoremediation process to provide more detailed, specific information. The purpose of this chapter is to provide site managers with an

Abstract Land application of biosolids, such as sewage sludge or compost, has a great incentive in view of its fertilizer and soil amendment values, unless they con- tain toxic elements.
identify the treatment mechanisms that are used by plants to clean up different sites. Key Words: environment, mechanism, phytoremediation, plants. Introduction. The basic processes for a plant to grow are by developing roots in the soil and producing leaves and woody material. In order to do this, plants use carbon dioxide.
Oklahoma. Introduction. Phytoremediation is the use of plants to partially or substantially remediate selected contaminants in contaminated soil, sludge, sediment, ground water, surface water, and waste water. It utilizes a variety of plant biological processes and the physical characteristics of plants to aid in site remediation.
re- mediation process. Despite these limitations, in cases where large surface areas of relatively immobile con- taminants exist in the surface soils, phytoremediation may be appropriate. General advantages of phytoremediation. To facilitate comparison with physical remediation systems, we have redefined plants as 'solar-
in effect to prevent atmospheric emissions. The slag produced in the distillation process, which usually had high levels of arsenic, cadmium, leads and zinc, used to be discarded into landfills (www.epa.gov/ttn/chief/ap42/ch12/final/c12s07.pdf). The principal air pollutants emitted from smelting operation are particulate
