Phytoremediation: principles and perspectives
نویسنده
چکیده
logical progress. Global development, however, raises new challenges, especially in the field of environmental protection and conservation. Technological ingenuity has enhanced the potential for improving industrial development and rapid progress is being made not only in the field of electronics but also in biological, medical and pharmaceutical applications. In recent decades, increasingly precise knowledge of basic biological functions has brought about biotechnological advances. The possibility to produce transgenic organisms has opened up new fields of experimentation and perspectives for scientific and technological development which go beyond the limits of natural evolution. In summary, the beginning of the XXI century is witness to an irreversible dimension of power, with global concern, in all fields: politics, economics, social and cultural affairs, science and technology. Technological potential and development, however, have not always had beneficial effects [15]. Social and cultural progress fall far behind technological evolution and the over-exploitation of natural resources with short-term, fast profit-oriented management systems has severely damaged the environment. Acute water and soil pollution are evident consequences that call for rapid and efficient solutions. However, in addition, diffuse contamination of large expanses of land [56] is an ever-growing problem that requires sustainable correction measures.

On the Consequences of the Violation of Critical Pedagogy Principles from Iranian EFL Teacher Trainers’ Perspectives
The application of critical pedagogy in educational contexts has received adequate research attention over the last decades. The main focus of this strand of research has, however, been on raising awareness of the educators. Nevertheless, little is known about the consequences of the violation of critical pedagogy principles from EFL teacher trainers’ perspectives. To begin to address this gap ...
متن کاملAdvances in phytoremediation.
Phytoremediation is the use of plants to remedy contaminated soils, sediments, and/or groundwater. Sorption and uptake are governed by physicochemical properties of the compounds, and moderately hydrophobic chemicals (logarithm octanol--water coefficients = 1.0--3.5) are most likely to be bioavailable to rooted, vascular plants. Some hydrophilic compounds, such as methyl-tert-butylether and 1,4...
