industrial wastewaters are of the major sources of heavy metal pollution in the environment. in the middle east, gas and oil industry is the major source of heavy metal pollution and releases significant amounts of metals into the terrestrial and aquatic environment. in this research the capability of the common reed ( phragmitis australis ) in absorbing heavy metals cd, pb and v from the waste...

Plant remains from archaeological sites reflect many aspects of the relationship between people, plants, and the environmentin which they lived. Plant macroremains—seeds and wood that are visible without a microscope—can address a widerange of questions. The most basic include what crops were grown? What was used for fuel? Do any of the plants comefrom distant lands? Examples from fourth and th...

pollution of the soil environment with toxic materials from fossil burning, mining and smelting of metalliferous ores, disposal of sewage, fertilizers and pesticides, etc. has increased dramatically since the onset of industrial revolution. application of plants with ability of absorbing heavy metals is a low-cost alternative for eliminating soils from heavy metals. phytoremediation uses plants...

The rapid industrial development and agricultural growth and the indiscriminate production of pollutants have faced problems for human societies and the environment. Accumulation and pollution of heavy metals in the environment are the main important problems that as a result of human activities through extraction from ore and processing for various applications has led to the release of these ...
