Phytoremediation of toxic metals from soil and waste water.
Phytoremediation is an emerging technology, which uses plants and their associated rhizospheric microorganisms to remove pollutants from contaminated sites. This plant based technology has gained acceptance in the past ten years as a cheap, efficient and environment friendly technology especially for removing toxic metals. Plant based technologies for metal decontamination are extraction, volat...
متن کاملPrediction of the Fate of Toxic Metals in Waste Incinerators
The EPA and state governmental agencies are in vestigating means of controlling the emissions of toxic metals from waste incinerators. In order to aid in the development of effective regulations and control stra tegies, an analytical procedure to estimate the emission of metals from combustion devices is being developed.

متن کاملCompost: Beneficial Uses of Compost in Florida Vegetable Crops
Composting is a biological decomposition process where microorganisms convert raw organic materials into relatively stable humus-like material. During decomposition, microorganisms assimilate complex organic substances and release inorganic nutrients. An adequate composting process kills pathogens and stabilizes compost organic carbon before the material is land-applied. In 1997, 27.2 million m...
متن کاملEffect of Municipal Solid Waste Compost on the Growth and Production of Vegetable Crops
Problem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squ...
متن کاملAdsorption studies of toxic heavy metals from waste water by Acacia arabica bark
The adsorption technique using chemically treated powder of bark of Acacia arabica was applied for the removal of toxic heavy metals from polluted waste water. The extent of adsorption found to be dependent on the pH and the time of contact. The adsorbent is effective for the quantitative removal of various toxic metals from the contaminated aqueous sample. The method is quite feasible, economi...
