Because of the high concentration of heavy metals in the sediment sludge produced from industrial wastewater treatment, direct disposal of this sludge in landfill sites will cause serious soil and groundwater pollution.

The ability for heavy metals removal by C. odorata and V. zizanioides grown on contaminated soil and synthetic contaminated soil in experimental pots was investigated. Both contaminated and uncontaminated soils, for preparing the synthetic contaminated soil in this study, were obtained from Mae Sot district, Tak province.

The interactions of methyl orange and two benzidine type azo dyes, Congo Red and Direct Blue 1, with some strong polycations with variable charge densities, having cationic centers in the side chain, were investigated.

This research paper presents the monitoring results of heavy metal pollution across seven sampling stations in Vasai region located on the western coast of India.

Bangalore figures prominently in the world map for its contribution in Information Technology (IT). This phenomental growth over the past decade, has given rise to the generation of lot of electronic waste. E-waste thus generated contains many recoverable metals and non metals along with hazardous wastes and their improper disposal may cause environmental problems.

Aqueous wastes containing thiocyanate (SCN) are frequently encountered from variety of industrial processes. If improperly managed, these wastes can cause reversible or irreversible impact on the soil and water environment. In the process of developing a microbial technology for the SCN removal from aqueous waste, heterotrophic bacterial consortium's capable of degrading the SCN compound were isolated by an enrichment culture technique from activated sludge and garden soil.

An evaluation of response of one disturbed, one rehabilitated and one mature forest soil in lower subtropic China to simulated acid rain (SAR) were studied using a controlled laboratory leaching experiment. Land use change is one of the important factors in controlling soil response to acid deposition.

Natural adsorbent, laterite soil was selected and found to be an effective adsorbent for arsenic removal from arsenic bearing drinking water. The real arsenic bearing groundwater was collected from Nivedita Palli, 24 Paraganas, one of the arsenic affected areas of West Bengal.

This paper represents the result of chemical characteristics such as Dissolved Oxygen, Biochemical Oxygen Demand and Chemical Oxygen Demand during one year at Nanded (Maharashtra) and Rajahmundry (Andhra Pradesh). It was observed that Godavari River at Nanded was more polluted than Rajahmundry.

Activated charcoals have been prepared from the weed like Argemone mexicana L. by using chemical activating agents like Zinc Chloride, Ortho Phosphoric Acid, etc.
