In this study, the noncompetitive and competitive adsorption process of copper (II) and nickel (II) ions on the natural zeolite were examined in simulated wastewater in a batch system with respect to concentration, pH and temperature. Optimum pH values were found as 5,0 for adsorption of copper and nickel ions on the zeolite. The effect of initial concentration and ambient temperature on the yield of adsorption was examined at this pH value.

The application of non-targeted NMR methods combined with ICP-AES quantification provided an efficient strategy for detecting residual heavy metals within plant tissues and soil. Importantly, non-targeted metabolomic analysis helped to reveal the relationships between metabolites distribution in hemp tissues and the sequestered metals.

The aim of this study was to demonstrate and evaluate the diatom communities in the copper infected areas readily associated with the Hindustan Copper Limited (HCL) at the bank of the Subarnarekha River. This study was based on three sampling sites commonly designated as high copper (>100 μg.L-1 ), medium copper (≤100 μg.L-1 ) and low copper (≤50 μg.L-1 ) contaminated area. Results indicated the detailed taxonomic description of 31 species that are dominant or less dominant over these contaminated area. Among the identified taxa, 10 were recorded as new to the Jharkhand state.

Vital factor towards increased plant growth was the amount of IAA secreted by the organism (i.e. 2.65 mg IAA/100 ml of the culture filtrate) which is reasonably high in comparison to earlier reports available. Furthermore, PSB has also demonstrated bioremediation potential against harmful heavy metals such as copper, lead, nickel and arsenic by tolerating upto 25 mM indicating it’s prospective in remediating heavy metal contaminated agricultural fields.

Mining, industrial processing, smelting and other industrial activities produce waste waters having toxic levels of Cu which have potential to contaminate natural water and soils. The present study focuses on the removal of Cu(II) from synthetic waste water containing Cu levels in the range of 15.9 to 143 mg L-1 onto Pine needle biochars prepared by pyrolysis at 300 (P300) and 450○ C (P450).

This paper presents the experimental results of the effect of microorganism fertilizer (MF) on growth, yield and accumulation of Cu in lettuce grown on soil contaminated by Cu. The results show that applying MF on soil that has a Cu content of 17.03-106.4 ppm has a positive affect on the height, fresh weight, total chlorophyll content and catalase activity of lettuce grown on that soil.

Especially, the Cu and Zn concentration in fresh leaves of B. integrifolia were within the range of limitation of heavy metals in vegetable by Vietnamese Ministry of Health. Therefore it would be recommended to apply BioGro fertilizer when grow B. integrifolia in Cu and Zn contaminated soil by Cu and Zn.

The objective of the study is to reveal the seasonal variations in the wastewater quality with respect to heavy metal contamination. To get the extent of the heavy metals contamination, wastewater samples were collected from 5 different locations from in and around river Narmada during the Winter, Summer, Monsoon Rainy and Post- Monsoon seasons. The concentration of heavy metals, such as lead, copper, manganese, zinc, cadmium, irons and chromium were determined using Atomic Absorption Spectrophotometer (AAS).

Rhizoremediation is an in-situ remediation approach involving microorganisms for the biodegradation of organic pollutants and various other contaminants in the root zone. Plant roots provide a rich niche for the microorganisms to grow at the expense of the root exudates and in turn microbes act as biocatalysts to remove the pollutants. The harmful pollutants such as: polycyclic aromatic hydrocarbons (PAHs)- pesticides, herbicides etc. are converted to degradable compounds, while heavy metals such as zinc, copper, lead, tin, cadmium etc.

Natural fish bones, that are known to have unique adsorption capacity, have been used in the present work for removal of heavy metals, copper, and cobalt, from wastewater. It has been found that sorption process depends on the initial metal concentration and on the contact time. Laser-induced breakdown spectroscopy (LIBS) as a spectrochemical analytical technique was used for qualitative and quantitative analysis of the water samples. X-ray Fluorescence (XRF), as another spectrochemical analytical method, was exploited to characterize the remediation of wastewater.
