in recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. the presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. the coal mine area in bokaro is one of the “toxic hotspot” in india. bacteria have evolved uptake and efflux mec...

Metal bioaccessibility is an alarming issue in croplands of mining sites due to overloading of toxic metals. Hence, the present study is aimed to determine the overloading of toxic metal in croplands across the Tawag village, Hutti, Raichur, India. Correspondingly, to identify the soil bacterial growth, physiological oxidative stress enzyme activity and surface macromolecular functional group e...

Successful in vivo chelation treatment of metal intoxication requires that a significant fraction of the administered chelator in fact chelate the toxic metal. This depends on metal, chelator, and organism-related factors (e.g., ionic diameter, ring size and deformability, hardness/softness of electron donors and acceptors, route of administration, bioavailability, metabolism, organ and intra/e...

Galinstan used to prevent edge fracture in rotational rheometers

Metals have been used in clinical practice for hundreds of years and for a variety of indications. Although potent agents whose activity may be adapted by manipulation of their chemistry and that of associated ligands, their use has been limited by toxic effects. There is now a burgeoning series of delivery technologies available which may be adapted to the administration of metal based drugs. ...

The discharge of waste water containing heavy metals like Cr, Cd, Cu from tanneries, electroplating units, metal processing industry etc is the major cause for metal pollution which in turn causes adverse effects in the environment. The conventional methods available for removal of heavy metal are costly and also produce some toxic sludge. This has lead to the invention of new technology like b...

an ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (vigna unguiculata, gossypium hirsutum, jatropha curcas, etc.) was conducted on magnesite mines which had above permissible levels of cadmium and lead. there was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...

Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and persistency of heavy metals in environment. Conventional treatment technologies for the removal of these toxic heavy metals are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the rem...
