Arsenic, an element of environmental impact, can be incorporated into jarosite–type compounds and remain stabilised within the structure under a wide range of environmental conditions. In this study, a sample of ammonium–arsenic jarosite was synthesised by precipitation in sulphate medium at controlled pH of 1.2–1.8. The behaviour of arsenic during the thermal and chemical decomposition of jaro...

The synthesis and structural characterization of dicationic selenium and tellurium analogues of the carbodiphosphorane and triphosphenium families of compounds are reported. These complexes, [Ch(dppe)][OTf](2) [Ch = Se, Te; dppe = 1,2-bis(diphenylphosphino)ethane; OTf = trifluoromethanesulfonate], are formed using [Ch](2+) reagents via a ligand-exchange protocol and represent extremely rare exa...

The six elements commonly known as metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloid containing compounds have been used as antiprotozoal drugs. Boron-based drugs, the benzoxaboroles have been exploited as potential treatments for neglected tropical diseases. Arsenic has been used as a medicinal agent and arsphenamine was the main drug used to treat syphilis....

Arsenic is a prominent environmental toxicant and carcinogen; however, its molecular mechanism of toxicity and carcinogenicity remains poorly understood. In this study, we performed microarray-based expression profiling on liver of zebrafish exposed to 15 parts/million (ppm) arsenic [As(V)] for 8-96 h to identify global transcriptional changes and biological networks involved in arsenic-induced...

red mud (rm), a waste tailing from alumina production, (as an important environmental problem), can be used as a strong absorbent pollutant. in this study, the modified red mud (mrm) and pillared clay (pilc) were used for the removal of arsenate from water. the modified red mud (mrm) and pilc complex were characterized using xrd, sem and xrf microanalysis. the adsorption of arsenate on modified...

In this study, we performed microarray-based expression profiling on liver of zebrafish exposed to 15 ppm arsenic [As(V)] for 8-96 h to identify global transcriptional changes and biological networks involved in arsenic-induced adaptive respon...

background: in the present times, arsenic poisoning contamination in the ground water has caused lots of health‑related problems in the village population residing in middle gangetic plain. in bihar, about 16 districts have been reported to be affected with arsenic poisoning. for the ground water and health assessment, simri village of buxar district was undertaken which is a flood plain region...
