Oxygen consumption, ATP production and cytochrome c oxidase activity of isolated mitochondria from body-wall tissue of Arenicola marina were measured as a function of sulphide concentration, and the effect of inhibitors of the respiratory complexes on these processes was determined. Concentrations of sulphide between 6 and 9 µmol l-1 induced oxygen consumption with a respiratory control r...

Sir,?In the September issue, 1935, of your esteemed journal it has been mentioned, on page 506, by Dr. N. J. Vazifdar, that after a bomb explosion 'arsenic' enters into the system through the wound and also by inhalation of arsenuretted hydrogen which is evolved in the explosion. A bomb of the type under discussion explodes due to the interaction of sulphide of arsenic with an oxidizing agent s...

The corrosion behaviour of copper was studied in anoxic solutions containing different concentrations of sulphide (10–10 mol L) and chloride (0?1–5 mol L) under stagnant and controlled convective conditions. The main determinants of the structure and properties of the copper sulphide (Cu2S) films formed are the rate of sulphide transport to the surface relative to the rate of its interfacial re...

Dental care is an essential phenomenon in human health. Oral pathogens can cause severe break which may show the way to serious issues in human disease like blood circulation and coronary disease. In the current study, we demonstrated the synthesis and antimicrobial activity of cadmium sulphide and zinc sulphide nanoparticles against oral pathogens. The process for the synthesis of cadmium sulp...

Sulphide gas is an impurity that affects the quality of natural gas, which needs reasonable storage and transportation. In this work, we investigated adsorption structure electronic behavior hydrogen sulfide (H2S), carbonyl sulfur (COS), methyl mercaptan (CH3SH) on sulphide molecules pure vacant ?-Fe2O3(001) surfaces by density functional theory with geometrical relaxations. The results show H2...

Sulphide build-up in pressure sewers has been identified as the main cause for occurrence of odour and corrosion sewer systems. Despite efforts to optimize commonly used control technologies such nitrate iron salts reduce sulphide emission, continuous addition these chemicals is still required. A biocidal agent free nitrous acid can be added intermittently, less frequently, smaller quantities w...

when organic material is decomposed under oxygen-limiting conditions (Nedwell, 1982). (The term sulphide is intended to include undissociated H2S, the bisulphide anion HS− and the sulphide anion S2−.) In marine sediments, sulphide production is enhanced by bacterial sulphate reduction (Jorgensen and Fenchel, 1974; Nedwell, 1982). Species inhabiting intertidal flats or salt marshes are, therefor...
