The sulphur isotope content, ôS, of sulphate from two potential pollution sources in Volga-Akhtuba flood plain surface waters was investigated. Isotope compositions of sulphur compound emissions from the Astrakhan Gas Condensate Complex and the Astrakhan Pulp and Paper Mill were significantly different which provided an opportunity to differentiate effects from these two emission sources on nea...

Environmentally and technologically sulphur is a deleterious constitute in coal which makes it unsuitable for use in metallurgical industries unless the sulphur level can be reduced to the tolerable limit. Characterization of the various forms of sulphur and their associations in coal is an essential issue to find and propose a suitable desulphurization method. In this research, to evaluate sul...

An earlier report from these laboratories described the metabolism of carbon and nitrogen compounds by Penicillium notatum in surface culture (Hockenhull, 1946), and some references were made to the utilization of sulphur by this organism. Further work on the latter aspect seemed desirable, especially as penicillin is a sulphur-containing compound. It is the purpose of the present communication...

BACKGROUND Plasma homocysteine (tHcy) is a risk factor for cardio-vascular diseases. Furthermore it has been associated with antioxidative status. Additionally balneotherapeutic sulphur baths have been shown to influence antioxidative status. METHODS 40 patients with degenerative osteoarthrosis were randomised into two equal groups, a treatment group, receiving stationary spa therapy plus dai...

Iron ores are used in blast furnace for the production of pig iron; AGBAJA Iron ore has an estimated reserve of over I billion metric tonnes. Unfortunately, this large reserve cannot be utilized for the production of pig iron due to its high sulphur contents. This work studied the reduction of sulphur content of AGBAJA iron ore. Acid leaching methods were used to reduce sulphur contents of the ...

This paper addresses the variations that presently exist regarding the definition, determination, and reporting of detection limits for volatile sulphur compounds by gas chromatography with pulsed flame photometric detection (GC-PFPD). Gas standards containing hydrogen sulphide (H(2)S), carbonyl sulphide (COS), sulphur dioxide (SO(2)), methyl mercaptan (CH(3)SH), dimethyl sulphide (DMS), carbon...

Context. Sulphur is an element which is formed in the α-process and is easily measured in the gaseous phase in external galaxies. Since it does not form dust, it is the preferred indicator for α-elements, rather than Si or Mg, for which dust corrections are necessary. The measurement of the sulphur abundance in stars is not an easy task, relying mainly on high excitation lines with non-negligib...

THE KEY to improving the native tussock grasslands of the South Island is to obtain good legume growth. In these areas, the main nutrient deficiencies which limit the growth of legumes are sulphur, phosphorus and molybdenum. Sulphur deficiencies are very widespread (Walker et al., 195.5; Lobb and Bennetts, 1958; McLeod, 1961). The manner in which a rational fertilizer programme was formulated f...

It has generally been considered unsafe to give onions, eggs and other sulphur-containing foodstuffs, as well as medicines containing sulphur, to a patient who is receiving the sulphonamide group of drugs. It has been said that the sulphur moiety may lead to sulphsemoglobinsemia which causes cyanosis; the sulphsemoglobin, not being reconvertible into haemoglobin, reduces the oxygen-carrying cap...
