Tetramethyl thiuram disulfide (thiram) is an important dithiocarbamate bactericide; it has been widely used for the control of various diseases in fruits, vegetables, seeds and food grains. However, also causes environmental pollution problems poses a threat to human health certain extent. Thiram induces tibial dyschondroplasia (TD) by causing oxidative stress antioxidants imbalance growth plat...

Abstract To determine the factors that control oxygen content of sulphide melts in upper mantle, mono-sulphides were equilibrated with mantle peridotite assemblages, varying FeO and NiO contents, between 3 13 GPa 1300 to 1819 °C. Carbonates added as a flux use graphite capsules allowed fugacities ( f o 2 ) be estimated for most experiments. Sulphide melt O concentrations range 0.2–3.7 wt. %, co...

Hussainsagar lake in the heart of Hyderabad city receives domestic sewage and industrial effluents through five streams draining the catchment area of 245 sq. km around the lake. Lake used to receive untreated industrial effluents through streams during 1970 -1990. Over the years, sediments in the lake have adsorbed the heavy metals and have reported elevated concentrations. Metal speciation of...

An analysis of the geochemical distribution of selected trace metals among various geochemical phases of the sediments in the Oman Margin was carried out using a sequential extraction technique. The present study showed that most Cu in abyssal sediment is associated with only oxidisable mainly organic and sulphide bound metals with insignificant bound to exchangeable, carbonates, easily/moderat...

1-(2-Pyridylazo-2-naphthol), PAN, has been introduced and extensively employed as a reagent in radioanalytical chemistry in our laboratories. An earlier communication dealt with the determination of micro amounts of Cu(II) by displacement of labelled zinc from Zn-PAN complexl'. The present work is intended to develop a similar method employing Zn-PAN complex for the determination of mercury(II)...

Analytical procedures for the determination of selected speciation forms of sulphur have been proposed. The method for conversion of sulphur sols into homogeneous solutions sols allowing simultaneous determination of sulphur either in model solutions or in sols environmental samples has been described. The methods for determination of sulphur sols, elemental sulphur, soluble and insoluble sulph...
