Purpose: To determine the metallic content of different parts of Gloriosa superba collected from two different locations in Pakistan, and also to assess their nutritious values and toxic levels. Methods: The plant material and soil were collected from two different locations polluted and unpolluted. Wet digestion method was used for the preparation of samples (whole plant and soil) followed by ...

Current methods for the determination of sodium in biological materials are subject to considerable error under certain conditions. Large amounts of Ca, P, or strong acid cause serious interference in the flame photometric method (1, 2) and coprecipitation of Na occurs with methods commonly used to remove Ca and P (3). Whereas analysis of bone for Ca, P, Mg, COz, and a number of other constitue...

Preface In 2005 Norway nominated the brominated flame retardant commercial pentabromodiphenylether (c-PentaBDE) as a persistant organic pollutant (POP) to be evaluated for inclusion in the Stockholm Convention. Based on its Risk Profile developed in 2006 and its Risk Management Evaluation Report developed in 2007, the POPs Review Committee (POPRC) concluded that global action on c-PentaBDE is w...

This year’s cover illustration, reproduced here as figure 1, depicts an image formed by a short-time (1/1000 s) exposure of a non-premixed hydrocarbon flame. The flow is driven by the buoyancy forces generated by the density difference from the combustion heat release and resulting temperature rise. The Reynolds number for this buoyancy-induced, turbulent flow is relatively low, estimated at a ...
