Recent three-dimensional structures of phosphoryl transfer enzymes in their aluminum fluoride bound state and corresponding biochemical data have shown how diverse biological problems can be investigated using this small inorganic molecule.

Present study was carried out to evaluate the feasibility of conventional rural based defluoridation technique Nalgonda technique, Activated alumina in urban areas. Nalgonda technique is being used extensively due to ease in construction of the reactor, operation & maintenance. This technique is very effective even when the fluoride concentration is above 20 mg/L. However, generation of acid or...

In this study, a novel system for the detection and quantification of organofluorophosphonates (OFP) has been developed by using an optical sensing polymeric membrane to detect the fluoride ions produced upon OFP hydrolysis. Diisopropyl fluorophosphate (DFP), a structural analogue of type G chemical warfare agents such as Sarin (GB) and Soman (GD), is used as the surrogate target analyte. An op...

1. Using male rats, the availability of fluoride from five by products of the aluminium smelting industry was tested. This was done by considering the balance between fluoride administered in controlled diets and the total fluoride content of waste products eliminated over an experimental period of 1 week. 2. Results indicated that yields of available fluoride expressed as percentage weight of ...
