Use of beetles in forensic entomology.

Beetles (Coleoptera) have been recognised as providing significant entomological evidence in the medico-legal field, particularly with reference to dry human skeletal remains in the later stages of decomposition. The Dermestidae (skin beetles) and Cleridae (bone beetles) have been found as the most common types infesting exposed human remains and providing evidence in estimating the minimum postmortem interval (PMI).

Isolation of an unknown compound, from both blood of Bhopal aerosol disaster victims and residue of tank E-610 of Union Carbide India Limited--chemical characterization of the structure.

A total of more than 28 chemical entities/reaction products in the form of gases, vapour and particulate matter were reported from the tank E-610 of methyl isocyanate (MIC) storage tank of Union Carbide India Limited on the night of 2/3 December 1984 in Bhopal. In earlier studies, methyl isocyanate and its trimer, with a few other compounds, were reported in the human victims preserved in deep freeze. Randomly selected samples were analysed by gas chromatograph coupled with mass spectrometer (ITD-800, Finnigan MAT, UK).

High performance liquid chromatographic determination of alcohols with reference to body distribution of methanol.

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml.

High performance liquid chromatographic method for the analysis of organophosphorus and carbamate pesticides.

A method has been developed for the rapid quantitative analysis of organophosphorous and carbamate pesticides using HPLC. Good separation was obtained among the four major groups of organophosphorus pesticides [i.e.
