Marihuana Chemistry: Recent advances in cannabinoid chemistry open the area to more sophisticated biological research.

Standardized high-performance liquid chromatography of 182 mycotoxins and other fungal metabolites based on alkylphenone retention indices and UV-VIS spectra (diode array detection).

A comprehensive review of the scientific literature on gunshot residue (GSR) is presented. Aspects of both inorganic and organic GSR are discussed, from formation and distribution, to sample collection, preparation, and analysis using a variety of techniques. The interpretation of GSR results is also considered including issues surrounding the contamination, distribution, and transfer of GSR. Potential problems with ulterior sources of GSR like particles have been reported in the literature. For example, particles from environmental and occupational sources have been highlighted as exhibiting similar chemical and morphological characteristics to GSR. These findings are put into context with regard to interpreting samples. A move toward a “case by case” approach is argued to be more preferable to a “formal” classification system where possible. The analysis of both inorganic and organic compositions of residue samples as well as morphological considerations is considered to be a more ideal approach to GSR analysis, whereever practicable.

Analysis of Gunshot Residue and Associated Materials—A Review

Identification of gunshot residue: a critical review

Cytotoxic fungi--an overview.

A review of all aspects of analysis associated with gunshot residues is provided. This includes a summary of what both inorganic and organic residues are, how they arise and how they may be collected from a variety of substrates. Ways of processing samples to the point of analysis and the means by which they may be analyzed using a variety of techniques is discussed. The techniques described include SEM/EDX, flameless atomic absorption spectroscopy, neutron activation analysis, energy dispersive X-ray fluorescence and some other less common methods for inorganic residues and gas, high performance liquid and super critical fluid chromatography with speciality detectors including mass spectrometry together with capillary electrophoresis, for organic residues. A summary of how the results of such analyses may be interpreted is discussed under the different analytical techniques.

Gunshot residue analysis : a review

3 major components of the toxic fungus Cortinarius speciosissimus have been isolated and their structures determined as cyclic polypeptides. 2 of these compounds have been shown in laboratory animals to cause nephrotoxicity characteristic of Cortinarius mushroom poisoning.

Mushroom toxins of the genus Cortinarius.

Particle size analysis of soils — A comparison of dry and wet sieving techniques

Micellar electrokinetic capillary chromatography of high explosives utilising indirect fluorescence detection

A standardized method is described to aid in identification of species of Cortinarius subgen. Dermocybe based on the presence of pigments and fluorescent compounds. Herbarium material, in one case over 100 years old, was used. With examples it is shown how previously incorrectly identified material can be re-determined. Species that are currently thought to be synonymous could not be differentiated. One collection was shown to be a mixture of two species.
