Polycyclic aromatic compounds in curing smoke.

Abstract

The curing smoke, generated by the smouldering of alder chips, from a commercial food smoking plant was investigated with respect to polynuclear aromatic compounds (PAC). Samples were taken from inside the ovens and in the working zone immediately outside them. Analysis showed that considerable amounts of methyl phenanthrenes were present in the smoke as a major part of the PAC content.

A plausibly prebiotic synthesis of phosphonic acids.

The insolubility of calcium phosphate in water is a significant stumbling block in the chemistry required for the origin of life. The discovery of alkyl phosphonic acids in the Murchison meteorite suggests the possibility of delivery of these water-soluble, phosphorus-containing molecules by meteorites or comets to the early Earth. This could have provided a supply of organic phosphorus for the earliest stages of chemical evolution; although probably not components of early genetic systems, phosphonic acids may have been precursors to the first nucleic acids. Here we report the synthesis of several phosphonic acids, including the most abundant found in the Murchison meteorite, by ultraviolet irradiation of orthophosphorous acid in the presence of formaldehyde, primary alcohols, or acetone. We argue that similar reactions might explain the presence of phosphonic acids in Murchison, and could also have occurred on the prebiotic Earth.
