ABSTRACT:
A method for determining the amount of photoreactive polynuclear aromatic compound in a sample is described. A sample containing an unknown amount of a photoreactive polynuclear aromatic compound is mixed with a known quantity of a polyhalogenated organic compound and exposed to light of a known wavelength for a known length of time. The quantity of the photoreaction product which results from the light exposure is measured by absorption spectroscopy. Comparison of the absorption measurement to a standard curve allows determination of the concentration of the photoreactive aromatic compound. The simplicity of the method makes it suitable for on-site testing. The method can be used to test for photoreactive compounds in various media, such as soil, aqueous samples, and oil.
