“…Pentachlorophenol (PCP), which is commonly used as a wood preservative, can contain chlorinated dibenzo-p-dioxins (CDDs) as impurities (1). Technical PCP has been reported to contain chlorodiphenyl ethers, chlorodibenzo-p-dioxins, chlorodibenzofurans, and hydroxychlorodiphenyl ethers; the octachlorodibenzo-p-dioxin (OCDD) content of technical PCP is typically 500-1500 ppm (2). Purified PCP Dowicide EC-7 (trademark of The Dow Chemical Co.) contains much lower levels of these impurities.…”

single-time assays of trihalomethanes in drinking water. Furthermore, there is sufficient variation in even a large system so that a simple harmonic model cannot allow prediction of trihalomethane concentrations from one day to the next. If a maximum contaminant level for these compounds in drinking water is to be monitored, recognition of the 24-h variation is essential, but in addition the larger contribution of as yet undefined sources of day-to-day variability must be taken into account. The observed day-to-day variability may be of a systematic nature, i.e., possibly reflecting certain weekly cycles in water usage or in operations of the water treatment plant. Or, it may be simply a part of the broad scale irregular fluctuations known to be typical for the day-to-day behavior of river flow, ambient air and water temperatures, influencing the amount of humic material available for reaction with chlorine and the rate of trihalomethane formation. This question, although it cannot be answered with certainty given the available data, is, however, important, since it has a bearing on the potential predictability of trihalomethane concentrations in drinking water. An investigation is contemplated to address this matter. Literature Cited(1) Fed.

“…Numerous methods have been published for the determination of chlorinated dibenzo-p-dioxins (CDDs) in pentachlorophenol which is now widely used as a wood preservative and fungicide. Recent techniques used for this analysis have included gas chromatography with mass spectrometry, flame ionization or electron capture detection, and liquid chromatography with ultraviolet detection (1)(2)(3)(4)(5)(6). The methods employing gas chromatography-mass spectrometry offer the greatest specificity and sensitivity.…”

A rapid liquid chromatographic method for the determination of hexa-, hepta-, and octachlorodibenzo-p-dioxins in pentachlorophenol is described. The nonphenolic impurities are quantitatively isolated from the sample matrix by an extraction-column chromatography procedure that permits the chlorinated dibenzo-p-dioxins to be determined by reversephase partition liquid chromatography. Sample concentrates are analyzed in a 12-min separation with detection limits of 100 parts per billion. The entire analysis may be completed

All aspects of the use of mass spectrometry for the identification and quantitation of chlorodibenzo-p-dioxins are critically reviewed. The mass spectra obtained by various ionization methods are discussed. Numerous mass spectral techniques and cleanup procedures are covered, with emphasis on their interrelationships. These techniques have been applied to the determination of chlorodibenzo-p-dioxins in many different matrices, including product materials, such as chlorophenols and phenoxy acid herbicides, and toxicological and environmental materials such as cattle, fish, rodent and human tissues. Formation and degradation studies, which include thermal chemistry, photochemistry and chemical stability and degradation, are presented. Numerous considerations in the handling and quantitation of chlorodibenzo-p-dioxins, such as interferences, detection limits and recovery studies, are evaluated.
