Multicomponent Polycyclic Aromatic Hydrocarbon Analysis of Inland Water and Sediment,quantification of PAHs in the aqueous environment are important for assessment of the potential environmental impact of processes releasing such compounds in aqueous discharges. This paper reports the development of multicomponent PAH analytical methods for inland water and sediment.

Analysis of Headspace Gases for Parts Per Billion Concentrations of Volatile Organic Contaminants i al, 1976). There is a need for rapid and accurate analytical methods because of the potential toxic and carcinogenic effects of these contaminants. These organics may be split into two classes, volatile and less volatile, as suggested by Nowak et al, (1973) each class requiring separate treatment t

Evaluation of Analytical Techniques for Assessment of Treatment Processes for Trace Halogenated Hyd— from public drinking waters is one of the most challenging problems facing the water supply industry today. Conventional treatment technologies are being re-evaluated in this regard, and new and/or modified processes, such as adsorption on activated carbon, are being examined for their effectivene

A System for the Preparation of Organohalogen Reference Materials with Marine Lipid Matrices,es for trace levels of analytes in such natural samples. Natural samples, sometimes enriched by addition of specific analytes, have been used in studies to compare the accuracy of analyses done in different laboratories. Such inter-calibration studies have been reported recently for organochlorine c

Methodology for the Isolation of Polynuclear Aromatic Hydrocarbons for Qualitative, Quantitative, a) and coal-derived fuels (Sharley, 1976). They often interfere in the analyses of PAH because of similar chromatographic characteristics. Therefore, in choosing a method for the analysis of PAH in an environmental sample, it is important to consider the source of the PAH and the possible presence of heteroatom aromatics.

Analysis of Mirex in Lake Sediments: Problems and Solutions,ronmental samples, several laboratories have modified or adapted existing pesticide residue analytical methodologies (Task Force on Mirex, 1977). Due to the increasing demand on mirex analysis, methods that are more convenient or less subject to operational error for routine analysis have been developed.
