“…Hertz et al showed an 80% loss due to absorption of a 1 ppb aqueous PAH over four hours while being stirred in a glass vessel. 4 Although recoveries can be improved by either silanizing the collection vessel 5 or immediately freeze-drying the samples 4 and storing them in the dark until analysis, 6 only an in situ analytical method can truly represent the analyte in its native environment.…”

A field portable, single exposure excitation-emission matrix (EEM) fluorometer has been constructed and used in conjunction with parallel factor analysis (PARAFAC) to determine the sub part per billion (ppb) concentrations of several aqueous polycyclic aromatic hydrocarbons (PAHs), such as benzo(k)fluoranthene and benzo(a)pyrene, in various matrices including aqueous motor oil extract and asphalt leachate. Multiway methods like PARAFAC are essential to resolve the analyte signature from the ubiquitous background in environmental samples. With multiway data and PARAFAC analysis it is shown that reliable concentration determinations can be achieved with minimal standards in spite of the large convoluting fluorescence background signal. Thus, rapid fieldable EEM analyses may prove to be a good screening method for tracking pollutants and prioritizing sampling and analysis by more complete but time consuming and labor intensive EPA methods.

“…The analysis of complex aqueous mixtures of trace organic compounds usually involves preliminary isolation and concentration steps (1)(2)(3)(4)(5)(6). Any preliminary separation should be selective, while minimizing analyte loss.…”

There are many techniques for water analysis. A great deal, however, can be determined by a few physical and chemical tests. This article deals with fresh water analysis primarily and may not be suitable for saline water. Tests for physical properties include: temperature, specific conductance, color, turbidity, taste and odor, dissolved solids and suspended solids, and pH. There are many principal mineral constituents and gases that can be determined. Information is given for the determination of alkalinity, acidity, hardness, sodium and potassium, chloride, sulfate, nitrate and nitrite, fluoride, phosphate, boron and borates, silica and oxygen. Analysis of minor mineral constituent and gases, BOD, detergents, pesticides, and radioactive materials, both artificial and natural, and identification of bacteria round out the article.
