Analytical Chemistry Solving Problems in Pollution and Aquaculture

This paper describes the use of analytical chemistry as a problem-solving tool. Examples include the identification of cyeloparaffins in a drilling mud oil, which indicates that the oil is a product of hydrogenation, the identification of diphenyl alkyl phosphites and phosphates in coated-wire lobster traps, the use of fluorescence spectra for distinguishing between clams (Mya arenaria) from different localities, and graphical presentation of multidimensional data such as fatty acid composition of trout phospholipids, as an aid in data interpretation.
