Abstract :
Immunoassays and bioanalytical techniques can aid the cost effective detection and quantification of trace contaminants in the environment, food, and human and animal populations. This overview of recent progress shows that rapid advances have occurred in the development and validation, of assays for many contaminants of both industrial and agricultural origin. Promising antibody based techniques such as immunoaffinity chromatography, biosensors, and flow injection immunoanalysis continue to evolve. Such techniques can not only help lower costs and improve efficiency, but can also allow the range of hypotheses that can be tested in many environmental studies to be broadened by permitting the determination of trace residues in small volume samples that would be otherwise difficult to analyze.
