Abstract
The objective of this report is to evaluate the effectiveness of the immunoassay method as an alternative to the gas chromatographic analytical method for rapid screening of dieldrin residues in soils and cucumbers. The values obtained by analysis with both methods were very similar. There was a high correlation of values obtained by both methods in the range of 0.08-0.3ppm from soil samples. A correlation in the values of both methods did not occur in the range of 0.03-0.08ppm. As for the values from cucumber analysis, there was a correlation in the values for the two methods in the range of 0.01-0.05ppm. However, the immunoassay method tended to have larger values than the chromatographic method with substantial variation. Samples with low levels of residues of must be concentrated for accurate analysis with the immunoassay method. It is necessary to include a procedure to remove impurities when the sample is concentrated. Impurities will affect the analysis values.
