A More Efficient Method for Extracting and Analyzing Pesticides in Baby foods
… and evaluating method efficiency by calculating percent recoveries from the foods. Sample results from the Georgia Department of Agriculture Labs (Tifton, Ga) showed in some cases, a range of 84% to 140% recoveries for some pesticides on the lower end of ppm concentration levels. These recoveries …
