Effects of brine treatment on pesticide residues during recycling of pickling brine.
The effects of 2 pickle brine recycling treatments on residues of selected insecticides, herbicides, and fungicides are presented. Residues were determined in raw and brined cucumbers, in untreated brine, and in brine following pasteurization or chemical (NaOH) treatment. The samples were extracted with acetone, partitioned into methylene chloride, cleaned up by gel permeation chromatography, and quantitatted by gas-liquid chromatography using nitrogen/phosphorus, electron capture, and flame photometric detectors.
