EFFECTS OF DRYING AND DURATION OF STORAGE ON THE EXTRACTABLE ATRAZINE CONTENT OF SOIL SAMPLES

The extractable atrazine content of soil samples was reduced by drying at 45 °C for 24 h. Dried samples originally containing 1 ppm atrazine showed no further significant loss of atrazine when stored up to 180 days at room temperature; however, there was significant loss between 180 and 360 days. Dried samples originally containing 10 ppm atrazine showed significant loss after 90 days of storage. © 1979, American Chemical Society. All rights reserved.
