Occurrence and distribution of pesticides in soil at agrichemical facilities in Illinois
Detectable concentrations of pesticides were found in soil samples collected from 49 agrichemical facilities located throughout Illinois. Analysis of 822 soil samples resulted in the detection of 53 pesticides and nitrate; 20 pesticides were found in fewer than 1% of the samples. Most frequently detected were alachlor, atrazine, metolachlor, trifluralin, pendimethalin, cyanazine, metribuzin, metribuzin DA, butylate, and α‐BHC. Chlordane, dieldrin, and DDT, although not distributed at the facilities in recent years, were found in soil samples from more than one third of the sites. Approximately 24% of the pesticide detections occurred in a concentration range between the detection limit and 50 μg/kg, and 79% of all detections were less than 1000 μg/kg.
Pesticides were detected at sampling depths to 4.5 m. However, approximately 50% of all pesticide detections were found in the gravel fill that serves as the parking lot/road base for each facility. No predictable pattern in pesticide occurrence in relation to sampling depth could be determined on the basis of the mobility or persistence of the pesticide.
