| Abstract: | Abstract An activated charcoal bed unit (ACBU) was constructed using teflon stock. The unit duplicated the flow and bed design of a commercially available tractor mounted filter for removing pesticides from the air. Eight pesticides (4 herbicides and 4 insecticides) were used to test the retention efficiency of ACBU over a 12–48 h period with the ACBU in place. Polyurethane foam (PUF) plugs in series trapped any residual pesticide that came through the ACBU. The ACBU retained 93–100% of the pesticides tested. The unit thus provides an efficient mechanism for removing airborne pesticides. |
