A Pesticide Information Project of Cooperative Extension Offices of Cornell University, Michigan State University, Oregon State University, and University of California at Davis. A tolerance is not required for preplant soil fumigation uses of chloropicrin. For soil fumigation and wood treatment, chloropicrin is packaged in DOT 4BW240 steel cylinders and bulk tanks which may be pressurized. When used as a warning agent for methyl bromide, chloropicrin is packaged along with the methyl bromide in steel cylinders. When used as a structural fumigation warning agent for sulfuryl fluoride, chloropicrin is packaged in small plastic bottles in DOT approved overpacks.
Undiluted chloropicrin is highly toxic by ingestion or direct contact with the skin or eyes.
Inhalation exposure to very high levels, even if brief, can lead to pulmonary edema, unconsciousness and even death. No neoplastic or tumorigenic response was produced by chloropicrin in any species tested by the three routes of exposure. Little information is available about the effects of chloropicrin on bird life. This was the highest dose tested. Effects on Aquatic Organisms Chloropicrin is toxic to fish.
