Summary

Chloropicrin is used as a broad spectrum fumigant pesticide for pre-plant soil, structural, and enclosed space fumigation.  It is also combined with odourless pesticides to serve as a noisome indicator for potentially hazardous odourless fumes.  Under normal atmospheric conditions, chloropicrin is a volatile, colourless to faint yellow oily liquid, with an extremely irritating and penetrating smell that induces lacrimation.  Exposure is primarily through inhalation, but may also occur through ingestion and dermal or ocular contact.

There are currently no available human data which detail pregnancy outcomes following gestational exposure to chloropicrin and it is therefore not possible to provide an evidence-based assessment of fetal risk. 

Following chloropicrin exposure in a pregnant patient, maternal toxicity is likely to be a major determinant of risk to the fetus.  There are no guidelines regarding the treatment of chloropicrin poisoning during pregnancy.  Where required, treatment should be the same as for the non-pregnant patient.

Where exposure to chloropicrin has occurred, even in cases which did not result in maternal toxicity, enhanced fetal monitoring may be warranted as adverse outcomes have been observed in animal studies.  Discussion with UKTIS is recommended for all cases.
