Pharmacology and Metabolism

EPN has been found to persist in the tissues of chickens and cats, but is effectively metabolized by rats (#ToxNet).

Discovery and Development

EPN is no longer an active ingredient in any registered pesticide in the United States (#ToxNet).

Health Effects

Symptoms of exposure to ENP can include convulsions, headaches, dizziness, sweating, unconsciousness, wheezing, muscle cramps. If ENP is ingested, symptoms can extend to abdominal cramps, nausea, vomiting, and diarrhea (#PAN Pesticides Database). High levels of ingestion could potentially cause death (#ToxNet).

Repeated exposure to EPN may not show any side effects, but could be increasingly hazardous (#ToxNet).


Occupational exposure to EPN is most likely to occur through inhalation or dermal contact. To avoid exposure through ingestion, always wash hands with soap and water before eating or smoking, and wash all agricultural food before consuming. Children can also be exposed to EPN by touching their parents contaminated clothes (#ToxNet).

If exposed through inhalation, fresh air and rest is recommended; artificial respiration may be necessary if exposure is great. If EPN gets on clothes or skin, wash with soap and water. If ingested, vomiting should be induced if person is conscious. In all cases, medical attention should be sought (#PAN Pesticides Database).


The World Health Organization (#PAN Pesticides Database) and Superfund ( categorize EPN as an 'Extremely Hazardous' substance.

The Occupational and Safety Health Act lists EPN as an air contaminant.
Under the Federal Insecticide, Fungicide, and Rodenticide Act, EPN is listed as a registered pesticide (
