NOTE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

Route of Exposure

Symptoms

First Aid

Inhalation Cough. Dizziness. Headache. Nausea. Weakness. Visual disturbance. Fresh air rest. Refer for medical attention.
Skin MAY BE ABSORBED! Dry skin. Redness. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Abdominal pain. Convulsions. Shortness of breath. Unconsciousness. Vomiting. (Further see Inhalation). Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
Notes for ICSC Information
Burns with nonluminous bluish flame. Depending on the degree of exposure periodic medical examination is indicated.

Indicates high toxicity in the given toxicological category. Indicates no available weight-of-the-evidence summary assessment. For additional information on toxicity from scientific journals or registration documents, see the "Additional Resources for Toxicity " section of the chemical detail page.
1. PAN Bad Actors are chemicals that are one or more of the following: highly acutely toxic, cholinesterase inhibitor, known/probable carcinogen, known groundwater pollutant or known reproductive or developmental toxicant. NOTE! Because there are no authoritative lists of Endocrine Disrupting (ED) chemicals, EDs are not yet considered PAN Bad Actor chemicals.

Terrestrial Ecotoxicity

Summary of Acute Toxicity for Organism Group

Sorry, no honeybee acute toxicity data available for this chemical. Try related chemicals.

Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.

Click on underlined terms for definitions or go to the Pesticide Tutorial overview page.

Any underlined term with a book icon has additional information.

* Data marked with an asterisk indicates that this chemical is not explicitly listed on the corresponding list. Instead, it belongs to a group of chemicals that IS designated on the list. For example, if an agency assigns a classification of reproductive toxicant to "mercury compounds", that classification is applied to all mercury compounds in the PAN Pesticide database, which are then marked with an asterisk.
