Route of Exposure


First Aid

Inhalation (See Ingestion). Fresh air rest. Refer for medical attention.
Skin MAY BE ABSORBED! Transient skin flushing. (Further see Inhalation). Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Slow heart beat. Low blood pressure. Sedation. Low body temperature. Rinse mouth. Refer for medical attention. See Notes.
Notes for ICSC Information
If the pesticide is present under the form of a formulation containing hydrocarbon solvents vomiting may not be induced. Insufficient data are available on the effect of this substance on human health therefore utmost care must be taken. Carrier solvents used in commercial formulations may change physical and toxicological properties. If the pesticide is formulated with an organic solvent also consult ICSC of the solvent used. Acarac Acadrex Azodieno Baam Bumetran Danicut Ectodex Edrizar Istambul Maitac Mitac Ovasyn Taktic Triatix Triatox Topline and Tudy are trade names.

Summary Toxicity Information

PAN Bad Actor
Carcinogen Cholinesterase
Water Contaminant
Developmental or
Reproductive Toxin
Moderate Possible No
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.
2. The acute toxicity reported on this page is of the pure chemical ingredient only and may not reflect the acute toxicity of individual pesticide products. To view acute toxicity of individual products, click on 'View Products' link in the 'Chemical Identification' section above.

Summary of Acute Toxicity for Organism Group
Organism Group Average Acute Toxicity Acute Toxicity Range
HoneybeesSlightly ToxicSlightly to Highly Toxic
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.

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.
