Route of Exposure |
Symptoms |
First Aid |
|
---|---|---|---|
Inhalation | Cough. Laboured breathing. Vomiting. Weakness. | Fresh air rest. Refer for medical attention. | |
Skin | Redness. | Remove contaminated clothes. Rinse and then wash skin with water and soap. | |
Eyes | Redness. Pain. Blurred vision. | First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor. | |
Ingestion | (Further see Inhalation). | Rinse mouth. Refer for medical attention. | |
Notes for ICSC Information | |||
If the pesticide is present under the form of a formulation containing hydrocarbon solvents vomiting may not be induced. Carrier solvents used in commercial formulations may change physical and toxicological properties. Banvel Banex Dianat Fallowmaster Mediben Metambane Tracker Trooper and Velsicol are trade names. If the pesticide is formulated with an organic solvent also consult ICSC of the solvent used. |

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. | |||

Honeybees | Slightly Toxic | Slightly to Moderately 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. |

Click on underlined terms for definitions or go to the Pesticide Tutorial overview page. Any underlined term with a book icon * 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. |
