Naled to be aerial sprayed in New Orleans

Naled:
Naled is moderately to highly toxic by ingestion, inhalation and dermal adsorption. Here's what it cando to you:

  • Vapors or fumes of naled are corrosive to the mucous membranes lining the mouth, throat and lungs, and inhalation may cause severe irritation . A sensation of tightness in the chest and coughing are commonly experienced after inhalation.

  • As with all organophosphates, naled is readily absorbed through the skin. Skin which has come in contact with this material should be washed immediately with soap and water and all contaminated clothing should be removed.


  • Persons with respiratory ailments, recent exposure to cholinesterase inhibitors, impaired cholinesterase production, or with liver malfunction may be at increased risk from exposure to naled.


  • High environmental temperatures or exposure of naled to visible or UV light may enhance its toxicity.


  • The organophosphate insecticides are cholinesterase inhibitors. They are highly toxic by all routes of exposure. When inhaled, the first effects are usually respiratory and may include bloody or runny nose, coughing, chest discomfort, difficult or short breath, and wheezing due to constriction or excess fluid in the bronchial tubes.


  • Skin contact with organophosphates may cause localized sweating and involuntary muscle contractions. Eye contact will cause pain, bleeding, tears, pupil constriction, and blurred vision.


  • Following exposure by any route, other systemic effects may begin within a few minutes or be delayed for up to 12 hours. These may include pallor, nausea, vomiting, diarrhea, abdominal cramps, headache, dizziness, eye pain, blurred vision, constriction or dilation of the eye pupils, tears, salivation, sweating, and confusion.


  • Severe poisoning will affect the central nervous system, producing incoordination, slurred speech, loss of reflexes, weakness, fatigue, involuntary muscle contractions, twitching, tremors of the tongue or eyelids, and eventually paralysis of the body extremities.
