Diquat is a yellow crystalline solid dissolved in a liquid carrier. It is a water emulsifiable liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. It can cause illness by inhalation, skin absorption and/or ingestion. It is used as a herbicide.

Dibromide salt: Yellow crystals. Commercial product may be found in a liquid concentrate or a solution. [NIOSH]

Diquat: HSNO Approval: HSR006720 Approved with controls

INHALATION: No appreciable vapor pressure. Prolonged contact with spray or mist may cause oral and nasal irritation. EYES: Irritation. SKIN: Irritation. INGESTION: Vomiting, diarrhea, general malaise. Possible kidney and liver damage, dyspnea, and pulmonary edema. With large doses there may be tremors or convulsions. OTHER: May be fatal if swallowed, inhaled, or absorbed through skin. (USCG, 1999)

Poisoning usually occurs after toxic ingestion, e.g., attempted suicide. Symptoms of poisoning include acute renal failure, shock, convulsions, delirium, and skin burns. Diquat does not cause progressive pulmonary fibrosis as seen after paraquat poisoning. [EPA Pesticides, p. 111] Among the many herbicides in use, only the bipyridyl compounds have appeared to produce hepatic injury in humans. Even these agents have produced hepatic injury only as the result of ingestion of large amounts, not because of environmental contamination and questionably as the result of occupational exposures. [Zimmerman, p. 415]

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

Volatile

Herbicides that remove leaves from trees and growing plants. They may be either organic or inorganic. Several of the more persistent types have been used in military operations and many are toxic. (From Hawley&apos;s Condensed Chemical Dictionary, 11th ed)

Pesticides used to destroy unwanted vegetation, especially various types of weeds, grasses (POACEAE), and woody plants. Some plants develop HERBICIDE RESISTANCE.
