dicamba toxicity

acute toxicity Symptoms of poisoning with dicamba include loss of appetite (anorexia), vomiting, muscle weakness, slowed heart rate, shortness of breath, central nervous system effects (victim may become excited or depressed), benzoic acid in the urine, incontinence, cyanosis (bluing of the skin and gums), and exhaustion following repeated muscle spasms ( 2 , 3 ). Dicamba poisoning may also trigger the onset of anorexia, vomiting, and central nervous system excitability and depression. Dicambe is widely used in Europe, Australia and the U.S. Spills or other releases of 1,000 pounds (454 kg) or more of dicamba must be reported to the National Response Center: (800) 424-8802. 67 When researchers fed dicamba to newly emerged honey bees ( Apis mellifera ) at concentrations up to 1000 ppm, no significant difference in survival was observed.68 The acute contact 48-hour LD 50 for dicamba to honey bees was greater than 90.65 μg/bee and the acute oral LD 50 was … By dermal application, the LD. Likewise, the chemical affects the heart, digestive tract, and the muscular system. The lowest oral median lethal dose (LD. Dicamba increases the risk of muscle weakness, repeated muscle spasms and general exhaustion. The systemic herbicide is also detrimental to the skin and eyes.Blackcurrant seed oil sources, health benefits and usesSandimmune – uses, health risks, and side effects at NaturalPedia.comMonsanto, DuPont unleash highly toxic, drift-prone dicamaba herbicide, endangering public health and North America’s food supplyDicamba is particularly harmful to the respiratory tract and the central nervous system. decomposes at approx. 392 degrees F (200 degrees C) (Residues of dicamba on treated plants can disappear through exudation from the roots into the surrounding soil, metabolism within the plant, or by loss from leaf surfaces (EXTOXNET: The Extension Toxicology Networkphenoxy herbicide; benzoic acid derivative; carboxylic acid When dicamba was ingested daily in the feed, the concentrations in different organs reached a steady state within 2 weeks. At sufficient concentrations, the plant outgrows its nutrient supplies and dies. Cardiopulmonary resuscitation is to be performed on victims who fell unconscious after inhaling the substance. This means that EPA believes that water containing dicamba at or below this level is acceptable for drinking every day over the course of one's lifetime, and does not pose any health concerns. The oral LD50 for dicamba in rats is 757 to 1,707 mg/kg, 1190 mg/kg in mice, 2000 mg/kg in rabbits, and 566 to 3,000 mg/kg in guinea pigs (The EPA has established a Lifetime Health Advisory (LHA) level of 200 micrograms per liter (ug/l) for dicamba in drinking water. Dicamba may cause reproductive and developmental toxicity, neurotoxicity, and acute toxicity. People exposed in this way should thoroughly flush their eyes with running water for 15 minutes. Dicamba's toxicity to honey bees ranges from moderately toxic to practically non-toxic, based on U.S. EPA values. Dicamba exposure may result in labored breathing and irritation of the nasal and lung passages.Dicamba triggers slowed heart rate, urinary incontinence and cyanosis as well as skin and eye irritation.The systemic herbicide is also associated with an increased risk of muscle weakness, repeated muscle spasms, and general exhaustion. 50) was approximately 1600 mg/kg bw in female rats.

Dicamba is volatile and presents a drift hazard. The paper outlines the environmental fate and toxicology of dicamba, a systemic herbicide used in agricultural, industrial, and residential settings to control broadleaf weeds and woody plants. Acute toxicity: Dicamba is slightly toxic by ingestion and slightly toxic by inhalation or dermal exposure [7]. Results from animal testing have indicated that dicamba is a compound of low acute toxicity; however, effects of acute exposure to humans have been reported to include appetite loss, weight loss, vomiting, depression, muscular weakness, and even death if sufficient quantities are inhaled, ingested, or absorbed through the skin.
