The oral LD50 of 2,4-D ranges from 375 to 666 mg/kg in the rat, 370 mg/kg in mice, and from less than 320 to 1000 mg/kg in guinea pigs.WEBToxicological Profile for 2,4-Dichlorophenoxyacetic Acid (2,4-D) Toxicological Profile Information. The ATSDR toxicological profile succinctly characterizes the toxicology and adverse health effects information for the toxic substance described therein.WEBFactors that modify toxicity. Toxicity of 2,4-D to Cyprinus carpio doubled for every 10°C increase in temperature: LC50 decreased from 40.8 mg/L at 17°C to 5.6 mg/L at 39°C (WHO 1989). This would imply a doubling of toxicity for 10°C increase in temperature.WEBEffects that have been reported following oral or dermal exposure to high amounts of 2,4-D include tachypnea, tachycardia, vomiting, leukocytosis, liver and kidney congestion in fatal cases, metabolic acidosis, and neurological effects characterized by sensory and motor abnormalities.WEBOct 31, 2016 · 2,4-D generally has moderate toxicity to birds and mammals, is slightly toxic to fish and aquatic invertebrates, and is practically nontoxic to honeybees. The ester forms of 2,4-D can be highly toxic to fish and other aquatic life.WEBThe herbicide 2,4-Dichlorophenoxyacetic acid (2,4-D) has been used extensively in modern agriculture and, despite its short half-life in soil or aquatic environments, toxicological studies suggest a great potential for inducing undesirable effects affecting non-targeted organisms (Haward 1991).WEBSigns of Toxicity - Animals. Dogs fed 2,4-D exhibited myotonia, vomiting, and weakness; dogs are more sensitive to chlorophenoxy acid herbicides than other animals. 14 In addition, dogs and cats have displayed inappetance, anorexia, ataxia, salivation, diarrhea, lethargy, and convulsions following exposure to 2,4-D, which may include eating ...WEBMay 18, 2022 · These fact sheets summarize the information on occurrence and health effects of the chemicals covered, presenting guideline values where these have been derived and the basis for their derivation, or where guideline values have not been derived, the rationale for not establishing such values.WEBFeb 15, 2019 · List of known side effects. 2,4-D can cause hypolipidemia, which is characterized as having abnormally low levels of lipid in the blood.
