Poisoning with 2,4-dichlorophenoxyacetic acid treated by hemodialysis

Archives of Toxicology, 1992
In this paper four patients are presented who had been poisoned by 2,4-dichlorophenoxyacetic acid (2,4-D). The first patient, aged 51 years, had attempted to commit suicide by taking orally 400 ml of a 40% solution of 2,4-D. He was admitted in a coma, 6.5 h after poisoning.

The effect of 2,4‐dichlorophenoxyacetic acid on laying hens

British Poultry Science, 1972
Synopsis Laying hens were fed 2,4‐D, a herbicide, at a rate equivalent to 50 and 150 mg/kg diet from age 28 to 48 weeks. No adverse effects of the treatments were observed upon rate of egg production, egg or yolk weight, egg shell thickness, hatchability or growth rate of the progeny.

Absorption and Excretion of 2,4-Dichlorophenoxyacetic Acid in Man

Xenobiotica, 1974
Abstract1. Absorption and urinary excretion of 2,4-dichlorophenoxyacetic acid (2,4-D) have been studied in six subjects following oral ingestion (5 mg/kg).2. 2,4-D is quickly absorbed; significant quantities were detected in plasma 1 h after ingestion.3.

The Microbial Degradation of 2,4-Dichlorophenoxyacetic Acid in Soil

1988
The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) and the related 2,4,5-trichloro- and 2-chloro-4-methylphenoxyacetic acid (2,4,5-T and MCPA, respectively), are selectively highly toxic to most annual and perennial dicotyledonous species and relatively nontoxic to monocotyledonous plants (Loos 1975a).

Absorption and Translocation of 2,4-Dichlorophenoxyacetic Acid

Botanical Gazette, 1946
1. The pronounced morphological response in plants to 2,4- dichlorophenoxyacetic acid is useful in studies of translocation. 2. The regulator passed upward but not downward through dead segments of stems. 3. Stomata did not appear to be important portals for entry of the compound into the leaves when it was used in aqueous sprays.

2,4-Dichlorophenoxyacetic Acid as a Differential Herbicide

Botanical Gazette, 1944
1. 2,4-Dichlorophenoxyacetic acid was effective as a differential herbicide when applied as an aqueous spray in concentrations of from 250 to 1000 p.p.m. or more. 2. Plants killed by these sprays were dandelion, narrow-leaf plantain, Dutch white clover, chickweed, pigweed, woodsorrel, knotweed, broad-leaf dock, bind-weed, and shiny pennywort.

Biodegradation kinetics of 2,4-dichlorophenoxyacetic acid by aquatic microorganisms

1969
Biological degradation of organic pesticides,1 when provided as the sole substrate, has seldom been examined in aquatic systems. It would be extremely desirable, therefore, to develop a model system from which two pertinent questions could be answered: (a) What is the biological availability of various organic pesticides to degradation, and (b) What is

Spraying of Barley with 2,4-Dichlorophenoxyacetic Acid

Nature, 1959
DR. H. INGVARD PETERSEN has discovered differences in the translocation of the plant growth regulator herbicides applied to cereal plants of different ages1. His autoradiographs show that whereas radioactive 2,4-dichlorophenoxyacetic acid applied to barley at the one- to three-leaf stage is readily translocated to all parts of the plant, including ...
