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.

2,4-Dichlorophenoxyacetic Acid

2000
Abstract 2,4-Dichlorophenoxyacetic acid (2,4-D) is one of a group of chlorophenoxy compounds widely used as herbicides. The chlorophenoxy herbicides act as synthetic auxins (plant hormones) that alter the metabolism and enhance the growth of plants. The abnormal growth interferes with the transport of nutrients and destroys the plant.

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).

3,5‐Dichlorophenoxyacetic acid as a growth retardant

Annals of Applied Biology, 1970
SUMMARYTomato seedlings, grown in the glasshouse, were sprayed with solutions of 3,5‐dichlorophenoxyacetic acid as sodium salt at 2 times 10‐5, 4 times 10‐5 and 10‐4 M. The treated plants became dark‐green, dwarfed, and compact. After 6–7 weeks normal growth was resumed. Measurements and analytical data on treated and control plants are presented.

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.

Phytotoxicity of Histamine, Arsenic Acid, and Dichlorophenoxyacetic Acid, and Methods of Testing

Nature, 1952
THE recent paper by Allen and Skoog1 on the phytotoxicity of imidazoline derivatives prompts this report on tests which have been made with the related β-imidazolyl-4-ethylamine (histamine). Some comments are added concerning the suitability of methods for measuring toxicity.
