The disposition of 2,4-dichlorophenoxyacetic acid in rainbow trout

Archives of Environmental Contamination and Toxicology, 1983
This study investigated the dynamics of 2,4-dichlorophenoxyacetic acid (2,4-D) in Salmonid fish. Similar to mammals and marine fish, trout excrete 2,4-D via the urine, with an elimination half-life of 2.4 hr. Although the amount of 2,4-D found in bile was always less than 1% of the dose, the concentration of 2,4-D in bile was greater than any other ...

Preferential removal of 2,4-dichlorophenoxyacetic acid from contaminated waters using an electrocatalytic ceramic membrane filtration system: Mechanisms and implications

, 2020
A selective electrocatalytic ceramic membrane filtration (ECMF) system was developed using molecular imprinting (MI) TiO2@SnO2-Sb (MI-TiO2@SnO2-Sb) anode for selectively eliminating 2,4-dichlorophenoxyacetic acid (2,4-D).

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.

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.

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.

Heterogeneous Fe2CoTi3O10-MXene composite catalysts: Synergistic effect of the ternary transition metals in the degradation of 2,4-dichlorophenoxyacetic acid based on peroxymonosulfate activation

Chemical Engineering Journal, 2019
In this study, a novel Fe2CoTi3O10-MXene (FCT-M) composite was synthesized and employed as a heterogeneous catalyst for the oxidative degradation of 2,4-dichlorophenoxyacetic acid (2,4-D) based on peroxymonosulfate (PMS) activation.

High performance of Ag/BiVO4 photocatalyst for 2,4-Dichlorophenoxyacetic acid degradation under visible light

, 2020
With the aim of exploring and comparing the photocatalytic degradation of 2,4-Dichlorophenoxyacetic acid (2,4-D) under visible light, BiVO4 was synthesized by using coprecipitation and hydrothermal methods and modified with silver nanoparticles (AgNP ...

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.
