Soil microorganisms metabolize the herbicide p-chlorophenoxyacetic acid into 2-hydroxy-4-chlorophenoxyacetic acid, and Aspergillus niger converts phenoxyacetic acid into the o- and p-hydroxy derivatives.
A pseudomonas, capable of utilizing 4-CPA as a sole carbon source, was isolated from soil. The following compounds were identified in culture extracts: 4-chloro-2-hydroxyphenoxyacetate, 4-chlorocatechol, beta-chloromuconate, gamma-carboxyethylene-delta-alpha-beta-butenolide. It was found that beta-chloromuconolactone was unstable in aqueous solution and hydrolyzed easily to the corresponding beta-hydroxy analog.

If any symptoms of illness occur during or following inhalation of spray, remove victim from contact with the material for at least 2 to 3 days. Allow subsequent contact with chlorophenoxy compounds only if effective respiratory protection is practiced. /Chlorophenoxy compounds/
Flush chemicals from eyes with copious amounts of clean water for 10 to 15 minutes. If irritation persists, an ophthalmologic examination should be performed. If substantial amounts of chlorophenoxy compounds have been ingested, spontaneous emesis may occur. ...Administer intravenous fluids to accelerate the excretion of chlorophenoxy compounds, and to limit concentration of the toxicant in the kidney. A urine flow of 4-6 mL/minute is desirable. Intravenous saline/dextrose has sufficed to rescue comatose patients who drank 2,4-D and mecoprop several hours before hospital admission. Caution: Monitor urine protein and cells, BUN, serum creatinine, serum electrolytes, and fluid intake/output carefully to ensure that renal function remains unimpaired and that fluid overload does not occur. /Chlorophenoxy compounds/
If ... ingested, spontaneous emesis usually occurs. Ordinarily, this empties the stomach as effectively as intubation & lavage. If vigorous emesis has not occurred, measures should be taken to empty the stomach and limit gastrointestinal absorption by gastric intubation, aspiration, and lavage, following placement of a cuffed endotracheal tube. Repeated administration of charcoal at half or more the original dosage every 2-4 hours may be beneficial. If gastric aspiration and lavage is not performed due to delay in treatment, and if the patient is fully alert, administer charcoal, and laxative orally. /Chlorophenoxy compounds/
Translocation and metabolism of (14)C-labeled phenoxyacetic acid in soybeans were evaluated following applications at 3 different sites, primary leaf, cotyledon, and epicotyl. 4-chlorophenoxyacetic acid was phloem-mobile compound 63.4% of the parent acid remained after 2 days. The factor which accounted for the difference between phloem transport of (14)C phenoxyacetic acid and the hormone-type compound is binding to receptor protein. (14)C phenoxyacetic acid appears to be more phloem mobile because it is not inactivated at the source, in the transport path, or at the sinks either by rapid and extensive in vivo degradation or by binding to plant growth regulator receptor proteins.
The differential renal excretion of phenoxyacetic acid, 2-chlorophenoxyacetic acid, 4-chlorophenoxyacetic acid, and herbicides 2,4-D and 2,4,5-T was measured in chickens by the method of Sperber (1948 and 1954). Doses of approximately 50 and 100 mumol of either test compound were infused during 3 min into a leg vein and the amounts excreted by the 2 kidneys determined during consecutive 15-min periods. At the lower dose level the mean apparent tubular excretion fractions (EF) of the compounds, expressed as per cent of the dose, where 16.5, 22.9, 12.8, 11.3 and 4.2, respectively. All the values except that for 2,4,5-T are sufficiently high to be indicative of tubular excretion. On increasing the dose, the EF values decreased, thus suggesting the involvement of a saturable mechanism. The test compounds depressed the excretion of phenol red, the effect being most marked with 2,4,5-T.
Tritiated chlorphenesin carbamate was quickly absorbed by the dog, with peak blood levels appearing 2-3 hr after injection. One of the urinary metabolites was p-chlorophenoxyacetic acid.
