Chemistry & industry
Pharmacology
Metabolism/Metabolites
CDDs are absorbed through oral, inhalation, and dermal routes of exposure. CDDs are carried in the plasma by serum lipids and lipoproteins, distributing mainly to the liver and adipose tissue. CDDs are very slowly metabolized by the microsomal monooxygenase system to polar metabolites that can undergo conjugation with glucuronic acid and glutathione. They may increase the rate of their own metabolism by inducing CDDs induce both phase I and phase II enzymes. The major routes of excretion of CDDs are the bile and the feces, though smaller amounts are excreted in the urine and via lactation. (L177)
Uses & manufacturing
Uses
Used as a post-emergence herbicide against broadleaf weeds and brush in ornamental lawns, recreational turf, sod farms, roadsides, industrial sites, rights-of-way, and forests; [Reference #1]
Dioxins occur as by-products from the manufacture of organochlorides, the bleaching of paper, chlorination by waste and drinking water treatment plants, municipal solid waste and industrial incinerators, and natural sources such as volcanoes and forest fires. (L177, L178)
Use Classification
Herbicides, Plant growth regulators
Environmental transformation -> Pesticides (parent, predecessor)
Applications
DescriptionA commonly used herbicide approved for use in most of the developed world. It is moderately soluble in water, has a low volatility and is quite mobile. It is not usually persistent in soil or sediment systems. It is not expected to bioaccumulate, has a moderate mammalian oral toxicity and may be a skin and eye irritant. It is moderately toxic to mammals, birds and aquatic plants but less so to fish, aquatic invertebrates, bees and earthworms.
UsesHerbicide.
