Samples were analysed for traces of a substance called TCPY, a breakdown product of chlorpyrifos.
The new test, for example, measures a key breakdown product, phenyl acetate, which is excreted in the urine.
The major breakdown product of microbial decomposition is carbon dioxide, which is formed by respiring aerobic organisms.
Choline is obtained by the active uptake of extracellular choline, a breakdown product of previously released acetylcholine.
Even today, sea lion blubber contains high levels of DDE, a toxic metabolic breakdown product of DDT.
Hyperbilirubinemia (an increased amount of bilirubin, a breakdown product of hemoglobin, in the blood) may lead to neurological deficits.
The second test is a urinary assay for the norepinephrine metabolite, 3-methoxy-4-hydroxy-phenylglycol or MHPG, another breakdown product of a brain chemical.
At first, we thought 28K was a piece of the Rh molecule — some kind of breakdown product of the Rh, a contaminant that showed during testing.
Because chemicals like polychlorinated biphenyls (PCB's), dioxin and dichlorodiphenyl dichloroethene (DDE), a breakdown product of DDT, are fat soluble, they are not readily excreted from the body.
Neither of the readings for the two chemicals detected, metalaxyl and a chemical breakdown product of dacthal, were above drinking water maximums.
Another researcher reported that some studies showed that women who had high levels of DDE, the DDT breakdown product, had more difficulty breast-feeding than others.
