[7] In Australia, DCPA is the active ingredient in agchem company Farmalinx's herbicide called Dynamo 750.

[10] On August 6, 2024 the United States Environmental Protection Agency announced the emergency suspension of all registrations of the pesticide in the United States due to concerns regarding embryo-fetal toxicity[11] According to the EPA, when pregnant mothers are exposed to DCPA their babies could experience changes to hormone levels, and these changes are generally linked to symptoms such as low birth weight, impaired brain development, decreased IQ, and impaired motor skills later in life, some of which may be irreversible.

In the vapor phase, DCPA should react slowly with hydroxyl radicals with an estimated half-life of 36 days.

[9] Some of these locations included the Apalachicola, Colorado, Mobile, Savannah, and Pee Dee River Basins in both bass and carp.

[14] Fish collected from different locations throughout the United States are often contaminated by DCPA if they are near agricultural areas that use or have used it as an herbicide.

[20] Studies show that DCPA and TPA may cause detrimental health effects in laboratory animals, mainly weight loss and diarrhea occurring at doses near 2000 mg/kg/day.

Decreased motor activity and poor sight reflexes were also observed in a study on New Zealand white rabbits that were exposed to DCPA.

Alternatively, a 1963 study using pure DCPA did not produce any negative results when administered to albino rats.

[9] Studies have demonstrated that DCPA acts as a chemical disruptor by interfering with microtubule formation in exposed cells.

[21] Exposure to DCPA has shown damaging effects in the adrenal glands, kidneys, livers, thyroids, and spleens of laboratory animals.

[9] According to the US EPA, when pregnant mothers are exposed to DCPA their babies could experience changes to hormone levels, and these changes are generally linked to symptoms like low birth weight, impaired brain development, decreased IQ, and impaired motor skills, which may be irreversible and lifelong.

The Safe Drinking Water Act also calls for the EPA to choose five contaminants from the list and determine whether regulation is necessary.

“DCPA is so dangerous that it needs to be removed from the market immediately,” said Assistant Administrator for the Office of Chemical Safety and Pollution Prevention Michal Freedhoff.
