Detection of herbicides in the urine of pet dogs following home l

henry_kuskaApril 23, 2013

This is the time that many rose gardners are also treating their lawns for weeds with weed and feed type products. Recently there has been a discussion of these products causing Rose Rosette Virus type symptoms by unintended "spread" - drift.

There are other considerations:
Exposure to herbicide-treated lawns has been associated with significantly higher bladder cancer risk in dogs. This work was performed to further characterize lawn chemical exposures in dogs, and to determine environmental factors associated with chemical residence time on grass. In addition to concern for canine health, a strong justification for the work was that dogs may serve as sentinels for potentially harmful environmental exposures in humans. Experimentally, herbicides [2,4-dichlorophenoxyacetic acid (2,4-D), 4-chloro-2-methylphenoxypropionic acid (MCPP), dicamba] were applied to grass plots under different conditions (e.g., green, dry brown, wet, and recently mowed grass). Chemicals in dislodgeable residues were measured by LC-MS at 0.17, 1, 24, 48, 72 h post treatment. In a separate study, 2,4-D, MCPP, and dithiopyr concentrations were measured in the urine of dogs and in dislodgeable grass residues in households that applied or did not apply chemicals in the preceding 48 h. Chemicals were measured at 0, 24, and 48 h post application in treated households and at time 0 in untreated control households. Residence times of 2,4-D, MCPP, and dicamba were significantly prolonged (P

That's very sad. What is being done to our planet so people don't have dig out weeds?

And if it has that ugly an effect, that quickly, on a short lived dog, what on earth is it doing to us, with our longer life spans. This is NOT good...

2,4-D is very dangerous stuff. It shouldn't be on the market at all. Here's a little of the info from Beyond Pesticides:

'Beyond Pesticides fully supports the cancellation of this dangerous pesticide which has been associated with a host of adverse human impacts, such as non-HodgkinâÂÂs lymphoma, endocrine disruption, reproductive and developmental effects, as well as water contamination and toxicity to aquatic organisms. The highly toxic chemical can be replaced by cost-competitive and effective management practices widely used in organic agriculture and lawn care. '
