Dogs monitor environmental chemicals

In a study conducted by North Carolina State University and Duke University’s Nicholas School of the Environment, researchers attached a silicon tag on dog’s collars to collect the environmental chemicals that people (and dogs) encounter every day. What they found was interesting. The researchers had the dogs wear tags and their owner’s wrist bands for five days, then they compared the results.


What they found was that there were similar patterns of exposure for both dogs and humans. The contaminants were mostly from the home environment. The researchers tested for three main contaminants, pesticides, flame retardants, and phthalates, which are found in plastic food packaging and personal care products.

The advantage of evaluating the contaminants in dogs is that diseases that result from these contaminants may take decades to show up in humans but only years to show up in dogs. According to Matthew Breed, Oscar J. Fletcher Distinguished Professor of Comparative Oncology Genetics, if scientists can develop ways to link dog disease with these exposures, they may find a way to decrease the diseases for both dogs and humans.

I would like to see the tests expanded to other household pets such as cats. This is an interesting study and using the silicon tag is inexpensive and works well.
