A recent study has found links between higher levels of exposure to certain chemicals in the home and increased rates of bladder cancer in pet dogs.

The study by researchers at Duke University used silicone devices attached to the collars of over 100 pet dogs to test for the presence of harmful chemicals in the US.

Of the 115 chemicals they were testing for, researchers found 39 in over half of the pets. These included high levels of phthalates and brominated flame retardants, which were strongly linked to signs of bladder cancer in the dogs.

Phthalates are often added to plastics to increase their flexibility and can also be used in cosmetics and toiletries to carry fragrances. Some phthalates have been linked to harmful impacts on human health.

Certain phthalates are classified as endocrine disrupting chemicals (EDCs), which means they can interfere with the body’s sensitive hormone system.

Brominated flame retardants are added to furniture, clothing and electronics to reduce flammability. Some flame retardants are very persistent and can build up in humans and wildlife.

Some have also been shown to disrupt the thyroid, affect brain development and increase the risk of certain cancers.

Although certain phthalates and brominated flame retardants have been restricted in both the US and EU, the researchers say that exposure to these banned substances still takes place as they are still found in older everyday products.

Researchers stated that pet dogs are helpful for studying potential impacts on human health due to living in shared environments.
