chemicals 2New research shows that 50 chemicals people are exposed to daily, all of which are considered non-carcinogenic, may cause cancer when combined.

The series of studies which comprise the research, worked on by 174 scientists in 28 countries, considered links between 85 common chemicals thought not to cause cancer. Fifty were found to interact at ordinary environmental exposure levels to support cancer-related mechanisms. 

“This research backs up the idea that chemicals not considered harmful by themselves are combining and accumulating in our bodies to trigger cancer and might lie behind the global cancer epidemic we are witnessing,” said Dr. Hemad Yasaei, a cancer biologist at Brunel University London, in a press release. “We urgently need to focus more chemicals 3resources to research the effect of low dose exposure to mixtures of chemicals in the food we eat, air we breathe and water we drink.”

The Nova Scotia-based Getting To Know Cancer put together the task force of scientists for the first-of-its-kind look at the effects of combinations of common chemicals thought not to cause cancer. The organization gathered scientists two years ago as part of the Halifax Project, which created task forces of scientists researching the complexities of cancer and its causes.

William Goodson III, a senior scientist at the California Pacific Medical Center, said the results of the studies show not only chemicals 1that chemicals safe on their own are combining in the air to form mixtures that can cause cancer, but that the way chemicals are tested for safety needs to be changed.

“The way we’ve been testing chemicals — one at a time — is really quite out of date,” Goodson said. “Every day we are exposed to an environmental ‘chemical soup,’ so we need testing that evaluates the effects of our ongoing exposure to these chemical mixtures.”

Pepsi-One-and-Cancer

The agency is investigating the ingredient after a Consumer Reports study found many sodas with levels of 4-methylimidazole that are questionable. The report included 12 soda brands from five different makers sold in California. Research on the safety of the caramel coloring isn’t consistent, but in California, the chemical is considered a carcinogen and is supposed to be labeled if the amount passes a threshold of 29 micrograms. In the Consumer Reports analysis, two soda products — Pepsi One and the beverage Malta Goya — had levels beyond 29 micrograms. And according to the Associated Press, companies like Coke and Pepsi have asked suppliers to reduce the labeling threshold. The Food and Drug Administration (FDA) says it is looking into the matter, but so far, the Associated Press reports, decades of studies on the chemical show there is no known health risk to humans. The FDA will consider new data to determine whether consumers’ exposure to the coloring is affecting their health. The chemical can also form when meat is grilled and coffee beans are roasted.
