Chemicals Considered Safe Alone May Trigger Cancer in Combination

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“The way we’ve been testing chemicals — one at a time — is really quite out of date,” Goodson said.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.”

Bad Air In Our Gyms

gym 1With chilly weather settling in and darkness arriving before most people’s workdays end, many of us are shifting our workouts indoors, a practice that is much better for us than abandoning exercise for the winter. But a new study of air quality in gyms raises some interesting questions about whether the places in which we work out are as healthy as they should be.

Science and common sense tell us that exercising in polluted air is undesirable. People who frequently run alongside heavily trafficked freeways and breathe great lungfuls of exhaust have been shown to have an increased risk of heart disease, even if they are otherwise in admirably good shape. But few studies systematically have examined the air quality inside gyms.gym 2

Therefore, from the journal Building and Environment, researchers at the University of Lisbon in Portugal and the Technical University of Delft in Holland decided that they would place air-quality monitoring equipment in gyms throughout Lisbon. … Their findings were disquieting. In general, the gyms showed high levels of airborne dust, formaldehyde and carbon dioxide. The concentrations of these substances generally exceeded most gym 3accepted standards for indoor air quality. (No government agency in the United States formally monitors air quality in gyms.) The levels were especially high during evening aerobics classes, when many people were packed into small studios, stirring up dust and fumes and puffing heavily, producing carbon dioxide with every breath. … In sufficient concentrations, these substances can contribute to asthma and other respiratory problems, she said. Almost all of the gyms in the study had levels of these substances that significantly exceed European standards for healthy indoor air standards.
