Our Impact

Silent Spring’s contribution to breast cancer prevention and environmental health is unparalleled. Since its founding, the Institute has published more than 100 scientific papers in top journals and its science has informed policies around the country.

Consumers nationwide can purchase furniture free of toxic flame retardants

Our research on the health risks associated with exposure to toxic flame retardant chemicals inside the home led the state of California to revise its flammability standard for furniture. This new standard, which went into effect in 2014, provides fire safety while eliminating the need for flame retardants in furniture. Because California represents such as large market, this affected products across North America.  

In 2017, Silent Spring testified before the U.S. Consumer Product Safety Commission in support of a petition to eliminate an entire class of flame retardants from children’s products, mattresses, upholstered furniture, and electronics. The CPSC ultimately voted in favor of the petition, representing a huge victory for public health.

Boston changes fire code to protect public health

In 2016, scientists at Silent Spring along with other groups persuaded the City of Boston to change its fire code to allow furniture free of flame retardants in public places including hospitals, schools, and colleges. Many manufacturers welcome the changes since adding flame retardant chemicals to furniture can limit product design, reduce the furniture's longevity, and add substantial cost to production. Not only has this change saved institutions hundreds of thousands of dollars, for every college classroom that switches to flame retardant-free furniture, approximately 125,000 students will be spared exposure to harmful chemicals.

“Right to know” becomes more mainstream

Silent Spring has long called for greater sharing of individual results in environmental exposure and biomonitoring studies. Until recently, most researchers have been reluctant to do this for fear it would cause undue harm if the medical implications are unclear. However, the Institute’s pioneering research on the ethics of community-based research has shown just the opposite—reporting back improves science and health literacy, and is an effective tool for translating research into better public health. Today, Silent Spring’s innovative methods for sharing results have become a model for research nationwide.

Crowdsourced study empowers consumers to reduce their exposures

At Silent Spring, we believe knowledge is not just power, but a prescription for prevention. In 2016, we launched Detox Me™ Action Kit—the first crowdsourced biomonitoring study on people’s exposure to common household and environmental toxics. The innovative project is part of a national study to assess the U.S. population’s exposure to potentially harmful chemicals found in everyday consumer items, such as personal care products, food packaging, and household cleaners. Thanks to this study, people around the country can find out what’s in their bodies, and become empowered to reduce their exposures and live healthier lives.

Research supports national movement toward safer food packaging

Explore this work

In a 2017 study, we showed that toxic chemicals called PFASs are commonly found in fast food packaging in the U.S. PFASs (per- and polyfluoroalkyl substances) are grease- and waterproof chemicals found in a wide range of consumer products. Their widespread use in food packaging is concerning because PFASs have been linked with cancers, thyroid disease, immune suppression, low birth weight, and decreased fertility. Following the publication of our research, the state of Washington banned PFASs from all paper food packaging, make it the first state in the country to enact such a law. Several states have since introduced similar legislation.

Landmark publication on mammary carcinogens shapes national research agenda.

Explore this work

In a landmark study published in 2007 in the journal Cancer, researchers at Silent Spring identified 216 chemicals that cause mammary tumors in animals. The findings were based on an analysis of data from national and international sources. The researchers used the information to create a searchable online database called the Mammary Carcinogens Review Database, featuring detailed information on each carcinogen. The publication of this list—the first of its kind—was foundational. It provided a roadmap for studying these chemicals in humans, opened up an entire field of research on the links between environmental chemicals and breast cancer, and helped establish breast cancer prevention as a national research priority.
