Building healthier communities through better science

The Environmental Health Sciences Center (EHSC) at UC Davis strives to bridge the gap between science and health. Our mission seems simple enough – to advance a better understanding of disease and disability related to the environment so people can reduce their exposure to chemicals and toxins.

But transforming what we know about the environment into action is more of a challenge. That’s because we believe the work we do in the lab should connect meaningfully with the communities we’re trying to help. It’s a harder road but a more strategic and worthwhile one too.

This is a much different approach than the old stereotype of the scientist hidden away in a lab. But working with communities to solve environmental health problems can lead to innovations and greater rigor in science, too. And this kind of community-based science ensures what we learn transforms into policies that lessen the social burden of environmental health problems, from autism to climate change.

EHSC’s Community Stakeholder Advisory Committee is made up of community groups concerned with water and air quality, environmental justice and pesticide exposure. This community-scientist partnership helps shape the kind of real-world research EHSC supports and funds through dozens of groundbreaking projects. A few examples of these community-based projects include:

  • Investigating the effect water quality has on zebrafish to better understand the impact it has on human reproduction
  • Analyzing the economic cost of pesticide-related intellectual disability
  • Studying the health effects of air pollution near the Salton Sea

EHSC scientists also are doing pioneering work around autism and the environment. Our researchers were first to identify ways in which genes and nutrition change how the environment affects us. They showed many factors are responsible for the development of a disease or condition, and that good nutrition is a potent buffer against the toxic chemicals that can lead to autism.

They also discovered that the environment changes how genes associated with autism express themselves during pregnancy. This glimpse in utero could someday help identify the condition during a critical window of development, forever changing life’s possibilities for a child with autism.

EHSC is uniquely positioned to help with California’s Climate Change Program as the state confronts increased wildfires, drought and heat due to the dramatic shift in the Earth’s temperature. EHSC-led climate projects include:

  • Studying air pollution as the Earth’s temperature rises
  • Surveying survivors of the 2017 Northern California wildfires
  • Researching the impact wildfires have during pregnancy
  • Analyzing ash and debris from urban wildfires
  • Researching how heat injures the kidneys of farmworkers

The environmental change communities need, particularly when they’re disproportionately burdened with environmental exposures, can seem overwhelming at best. But working at the community level around environmental health problems inspires change at the top too, which can quicken our pace toward action.

One such initiative is Project TENDR (Targeting Environmental Neuro-Development Risks), a coalition of environmental scientists, health professionals and children’s and environmental advocacy organizations working together to protect kids from the harm chemicals and other environmental hazards pose. 

Project TENDR’s consensus statement calls on regulators and scientists to upend the way chemicals are assessed, including the failure to establish safety thresholds for many of them. Project TENDR draws together a critical mass to help lead change at the policy level, not least of which is the adoption of its lead recommendations by the American Medical Association.

Individually, these might all seem like small steps but together they move us prodigiously toward a single goal: To leave the Earth a healthier place so future generations can enjoy it and thrive.
