  • Extramural Paper of the Month: Interaction of Toxic Metals in the Digestive System Revealed
    Paper of the Month - June 2024
    Scientists at the University of Arizona SRP Center examined the effects of arsenic, cadmium, ferrihydrite, and pepsin, an enzyme responsible for protein digestion. Scientists used a simulated gastrointestinal (GI) tract to measure bioaccessibility, or the amount of toxic metals that could be released during digestion and absorbed into the blood stream.
  • Building trust, sharing data: grantee promotes participatory research
    Environmental Factor - March 2022
    During her Feb. 14 NIEHS Keystone Science Lecture, Monica Ramirez-Andreotta, Ph.D., shared the numerous ways she works with communities to integrate their priorities into environmental health sciences research. The University of Arizona SRP Center researcher directs Gardenroots and Project Harvest, which are citizen science initiatives that engage community members about the health of their soil, water, and plants.
  • Engaging Communities to Improve Well-being
    SRP News Page - February 2022
    Monica Ramirez-Andreotta, Ph.D., from the University of Arizona SRP Center, shared her experience engaging communities in science and her journey from SRP trainee to SRP researcher.
  • Plant leaves work as reliable air monitor in citizen-science study
    Paper of the Month - January 2022
    Working with citizen-scientists, NIEHS-funded researchers demonstrated that leaves can be used as a low-cost, reliable method to assess the level of metals in airborne dust. The method can help assess exposure from former mine sites that emit heavy metals that can be distributed by wind to nearby communities.
  • Helping Communities Monitor Air Pollution Using Plants
    Research Brief - October 2021
    An NIEHS Superfund Research Program (SRP)-funded study revealed that certain plants can be used to effectively monitor metals and other pollutants in air. Community members collected environmental data used in the study as part of the Gardenroots project, which involves residents in research activities to evaluate human and environmental health effects near former and operating mining sites in Arizona. The study was led by University of Arizona SRP Center researcher Monica Ramirez-Andreotta, Ph.D.
  • Scientific art competition showcases trainees' research, imagination
    Environmental Factor - September 2021
    When the COVID-19 pandemic forced university laboratories to shut down or go remote, the NIEHS Superfund Research Program (SRP) created an opportunity for trainees to celebrate their research efforts and the stories behind them. Led by SRP Health Scientist Administrator Danielle Carlin, Ph.D., SRP hosted a scientific art competition for trainees.
  • Better risk communication can reduce harmful exposures, experts say
    Environmental Factor - July 2021
    NIEHS grantees, partners, and colleagues came together to discuss how they have engaged with local groups and communicated potential health risks to reduce exposures and improve health. Hosted by the NIEHS Superfund Research Program (SRP) June 21-22, the online workshop drew more than 200 participants.
  • Oral histories shed light on exposures near Superfund sites
    Environmental Factor - March 2020
    A new collection of oral histories from people who work and live near two Arizona Superfund sites was posted online in January. The community-driven Voices Unheard project captures video accounts, photos, and descriptions from communities near the Tucson International Airport Area and the Iron King Mine-Humboldt Smelter Superfund sites.
