Students' toxin research shows public health benefits of citizen science

New research: School-based data collection improves risk awareness and environmental equity

2024-08-21

(Press-News.org) Long-term exposure to arsenic, a hidden danger in many New England drinking water supplies, poses serious health risks, including cancer and cognitive challenges. A groundbreaking citizen science initiative called "All About Arsenic" has emerged in response, empowering students and communities to tackle such health threats head-on.

The benefits are detailed in a peer-reviewed article published today in the journal Environmental Health Perspectives. An accompanying commentary by researchers at Columbia University’s Mailman School of Public Health calls the effort a blueprint for federal investments that can leverage youth engagement to advance “water justice”.

Launched in 2016 by Jane Disney. Ph.D., and her team at MDI Biological Laboratory’s Community Environmental Health Laboratory, the “All About Arsenic" program works with secondary school teachers, students, and scientist partners in Maine and New Hampshire to address drinking water issues related to private water sources.

The initiative turns students into citizen scientists who collect well water samples for analysis of arsenic and other toxic metals. Funded initially with an EPA Environmental Education grant and a National Institute of General Medical Sciences (NIGMS) Science Education Partnership Award (SEPA), the project not only boosts awareness but also drives action to protect public health.

The program grew to include 27 schools over the study period, with students analyzing more than 3,000 water samples. The findings are concerning: 752 (nearly 25% of samples) revealed arsenic levels exceeding five parts per billion, the maximum contaminant level set by New Hampshire. In one extreme case, a sample collected by a Maine student registered a staggering 718 ppb, far above the U.S. standard for municipal water.

"Our research highlighted that many residents are unaware of the risks or haven't tested their water supplies," says Dr. Disney. "By involving students, we not only increase awareness but also empower them to drive policy changes that safeguard their communities."

The program’s impact is multi-faceted, leading to increased water-testing rates, improved data literacy, direct risk mitigation, and more robust toxins databases. In a significant public health victory, students’ testimonies contributed to the passage of legislation in Maine that enables the state housing authority to provide remediation grants for low-income households with contaminated wells.

"The power of citizen science in schools is clear," Disney adds. "Students and teachers can be catalysts for change, driving policy and contributing to improved public health outcomes."

Funded initially with an EPA Environmental Education grant and a National Institute of General Medical Sciences (NIGMS) Science Education Partnership Award (SEPA), the project not only boosts awareness but also drives action to protect public health.

The "All About Arsenic" project continues to grow, with a second NIH SEPA grant funded through the National Institute of Nursing Research, focusing on science communication and intergenerational learning.

Molecular wires with a twist

2024-08-21

Osaka, Japan – From the high-voltage wires that carry electricity over long distances, to the tungsten filaments in our incandescent lights, we may have become accustomed to thinking that electrical conductors are always made of metal. But for decades, scientists have been working on advanced materials based on carbon-based oligomer chains that can also conduct electricity. These include the organic light-emitting devices found in some modern smartphones and computers. In quantum mechanics, electrons are not just point particles with definite ...

Watching your children frolic through a playground is one of the many joys of being a parent or grandparent, but new research has found that engaging in play with kids could help improve mental health. Researchers from the University of South Australia (UniSA) and the University of Canberra (UC) have explored the benefits of intergenerational play through specially designed playgrounds for kids and adults. Intergenerational play brings young children and older people together to engage in enjoyable and creative activities such as storytelling, using playground equipment, and games. The world is facing an ...

The underrated impact of humidity

2024-08-21

Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities. Climate change has measurable impacts on society, including on human mortality. However, current models to assess the health impacts of climate change do not account for every environmental parameter, especially humidity, which could influence heat stress perceived by the human body, leaving room for improvement. For the first time, researchers, including those from the University of Tokyo, successfully incorporated humidity data from hundreds of cities into so-called heat stress indicators ...

Sharing risk to avoid power outages in an era of extreme weather

2024-08-21

In brief Extreme weather is leading to more frequent power grid strain and electricity outages. There are a range of regional cooperation agreements among utilities to share electricity. Expanding cooperation areas in the West could cut outage risks by as much as 40%. Expanding cooperation among electricity providers could also help ensure public opinion and policy remain favorable for renewable energy growth. This summer’s Western heat waves raise the specter of recent years’ rotating power outages and record-breaking electricity demand in the region. ...

Gut bioelectricity provides a path for bad bacteria to cause diseases

2024-08-21

How do bad bacteria find entry points in the body to cause infection? This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where they are vastly outnumbered by good microbes and immune cells. Still, the pathogens navigate to find vulnerable entry points in the gut that would allow them to invade and infect the body. A team of UC Davis Health researchers has discovered a novel bioelectrical mechanism these pathogens use to find these openings. Their study was ...
