Eighth graders in Raleigh take on PFAS

A group a ten middle school students, from the Exploris School in downtown Raleigh, NC, have taken on the challenge to study the presence of PFAS in water and raise awareness in their community on the substance’s health impacts. The Exploris School and students are working in participation with the Design for Change program, a global nonprofit that encourages students to examine some the worlds most challenging social issues. The students are currently in the brainstorming phase of their project, where they will discuss potential solutions to decrease water testing time to more efficiently identify the presence of PFAS contaminated sources.

Changing the Traditional Understanding of How Chemicals Affect Our Health

The way scientists think about how chemicals cause their toxic effects is changing. Recent scientific research tells us that the traditional notion of how chemicals act is being replaced by a better understanding of the actual features of exposures to environmental chemicals. These features include the timing and vulnerability of exposures, exposures to mixtures, effects at low doses and genetic alterations called epigenetics.
Traditional thinking tells us that how much of a chemical you are exposed to (the dose) determines the effect. This principle assumes that chemicals act by overwhelming the body’s defenses at high doses. We’re learning now that this principle is not always accurate and its place in evaluating risks needs to be reconsidered. What we now know is that some chemicals cause their adverse effects at low exposure levels that are not predicted by classic toxicology.
Recent research has shown that environmental chemicals like dioxin or bisphenol A can alter genetic make-up, dramatically in some cases.  These changes are so powerful that they can alter the genetic material in eggs and sperm and pass along new traits in a single generation, essentially by-passing evolution.
It wasn’t too long ago that scientists believed that the DNA in our cells was set for life, that our genes would be passed on from one generation to the next, and that it would take generations to change our genetic makeup. That’s no longer the case.
This new field – called epigenetics – is perhaps the fastest growing field in toxicology and it’s changing the way we think about chemical exposures and the risks they pose. Epigenetics is the study of changes in DNA expression (the process of converting the instructions in DNA into a final product, such as blue eyes or brown hair) that are independent of the DNA sequence itself.
What researchers are learning is that the “packaging” of the DNA is just as important as a person’s genetic make-up in determining a person’s observable traits, such as blue eyes, or their susceptibility to diseases such as adult on-set diabetes, or to the development of lupus.
The environment is a critical factor in the control of these packaging processes. We may be born with our genes, but epigenetics changes occur because of environmental influences during development and throughout life. These influences include chemicals in the food we eat, the air we breathe, the water we drink, and they appear to contribute to the development of cancer and other diseases.
Epigenetics may explain certain scientific mysteries, such as why certain people develop diseases and others don’t, or why the person who smoked for 30 years never developed lung cancer. There is still much to learn, but an early lesson to take away from this emerging science is that we need to rethink our traditional ideas of how chemicals affect our health.

Global Youth Climate Strike

This September, millions of people across the world will walk out of their jobs, classrooms and homes to join in the annual Global Youth Climate Strike. On Friday, September 20 and 27, participants in more than 150 countries will disrupt their daily routines to speak out against the coal, oil, and gas industry with a goal to demand an end to the use of fossil fuels. More information on how to organize a climate strike and strike event locations can be found on the Global Climate Strike website. <Read More>

Members of Seneca Nation paddle 290 miles for peace down Ohi:yo’ (Allegheny) River, Pennsylvania

Members of the Seneca Nation paddled down the entire 290 miles of the Allegheny River, called Ohi:yo’ (meaning beautiful river) in the Seneca language, in a journey called Paddle for Peace to Protect Our Waters. The journey has been organized by Seneca cause Defend Ohi:yo’, a group that helped stop corporations from dumping treated fracking water in the river just last year. The purpose of the journey is to raise awareness about the importance of protecting the environment and to protest a proposed pipeline project that will threaten the region’s rivers. <Read more>

PFAS Chemicals: Failing to Protect the American People

Last week the EPA announced its “Action Plan” for a group of chemicals referred to as per- and polyfluoroalkyl substances or PFAS chemicals. In its news release, the agency described this effort as “historic” and as the “most comprehensive cross-agency plan to address an emerging chemical of concern ever undertaken by EPA.” However, environmental advocates and people who live in communities contaminated by PFAS chemicals were not impressed by the agency’s plan. Group after group released news statements blasting the plan as inadequate and lacking action, lamenting the agency’s failure to create a standard to regulate PFAS chemicals in drinking water.
In response to questions from reporters, EPA expressed the need to set a standard that would be defensible in court and promised that the agency will develop a standard “according to where the science directs us.” While this might make a good sound bite, it falls far short of what environmental advocates and people who live in communities contaminated by PFAS chemicals had hoped for.
The National PFAS Contamination Coalition, a network of communities impacted by PFAS contamination described the agency’s plan as “woefully inadequate for those who have been suffering from exposure to contamination for decades” and that “it fails to prevent current and future exposure to PFAS in the environment.”
The EPA’s failure to set a health standard for PFAS chemicals is nothing new for the agency. They have not issued a new standard for drinking water in over 22 years since the Safe Drinking Water Act was passed in 1996. Andrew Wheeler, Acting Administrator of EPA, described setting a standard for PFAS chemicals as “charting new territory” at the agency’s press conference. Really? Has it been so long that the agency no longer recalls what it needs to do to issue a new standard?
Not having a health standard is huge. Without a standard, there is no clear legal handle that the agency can use to force a polluter to clean up contaminated water to the standard or to require that a water company to provide water that does not have PFAS at the level of the standard. With only a health advisory, the agency has no standing to force a polluter to take the necessary steps to clean up contaminated water or require a water company to provide water that does not have PFAS at the level of the advisory. They can ask. They can recommend. But that cannot require. At least not legally.
More study and analysis as called for in the EPA “Action” plan, will not change this scenario. The agency needs to stop stalling, recall its roots and issue a health standard for PFAS chemicals. The communities that have been contaminated by PFAS chemicals and the American people deserve nothing less.

Would Dr. King have been concerned about climate change?

The answer is resoundingly “yes.” There are clues in his writing and speeches that suggest that would he have been very concerned. A common misperception about Dr. King is that he fought for a specific group of people. Dr. King, like most great humanitarians, fought for anyone facing injustice. He likely would have been an activist for the planet once he saw who was most vulnerable. Read more.
