Wildfire smoke is now linked to worsening eczema symptoms
Researchers have found that exposure to wildfire smoke can worsen eczema, adding to growing evidence of how air pollution harms skin health.
In short:
- A study led by Dr. Raj Fadadu and Dr. Maria Wei revealed a link between wildfire smoke and eczema, a common skin condition.
- Even short-term exposure to polluted air can aggravate symptoms like itchiness and dryness in people with eczema.
- As wildfires increase due to climate change, these findings suggest worsening skin health impacts.
Key quote:
"I feel like as climate change has progressed throughout my youth and adulthood, I'm seeing how a lot of the damage is done to the environment or harming human health — and one of the ways that's happening is through the generation of air pollution."
— Raj Fadadu, dermatologist at the University of San Francisco
Why this matters:
As wildfires grow more frequent, more people may suffer from aggravated skin conditions like eczema. Understanding these effects could lead to better treatment and policy responses.

Wildfires in Canada bring health concerns with persistent smoke exposure
Increased frequency and intensity of wildfires in Canada pose significant long-term health risks due to persistent smoke exposure.
Stephanie Cleland and Ryan W. Allen write for The Conversation.
In short:
- Wildfires in Canada have increased by 220% over the last two decades, threatening air quality.
- Long-term exposure to wildfire smoke is linked to premature death, reduced lung function and increased cancer risks.
- Persistent smoke exposure also affects cognitive function and prenatal health.
Why this matters:
Chronic exposure to wildfire smoke can lead to a variety of long-term respiratory issues. Conditions such as asthma and chronic obstructive pulmonary disease can be exacerbated, leading to more frequent and severe attacks. Even those without pre-existing conditions can develop new respiratory problems after prolonged exposure to these harmful pollutants. For vulnerable populations like children, the elderly and individuals with pre-existing health conditions, the risks are even higher.

Living near oil and gas operations linked to worse mental health in people hoping to become pregnant
“If we’re concerned about healthy pregnancies, focusing on the period before pregnancy may be even more important.”
Living near oil and gas operations, including fracking wells, is linked to stress and depression in people who are planning pregnancies, according to a new study.
Previous research has found that living near oil and gas operations is linked to physical and mental health problems during and after pregnancy including preterm birth, birth defects, low birth weights and increased stress. However, little research exists on the effects of preconception mental health. Some studies suggest that poor mental health during this time period is associated with increased odds of pregnancy complications.
The new study, conducted by researchers at the Boston University School of Public Health and published in the American Journal of Public Health, is the first to investigate how living near oil and gas operations affects mental health in people who are hoping to become pregnant.
“There are around 29 studies to date on associations between residential proximity to oil and gas development and adverse birth outcomes,” Mary D. Willis, lead author of the study and assistant professor at the Boston University School of Public Health, told EHN. “That body of work is very focused on the long-term health of infants, which is important, but this work adds to that literature by centering the potentially pregnant person.”
Willis and her colleagues looked at mental health survey data for 5,725 people, including residents across 37 U.S. states and Canadian provinces, who were planning to get pregnant. The study only included people with household incomes below $50,000 a year since they may not have the resources to move away from oil and gas operations if they wanted to.
They found that people who lived within roughly six miles of active oil and gas development were more likely to report moderate-to-severe depressive symptoms than people living 12 to 31 miles away, and that higher levels of active oil and gas activity were linked to higher reported levels of depression. They also found that the closer people lived to oil and gas operations, the higher the intensity of their stress levels.
While the study doesn’t prove that oil and gas operations cause stress and depression, researchers point to factors like changing economic and social dynamics and environmental degradation in communities with oil and gas development as factors that could impact mental health.
“Our findings lend credibility to the hypothesis that this industry, with its boom and bust cycles, brings economic, environmental and social hazards that lead to negative mental health outcomes,” Willis said.
“If we’re concerned about healthy pregnancies, focusing on the period before pregnancy may be even more important, and that time-frame is under-studied,” she added.
The study noted that many of the people in the study who reported elevated stress and depression symptoms lived further away from oil and gas operations than the minimum distance required in many states to protect people in homes, schools and healthcare facilities.
“Our findings lend credibility to the hypothesis that this industry, with its boom and bust cycles, brings economic, environmental and social hazards that lead to negative mental health outcomes.” - Mary D. Willis, Boston University
In Pennsylvania and Texas, for example, the two states with the highest rates of natural gas production, minimum “setback” distances are as small as 200 feet. Pennsylvania’s setback has been increased to 500 feet, but that only applies to newly constructed oil and gas wells.
The findings of the study imply that “these setback distances may not be big enough to protect population health and specifically mental health,” Willis said.

Polluted air is endangering newborns in New Mexico
A new study reveals that air pollution is significantly linked to low birth weight among babies born near industrial areas in New Mexico, posing serious health risks.
In short:
- The University of New Mexico study connects exposure to five industrial pollutants with low birth weight in infants.
- Areas like Albuquerque, Santa Fe and the Permian Basin –the country's most productive oilfield– have some of the worst air quality in the U.S., affecting local newborns' health.
- Minority and low-income communities face disproportionate impacts from pollution, with higher incidences of low birth weight among Black and Latino infants.
Key quote:
“The stakes are incredibly high. Low birth weight not only impacts the health of newborns but can also set children up for health issues that extend well into adulthood.”
— Giovanna Rossi, New Mexico organizer for Moms Clean Air Force.
Why this matters:
Protecting pregnant women and their babies from industrial pollution is vital as low birth weight is linked to severe health issues, from respiratory problems to heart disease, creating a critical public health crisis.

Court delays Biden administration's cross-state air pollution plan
The Supreme Court has temporarily halted the EPA's plan to reduce air pollution across state lines, hindering Biden's environmental agenda.
In short:
- The Supreme Court has put a hold on the EPA's "good neighbor" plan, which aimed to cut ozone pollution from Western and Midwestern states affecting Eastern states.
- The ruling was a narrow 5-4 decision, with Justice Gorsuch writing for the majority, stating the stay will remain until a federal appeals court reviews the matter.
- Justice Barrett, dissenting, warned that the decision would allow continued pollution, impacting downwind states' air quality and public health.
Key quote:
“The court’s extraordinary decision today to grant an emergency stay is a travesty of justice that puts the lives and health of millions of people at risk.”
— Vickie Patton, general counsel of the Environmental Defense Fund
Why this matters:
This decision delays efforts to mitigate harmful air pollution, posing risks to public health, particularly for those in downwind states affected by emissions linked to asthma and lung disease.

Congestion pricing pause halts NYC air pollution projects
New York City’s pause on congestion pricing endangers over $100 million in projects aimed at reducing air pollution in low-income neighborhoods.
In short:
- Governor Kathy Hochul paused the congestion pricing program, jeopardizing funding for air quality projects in the Bronx and other areas.
- Planned projects included asthma treatment centers, air filtration systems in schools, and electric charging infrastructure for trucks.
- The move undermines efforts to mitigate higher emissions in vulnerable communities affected by increased truck traffic.
Key quote:
"The money has disappeared, but what will not disappear are the air pollution rates, the asthma rates, the greenhouse gas emissions.”
— Ritchie Torres, U.S. Representative
Why this matters:
Low-income neighborhoods in NYC have long suffered from disproportionate exposure to air pollutants, leading to higher rates of asthma and other respiratory illnesses. The congestion pricing initiative was seen as a crucial step in addressing environmental injustices and promoting public health.
