Certain common chemicals associated with higher odds of cancer in women

By Carey Gillam

Women exposed to several widely used chemicals appear to face increased odds for ovarian and other certain types of cancers, including a doubling of odds for melanoma, according to new research funded by the US government.

Using data collected by the Centers for Disease Control and Prevention (CDC), a team of academic researchers found evidence that women diagnosed with some “hormonally-driven” cancers had exposures to certain per- and polyfluoroalkyl substances (PFAS), which are used in thousands of household and industrial products, including in stain- and heat-resistant items.

They found similar links between women diagnosed with cancer and high exposures to phenols, which are commonly used in food packaging, dyes and personal care products.

The study, published late Sunday in the Journal of Exposure Science and Environmental Epidemiology, did not find similar associations between the chemicals and cancer diagnoses in men.

PFAS chemicals, in particular, may disrupt hormone functions specific to women – a potential mechanism for increasing their odds of hormone-related cancers, the researchers determined. Hormonally active cancers are common and hard to cure, making deeper inquiry into potential environmental causes critical, the researchers said.

“People should care about this because we know that there is widespread human exposure to these chemicals and we have documented data on that,” said Max Aung, assistant professor of environmental health at USC Kreck School of Medicine and a senior author of the study.

“These chemicals can increase the risk of various different health outcomes and they can alter your biological pathways… that is important to know so that we can better prevent exposures and mitigate risks,” Aung said.

Could farm fertilizers be driving Corn Belt cancers?

By Keith Schneider

BERNE, Minn. – It was a hot afternoon in mid-July and 60-year-old Brian Bennerotte was making a pilgrimage of sorts, navigating a shotgun-straight, gravel road south of Minneapolis on a journey through a landscape stitched with crop and livestock farms as far as the eye can see.

Bennerotte is one of only three surviving members of a family who farmed for three generations along a mile-long stretch of County Road B. As a long-haul truck driver, Bennerotte rarely gets back here. But with a visitor at his side, he finds his way.

From the passenger seat of a rented vehicle he scans both sides of the road, then points to a dust-scoured barn leaning into the wind. The building is all that remains of his family’s farmstead, which once encompassed 200 acres and a home large enough for Bennerotte’s parents to raise five boys and a girl.

Down the road a bit further, he recognizes neighboring properties: There is the Glarner farm, and the Spreiter farm and the Serie farm. All are connected by circumstances of geography, topography, agriculture, and social commerce.

All are also joined by disease and death.

Among the four families who lived for decades along County Road B, 12 people developed cancer and seven died. Bennerotte was one of three people who developed lymphoma. The disease nearly killed him in 1983 when he was 20 years old. His father and three brothers would not survive their own bouts with cancer.

For some, County Road B has a different name: They call it Cancer Road.

“Every family along here was affected. Every one,” said Bennerotte.

An old battle over fur farming heats up with new environmental twist

By Shannon Kelleher

Wearing fur has long been a controversial choice in the United States, with a large roster of fashion brands embracing bans on fur garments on the grounds that the practice is cruel to the animals farmed for their pelts. But a new twist on the issue has been gaining momentum and spurring debate over the impacts of mink farming on human and environmental health.

Earlier this year, California implemented the first state ban on the sale and manufacturing of fur products, including coats, trim on hooded jackets, and pompoms for hats and gloves. Many US cities and towns have banned fur sales, and in June, US Rep Adriano Espaillat, a Democrat from New York, introduced a bill that that would pay mink farmers to shutter their operations and create a nationwide ban on farming the small animals whose silky, sleek coats are coveted for use in high-end attire.

The aim of the federal bill is to reduce the chances that mink farming could trigger outbreaks of viruses that harm humans, an issue that triggered international concerns during the Covid-19 pandemic. Proponents of the measure say they hope it will be included in the upcoming Farm Bill.

Fur farming has also become a subject of intense debate over its environmental impact, with opponents arguing its practices contribute to water pollution and harmful climate change.

Fur farming takes “a huge toll on the environment as well as animals and public health,” said PJ Smith, director of fashion policy for the Humane Society of the United States.

Air pollution can raise risk of Covid-19 death 51%, study says

By Pam Strayer

People who are live in areas that come with long-term exposure to high levels of air pollution face a 50% higher chance of dying from Covid-19, and thousands of lives could have been saved during the pandemic if air quality standards were met, a new public health research study has found.

The study, which focused on California residents, is the latest of several exploring the impacts of air pollution on the incidence and severity of Covid-19 infections. And the research adds to a growing body of global research highlighting the importance of reducing air pollution.

The researchers determined that 9%, or at least 4,250 Covid-19 deaths could have been prevented if California met national air quality standards.

The most vulnerable people in terms of air pollution exposure were likely to be Latinos and those living in low-income areas, the researchers found.

The study, published in Environmental Advances, was authored by Paul English, director of the Public Health Institute and its “Tracking California” program, along with ten other researchers, including some affiliated with the University of California San Francisco (UCSF) department of medicine and the UCSF department of epidemiology and biostatistics.

“People of color live in communities that have some of the worst air pollution and also have greater chances of getting sick and even greater chances of dying from COVID,” English said in a release announcing the study.
