“Explosive growth’ in petrochemical production linked to increases in cancers and other diseases in new report

By Carey Gillam

Chemical pollution tied to fossil fuel operations is not only driving harmful climate change but is also posing dire risks to human health at levels that require aggressive private and public efforts to limit exposures, warns a new analysis published in the New England Journal of Medicine on Wednesday.

The article authored by Tracey Woodruff, a professor at the University of California San Francisco (UCSF), cites data from dozens of research studies highlighting what Woodruff calls a nexus between “explosive growth” in the petrochemical industry that includes forecasts for plastic production to grow almost three-fold by 2050, and data showing increases in cancers and other diseases in young people, particularly reproductive cancers in women.

Between 1990 and 2019, rates of neurodevelopmental disorders, diabetes, chronic respiratory disease, and certain cancers are among the non-communicable diseases that have increased, with petrochemicals used in producing plastics and other products among drivers of the growth, according to the paper.

“Numerous medical societies, government agencies, and systematic reviews have concluded that exposure to chemicals and pollution… is an important risk factor for multiple diseases and health inequities and probably contributes to these increases,” the report notes, adding that increases in disease and petrochemical production at the same time “alone cannot be interpreted as causal.”

Doctors and patients need to acknowledge and address the risks, and work to reduce exposures, while regulators need to strengthen chemical evaluations and oversight, said Woodruff, who directs the UCSF Program on Reproductive Health and the Environment and the Environmental Research and Translation for Health (EaRTH) Center.

“This is really important… one of the major factors driving climate change is also increasing our exposures to chemicals that are adversely impacting health,” she said. “Typically people say cancer is a disease of the aging, but now we’re seeing it increasing in people under 50.”

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.
