Endocrine-disrupting chemicals found in menstrual products including tampons, pads, and liners 

Endocrine-disrupting chemicals can interfere with human hormones and cause medical issues

2023-12-15
(Press-News.org) The average menstruator will use over 11,000 tampons or sanitary pads in their lifetime. Vaginal and vulvar tissue that touch pads and tampons is highly permeable. Through this permeable tissue chemicals are absorbed without being metabolized, which makes endocrine-disrupting chemicals potentially dangerous when found in menstrual products. Endocrine-disrupting chemicals can interfere with human hormones and cause medical issues, including gynecological conditions such as endometriosis and uterine fibroids. 

Joanna Marroquin, a Mason PhD in Public Health student, and Associate Professor Anna Pollack, reviewed studies conducted since 2103 that measured chemicals in menstrual products and that measured human biomarkers of chemical exposure and determined that endocrine-disrupting chemicals were found in menstrual products including tampons, pads, and liners. 

“Identifying chemicals in menstrual products that menstruators regularly use is important because exposure through these products can impact menstruators’ reproductive health,” said Marroquin, the paper’s first author.  

The study found that menstrual products contain a variety of endocrine-disrupting chemicals including phthalates, volatile organic compounds, parabens, environmental phenols, fragrance chemicals, dioxins and dioxin-like compounds. 

This issue is even more relevant thanks to the Robin Danielson Menstrual Product and Intimate Care Product Safety Act of 2023, which was introduced in the U.S. House of Representatives in October 2023. The Act would establish a program of research regarding the risks posed by the presence of dioxins, phthalates, pesticides, chemical fragrances, and other components in menstrual products and intimate care products. 

This literature reviewed 15 papers published between 2013 and 2023 that tested menstrual products in the U.S., Japan, and South Korea. The researchers note that there are few publications available that measure chemicals in menstrual products.  

Additionally, though forever chemicals (PFAS) have been found in menstrual underwear, there is a lack of peer-reviewed research on menstrual underwear and other newly-popular-in-the-U.S. products such as menstrual cups and discs. 

Chemicals in menstrual products: A systematic review was published in BJOG, an international journal of obstetrics and gynecology in September 2023. Additional authors include Marianthi-Anna Kiomourtzoglou from Mailman School of Public Health, Columbia University and Alexandra Scranton from Women's Voices for the Earth.  

The research was supported by Pollack's National Institute of Environmental Health Sciences R01ES31079 award.

Study shows exposure to household chemicals can lower odds of getting pregnant

Study shows exposure to household chemicals can lower odds of getting pregnant
2023-12-15
Exposure to phthalates, a group of plasticizing and solvent chemicals found in many household products, was linked to a lower probability of getting pregnant, but not to pregnancy loss, according to research by a University of Massachusetts Amherst environmental and reproductive epidemiologist. The study, published this week in the journal Environmental Health Perspectives, also noted an association between preconception exposure to phthalates and changes in women’s reproductive hormones, as well as increased inflammation and oxidative stress.   “Phthalates ...

North America’s first people may have arrived by sea ice highway

2023-12-15
SAN FRANCISCO — One of the hottest debates in archeology is how and when humans first arrived in North America. Archaeologists have traditionally argued that people walked through an ice-free corridor that briefly opened between ice sheets an estimated 13,000 years ago.   But a growing number of archeological and genetic finds — including human footprints in New Mexico dated to around 23,000 years old — suggests that people made their way onto the continent much earlier. These early Americans likely traveled along the Pacific coastline from Beringia, the land bridge between Asia and North America ...

Xinfeng Gao named 2024 AIAA Associate Fellow

We are pleased to announce that the American Institute of Aeronautics and Astronautics (AIAA), a preeminent aerospace professional society, has selected professor Xinfeng Gao to be a member of the class of 2024 AIAA associate fellows. Only one member of the Institute for every 150 members is selected as an associate fellow each year by the review committee. “This recognition illustrates the impact of our outstanding faculty. Aerospace engineering at UVA continues on a great trajectory and professor Gao is a big part of that,” said Richard W. Kent, professor and chair of the Department of Mechanical and Aerospace Engineering. Pioneering ...

Substance-abuse stigma impedes treatment in various ways, scientists say

2023-12-15
Addiction is one of society’s most misunderstood and rebuked health conditions. That stigma discourages many people from seeking treatment for substance dependence, according to a new report published in Psychological Science in the Public Interest, a journal of the Association for Psychological Science.  Research on stigma toward people with substance use disorder (SUD) is relatively sparse, the report adds. “Characterizing the nature and etiology of SUD stigma is critical for developing tailored and effective interventions ...

Ultrafast lasers map electrons 'going ballistic' in graphene, with implications for next-gen electronic devices

2023-12-15
LAWRENCE — Research appearing in ACS Nano, a premier journal on nanoscience and nanotechnology, reveals the ballistic movement of electrons in graphene in real time. The observations, made at the University of Kansas’ Ultrafast Laser Lab, could lead to breakthroughs in governing electrons in semiconductors, fundamental components in most information and energy technology. “Generally, electron movement is interrupted by collisions with other particles in solids,” said lead author Ryan Scott, ...

Revolutionizing forestry: 'CountShoots' unveils advanced UAV and AI techniques for precise slash pine shoot counting

Revolutionizing forestry: CountShoots unveils advanced UAV and AI techniques for precise slash pine shoot counting
2023-12-15
In southern China, the genetically improved slash pine (Pinus elliottii) plays a crucial role in timber and resin production, with new shoot density being a key growth trait. Current manual counting methods are inefficient and inaccurate. Emerging technologies such as UAV-based RGB imaging and deep learning (DL) offer promising solutions. However, DL methods face challenges in global feature capture, necessitating additional mechanisms. Innovations like the Vision Transformer and its derivatives (e.g., TransCrowd, CCTrans) show potential in plant trait counting, offering simplified and more effective approaches for large-scale and accurate ...

UMSOM researchers discover first ever link between hemoglobin-like protein and normal heart development

UMSOM researchers discover first ever link between hemoglobin-like protein and normal heart development
2023-12-15
BALTIMORE, December 14, 2023– In a landmark study led by the University of Maryland School of Medicine, researchers discovered for the first time that a certain kind of protein similar to hemoglobin, called cytoglobin, plays an important role in the development of the heart. Specifically, it affects the correct left-right pattern of the heart and other asymmetric organs. The findings, published today in the journal Nature Communications, could eventually lead to the development of new therapeutic interventions to alter the processes that lead ...
