Indoor dust contains dangerous, endocrine-disrupting chemicals, according to a study. The study of 46 dust samples from 21 buildings at a U.S. university found that all 46 samples contained hormonally active compounds that can lead to health effects, including infertility, diabetes, obesity, abnormal fetal growth, and cancers.

Rainwater collected in the Ohio-Indiana region contains both new and phased-out per- and polyfluoroalkyl substances (PFAS), according to research. Rainwater samples also contained high levels of perfluorooctanoic acid (PFOA), which is no longer made in the US. The continued presence of PFOA is likely explained by its ability to persist in the environment over the long term. They also found high levels of PFOA’s replacement, hexafluoropropylene oxide dimer acid (HFPO-DA). More:

For decades, Europe has poured millions of tons of its trash into incinerators each year, often under the green-sounding label “waste to energy.” Now, concerns about incineration’s outsized carbon footprint and fears it may undermine recycling are prompting European Union officials to ease their long-standing embrace of a technology that once seemed like an appealing way to make waste disappear.

In Connecticut, a condo had lead in its drinking water at levels more than double what the federal government deems acceptable. At a church in North Carolina, the water was contaminated with extremely high levels of potentially toxic PFAS chemicals. The water flowing into a Texas home had both—and concerning amounts of arsenic, too. All three were among locations that had water tested as part of a nine-month investigation into the country’s drinking water. More:

Researchers from Germany, Malaysia, and the United States published the results of a systematic review estimating the number of unintentional pesticide poisonings and fatalities globally. The conclusion was startling: An estimated 44 percent of farmers, farmworkers, and pesticide applicators experience at least one incident of acute pesticide poisoning on the job every year, and 11,000 die annually from accidental pesticide poisoning.

The Michigan Department of Health and Human Services (DHHS) issued a warning after PFAS chemicals were found in rainbow smelt collected in 2019 from Lake Superior near the Apostle Islands. Adults should not eat more than one 8-ounce serving of Lake Superior smelt per month, and children shouldn’t eat more than one 4-ounce serving per month, the state says. More:

Scientists have detected 109 chemicals in a study of pregnant women, including 55 chemicals never before reported in people and 42 "mystery chemicals," whose sources and uses are unknown. The chemicals most likely come from consumer products or other industrial sources. They were found both in the blood of pregnant women, as well as their newborn children, suggesting they are traveling through the mother's placenta. More:

It was a blazing-hot morning in October 2019 on the old Ho Chi Minh Trail, an intricate web of truck roads and secret paths that wove its way across the densely forested and mountainous border between Vietnam and Laos. Susan Hammond, Jacquelyn Chagnon and Niphaphone Sengthong forded a rocky stream along the trail and came to a village of about 400 people called Labeng-Khok, once the site of a logistics base inside Laos used by the North Vietnamese Army to infiltrate troops into the South. In one of the bamboo-and-thatch stilt houses, the ladder to the living quarters was made from metal tubes that formerly held American cluster bombs. More:

A new study has made a significant advance in the field by identifying how environmental information is transmitted by non-DNA molecules in the sperm. It is a discovery that advances scientific understanding of the heredity of paternal life experiences and potentially opens new avenues for studying disease transmission and prevention. More:

The whole spectrum of reproductive problems in males are increasing by about 1 percent per year in Western countries. This “1 percent effect” includes the rates of declining sperm counts, decreasing testosterone levels and increasing rates of testicular cancer, as well as a rise in the prevalence of erectile dysfunction. On the female side of the equation, miscarriage rates are also increasing by about 1 percent per year in the U.S. More:

There’s a looming solution to all of humanity’s problems — by 2045 most men may no longer be able to reproduce because of the impact of hormone-altering chemicals. That's according to Shanna Swan, a leading scholar of reproductive health. Four years ago, she calculated that the sperm count of the average man in Western countries had fallen by 59 percent from 1973 to 2011— making international headlines of a looming “spermageddon.” More:

When Californians learned that the waters off Santa Catalina Island once served as a dumping ground for thousands of barrels of DDT waste, the ocean science community jumped into action. A crew was swiftly assembled, shipping lanes cleared, the gears set in motion for a deep-sea expedition aboard the Sally Ride, one of the most technologically advanced research vessels in the country.

“Count Down,” which Shanna Swan wrote with the health and science journalist Stacey Colino, chronicles rising human infertility and warns of dire consequences for our species if this trend doesn’t slow. The reason, Swan explains, may be growing exposure to “endocrine disrupting chemicals” that are found in everything from plastics, flame retardants, electronics, food packaging and pesticides to personal care products and cosmetics.
