When the research vessel Sally Ride set sail for Santa Catalina Island to map an underwater graveyard of DDT waste barrels, its crew had high hopes of documenting for the first time just how many corroded containers littered the seafloor off the coast of Los Angeles. But as the scientists on deck began interpreting sonar images gathered by two deep-sea robots, they were quickly overwhelmed. It was like trying to count stars in the Milky Way. More:

Seven years ago, a kindergarten teacher at P.S. 290 in Manhattan was following her students’ curiosity about the origins of food when she led them in a role play on how toxic pesticides harm people, ecosystems and even — to the 5-year-olds’ horror — turtles like their class pet, Soccer Ball. More:

As the impact of our species on the natural world intensifies, so does the knowledge of our dependency on it: from crop-pollinating critters and wild fish populations that nourish millions, to ecosystems that inhale carbon emissions and filter air and water.

Paper straws broke down in drinks really quickly. But then the biodegradable market—plant- and paper-based straws—expanded, giving people more structurally sound plastic straw replacement options. People could dip them in a drink without having to pull out a soggy clump of paper. Oftentimes, companies will coat permeable products in per- and polyfluoroalkyl substances (PFAS). More:

Indoor dust contains dangerous, endocrine-disrupting chemicals, according to a study.

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:

A new study by Simon Fraser University's Faculty of Health Sciences researchers found correlations between increased expressions of autistic-like behaviors in pre-school aged children to gestational exposure to select environmental toxicants, including metals, pesticides, polychlorinated biphenyls (PCBs), phthalates, and bisphenol-A (BPA).

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.

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:
