People with microplastics or nanoplastics in their carotid artery tissues were twice as likely to have a heart attack, stroke or die from any cause over the next three years than people who had none, a new study found…“To date, our study is the first that associated the plastic contamination with human diseases,” said Raffaele Marfella, lead author of the study published Wednesday in the New England Journal of Medicine…

Scientists express concern over health impacts, with another study finding particles in arteries…The scientists analysed 62 placental tissue samples and found the most common plastic detected was polyethylene, which is used to make plastic bags and bottles. A second study revealed microplastics in all 17 human arteries tested and suggested the particles may be linked to clogging of the blood vessels…

It’s not just toxic chemicals. Radioactive waste was also dumped off Los Angeles coast – the Los Angeles Times

For decades, a graveyard of corroding barrels has littered the seafloor just off the coast of Los Angeles. It was out of sight, out of mind — a not-so-secret secret that haunted the marine environment until a team of researchers came across them with an advanced underwater camera…Startling amounts of DDT near the barrels pointed to a little-known history of toxic pollution…but federal regulators recently determined that the manufacturer had not bothered with barrels. (Its acid waste was poured straight into the ocean instead.)…

California’s war on plastic bag use seems to have backfired. Lawmakers are trying again – the Los Angeles Times

Plastic Bags (by wastebusters CC BY-NC-ND 2.0 DEED via Flickr).

According to a report by the consumer advocacy group CALPIRG, 157,385 tons of plastic bag waste was discarded in California the year the law was passed. By 2022, however, the tonnage of discarded plastic bags had skyrocketed to 231,072 — a 47% jump…The problem, it turns out, was a section of the law that allowed grocery stores and large retailers to provide thicker, heavier-weight plastic bags to customers for the price of a dime….

Fire Blanketed Lahaina in Toxic Debris. Where Can They Put It? – the New York Times

Search and Rescue Soldiers and Airmen attached to Hawaii National Guard's Chemical, Biological, Radiological, Nuclear, and high-yield Explosive (CBRNE) Enhanced Response Force Package (CERFP) unit assisted Maui County and State officials in the search and recovery efforts of Lahaina, August 10, 2023.

Crews are sending thousands of truckloads of debris to a temporary disposal site (in Olowalu)..The coast of Olowalu is popular with snorkelers and filled with abundant sea life. In 2017, the coral reef offshore became a focal point for protection by the nonprofit Mission Blue, which advocates to protect the ocean. The organization said the reef acts as a sort of nursery to enhance reefs on other islands nearby. It also supports a large population of manta rays. “It’s environmentally precious,” said Tom Gruber, an adviser to Mission Blue. “It’s like Yosemite. You wouldn’t put a toxic waste dump upstream of Yosemite…”
