Dioxin
Dioxin is the popular name for the family of chlorinated organic compounds comprising of Polychlorinated Dibenzo Furans (PCDF) and Polychlorinated Dibenzo Dioxins (PCDD). PCDD/F's have been shown to bioaccumulate in humans and wildlife. Dioxins and other Persistent Organic Pollutants (POPs) are subject to the Stockholm Convention. The treaty obliges signatories to take measures to eliminate where possible, and minimize where not possible to eliminate, all sources of dioxin.

Sep. 1, 2025 — A new study projects that the Atlantic Meridional Overturning Circulation (AMOC)—the system of currents that includes the Gulf Stream—could shut down after 2100 under high-emission scenarios. This shutdown would drastically reduce heat transport ...
Sep. 1, 2025 — Sargassum has escaped the Sargasso Sea and exploded across the Atlantic, forming the massive Great Atlantic Sargassum Belt. Fueled by nutrient runoff, Amazon outflows, and climate events, these blooms now reshape ecosystems, economies, and ...
Aug. 31, 2025 — A massive global study uncovered a striking paradox: even as total burned land has dropped by more than a quarter since 2002, human exposure to wildfires has skyrocketed. Africa accounts for a ...
Aug. 31, 2025 — Stanford researchers reveal meandering rivers existed long before plants, overturning textbook geology. Their findings suggest carbon-rich floodplains shaped climate for billions of ...
Aug. 31, 2025 — As the Great Salt Lake shrinks, scientists are uncovering mysterious groundwater-fed oases hidden beneath its drying lakebed. Reed-covered mounds and strange surface disturbances hint at a vast ...
Aug. 28, 2025 — In just one afternoon, scientists used a nanoparticle “megalibrary” to find a catalyst that matches or exceeds iridium’s performance in hydrogen fuel production, at a fraction of the ...
Aug. 27, 2025 — Ancient forests may have fueled a deep-sea oxygen boost nearly 390 million years ago, unlocking evolutionary opportunities for jawed fish and larger marine animals. New isotopic evidence shows that this permanent oxygenation marked a turning point ...
Aug. 27, 2025 — Even sharks’ famous tooth-regrowing ability may not save them from ocean acidification. Researchers found that future acidic waters cause shark teeth to corrode, crack, and weaken, threatening their effectiveness as hunting weapons and ...
Aug. 26, 2025 — A research team created a plant-inspired molecule that can store four charges using sunlight, a key step toward artificial photosynthesis. Unlike past attempts, it works with dimmer light, edging closer to real-world solar fuel ...
Aug. 25, 2025 — Researchers uncovered that the Maui wildfires caused a spike in deaths far higher than reported, with hidden fatalities linked to fire, smoke, and lack of medical access. They warn that prevention rooted in Native Hawaiian ecological knowledge is ...
Aug. 23, 2025 — A new study reveals that the majority of Earth’s species stem from a few evolutionary explosions, where new traits or habitats sparked rapid diversification. From flowers to birds, these bursts explain most of the planet’s ...
Aug. 22, 2025 — As the ozone layer recovers, it’s also intensifying global warming. Researchers predict that by 2050, ozone will rank just behind carbon dioxide as a driver of heating, offsetting many of the benefits from banning ...
