Research highlights microplastics risks in bottled water

A new study warns that single-use plastic water bottles release nano- and microplastics that pose chronic health risks. Led by Sarah Sajedi at Concordia University, the research estimates bottled water drinkers ingest up to 90,000 more particles annually than tap water users. These tiny pollutants can enter the bloodstream and affect vital organs, leading to inflammation and other issues.

Deep-sea mining poses new threat to sharks and rays

5. Oktober 2025 Von KI berichtet

A new study warns that proposed deep-sea mining could endanger 30 species of sharks, rays, and chimaeras whose habitats overlap with mining zones. Nearly two-thirds of these species are already threatened with extinction from human impacts. Researchers from the University of Hawai'i at Mānoa highlight risks from seafloor disruptions and sediment plumes.

El Paso residents probe warehouse ethylene oxide emissions

A Grist investigation has revealed that emissions of the carcinogen ethylene oxide from Cardinal Health warehouses in El Paso may exceed safe limits, raising cancer risks for much of the city's population. Former worker Maria, diagnosed with aggressive breast cancer years after her time at the facility, now suspects a link. Nearby residents report headaches, dizziness, and respiratory issues amid limited federal oversight.

European institutions launch campaign for International Coccolithophore Day

Five European research institutions have announced an initiative to establish October 10 as International Coccolithophore Day, highlighting the crucial role of these microscopic plankton in regulating Earth's climate. Coccolithophores, tiny algae smaller than dust grains, capture carbon dioxide, produce oxygen, and form geological records of climate history. The campaign aims to raise awareness of their impact on ocean ecosystems amid climate change threats.

Study links extreme heat to workplace injuries as OSHA faces delays

A new study reveals that extreme heat contributes to thousands of workplace injuries annually, with risks rising above 85 degrees Fahrenheit heat index. Researchers confirm that basic protections like water, shade, and breaks reduce these risks. However, a federal government shutdown threatens to delay OSHA's proposed national heat standard.

EPA plans to end greenhouse gas emissions reporting program

5. Oktober 2025 Von KI berichtet

The U.S. Environmental Protection Agency has proposed eliminating its Greenhouse Gas Reporting Program, which requires large emitters to report emissions data. This move, part of broader rollbacks under the Trump administration, raises concerns about tracking national emissions and forming climate policy. Climate experts and NGOs warn that while alternatives exist, they cannot fully replace the federal system's role.

Earth911 updates zero-waste lifestyle guide in 2025

Earth911 has substantially updated its guide on adopting a zero-waste lifestyle, highlighting practical steps to reduce trash amid growing global waste challenges. The article, originally published in 2016, stresses the shift from a linear to a circular economy to minimize environmental impact.

Marine heat waves clog ocean's carbon sequestration mechanism

Two major marine heat waves in the northeastern Pacific have disrupted the ocean's natural process of sinking carbon to the seafloor via zooplankton fecal pellets. A new study reveals shifts in phytoplankton and zooplankton communities that reduced carbon export during these events. This malfunction could impair the ocean's ability to absorb a quarter of human CO2 emissions.

Fossil fish rewrites otophysan evolution history

A tiny fossil fish discovered in southwestern Alberta is the oldest North American otophysan, offering new insights into the evolution of freshwater fish species. Named Acronichthys maccognoi, the 4 cm specimen from the Late Cretaceous period suggests otophysans transitioned from marine to freshwater environments at least twice. The find, detailed in a study published on October 2 in Science, challenges previous understandings of their global spread.
