Researchers have confirmed that Asian air pollution can travel to the US West Coast under specific meteorological conditions, with pollutants including carbon monoxide and particulates. The study found that air reaches the West Coast in about seven days, but can take as few as four or 10 days, depending on weather patterns.
New Swedish research reveals that even small doses of environmental pollutants can cause lifelong neurological disturbances in laboratory animals. The study also raises concerns about the impact on human babies, highlighting the need for continued vigilance in monitoring these toxic substances.
Studies have shown that low doses of dioxin can cause spontaneous abortions, changes in the immune system, and developmental issues in animals. Fish are also being studied as models for understanding dioxin toxicity, with high levels of toxic pollutants found in northern environments, affecting polar bears, porpoises, and other species.
Scientists have discovered a species of glowing bacteria that can detect pollutants in the deep sea. When exposed to various toxic substances, Photobacterium phosphoreum HE-1a glows up to 50% less brightly, triggering an alarm call that alerts nearby sensors to take action.
A new study reveals that Asian industrial smog is affecting the US West Coast, with 10% of ozone and pollutants coming from East Asia. The University of Washington's research station detected higher levels of pollutants such as nitrogen oxide, carbon monoxide, and ozone, which are likely to be lower in Asia just 30 years ago.
A newly isolated bacterium, coccoid Strain 195, reduces toxic tetrachloroethene and trichloroethene to nontoxic ethene gas. The Cornell researchers' discovery will lead to better pollution cleanup strategies in the field.
A new study shows that nearly half of rural eastern US sites would not meet the new ozone standard, posing health risks to residents. The researchers argue that a regional approach is needed to address rural air pollution, requiring cooperation among states and communities.
Researchers at the University of Cincinnati present success stories in bioremediation and risk assessment, including bacteria strains capable of breaking down toxic compounds like N-heterocyclics and PAHs. A team develops ultra-trace methods to detect metal pollutants, improving accurate risk assessment.
Researchers at the University of Georgia have developed a new test for detecting DNA strand breakage in freshwater mussels, which can serve as an early warning system for pollution. The study found significant strand breakage in mussels exposed to lead, but no damage after long-term exposure.
