Scientists will analyze air and aerosol pollutants using aircraft, ground stations, and satellite observations. The goal is to understand the impact of urban pollution on regional and global climate, ecosystems, and visibility.
A new study shows that the net benefits of eating wild Pacific salmon outweigh those of eating farmed Atlantic salmon when considering chemical contaminants. Regional differences in contaminant levels make some farmed salmon safer choices than others.
A study found that exposure to persistent organochlorine pollutants like CB-153 and DDE is significantly associated with a high prevalence of type 2 diabetes among fishermen and their wives. The results show that those with higher blood levels of these pollutants have a higher risk of developing the disease.
Researchers at Carnegie Mellon University have discovered a green catalyst, Fe-TAML, that can efficiently destroy nitrophenol pollutants. The catalyst works with hydrogen peroxide and has shown promise in killing biological warfare agents, reducing fuel pollutants, and detoxifying pesticides.
A study by Canadian scientists found high levels of pollutant films on windows in lower Manhattan six weeks after the 9/11 attacks, revealing concentrations up to 10 times greater than normal background levels. The findings suggest that urban areas like New York City have high levels of toxic organic pollutants.
Researchers found that pollutants like lindane and hexachlorobenzene (HCB) behave differently in the presence of organic matter and sunlight, with HCB degrading at higher rates. The study suggests that pollutants can have varying effects on local ecosystems and human health.
Researchers found that every slice of toothed whale red meat exceeded Japan's mercury limit, with some samples containing almost 200 times the maximum value. Mercury levels were higher in whales caught off the southern coast of Japan.
A new instrument, PILS, automates aerosol sampling and provides more detailed time-dependent information on atmospheric pollutants. This allows scientists to make frequent measurements, revealing previously unknown morning and afternoon peaks in pollutant levels.
Research found that men exposed to polychlorinated biphenyls (PCBs) before age 20 had a lower chance of having a baby boy, with a 35% difference. The study's lead author proposes that dioxin-like compounds may negatively impact the viability of Y-chromosome carrying sperm or XY-fertilised eggs.
A study by Cornell University researchers found that low-income households and child-care facilities in New York state have high levels of air pollutants, including radon, lead, and mold. These pollutants can lead to serious health issues such as lead poisoning, asthma attacks, and allergies.
A virtual lung model developed at PNNL may help predict pollutant impact on respiratory systems, providing new insights into asthma and other pulmonary diseases. The model simulates how pollutants enter, travel through, and collect in the lungs, enabling scientists to design targeted treatments.
A Kenyan study found a significant link between exposure to particulate matter (PM10) from biomass fuels and acute respiratory infections. The researchers estimated the public health benefits of reduced PM10 exposure, with the greatest impact seen for average exposures below 1000-2000 mg/m3.
