Ecologists from the University of Michigan and the University of Maryland Center for Environmental Science are forecasting a large Chesapeake Bay "dead zone" in 2019 due to well-above-average river flows associated with increased rainfall in the watershed since last fall.
New insights about how to understand and ultimately control the chemistry of ignition behavior and pollutant formation have been discovered in research led by Sandia National Laboratories. The discovery eventually will lead to cleaner, more efficient internal combustion engines.“Our findings will allow the design of new fuels and improved combustion strategies,” said Nils Hansen, Sandia researcher and lead author of the research.
Emissions of methane from the industrial sector have been vastly underestimated, researchers from Cornell University and Environmental Defense Fund have found.
For years, routine testing has shown that watersheds of the Mahaulepu Valley and Waikomo Stream in southeast Kauai frequently contain high counts of potentially pathogenic fecal indicator bacteria (FIB). To better understand the cause of the high FIB counts, the DOH commissioned a study by Berkeley Lab microbial ecologists Gary Andersen and Eric Dubinsky. After using a powerful microbial detection tool called the PhyloChip, the scientists concluded that most of the past monitoring results were false positives.
Commonly used in non-stick and protective coatings, lubricants and aviation fire-fighting foams, PFAS does not break down readily in the environment. Tests by the US FDA has detected PFAS and other "forever chemicals" contamination of food. The new polymer is a breakthrough in absorbing and removing toxic PFAS.

Fewer deaths and serious illnesses have occurred in the U.S. over the past decade as a result of cleaner air, according to a new report focusing on the two most potent air pollutants: fine particle (PM2.5) and ground-level ozone (O3). However, these improvements are almost entirely due to reductions in PM2.5 pollution.
A relatively simple process could help turn the tide of climate change while also turning a healthy profit. That's one of the hopeful visions outlined in a new Stanford-led paper that highlights a seemingly counterintuitive solution: converting one greenhouse gas into another.
Permeable pavements are one of many tools in sustainable urban development. Others include rain gardens, cisterns and green roofs. UF/IFAS encourages designers, builders and governments to use the entire urban sustainability development toolbox, said Eban Bean, an assistant professor of agricultural and biological engineering.
According to the World Health Organization (WHO), seven million people worldwide die as a consequence of air pollution every year.
In a unique experimental setup, Swiss researchers have investigated the effect of exhaust particles from aircraft turbine engines on human lung cells. The cells reacted most strongly to particles emitted during ground idling. The study also showed that the cytotoxic effect is only to some extent comparable to that of particles from gasoline and diesel engines.
An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a Rutgers-led study. The study, in the Journal of Geophysical Research: Atmospheres, will help improve predictions of how the climate will respond to future high-latitude volcanic eruptions.
If you’ve ever wished for a quieter commute, you may be in luck: The low-emission electric vehicles of tomorrow are expected to lower noise pollution as well as air pollution. The prospect of a future powered by environmentally friendly electric vehicles is leading experts to consider the benefits -- and the risks -- of quieter traffic. Two acoustics experts, Klaus Genuit and Rene Weinandy, will present their work studying acoustic vehicle alerting systems, or AVAS, at the 177th ASA Meeting, May 13-17.

Air pollution from diesel engines may worsen allergy-induced lung impairment more when tiny particles are filtered from the exhaust than when they are not, according to new research published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
About 4 million children worldwide develop asthma each year because of inhaling nitrogen dioxide air pollution, according to a study published today by researchers at the George Washington University Milken Institute School of Public Health (Milken Institute SPH). The study, based on data from 2010 to 2015, estimates that 64 percent of these new cases of asthma occur in urban areas. The study is the first to quantify the worldwide burden of new pediatric asthma cases linked to traffic-related nitrogen dioxide by using a method that takes into account high exposures to this pollutant that occur near busy roads.
New research from The Ohio State University has shown that combining natural rubber with bioplastic in a novel way results in a much stronger replacement for plastic, one that is already capturing the interest of companies looking to shrink their environmental footprints.
Antioxidants such as vitamin C could help reduce harmful effects from hexavalent chromium, according to a new study performed with human cells. The contaminant, which is often produced by industrial processes, was featured in the biographical movie Erin Brockovich.
Measurements of hazardous air pollutant concentrations near operational sites have generally failed to capture levels above standard health benchmarks; yet, the majority of studies continue to find poor health outcomes increasing as distance from these operations decreases.

A new method for reconstructing changes in nitrogen sources over time has enabled scientists to connect excess nutrients in the coastal waters of West Maui, Hawaii, to a sewage treatment facility that injects treated wastewater into the ground.
Human-caused pollution spurs the production of climate-changing particles known as secondary organic aerosols much more than previously thought. Researchers made the finding by analyzing air samples that were captured aboard a research aircraft as it zig-zagged between pristine air over the Amazon rainforest and polluted air over the city of Manaus.
Scientists at the Cornell Lab of Ornithology have published new research highlighting artificial light at night as a contributing factor. They've ranked metropolitan areas where, due to a combination of light pollution and geography, birds are at the greatest risk of becoming attracted to and disoriented by lights and crashing into buildings. The research was published today in the journal Frontiers in Ecology and the Environment. It combines satellite data showing light pollution levels with weather radar measuring bird migration density.

When you flush the toilet, you probably don’t think about the traces of the medicine and personal care products in your body that are winding up in sewage treatment plants, streams, rivers, lakes, bays and the ocean. But Rutgers scientists have found that bacteria in sewage treatment plants may be creating new contaminants that have not been evaluated for potential risks and may affect aquatic environments, according to a study in Environmental Toxicology and Chemistry.
We all know that turning off lights and buying energy-efficient appliances affects our financial bottom line. Now, according to a new study by University of Wisconsin–Madison researchers, we know that saving energy also saves lives and even more money for consumers by alleviating the costs of adverse health effects attributed to air pollution.
