Many people live in subdivisions with storm water ponds, which collect water from the neighborhood and help keep pollutants such as fertilizers, pesticides and pet waste from getting into the broader environment. Now, UF/IFAS researchers and Extension faculty have devised strategies to help homeowners limit their pollution contribution.
Today, the Environmental Protection Agency announced a lower National Ambient Air Quality Standard for ozone of 70 parts per billion (ppb)/8-hours daily maximum concentration. While today’s announcement represents progress towards improving our nation’s air quality and the overall health of the American public, the selection of 70 ppb ignores the compelling evidence that a more protective standard is needed.

A research team led by Kezhong Zhang, Ph.D., at the Wayne State University School of Medicine’s Center for Molecular Medicine and Genetics, has discovered that exposure to air pollution has a direct adverse health effect on the liver and causes liver fibrosis, an illness associated with metabolic disease and liver cancer.
A new study of more than 300 women suggests that exposure to certain phthalates — substances commonly used in food packaging, personal-care and other everyday products — could be associated with miscarriage, mostly between 5 and 13 weeks of pregnancy.
By combining information about power plant operation with real-time air quality predictions, researchers have created a new capability to minimize the human health effects of air pollution resulting from electric power generating facilities.
Highly efficient, light-emitting diodes (LEDs) could slash the world’s electricity consumption. They are already sold in stores, but are expensive, and many of them give off “harsh” light. But researchers will report today that they have developed a less expensive, more sustainable white LED with a warm glow. The scientists will discuss their research at the 250th National Meeting & Exposition of the American Chemical Society.
Finding a technology to shift carbon dioxide (CO2), the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream. Now, a team of chemists says they have developed a technology to economically convert atmospheric CO2 directly into highly valued carbon nanofibers for industrial and consumer products. They will present the research at the 250th National Meeting & Exposition of the American Chemical Society.
In a first-of-its-kind study, researchers have determined that natural sunlight triggers the release of smog-forming nitrogen oxide compounds from the grime that typically coats buildings, statues and other outdoor surfaces in urban areas. The finding confirms previous laboratory work using simulated sunlight and upends the long-held notion that nitrates in urban grime are “locked” in place. The scientists will present their findings at the 250th National Meeting & Exposition of the American Chemical Society.
Human consumption of bacterially contaminated water causes millions of deaths each year throughout the world—primarily among children. A researcher at the 250th National Meeting & Exposition of the American Chemical Society today will discuss an inexpensive, simple and easily transportable nanotechnology-based method to purify drinking water. She calls it The Drinkable BookTM, and each page is impregnated with bacteria-killing metal nanoparticles.

Using a climate model that can tag sources of soot and track where it lands, researchers have determined which areas around the Tibetan Plateau contribute the most soot -- and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes. The study, which appeared in Atmospheric Chemistry and Physics in June, might help policy makers target pollution reduction efforts.

A University of Michigan researcher and his colleagues are forecasting a slightly below-average but still significant "dead zone" this summer in the Chesapeake Bay, the nation's largest estuary.
Improving air quality — in clean and dirty places — could potentially avoid millions of pollution-related deaths each year. That finding comes from a team of environmental engineering and public health researchers who developed a global model of how changes in outdoor air pollution could lead to changes in the rates of health problems such as heart attack, stroke and lung cancer. The researchers were surprised to find the importance of cleaning air not just in the dirtiest parts of the world — which they expected to find — but also in cleaner environments like the United States, Canada and Europe.
Most of us don’t consider forests a source of pollution. As natural bodies, they should be good for the environment. But a recent study in Japan shows that older cedar and cypress plantations are causing as much pollution as a poorly managed agricultural field or urban setting.

A team led by environmental engineers from Drexel University are the first independent researchers to take a closer look at the air quality effects of natural gas extraction in the Marcellus Shale region of Pennsylvania. The group used a mobile air quality monitoring vehicle to survey regional air quality and pollutant emissions at 13 sites including wells, drilling rigs, compressor stations and processing areas. Their work establishes baseline measurements for this relatively new area of extraction.
Studies have shown that both air pollution and impaired lung function can cause cognitive deficits, but it was unclear whether air pollution diminishes cognition by reducing breathing ability first or whether air pollution represents an independent risk factor for cognitive deficit. Now a new study conducted by German and Swiss researchers has answered that question: air pollution directly affects cognition and is not mediated by lung function.
