To David Cleveland, a professor of environmental studies at UC Santa Barbara, it seemed as though Santa Barbara County would be a great example of what many are advocating as a solution to the problems of a conventional agrifood network "“"“ a local food system. Santa Barbara County ranks in the top 1 percent of counties in the United States in value of agricultural products, with 80 percent of that value in fruits and vegetables. Farmers here grow some of the best fruits and...

According to a new study published in the journal Environmental Science & Technology, 80 percent of baby products contain toxic or untested chemical flame retardants. The study said a third of products contain a chemical called chlorinated tris, which was removed from children's pajamas in the 1970s because of cancer concerns. The Environmental Protection Agency (EPA) said there is a "moderate level of concern" about links between tris and cancer, developmental problems, reproductive...

Bottlenose dolphins* and beluga whales**, two marine species at or near the top of their respective food webs, accumulate more chemical pollutants in their bodies when they live and feed in waters near urbanized areas, according to scientists working at the Hollings Marine Laboratory (HML), a government-university collaboration in Charleston, S.C. In papers recently published online by the journal Environmental Science & Technology, one research team looked at the levels of persistent...

Indiana University scientists have found chemical flame retardants in the blood of pet dogs at concentrations five to 10 times higher than in humans, but lower than levels found in a previous study of cats. Their study, "Flame Retardants in the Serum of Pet Dogs and in their Food," appears this month in the journal Environmental Science & Technology. Authors are Marta Venier, an assistant research scientist in the School of Public and Environmental Affairs, and Ronald Hites, a...

Online calculator allows households around the country to track -- and try to reduce -- carbon footprint Tips to reduce your carbon footprint frequently include buying compact florescent light bulbs, taking your own bag to the grocery store or buying local produce. But how much difference do these actions make? A new study by researchers at the University of California, Berkeley, suggests that who you are and where you live make a big difference in which activities have the largest impact....

The ongoing spread of non-native mussels in the Great Lakes has caused "massive, ecosystem-wide changes" throughout lakes Michigan and Huron, two of the planet's largest freshwater lakes, according to a new University of Michigan-led study. The blitzkrieg advance of two closely related species of mussels"”the zebra and quagga"”is stripping the lakes of their life-supporting algae, resulting in a remarkable ecological transformation and threatening the multibillion-dollar U.S....

"We were not expecting to find such high levels of PCBs, highly toxic compounds that are considered as priority compounds by European legislation, in a region such as the western coast of Africa", Ailette Prieto, a researcher at the University of the Basque Country (UPV/EHU-Spain) and co-author of a study published in the journal Environmental Science & Technology, tells SINC. PCBs, which some studies have shown to be carcinogenic compounds, were used years ago as dielectric fluids in...

New research from Chalmers and SIK shows that impact on the climate is much greater than current estimates indicate. The researchers are now demanding that indirect effect on land be included when determining a product's carbon footprint Increased export of Brazilian beef indirectly leads to deforestation in the Amazon. New research from Chalmers and SIK that was recently published in Environmental Science & Technology shows that impact on the climate is much greater than current...

Scientists are reporting for the first time that previously unrecognized substances released by algae blooms have the potential to act as endocrine disruptors, which can interfere with the normal activity of reproductive hormones. The effect is not caused by microcystin toxins, long recognized as potentially harmful to humans and aquatic animals, but as yet unidentified substances. As a result, the scientists are calling for a revision of environmental monitoring programs to watch for these...

UC researchers tested holiday bulbs, traffic lights and car beams Those light-emitting diodes marketed as safe, environmentally preferable alternatives to traditional lightbulbs actually contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research. "LEDs are touted as the next generation of lighting. But as we try to find better products that do not deplete energy resources or contribute to global warming, we have to be vigilant about the...
