Algae obtain nitrate from deep waters 250 meters beneath the surface For almost three decades, oceanographers have been puzzled by the ability of microscopic algae ("microalgae") to grow in open-ocean areas where there is very little nitrate, an essential nutrient for the algae. In this week's issue of the journal Nature, Monterey Bay Aquarium Research Institute (MBARI) chemical oceanographer Ken Johnson, along with co-authors Stephen Riser at the University of Washington and David Karl at...

A new study exploring the growing worldwide problem of nitrogen pollution from soils to the sea shows that global ratios of nitrogen and carbon in the environment are inexorably linked, a finding that may lead to new strategies to help mitigate regional problems ranging from contaminated waterways to human health. The University of Colorado at Boulder study found the ratio between nitrates -- a naturally occurring form of nitrogen found in soils, streams, lakes and oceans -- and organic...

Treatment results in decreased nitrates, increased antioxidants Searching for ways to improve the nutritional quality of leafy green vegetables, Lithuanian researchers have found success with new technology that features high-density photosynthetic photon flux generated by a solid-state illuminator. The technology, which can be applied in greenhouses for preharvest treatment of leafy vegetables, was found to decrease concentrations of harmful nitrates while allowing some beneficial nutrient...

LAS CRUCES, N.M., April 8 /PRNewswire/ -- A Dona Ana County jury today ruled in favor of Helena Chemical Company in its defamation suit against Arturo Uribe and awarded the company $75,000 in punitive damages based on 7 counts of defamation and injury to the company's reputation. In its decision, the jury agreed that Mr. Uribe had repeatedly defamed the company, by stating the company caused health impacts including cancer and birth defects as well as had the potential to cause...

A team of researchers at the University of British Columbia, along with colleagues at the US Dept. of Energy Joint Genome Institute, has mapped the genome of a microbe that is silently helping to shape the ecology of oxygen-minimum areas in the ocean known as dead zones. "Microbes specialize in metabolic innovation and many can use alternatives to oxygen, including nitrates, sulfates and metals, breathing these compounds instead of oxygen. These adaptations likely enable them to thrive in...

A rapid, less-expensive method for testing nitrate concentration in leafy vegetables did not provide as good results as laboratory tests, U.S. researchers say. Kristy Ott-Borrelli of Washington State University in Pullman, Wash., said measuring nitrate-nitrogen is necessary because when normal plant growth has been altered, the nitrogen usually used by the plant to form proteins remains in the plant in the form of non-protein nitrogen such as nitrate. Excessive amounts of nitrates can become...

Researchers compare rapid potentiometric, colorimetric methods Leafy green vegetables such as lettuce, Asian greens, and spinach can accumulate high concentrations of nitrate"“nitrogen (NO3-N), which are potentially harmful if consumed by humans. To measure NO3-N concentration in plant tissue, many laboratories use ion selective electrodes (ISEs). Relatively inexpensive and portable ISE nutrient monitoring devices, including the Cardy NO3-N meter, are widely used to measure fresh plant...

U.S. researchers found a link between increased levels of nitrates in the environment and food and increased deaths from Alzheimer's and diabetes. Study leader Dr. Suzanne de la Monte of Rhode Island Hospital and colleagues studied the trends in mortality rates associated with aging, such as diabetes, Alzheimer's, Parkinson's, diabetes and cerebrovascular disease, as well as HIV. The study, published in the Journal of Alzheimer's Disease, found strong parallels between age adjusted increases...

Private well water in the United States should be tested annually -- and in some cases more often than that -- the American Academy of Pediatrics advises. Researchers at the National Institute of Environmental Health Sciences, part of the National Institutes of Health, took a lead role in working with the AAP to develop the recommendations on what parents should do if their children drink well water. The policy statement and technical report, scheduled to be published in the June issue of...
