Genes that Methylate Mercury Identified

When mercury is released into the environment it can be transformed from inorganic mercury into the far more toxic form of methylmercury. Scientists have known for decades that bacteria are largely responsible for the methylation of mercury, but the precise mechanism by which this occurs has been a mystery. Researchers at Oak Ridge National Laboratory recently identified two genes that appear to allow certain strains of bacteria to methylate mercury. This exciting discovery may help lead to ways of limiting methylmercury production in the environment.

Join us at Pittcon Conference & Expo 2013

Organized by The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy, a not-for-profit educational corporation (comprised of the Spectroscopy Society of Pittsburgh and the Society for Analytical Chemists of Pittsburgh), the Pittcon Conference & Expo attracts more than 17,000 attendees representing industry, academia, and government from over 90 countries. Visit us during Pittcon 2013, March 17-21 in Philadelphia, PA, at booth #1328 where we’ll be exhibiting our highly specialized laboratory instrumentation for mercury analysis. Our MERX modular mercury analyzers have proven to be among the most accurate, precise, and reliable analyzers available for the determination of low-level mercury and mercury species in environmental samples. Our analyzers are actively in use at some of the best universities, research institutions, and public and private laboratories around the world. Visit us at Pittcon or contact us today to learn more!

Join us at the Engredea 2013 Tradeshow

Natural Products Expo West, the world’s largest natural and organic products trade show, is attended by over 58,000 industry members and is co-located with Engredea, Nutracon, the Beer, Wine & Spirits Marketplace, and the Fresh Ideas Organic Marketplace, where over 3,000 exhibitors will be showcasing products in the categories of natural, specialty, and organic foods, dietary supplements, and health & beauty. Visit us during Engredea, March 8-10, in Anaheim, CA, at booth #575 in Hall A where we’ll be providing information to manufacturers, distributors, and retailers of natural products about how we are uniquely capable of providing them with the specialized low-level metals testing and metals speciation analyses (such as for inorganic arsenic, methylmercury, or hexavalent chromium) they’ll need to comply with upcoming regulations, such USP <2232>.

Interlab Study: Arsenic Speciation Analysis

There is a growing awareness regarding the levels of arsenic in many types of food and beverages. However, the relative toxicity of the arsenic depends largely upon the species of arsenic that is present. Regulators and manufacturers are increasingly interested in distinguishing between the various species of arsenic found in food and beverages, and not just the total arsenic concentrations, when addressing human health concerns. The analytical techniques for determining the specific arsenic species in food and beverages can vary considerably from laboratory to laboratory. On behalf of the AOAC Contaminant Community, Brooks Rand Labs is conducting an arsenic speciation interlaboratory comparison study.
