Se and Hg in Fish Collected Near Power Plants

Arsenic SpeciationBrooks Applied Labs’ data was featured prominently in a recent Environmental Toxicology and Chemistry journal article titled, “Selenium and Mercury in Freshwater Fish Muscle Tissues and Otoliths: A Comparative Analysis”. Authors Robin Reash et. al. presented a study where they measured mercury (Hg), methylmercury (MeHg), and selenium (Se) in muscle tissue and otoliths from 12 species of fish collected from locations influenced by power plant wastewater. There were interesting differences between Se and Hg in their correlation between concentration in the tissues and otoliths and ecological/exposure factors, perhaps explained by the different manners in which Se and Hg bioaccumulate.

Arsenic and Lead in Fruit Juice

Arsenic in Fruit JuiceEveryone knows that too much of a good thing can be bad. But what happens when even a little of a good thing can be harmful?  Consumer reports tested different fruit juices for cadmium, lead, mercury, and inorganic arsenic. The results were startling.  Click here for a detailed description of the juices tested and potential health risks.

BAL is On the Road Again…

EWCPS - Pau, France 2019BAL’s methods are predominantly based on ICP-MS technology so it should surprise no one that the Winter Conference on Plasma Spectrochemistry is one of the highlights of our year. This year’s conference takes place February 3-8 in Pau, France, and Dr. Nausheen Sadiq will be presenting exciting new research on iodine isotopic ratio analysis in kelp samples. BAL’s Dr. Hakan Gürleyük and CEO Michelle Briscoe will also be attending this year’s conference. Please contact us if you will be attending and you’d like to connect, or if you would like more information about this new method!

Battelle’s Conference on Remediation and Management of Contaminated Sediments will be held February 11-14 in New Orleans and BAL’s  Dr. Stephen Springer and Jamie Fox will be attending. Stephen will be presenting a poster on an exciting new method that he developed for the determination of elemental mercury in soils. Please contact us if you will be attending or if you would like more information about this new method!

ACCBIOBAL’s Business Development Director, Russ Gerads, will be attending the International Conference on Accelerating Biopharmaceutical Development in Carlsbad, CA from February 17-20. Schedule a meeting with Russ to learn more about our novel technologies for not just advancing biopharmaceutical development but achieving greater yield and reducing risk in your current operations through chemistry.

Bioavailability of Mercury in Power Plant Wastewater

Power Plant WastewaterStandard regulatory practices limit the total concentration of toxic metals, such as mercury, when discharged from industrial sources, ignoring the importance of speciation and bioavailability. This can result in dischargers spending more on wastewater treatment than might be necessary for adequate environmental protection. In a new article by author Robin Reash, data from Brooks Applied Labs is used to support the conclusion that by utilizing analyses for bioavailable forms of mercury, such as acid-labile mercury and methylmercury, the regulatory limits imposed are likely overly conservative. The article, published in August 2018 in the SETAC journal Integrated Environmental Assessment and Management, is available on-line here.

BAL Scientists Present at NEMC: Presentations Now Available for Download

NEMC LogoAt the National Environmental Monitoring Conference (NEMC) in New Orleans last month, two of our BAL scientists presented in the session “Metals and Metals Speciation Analysis of Environmental Samples”. Annie Carter’s presentation focused on the determination of elemental mercury in soils by selective volatilization, while Brian Smith’s presentation described a method comparison for the analysis of bioaccessible lead and arsenic in soils. Contact us today to learn more about either of these recently developed methods!
