2023 Mercury Inventory Report Published by the EPA

Posted by Sara Kennedy on Feb 2, 2024 2:44:44 PM

Mercury is a persistent, global, and toxic element. It does not degrade, but it changes forms as it cycles through the environment. When mercury is emitted, it can be transported over long distances and re-deposited.

Mercury Stability in Hydrochloric Acid vs. Nitric Acid

Posted by Sara Kennedy on Jan 5, 2024 1:51:10 PM

Teledyne Leeman Labs has been in the mercury (Hg) analysis business for more than 30 years. We have had a variety of product lines reach new markets and address tighter regulations. In that time, one thing has remained constant across all our instruments: the need for accurate mercury standards to form the building blocks of the calibration curve. Analytical results are only as reliable as the calibration curve to which they are compared, and creating stable mercury standards comes with unique challenges.

Going for the Gold: Benefits of a Gold Trap in Mercury Analysis

Posted by Aaron Keller on Jul 25, 2023 12:05:30 PM

The gold standard. Go for the gold. A gold medal.

Gold is highly prized for its beauty, as a measure of wealth, a jewelry mainstay and more. When it comes to the analysis of mercury, gold has a very particular value in obtaining data at the ultra-trace level.

Trace Elemental Analysis by Atomic Absorption Spectroscopy

Posted by Sara Kennedy on Jan 23, 2023 4:17:03 PM

Trace elemental analysis

Teledyne Leeman Labs has specialized in trace elemental analysis for over 40 years. With initial success in Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES), also referred to as Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), Teledyne Leeman Labs went on to develop innovative product lines. Those included branching out into various elemental analysis techniques, including DC Arc and Mercury Analysis. Our elemental analysis instruments can be found in laboratories across the world, providing service to a range of industries. From agriculture to aerospace and food to forensics, Teledyne Leeman Labs is dedicated to providing world-class instruments for trace elemental analysis.

Mercury Determination in Tuna – a Thorough Analysis

Posted by Betsey Seibel on Jan 24, 2017 9:00:00 AM

The proliferation of mercury in fish is a well-documented environmental problem. Mercury accumulates in fish tissue from natural and anthropogenic source in bodies of water where the fish live. The microorganisms at the base of the aquatic food change convert the elemental mercury into organic methylmercury, which binds tightly to the proteins in fish tissue.

Could Remediated Ammo Manufacturing Site in Ohio be New Home to Luxury Apartments?

Posted by Betsey Seibel on Sep 27, 2016 2:43:48 PM

An abandoned ammo factory in Kings Mill, Ohio is on the EPA list as one of the most contaminated sites in the country. The site, once home to the Peter’s Cartridge Company, could be the new home to luxury apartments and commercial office space overseeing the Little Miami River. The $25 million plan, which includes 120-130 apartments and 23,000 square feet of commercial space, is dependent on whether the site can be remediated from the mercury, copper and lead that has contaminated the soil for more than a century.

Urban House Dust and Mercury Contamination

Posted by Betsey Seibel on Oct 26, 2015 5:41:06 PM

Soil and dust in homes often become the primary resting places for environmental toxins such as metals and metalloids that come from vehicle traffic and a variety of industrial sources. Residents within urban settings have a higher rate of exposure to contaminated dust from inhalation, ingestion and dermal contact. As a result, dust ingestion is often regarded as the primary source of low-dose mercury in urban children who spend much of their time indoors.
