Landfill Leachate: a Source of Mercury Contamination in Groundwater

Posted by Sara Kennedy on Feb 15, 2024 3:41:51 PM

What is a Municipal Solid Waste Landfill?

Have you ever wondered what happens to a bag of garbage once it has been collected on trash day? If it is collected from a household or commercial site, it will likely end up at the Municipal Solid Waste Landfill (MSWLF). These are highly engineered facilities that are

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.

Bright ideas to Reduce Mercury in the Energy Stream

Posted by Sara Kennedy on Jan 8, 2024 3:50:31 PM

Coal generates a lot of unwanted pollution when mined and burned for fuel, yet it is a major source of energy for everything from generating electricity to making steel. Coal is a reliable source of energy and heat, but also a reliable pollution generator, even under current regulations.

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.

New USEPA Rule Proposal Directed at Wastewater Produced at Coal Fired Utilities

Posted by Jeff Forsberg on Sep 1, 2023 8:30:42 AM

President Biden’s Executive Order 13990 directed the U. S. Environmental Protection Agency to undergo a policy and regulation review of changes to the Clean Air Act set forth during President Trump’s administration. The order instructed the EPA to suggest revisions and/or cancellation of regulations and policies that at first glance do not seem to be in the best interest of public health.

Run it, don’t pollute it — filter your mercury exhaust

Posted by Aaron Keller on Jun 15, 2023 11:43:46 AM

Mercury poisoning is a serious concern for those of us who directly work with mercury. Mercury is a heavy metal with many adverse side effects for people and the environment, even in relatively small amounts. That is why mercury analyzers are useful for testing where health concerns exist; you likely use one in your own lab if you’re reading this.

Do you know your QuickTrace M-8000's PMT voltage?

Posted by Sara Kennedy on Jun 5, 2023 10:03:20 AM

We often get asked if there is an ideal photo multiplier tube (PMT) voltage for the QuickTrace® M-8000. The truth is the optimal value is unique to each instrument’s detector. It varies from instrument to instrument. During the initialization process, after connecting to the QuickTrace software, the M-8000 will select the voltage that is right for the PMT inside that system. This is the same process as clicking the Auto Select Voltage button in the Instrument Control menu. So, why is there another Set Volts option in that same menu?
