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

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.

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.

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.
