NUCON International Study Finds Mercury Vapor in Recycling Containers Reaches Unsafe Levels, Indicating Need for Adsorption

NUCON International Inc., Columbus, OH, a worldwide leader in providing gas, vapor and liquid phase adsorption solutions to the Nuclear Power and other industries, has announced the results of recent tests to determine the levels of mercury vapor that accumulate in mercury lamp storage and shipping containers when lamps inside the containers are broken. The study concluded that mercury vapor levels within containers containing broken fluorescent lamps exceed health and safety exposure limits and guidelines. NUCON also ran parallel tests using a new adsorbent technology and achieved more than 95 percent mercury vapor reduction within the same containers.

Tests were conducted by breaking fluorescent lamps inside a sealed vapor-containing bag and box in a specially designed test chamber and continuously measuring vapor levels inside the bag. The results indicated that opening a package containing broken fluorescent lamps and/or CFLs presents a significant risk of mercury vapor exposure, potentially rising well above both the OSHA 8-hour permissible exposure limit of 100 ug/m3 and the NIOSH (National Institute for Occupational Safety and Health) IDLH (immediately dangerous to life and health) level of 10,000 ug/m3.

NUCON ran multiple parallel tests using a new, patent-pending adsorbent substrate they developed in conjunction with VaporLok Products, LLC, Mankato, MN, The new substrate was impregnated with carbon and treated with a variety of inert chemicals, effectively adsorbing and capturing the mercury vapor. This new, carbon-based adsorbent technology, called VaporLokCapture™, is designed to adsorb mercury vapor from any device or product containing mercury.  You can view a short animated depiction of this process at
