Title Mercury Spill Results in Multiple Families Having to Temporarily Relocate
Introduction EMSL Analytical provides mercury, lead and other heavy metal testing services to identify potential exposure risks and to assess remediation projects.

St. Louis, Missouri, December 20th, 2021

The U.S. Environmental Protection Agency (EPA) announced last month that on-scene coordinators (OSCs) and contractors were responding to several residences in Wentzville, Missouri. High levels of mercury were found after a child was taken to a suburban St. Louis hospital suffering from elevated mercury blood levels. Children in the residence reportedly had been playing with, and spilled, a small vial of elemental mercury approximately five months earlier.

According to EPA, the hospital called EPA Region 7’s Emergency Spill Line after they determined that the child was suffering from mercury poisoning. The Missouri Department of Natural Resources performed an initial mercury vapor screening of the child’s residence and elevated concentrations were detected throughout the home. Further assessments by EPA OSCs then found high levels of mercury vapors in two other residences. The families from the impacted residences were relocated, while response crews continued to remove contaminated personal items and materials from the homes to decrease mercury vapor concentrations.

At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless, and toxic vapor. Mercury is a neurotoxin and possible symptoms of mercury poisoning listed by EPA include:

  • Loss of peripheral vision
  • "Pins and needles" feelings, usually in the hands, feet and around the mouth
  • Lack of coordination of movements
  • Impairment of speech, hearing, walking and/or
  • Muscle weakness


“Years ago, mercury was used to make products like thermometers, switches and even some light bulbs,” said Joe Frasca, Senior Vice President of, Marketing at EMSL Analytical, Inc. “Unfortunately, some of these products still remain in homes and buildings. If a mercury spill occurs, experienced professionals should be involved to ensure that the level of contamination is identified and is then properly remediated. Environmental testing for mercury provides the information needed to identify, document and verify environmental conditions are once again safe for building occupants.”   

To help in these efforts, EMSL Analytical offers mercury and other heavy metal testing services. They provide all of the sampling supplies needed and have even sponsored an educational video about mercury exposure and health effects that can be seen at: https://youtu.be/QVu5js60PWI
