Mercury Reduction Program

Historical Overview

Elemental mercury, also known as metallic mercury, poses significant environmental and health hazards. Recognizing these risks, the University of Missouri (MU) initiated two comprehensive Mercury Reduction Programs:

• 1999–2001: The inaugural program focused on identifying and eliminating mercury-containing devices across campus laboratories and facilities.
• 2002–2011: Building upon the initial success, the second phase expanded efforts to further reduce mercury usage, emphasizing education and the adoption of safer alternatives.

These initiatives substantially decreased the presence of elemental mercury on campus, enhancing safety and environmental stewardship.

Ongoing Commitment

While the formal programs have concluded, MU remains dedicated to minimizing mercury use. The principles established during the Mercury Reduction Programs continue to guide current practices. Environmental Health & Safety (EHS) encourages the campus community to:

• Submit Mercury-Containing Devices: Utilize the EHS Assistant portal to request the collection of mercury-containing items. This service is provided at no charge.
• Avoid Purchasing Mercury Devices: Refrain from acquiring new equipment that contains elemental mercury.
• Seek Mercury-Free Alternatives: Opt for safer, non-mercury devices in laboratories and other settings.

Mercury-Free Alternatives

Advancements in technology have led to the development of reliable mercury-free instruments that match or surpass the performance of their mercury-containing counterparts. Common alternatives include:

• Thermometers:
  • Digital Thermometers: Utilize electronic sensors for accurate readings.
  • Alcohol or Galinstan Thermometers: Employ non-toxic liquids as substitutes for mercury.
• Sphygmomanometers (Blood Pressure Devices):
  • Aneroid Devices: Mechanical gauges without mercury.
  • Digital Monitors: Electronic devices offering ease of use and accurate measurements.
• Manometers and Barometers:
  • Digital Pressure Gauges: Provide precise pressure readings without mercury.
  • Water or Oil-Based Manometers: Use safe fluids as alternatives.
• Lighting and Electrical Equipment:
  • LED Lamps: Energy-efficient and mercury-free lighting options.
  • Electronic Switches: Replace mercury tilt switches in various applications.

For a comprehensive list of mercury-free alternatives and guidance on transitioning, refer to the EPA's resources on mercury alternatives.
