Used in health-care settings for centuries, mercury is a toxic metal that poses a threat to human health and the environment.
Medical thermometers and sphygmomanometers (devices which measure blood pressure) contain mercury and are harmless as long as they remain intact.
However, when these devices break or are taken out of service, the mercury they contain can escape into the environment where it vaporises, exposing health care workers and patients to harmful fumes. Inhalation can cause damage to the lungs, kidneys and nervous system, while the waste generated can contaminate the immediate area of the spill, as well as a facility’s wastewater.
Such equipment breakages are common.
Led by the United Nations Environment Programme (UNEP), with funding from the Global Environment Facility (GEF) and executed by the World Health Organization (WHO), the Phasing out mercury measuring devices in healthcare project will develop and implement nation-wide strategies to stop the import, export and manufacture of thermometers and sphygmomanometers, encourage the adoption of accurate, affordable and safe mercury-free alternatives, while improving the management of mercury-containing medical waste.
The five-year project will bring each country in line with international best practice, educating procurement officers on the efficacy of widely available alternative devices and raising awareness amongst manufacturers and the public, as per WHO recommendations and the Minamata Convention on Mercury.
Certain digital thermometers can be up to one-third cheaper than their mercury counterparts when considering the entire lifecycle of both instruments, all while maintaining the same level of clinical accuracy.
Director of Public Hygiene at Burkina Faso’s Ministry of Health and Public Hygiene, Dr. Anta Zida, said the country was keenly aware of the need to reform its healthcare sector to meet Burkina Faso’s international obligations.
The project aims to phase out mercury-added thermometers and sphygmomanometers at a rate of 20 percent per year, reducing spillages by 23,350kg and improving the lives of over 1.8 million people.
