Mercury Pollution exceeds safety level at dental clinics
study by Sustainable Development Policy Institute (SDPI) reveals high level of
‘indoor mercury pollution’ in the air inside various dental hospitals in
Rawalpindi and Islamabad.
study, conducted in collaboration with European Environmental Bureau (EEB) and
Zero Mercury Working Group (ZMWG), seeks to monitor ‘Mercury emission and
release sites’ in various cities of Pakistan and assess air quality to protect
environment and human health.
the mercury metal and its amalgam are widely used in dental treatment, the SDPI
team visited various dental hospitals in the twin cities and took measurements
of indoor and outdoor air for mercury contamination using Lumex mercury
study findings showed that indoor air at some dental teaching hospitals has
8-20 times higher than permissible level of mercury pollutants for human
health. However, the outdoor air around testing sites showed lower level of
mercury compared to indoor air.
results were duly shared with staff and administration of these institutions
with suggestions to immediately adopt safety measures such as improved
cross-air ventilation, installation of exhaust fans and most importantly a
reduction in the use of mercury, its amalgam and waste at the dental treatment
