Abstract:
[Objective] To understand the pollution levels of major hazards in the stomatology department of a first-class hospital.
[Methods] From April to July 2012, formaldehyde, total volatile organic compounds(TVOC), carbon dioxide (CO2), and noise in a selected department of stomatology in a first-class general hospital were measured. Room size, number of staff, medicines, and other basic information were also collected.
[Results] The qualified rates of formaldehyde, TVOC, CO2, and noise in the department were 55.15%, 29.09%, 96.36%, and 49.09%. In 7:30, 11:00, and 16:00, the qualified rates of TVOC were 32.27%, 56.36%, and 14.55%; 12.72%, 81.82%, and 70.91% for formaldehyde; 100.00%, 100.00%, and 89.09% for CO2; 100.00%, 21.82%, and 25.45% for noise (all P<0.05).
[Conclusion] In the selected stomatological workplace, TVOC is the leading health hazard, followed by formaldehyde and noise, and CO2 concentrations are qualified for relevant standards.
