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.
