[Health damage of indoor air pollution by decoration on residents].

OBJECTIVE

To explore the health damage of indoor air pollution on residents by detecting the major indoor air pollutants and surveying the health indexes of residents.

METHODS

159 decorated houses were divided into 2 groups by whether the concentration of formaldehyde exceeded national standard. To analyze the health damage of formaldehyde and TVOC on residents, respectively.

RESULTS

The concentrations of formaldehyde of the over standard group and the corresponding under standard group were (0.170 +/- 0.075) mg/m3 and (0.064 +/- 0.022) mg/m3, the concentrations of TVOC of the over standard group and the corresponding under standard group were (2.033 +/- 1.161) mg/m3 and (0.271 +/- 0.142) mg/m3. The incidence of the fatigue, nausea, eye symptoms, symptoms of nose, throat dessication, skin dessication, skin itching sensation and red swelling of the skin of the over standard group was significantly increased than that of the corresponding under standard group (P < 0.05). The incidence of the nausea, skin itching sensation and breathe hard of the TVOC over standard group was significantly increased than that of the corresponding under standard group (P < 0.05).

CONCLUSIONS

Formaldehyde or TVOC will cause severe health damage.
