The South Karelia Air Pollution Study : Effects of low-level exposure to malodorous sulfur compounds on symptoms.
Exposure to very low levels of ambient-air malodorous sulfur compounds and their effect on eye irritation, respiratory-tract symptoms, and central nervous system symptoms in adults were assessed.
A cross-sectional self-administered questionnaire (response rate=77%) was distributed during March and April 1992 to adults (n=336) who lived in a neighborhood that contained a pulp mill and in a nonpolluted reference community (n=380).
In the exposed community, the measured annual mean concentrations of total reduced sulfur compounds and sulfur dioxide measured in two stations were 2 to 3 mug/m3 and 1 mug/m3, respectively.
In the reference community, the annual mean concentration of sulfur dioxide was 1 mug/m3.
The residents of the community near the pulp mill reported an excess of cough, respiratory infections, and headache during the previous 4 wk, as well as during the preceding 12 mo.
The relative risk for headache was increased significantly in the exposed community, compared with the reference area : the adjusted odds ratio (aOR) was 1.83 (95% confidence interval [95% CI]=1.06-3.15] during the previous 4 wk and 1.70 (95% Cl=1.05-2.73) during the preceding 12 mo.
The relative risk for cough was also increased during the preceding 12 mo (aOR=1.64,95% Cl=1.01-2.64).
These results indicated that adverse health effects of malodorous sulfur compounds occur at lower concentrations than reported previously.
