Nasal effects of a mixture of volatile organic compounds and their ozone oxidation products.

Journal Article

Objective

Our objective was to determine if low levels of a mixture of volatile organic compounds (VOCs) and their ozone (O3) oxidation products, similar to what might be found in "sick buildings," cause nasal irritation and inflammation under controlled exposure conditions.

Methods

Healthy, nonsmoking women (n=130) completed 2-hour controlled exposures to VOCs, VOCs and O3, and a masked air "MA" control in random order at least 1 week apart. VOCs and O3 concentrations were approximately 25 mg/m and approximately 40 ppb, respectively. Nasal symptoms were rated before, during, and after exposure. Nasal lavage fluid was analyzed for polymorphonuclear cells, total protein, interleukin-6, and interleukin-8.

Results

We found no significant differences in symptoms or markers of nasal inflammation between exposure conditions.

Conclusions

Results suggest that VOCs and their oxidation products may not cause acute nasal effects at low concentrations.
