title: [Correlations between mutagenicity of airborne particles and concentrations of air pollutants].
abstract: With highly efficient aspirometry method there were sampled airborne particles in different parts of Wrocław in winter and summer. Organic compounds adsorbed on the particles were extracted for 8 hours in Soxhlet apparatus. Concentration of PAHs and benzo(a)pyrene was determined with GC-MS. Mutagenicity of particles was examined with Ames test. Concentrations of airborne particles ranged from 17-144 mg/m3, and organic compounds adsorbed on the particles--1.1-28.6 mg/m3. Concentrations of PAHs from EPA list ranged from 8.3-1211.6 ng/m3, benzo(a)pyrene's ones--from 4.5-709 ng/m3. Airborne particles sampled in many different locations of Wrocław in winter and summer displayed mutagenic activity. Air volumes polluted with the particles resulting in mutagenic effect in Ames test in TA 98 strain without activation with fraction S9 ranged from 0.25-42.5 m3. They displayed correlation with concentration of airborne particles (correlation index -0.35), organic compounds adsorbed on the particles (correlation index -0.58), PAHs from EPA list (correlation index -0.52) and benzo(a)pyrene (correlation index -0.52). Physiochemical indexes of air pollution only approximately indicate health hazards caused by mutagenes and cancergenes adsorbed on airborne particles. Therefore monitoring of air pollution should be supplemented with testing their mutagenicity with Ames test.
