title: [Mutagenicity and anti-mutagenicity assay of airborne suspended particles in Shijiazhuang city].
abstract: Samples of airborne suspended particles collected from five air monitoring sites in Shijiazhuang City in 1993 were analyzed with rapid synchronous mutagenicity and anti-mutagenicity tests. It revealed airborne suspended particles collected had direct and indirect mutagenicity, but no anti-mutagenicity, and there was seasonal difference in their mutagenicity, which showed a decreasing trend with an order of winter, spring, summer and autumn. Mutagenicity related positively to air concentrations of total suspended particles and sulfur dioxide, inversely to those of ozone, and did not related to those of nitrogen oxide and carbon monoxide.
