Studies on health effects of the yellow dust collected in Japan, with special reference to relationship between histological changes in the respiractory tract of rats and absorbed pollutants.

通过化学分析、超氧阴离子生成活性和肺组织病理学变化，评价了黄尘的生物学效应。结果表明，黄尘吸附污染物对这些生物学指标的重要性。黄尘样品中致癌物的检出量远低于单独诱发肺癌的水平。应明确黄尘对肺癌及其他与PM2.5暴露相关疾病的协同或相加作用。

Biological effects of the yellow dust were evaluated by chemical analysis, superoxide generation activity and histological changes of rat lung tissue. Results indicated the importance of adsorbed pollutants on the yellow dust on these biological indices. Detected amount of carcinogens in the yellow dust samples was far low to induce lung cancer alone. It should be clarify that the synergetic or additive effect of the yellow dust on the lung carcinogenesis and other diseases related to PM2.5 exposure.
