Electron spin resonance measurement of •OH radicals following reaction of welding fumes with H2O2 or RAW 264.7 cells

Values represent mean ESR spectra peak heights from 3 experiments. The lower table is the same as above, except using cellular ESR.本次数据为3次独立实验得到的电子自旋共振（Electron Spin Resonance, ESR）波谱峰高的平均值。下表与上述内容一致，仅采用细胞电子自旋共振测试。
