致敏花粉蛋白可从花粉粒中释放出来并悬浮在空气中，引发过敏反应。然而，环境中按粒径分级的颗粒物中的致敏蛋白及其与氧化还原微量元素的关系尚未见报道。在2017年春季悬铃木花粉季期间，对上海大气中按粒径分级的环境颗粒物进行了采样。对悬铃木花粉蛋白3（Pla a3）以及环境颗粒物中的氧化还原微量元素进行了研究，并分析了它们之间的关系。我们的数据表明，按粒径分级的颗粒物中Pla a3的质量水平在0.41 ± 0.28到7.46 ± 2.23皮克/立方米之间，且随粒径范围增大而降低。按粒径分级的颗粒物中地壳元素（铁、铝、钙、镁、钠）的质量浓度（十亿分率）在20.11 ± 9.87到1126.22 ± 659.51之间，而微量元素（钒、铬、锰、钴、镍、铜、锌、镓、砷、硒、铷、锶、镉、铯、钡、铅）在0.05 ± 0.03到57.53 ± 19.7之间。这些微量元素的质量水平随粒径减小。按粒径分级的颗粒物中氧化还原微量元素的丰度，包括铁（R² = 0.82）、锰（R² = 0.54）、铜（R² = 0.61）、钡（R² = 0.82）和铅（R² = 0.82）与Pla a3的丰度显著相关，我们的数据表明氧化还原微量元素可能对Pla a3蛋白诱导的致敏性产生协同作用。
Allergenic pollen protein can be released from pollen grains and suspended in the air to cause allergenic reactions. However, the allergenic protein and its relationship with redox trace elements in ambient size-resolved particles has not been reported. Ambient size-resolved particles in Shanghai’s atmosphere were sampled during the Platanus pollen season in the spring season of 2017. Planatus pollen protein 3 (Pla a3) and redox trace elements in the ambient particles were investigated and their relationship was analyzed. Our data demonstrated that the mass level of the Pla a3 in the size-resolved particles ranged from 0.41 ± 0.28 to 7.46 ± 2.23 pg/m3, and decreased with the size range. Mass concentrations (ppb) of crustal elements (Fe, Al, Ca, Mg, Na) in the size-resolved particles ranged from 20.11 ± 9.87 to 1126.22 ± 659.51, while trace elements (V, Cr, Mn, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Cd, Cs, Ba, Pb) varied from 0.05 ± 0.03 to 57.53 ± 19.7. Mass levels of these trace elements decreased according to particle size. The Abundance of redox trace elements, including Fe (R2 = 0.82), Mn (R2 = 0.54), Cu (R2 = 0.61), Ba (R2 = 0.82), and Pb (R2 = 0.82) in the size-resolved particles was significantly related to that of Pla a3, and our data implied redox trace elements might take syngenetic effects on the allergenicity induced by Pla a3 protein.
