Relationships between Mass Level of Allergenic Platanus acerifolia Protein 3 (Pla a3) and Redox Trace Elements in the Size-Resolved Particles in Shanghai Atmosphere

Allergenic pollen protein can be released from grains and suspended in the air to cause allergenic reactions. However, its relationship with redox trace elements ambient size-resolved particles has not been reported. Ambient Shanghai’s atmosphere were sampled during Platanus season spring of 2017. Planatus 3 (Pla a3) investigated their was analyzed. Our data demonstrated that mass level Pla a3 ranged 0.41 ± 0.28 7.46 2.23 pg/m3, decreased size range. Mass concentrations (ppb) crustal (Fe, Al, Ca, Mg, Na) 20.11 9.87 1126.22 659.51, while (V, Cr, Mn, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Cd, Cs, Ba, Pb) varied 0.05 0.03 57.53 19.7. levels these according particle size. The Abundance elements, including Fe (R2 = 0.82), Mn 0.54), Cu 0.61), Ba Pb 0.82) significantly related a3, our implied might take syngenetic effects on allergenicity induced by protein.
