Abstract

Purpose: This study aimed to investigate chemical composition of PM10 (particulate matter with aerodynamic diameter ≤ 10 μm) during dust storm and inversion in Tehran and hemolysis effects. Methods: PM10 was sampled in Tehran, Iran, during dust storm and inversion conditions. Water soluble ions (F, Cl, NO2, NO3, SO42, Na+, K+, NH4 +, Ca+2, Mg+2) and elements (Al, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Se, Sn, Sr, V, Zn, Pt, Rh, Pd, As and Si) were analyzed by ion chromatograph (IC) and inductively coupled plasma optical emission spectrometer (ICP-OES), respectively. Hemolysis was examined as in vitro at PM10 concentrations of 50-300 μg/ml. Results: Daily average of PM10 concentrations in dusty and inversion days were 348.40 and 220.54 μg/m3, respectively. Most prevalence ionic components were NO3, Cl, SO42 and Ca+2 during dust storm and SO42, NO3, Cl and NH4 + during inversion. Si, Fe and Al had the maximum values in both conditions. Particles associated with both conditions induced hemolytic responses. PM10 from dusty day showed a higher hemolysis percent (10.24 ± 4.67%) than inversion (9.08 ± 5.47%), but this difference was not significant (p = 0.32). Hemolytic effects were significantly intensified by increased PM concentrations (p < 0.001) in a dose-response manner. Conclusions: As the results, chemical composition of sampled particles from inversion days and dust storm was different from each other. Hemolytic effects of particles during dust storm were more than inversion days. However, this difference was not statistically significant. © 2019 Springer Nature Switzerland AG.
