Chemical composition of PM₁₀ and its effect on in vitro hemolysis of human red blood cells (RBCs): a comparison study during dust storm and inversion.

ABSTRACT:

Purpose

This study aimed to investigate chemical composition of PM₁₀ (particulate matter with aerodynamic diameter???10 ?m) 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¯, SO₄¯², 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 ?g/ml.

Results

Daily average of PM₁₀ concentrations in dusty and inversion days were 348.40 and 220.54 ?g/m³, respectively. Most prevalence ionic components were NO₃¯, Cl¯, SO₄¯² and Ca⁺² during dust storm and SO₄¯², 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?ConclusionsAs 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.

Project description:A sampling methodology and a mathematical data treatment were developed that enable to determine not only total suspended particulates (TSP) emitted at channeled sources but also the PM10, PM2.5, and PM1 mass fractions (w10, w2.5, and w1) and emission factors (E.F.), using a seven-stage cascade impactor. Moreover, a chemical analysis was performed to identify the elements present in these emissions. The proposed methodology was applied to different stages of the ceramic process, including ambient temperature (milling, shaping, glazing) and medium-high-temperature (spray-drying, drying, firing, and frit melting) stages. In total, more than 100 measurements were performed (pilot scale and industrial scale), which leads to a measurement time of 1500 h. Related to the mass fractions, in general, the mean values of w10 after the fabric filters operated at high performance are high and with little dispersion (75-85%), and it is also observed that they are practically independent of the stage considered, i.e., they are not significantly dependent on the initial PSD of the stream to be treated. In the case of the fine fraction w2.5, the behavior is more complex (w2.5: 30-60%), probably because the only variable is not the cleaning system, but also the nature of the processed material. Regarding abatement measures, the use of high-efficiency cleaning systems considerably reduces the emission factors obtained for fractions PM10, PM2.5, and PM1. In reference to chemical analysis, the presence of ZrO2 and Ni in the spray-drying and pressing stages, the significant concentration of ZrO2 in the glazing stage, the presence of Pb, As, and Zn in the firing stage, and the presence of Zn, Pb, Cd, and As compounds in the frits manufacturing should all be highlighted. Nevertheless, it should be pointed out that the use of some compounds, such as cadmium and lead, has been very limited in the last years and, therefore, presumably, the presence of these elements in the emissions should have been also reduced in the same way.
