Nitrogen and sulfur oxides (NOx SOx) emitted from fossil-fuel-fired facilities can be simultaneously absorbed into aqueous mixed solutions of sulfite FeIIL, a ferrous ion coordinated to ligand L (a chelate compound). Usually, the represents an anion ethylenediaminetetraacetic acid (EDTA or edta). oxide (NO) sparingly soluble in water is promptly bound [FeII(edta)(H2O)]2– complex form [FeII(edta)(NO]2–compound. However, [FeII(edta)(H2O]2– oxidized [FeIII(edta)(H2O)]− by NO, NO2, O2, normally...

Beauty salons make a considerable part of the service sector. However, although beauty salon staffs are exposed to vast number ambient chemicals during whole workday, occupational health hazard and indoor air quality in poorly known. Specifically, reports on relations between particulate matter its outdoor or sources rare. Here we studied effects external internal aerosol elemental organic carbon contents. We selected four differing type sources. The approach consisted taking ten eight-hour...

The chelate method can provide simultaneous control of combustion flue gases SO2/NOx by scrubbing into aqueous solutions ferrous chelates, e.g., FeIIedta, an ethylenediaminetetraacetic acid. Because oxidation FeIIedta to completely inactive in the system FeIIIedta, absorption solution requires regeneration. A new proposal here for this process is based on direct reduction FeIIIedta a dithionite ion, S2O42-. rate equation was derived terms rate-determining-step approximation method. kinetic...

This study conducted measurements of PM2.5 (particulate matter with a diameter ≤ 2.5 µm) in Racibórz, Poland, during 2018. Samples were collected daily and analyzed for their chemical composition, specifically, the carbonaceous (elemental organic carbon) water-soluble ionic (Cl–, NO3–, SO42–, Na+, NH4+, K+, Ca2+ Mg2+) components. Additionally, secondary inorganic aerosol (SIA) as well primary carbon (SOC POC, respectively) content was estimated. To identify causes elevated concentrations,...

The purpose of this study is to obtain a detailed picture the spatial and seasonal variability carbonaceous matter in southern Poland. Particulate (PM) samples from eight selected urban rural background sites were analyzed for organic carbon (OC) elemental (EC) (thermal-optical method, “eusaar_2” protocol), content secondary (SOC) primary (POC) was estimated. OC EC dynamics further studied using each thermally-derived fractions (OC1–4, PC, EC1–4). Clear spatiotemporal compounds...

The ambient concentrations of PM-related anions (Cl-, NO3-, SO42-) and cations (Na+, NH4+, K+, Ca2+, Mg2+), total contained in the PM fractions, were investigated a typical urban area within Silesian Agglomeration. A DEKATI low pressure impactor (DLPI) was used to sample separate it into 13 fractions. determined gravimetrically, ion content water extracts—by means chromatography (Herisau Metrohm AG chromatograph). In general, sulfate, nitrate, ammonia had greatest concentrations. PM1 over...
