ABSTRACT

 

            Exposure to ambient particulate matter (PM) has been associated with a number of adverse health effects. Studies have suggested that such adverse health effects may derive from oxidative stress, initiated by the formation of reactive oxygen species (ROS) within affected cells.

           The present study aims to assess physical characteristics and chemical compositions of PM and to correlate the results to their redox activity. PM10 (mass aerodynamic diameter ≤10 μm) and PM2.5 (mass aerodynamic diameter ≤2.5 μm) were collected in an urban area (Craiova city). The concentrations of organic carbon (OC) and elemental carbon (EC) were measured.

                The Cleland’s reagent was used to measure the redox activity of PM.

            Results show that the concentration of OC is greater than the one of EC (the volatile organic compounds are responsible for this) and that PM2.5 have higher concentrations of OC and EC than PM10.

 

                KEYWORDS: air quality, particulate matter (PM10, PM2.5), Cleland's reagent (DTT), organic carbon, elemental carbon.
