The purpose of this study was to determine if the analytical results (when determining cadmium, lead, and zinc concentrations) for air sample filters prepared and analyzed according to N:OSH Method 7300, differ significantly, from those obtained when the instrument is calibrated using EPA Method 200.7 acid matrix standards. The null hypothesis was that no statistically significant difference, measured at the 95% confidence level, would exist between results obtained from the two calibration standards. Careful standard and sample preparation, the use of an internal standard, and the application of working standard and working internal standard correction factors served to isolate the …

The article evaluates the impact of electrode industry (production of carbon and graphite electrodes in the plant Polgraph SA) on air quality in the Kotlina Sądecka valley and the city Nowy Sącz (Poland). The work presents completed so far environmental investments and the level of emissions of selected air pollutants characteristic of the analyzed facility, including PAHs emissions. Based on the modeling of the dispersion of pollutants in ambient air was determined the levels of pollutant concentrations in the air and location of most affected areas. The calculation results were compared with the results of direct measurements. Particular attention was …
