Calcutta Pollutants: Part II. Polynuclear Aromatic Hydrocarbon and Some Metal Concentration on Air Particulates During Winter 1984

Abstract
The concentration of 25 polynuclear aromatic hydrocarbons (PAH) and 12 metals on air-particulate matter of Calcutta city were determined during January–February 1984. X-ray fluorescence (XRF) was applied for determination of metal concentration and gas chromatography–mass spectrometry (GC–MS) for PAH determination. Both PAH and metal concentrations found are present at higher concentration when compared with cities in Europe and USA.
