“…Maximal concentrations of particulate matter are generally occurred during winter and minimal in the rainy season areas (Karaca et al, 1995;Soni and Agarwal, 1997;CMRI, 1999;Ghose and Majee, 2000;Tayanc, 2000;Nanda and Tiwary, 2001;Reddy and Ruj, 2003). However, for certain urban areas maximal concentrations of particulate matters are also observed in summer season (Crabbe et al, 2000;Ferreira et al, 2000;Meenalbal and Akil, 2000;Almbauer et al, 2001;Triantafyllou, 2003). The concentration of particulate matters vary with the meteorological parameters and a relation also exist between TSP and PM 10 (Monn et al, 1995;Tayanc, 2000;Jones et al, 2002;Triantafyllou et al, , 2003Triantafyllou and Kassomenos, 2002).…”
