Ae. Ali et al., SEASONAL-VARIATION OF PB CONCENTRATION IN AIRBORNE PARTICLES AT SEVERAL SITES OF DEBRECEN CITY, Journal of radioanalytical and nuclear chemistry, 186(1), 1994, pp. 23-33
Lead concentrations of atmospheric particulate matter were measured sy
stematically by X-ray fluorescence method at three sites of Debrecen c
ity over long periods. The time dependence of Pb concentration level i
n air was investigated and compared with literature data. High variati
on was found in lead concentration values with respect to place and ti
me.
