study of lead conentration in the air of gasoline stations of Kerman city

in order to measure the conentration of lead in air of six Kerman gasoline stations,۱۰ air samples were collected from each between ۸:۳۰-۱۲:۳۰ a.m. and then analyzed .lead conentration was  determined by atomic absorption spectrometers.the maximum and minimum of lead conentration were ۰.۸۳۳mg/m۳ and ۰.۴۱mg/m۳ in Khorshid and shahab gasoline stations,respectively.all of the samples were compared with a control station in which the concentration of lead ranged from ۰.۰۸۴mg/m۳ to ۰.۱۶۶mg/m۳.the daily peak lead conentration was between ۹:۳۰-۱۲:۳۰a.m.the mean value in all six stations,was significantly higher than control.in addition,lead conentration in all gasoline stations were lower than lead,s TLV in workplace due to lack of inversion phonimenon in Kerman city.
