Abstract

LaMotte air sampling pump was used to monitor air that may contains metals, anions and cations in the atmosphere. Concentration of  volatile plumbum (Pb) and cadmium (Cd) was determined by atomic absorption specktrophotometer furnace graphite Model 4100 ZL, while concentration of nitrate (NO3-) dan ammonium (NH4+) were determined by HACH DR 2010 spectrophotometer. Results showed that only the diurnal pattern of Pb was close to the permitted level suggested by Department of Environment that is 1.5 µgm-3  and diurnal pattern of other chemicals species exceeded their background of concentration.

 

Keywords: Air sampling pump, Plumbum, Cadmium, Nitrate, Ammonium
