【 摘 要 】

The objective ofthis study was to assess a new monitoring technique of particulate and tracemetals in the atmosphere via the use of a passive sampler of air pollutantsin the city of Goiânia. The average particulate weight and average concentrationsof metals Fe, Cr, Zn, Pb, Cu, Mn, and Cd were 0.1104 g and 257.5; 23.4; 17.8;6.7; 1.9; 0.8; 0.2 μg/m2/day,respectively. Higher Pb and Cr concentrations were obtained in areas with intensetraffic. This study revealed that it is possible to monitor trace metals withpassive sampling, developed at a low cost and operational facility.
