This study analyzes total suspended particle (TSP) samples collected at two sites of Buenos Aires City (34S, 58W). One site (San Martín) placed 17 km from city center, and the other one at an underground subway station (Diagonal Norte) in downtown Buenos Aires. In both cases, gravimetric analysis has been performed, while elemental analysis using PIXE has been only carried out in the first case. To the best our knowledge, this is the first airborne particle measurement perform at a Buenos Aires underground subway station.
