摘要：Air samples from the Toluca Valley atmosphere were analyzed by neutron activation technique and atomic absorption was used for Pb determination. Total suspended particulate matter was also determined. On fiber glass filters, the samples were collected and treated with hot concentrated nitric acid and hydrogen peroxide. Pb, Cr, V, Cl, Br, Mn and Ce were measured. The concentration of suspended solids reached values between 90 and 130 µg/m3. These results show that particles found in the air were mainly from vehicle fuel combustion exhaust.
