T. Martinez et al., DETERMINATION OF POLLUTANTS IN DWELLINGS BY NEUTRON-ACTIVATION ANALYSIS AND X-RAY-FLUORESCENCE, Journal of radioanalytical and nuclear chemistry, 216(1), 1997, pp. 37-39
Metallic pollutants were measured in dwellings in Mexico City by instr
umental neutron activation analysis (INAA) and X-ray fluorescence tech
niques. Monitoring was performed in the west side of the city and in t
he winter season. In general the average concentration of contaminants
collected, when compared with the average concentrations reported in
a previous paper, have increased with time and in the particular case
of lead and mercury some samples are above the indicative WHO maximum
levels.
