Lead particulates in air at UTEP monitor site


Lead: (quarterly mean in micrograms/cubic meter) El Paso, TX
All the data points are from the East Robinson UTEP monitor site.
This is a chart of the quarterly Pb (lead) readings for the eleven years.

The values begin to get smaller after the smelter closed, in 2/1999
