Other air pollutants include chlorinated fluorocarbons (CFCs) and other "greenhouse" gases, lead and other heavy metals and radon.

LEAD (PERMISSIBLE EXPOSURE LIMIT = 0.05 MG/M) Eight personnel samples were taken for ALGC, B/452, Geon West P-Line to measure exposure levels to lead.

Defendant Union Pacific Resources Company objects to this interrogatory on the grounds it is overly broad, vague,.not limited to the time period relevant in this case nor is it limited to the matters made the basis of this lawsuit, specifically alleged exposure to asbestos fibers and therefore seeks disclosure of information wholly irrelevant to any material issue in this case and not reasonably calculated to lead to the discovery ofadmissible evidence.

Exposure to high concentrations can lead to narcosis, cardiovascular and respiratory irregularity, convulsions, cyanosis and death.
