    • According to a study done by the U.S. Environmental Protection Agency in 1987, more than 50% of household tap water has lead above the allowed level (20 ppb then) in the first few flush. See ref 1.

    • -2 at 193 nm would heat the lead surface to ∼600 K, just enough to melt but not boil the metal; but the vapor pressure was presumably adequate for lead emissions to be detected. In other words, at the threshold fluences, most photons were channeled to heating the target while few were left for inducing fluorescence off lead atoms. Two-photon processes were therefore unlikely. To model laser heating, see for example: Lee, K. C.; Chan, C. S.; Cheung, N. H. J. Appl. Phys. 1996, 79, 3900-3905.
