Quantitative monitoring of airborne lead pollution by a foliose lichen


, : Quantitative monitoring of airborne lead pollution by a foliose lichen. Water Air & Soil Pollution 32(3-4): 363-378

The potential use of lichens as quantitative monitors of airborne heavy metal pollution has been demonstrated by measurements of Po210, Pb, Cd, Zn, and V levels in sequential growth of the foliose lichen Pseudoparmelia baltimorensis from three localities in the greater Washington, D.C. [USA] area. Samples were dated using the growth rate measured by Lawrey and Hale (1977). Po210, Pb, and V increase with age in a given colony. Higher levels of Pb, V, Cd, and Zn are present in samples from the two more polluted sites. The retention of heavy metals is consistent with trapping by an ion exchange mechanism. Since Po210 is the daughter product of in situ decay of Pb210, accumulated from atmospheric fallout of known rate, its levels can be used to calculate trapping efficiencies of Pb and retrospective fallout rates. These rates are similar to published data from rural and urban areas.

We investigate the process of invasion percolation between two sites (injection and extraction sites) separated by a distance r in two-dimensional lattices of size L. Our results for the nontrapping invasion percolation model indicate that the sta...

Despite expression of the CD95 receptor, however, recently...
