Lazareth, C.E., P. Willenz, J. Navez, E. Keppens, F. Dehairs, and L. André. 2000. Sclerosponges as a new potential recorder of environmental changes: Lead in Ceratoporella nicholsoni. Geology 28:515-518.
Lead concentrations have been analyzed on a 223 yr profile through the aragonitic skeleton of the reef-building Caribbean sclerosponge Ceratoporella nicholsoni by using laser-ablation inductively coupled plasmaŋmass spectrometry. A parallel study of the d13C distribution in the skeleton validates the previously established mean annual growth rate of 230 ĩm/yr, at least for long-term important environmental changes. The Pb trend in the specimen displays a general increase from 0.30 ppm ca. A.D. 1760 to 2.15 ppm ca. A.D. 1984; a major threefold increase occurred after 1930. This Pb profile is analogous to results acquired from ice or coral cores and clearly highlights the potential of sclerosponges as a new proxy of environmental changes for time series extending over several centuries.
