| use of br and se in peat to reconstruct the natural and anthropogenic fluxes of atmospheric hg: a 10000-year record from caribou bog, maine. | using br and se as reference elements, the natural and anthropogenic fluxes of atmospheric hg were reconstructed for the past 10,000 years using peat cores from caribou bog, me. in the ombrotrophic peat layers, the average background hg accumulation rate (ar) was 1.7 +/- 1.3 microg m(-2) year(-1) which is comparable with the natural rate of atmospheric hg accumulation reported in other retrospective studies. the average hg ar determined using all peat samples dating from preindustrial times, inc ... | 2006 | 16749680 |
