Available in PDF, EPUB and Kindle. Book excerpt: "This study was undertaken to determine the morphology, texture, size and abundance of smelter dust trapped in humus. Elemental mass balance indicates that this dust contributes a small fraction of the overall geochemical value of the sediment. Although emission of smelter-derived dust is likely the primary mechanism for delivery of metal to humus, the preserved particles are not the current primary residence site of metal in the humus. This suggests that, soon after deposition, weathering processes have released metals and other elements from the dust to the humus"--Provided by publisher.
