Using Peat Records as Natural Archives of Past Atmospheric Metal Deposition,at, i.e. applications to archaeology. To end we present some confounding factors affecting the integrity of the peat record, which must be carefully considered, and lastly we give a few examples of challenges and perspectives for future generations of peat geochemists.

A minority of the metals of environmental interest, such as Hg and to a lesser extent Pb, are thought to be

In addition, the compound must be resistant to microbial degradation and post-depositional transformation, so that any changes in composition and abundance down-core may be confidently attributed to changing contaminant inputs to the aquatic e

https://doi.org/10.1007/978-1-4899-5235-6 chapter we review the environmental records of black carbon and other industrially-derived particles, their analysis, interpretation and relative strengths and weaknesses. Finally we consider two emerging particle types: microplastics and nanoparticles. These latter groups have, so far, received li

The lake sediment contributions are important complements to other observational approaches used in global change research. This chapter focuses on trace metals, polycyclic aromatic hydrocarbons (PAHs) an
