Toward a standardized procedure for charcoal analysis

Quaternary Research, 2020
AbstractSedimentary charcoal records are used for understanding fire as an earth system process; however, no standardized laboratory methodology exists. Varying sample volumes and chemical treatments (i.e., type of chemical for length of time) are used for the deflocculation and extraction of charcoal from sediment samples.

Improving the efficiency of sediment charcoal image analysis

The Holocene, 2021
Imaging of charcoal particles extracted from lake sediments provides an important way to understand past fire regimes. Imaging of large numbers of particles can be time consuming. In this note we explore the effects of subsampling and extrapolation of area on estimates of sum charcoal area, using resampling of real and simulated data sets and propose ...

Archaeological Charcoal Analysis in New Zealand

Journal of Pacific Archaeology, 2017
Charcoal is well preserved and abundant in many New Zealand archaeological sites. When identified to species it provides a means of reconstructing past vegetation communities adjacent to occupation sites. However, the way charcoal deposits accumulated needs to be considered before species identifications are converted into vegetation reconstructions ...

Chemical analysis and potential health risks of hookah charcoal

Science of The Total Environment, 2016
Hookah (waterpipe) smoking is a very common practice that has spread globally. There is growing evidence on the hazardous consequences of smoking hookah, with studies indicating that its harmful effects are comparable to cigarette smoking if not worse. Charcoal is commonly used as a heating source for hookah smoke.
