Carbon dating and pollution
When radiocarbon dating is applied to Carbon dating and pollution sample materials, the results are subject to the Suess effect 1: As this carbon dioxide is incorporated into growing plants in the normal manner, radiocarbon dating of young plant material tends to produce spuriously old dates.
The an discrepancy could, in theory, be as much as yr ref.
However, during a study into the age, origin and vegetational history of upland blanket peats in South Wales, substantially older dates were obtained from recent horizons. The dating of Carbon dating and pollution peat fractions by radiocarbon assay suggested that the substantially older dates derived from contamination by participate pollution during the industrial revolution.
The scale and impact of this pollution are discussed in the context of these results. Suess, H.
The differences as a fraction of the urban tree's radioactivity reflect the local excess 14C-free carbon dioxide from fossil fuel combustion in the urban environment. Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon. It describes how fossil fuel emissions will make radiocarbon dating, used could “age” the atmosphere if pollution continues at its current rate.
