Oil carbon dating

Their integration also enables us delineate the initial radium isotopic signatures of the spill waters, indicating the nature of the wastewater that caused the spill." By reconstructing the initial radium isotope ratio of the wastewater that contaminated the soil, Vengosh's team can determine the source of the fluids even if the wastewater itself is no longer present at the site. "Radioactive isotopes reveal age of oil, gas wastewater spills: Three new tools will be useful in areas where contamination may be new or old." Science Daily. In a recent study, researchers tested a method that extracted a ...High levels of two potentially hazardous contaminants, ammonium and iodide, have been documented in wastewater being discharged into streams and rivers from oil and gas operations in Pennsylvania. Radiocarbon measurements have a range of uses, from analysing archaeological finds, to detecting fraudulent works of art, to identifying illegal ivory trading, to assessing the regeneration of brain cells in neurological patients.

The Duke team published its peer-reviewed study April 28 in the journal .

Fossil fuel emissions could soon make it impossible for radiocarbon dating to distinguish new materials from artefacts that are hundreds of years old.

Carbon released by burning fossil fuels is diluting radioactive carbon-14 and artificially raising the radiocarbon 'age' of the atmosphere, according to a paper published in the journal Proceedings of the National Academy of Sciences (PNAS).

In radiocarbon dating terms this makes the atmosphere appear older, which is reflected in the tissues of plants taking in CO2 during photosynthesis, and their products such as cottons.

At the rate fossil fuel emissions are currently increasing, by 2050 a new T-shirt would have the same radiocarbon date as a robe worn by William the Conqueror a thousand years earlier.
