“…After preliminary mechanical cleaning of the samples, they were subjected to standard Acid-Base-Acid (ABA) chemical pre-treatment, the purpose of which is to remove fulvic and humic acids and possible carbonates deposited on the dated organic material. Each sample was then charred in a pyrolysis process and then converted to benzene through sequential steps including lithium carbide synthesis, hydrolysis and acetylene trimerisation (Pazdur et al, 2003;Gill et al, 2022). In order to remove radon, which interferes with the measurement of beta activity, the samples were aged in a frozen state for more than 30 days.…”

The present research aimed to determine the age and origin of a 4-m sequence of fluvial deposits located in Siedleszczany on the western side of the Tarnobrzeg Monadnock in the Vistula River valley. Initially, these deposits were thought to be sediments of the overflood (Vistulian) terrace. The study revealed that the sand deposits are relatively young Late Holocene sediments, spanning from the 8th century AD to the 15th–16th centuries AD, and the organic material originated from erosion of older Holocene deposits of various ages. This finding was supported by palynological analysis, which identified, besides Holocene pollen grains, also those from Late Glacial and other Quaternary periods, and even from pre-Quaternary ones. Extreme floods in the Vistula valley may be specified as the origin of the sandy sediments in Siedleszczany. Similar large floods occurred in the past when ice jams blocked the main riverbed, leading to the formation of overflow channels. These floods caused rapid erosion of the flood-plain and deposition of sandy sediments in the sheltered marginal areas of the valley, away from high-velocity flood flows. As a result, the fluvial deposits in Siedleszczany, in the Vistula valley, resemble palaeoflood slackwater deposits observed in various regions worldwide.

“…Nowadays, the demand for biobased materials is increasing rapidly. In many fields, the traditional, fossil carbon containing, petrochemical-based materials, such as fuels and plastics can be replaced by biogenic compounds, not only with the same materials and molecules but with alternatives as well (Bastioli 2001;Gill et al 2022;Palstra and Meijer 2014;Jou et al 2015;Santos et al 2019). The demand for these biobased materials has increased not only at the industrial side but at the side of the customers and consumers as well (Hermann et al 2011;European Commission 2019;Pires et al 2015;Santos et al 2019;Pandey and Singhal 2021;Popp et al 2021).…”

Biobased content analysis is a well-established, analytically independent, standardized method to determine the biobased content of fuels and plastics, based on differences of the specific radiocarbon (14C) activity of fossil and recent biogenic compounds. This biogenic content analysis can be useful for the producers as a quality assurance tool, for the customers as feedback about the truly biobased products and for the control organizations as an independent analytical tool to prove the biological origin. More than 100 commercially available foods, cosmetics, and drug samples have been used for biobased carbon content analysis by accelerator mass spectrometry (AMS) 14C measurement to demonstrate the potential of this technique. Our results show that this measurement technique is a unique tool for the determination of biocontent in foodstuff and medical products. Most of the tested materials were nearly or completely biobased (≥ 98 pMC), and no completely fossil-based final product was detected. The lowest biogenic compound was measured in a vanilla aroma flavor. In 45 of the 102 samples selected a wide range (2–98%) presented fossil-based carbon content. The method can be applied for monitoring raw materials and final products for biobased content in the industry and consumer protection as well.

Radiocarbon (14C) methodology was used to investigate the presence of biocarbon in different bio-based disposable packaging products. Packaging waste contributes to a municipal solid waste, which is increasing environmental concerns and resulting in the enhancement of EU regulations that aim to reduce packaging waste. The 14C amount in samples reflects how much of the biocarbon has been used. In this study, the concentration of 14C was determined in commonly used types of disposable packaging, such as cups, plates, straws, cutlery, and baking paper. Samples were made of materials such as paper, wheat bran, sugarcane, and wood. The mean concentration of the 14C isotope, measured by the accelerator mass spectrometry (AMS) technique, is greater than 100 pMC in all tested samples, indicating that the samples are modern. The relatively high 14C concentration values in the waterproof layer of the sample indicate that bioplastic, rather than plastic, was used in its production. The highest 14C isotope concentration values were measured for samples that used the oldest biomass (wood and paper), and the lowest for products from current crops (sugarcane and wheat bran), which is consistent with the trend of changes in 14C concentration in the biosphere. The study also addresses the problem of heterogeneity and representativeness of subsamples.
