“…coupling of gas chromatography with AMS systems. By a combination of gas chromatographs, which select and separate necessary amounts of specific compounds, with an AMS which perform mass isotope analysis, it has been possible to open new windows for new isotope research [ 98 – 101 ]. This trend is having, however, more general applications, e.g.…”

Recent developments in radiometric and mass spectrometry technologies have been associated in the radiometric sector mainly with underground operations of large volume Ge detectors, while the mass-spectrometry sector, represented mainly by accelerator mass spectrometry and inductively coupled plasma mass spectrometry has become the most sensitive technique for ultra-low-level analyses of long-lived radionuclides. These new developments have had great impact on investigations of rare nuclear processes and applications of radionuclides in environmental, life and space sciences. New scientific investigations have been carried out therefore which have not been possible before either because of lack of sensitivity or required large sample size.

“…The aim of the present study is to estimate carbon consumption and differential utilization by Pseudomonas putida bacteria. Our interest in microbiological studies of sediments has been triggered by evaluation of organic carbon sources in Baltic Sea sediments in connection with dumping of chemical warfare agents (CWA) in the Gotland Deep after the Second World War (Lujaniene et al 2017). Pseudomonas putida is one of the bacteria that is expected to be responsible for degradation of CWA (Medvedeva et al 2009) that were produced before the World War II from raw fossil materials, such as petroleum, natural gas, petroleum distillates, and coal (Franke 1973).…”

Distributions of Δ14CTOC studied in bottom sediments collected during 2011–2016 in the Curonian Lagoon and in the open Baltic Sea indicated wide variations of Δ14CTOC values. Laboratory experiments on differential carbon utilization by Pseudomonas putida isolated from bottom sediments were carried out for better understanding of impacts of different sources on Δ14CTOC variations. Preferential glucose uptake (up to 80%) as a carbon source and a rather low (2–10%) inorganic carbon incorporation was found in media with diesel fuel. Pseudomonas putida a specific biomarker analyzed in biomass cultivated on the media with different carbon sources has been used to characterize microbial communities responsible for degradation of organic substances in bottom sediments. Large 14C depletions observed in sediments collected in the Gotland Deep of the Baltic Sea may indicate leakage from dumped chemical weapons.
