Updating the dual C and O isotope-Gas-exchange model: A concept to understand plant responses to the environment and its implications for tree rings.
Publication Type: Academic Journal
Source(s): Plant, cell & environment [Plant Cell Environ] 2023 Sep; Vol. 46 (9), pp. 2606-2627. Date of Electronic Publication: 2023 Jun 07.
Abstract: The combined study of carbon (C) and oxygen (O) isotopes in plant organic matter has emerged as a powerful tool for understanding plant functional responses to environmental change. The approach relies on established relationships between leaf gas exch...
Multiple-biomarkers show the importance of blue carbon to commercially important fishery species.
Publication Type: Academic Journal
Source(s): The Science of the total environment [Sci Total Environ] 2023 Jul 10; Vol. 881, pp. 163162. Date of Electronic Publication: 2023 Apr 07.
Abstract: Coastal blue carbon ecosystems (BCE) support nearshore food webs and provide habitat for many commercially important fish and crustacean species. However, the complex links between catchment vegetation and the carbon food-base of estuarine systems are ...
Carbon Dioxide Radical Anion by Photoinduced Equilibration between Formate Salts and [ 11 C, 13 C, 14 C]CO 2 : Application to Carbon Isotope Radiolabeling.

Abstract: The need for carbon-labeled radiotracers is increasingly higher in drug discovery and development (carbon-14, β - , t = 5730 years) as well as in positron emission tomography (PET) for in vivo molecular imaging applications (carbon-11, β 1/2 = 5730 yea...
Characteristics of dissolved black carbon in riverine surface microlayer.
Publication Type: Academic Journal
Source(s): Marine pollution bulletin [Mar Pollut Bull] 2023 Sep; Vol. 194 (Pt B), pp. 115301. Date of Electronic Publication: 2023 Jul 19.
Abstract: Black carbon (BC) is produced by the incomplete combustion of biomass and fossil fuels. The dissolved form of BC (DBC), which is transported through rivers into the oceans, is of great significance for the carbon cycling on the planet due to its refrac...
Preliminary investigation of soil organic carbon distribution and turnover patterns, and potential pollution sources in and around a typical coking plant in North China.
Publication Type: Academic Journal
Source(s): Environmental research [Environ Res] 2023 Jul 01; Vol. 228, pp. 115845. Date of Electronic Publication: 2023 Apr 05.
Abstract: The variation characteristics of soil organic carbon (SOC) in and around the coking plant area are still unclear. In this work, the concentration and stable carbon isotope composition of SOC in coke plant soils were investigated to preliminarily identi...
Particulate organic carbon potentially increases methane emissions from oxic water of eutrophic lakes.
Publication Type: Academic Journal
Source(s): The Science of the total environment [Sci Total Environ] 2023 Sep 01; Vol. 889, pp. 164339. Date of Electronic Publication: 2023 May 20.
Abstract: Lakes are hot spots for methane (CH 4 ) emissions and particulate organic carbon (POC) production, which describes the methane paradox phenomenon. However, the current understanding of the source of POC and its effect on CH 4 emissions during eutrophic...
Assessment of stable carbon isotope 13 С/ 12 С ratio in phthalates from surface waters using HPLC-HRMS-TOF approach.
Publication Type: Academic Journal
Source(s): Environmental science and pollution research international [Environ Sci Pollut Res Int] 2023 Aug; Vol. 30 (37), pp. 87734-87742. Date of Electronic Publication: 2023 Jul 11.
Abstract: A method for estimating the ratio of stable carbon isotopes 13 С/ 12 С in the composition of phthalates from surface water at a trace concentration level is proposed. It is based on the concentration of hydrophobic components of water using an analytic...
Radio- and stable carbon isotope analysis reveals minimal assimilation of petrogenic carbon into an oligotrophic freshwater food web after experimental spills of diluted bitumen.
Publication Type: Academic Journal
Source(s): Chemosphere [Chemosphere] 2023 Jul; Vol. 329, pp. 138608. Date of Electronic Publication: 2023 Apr 05.
Abstract: Following an oil spill into water, bacteria can biodegrade petroleum hydrocarbons which could lead to petrogenic carbon assimilation by aquatic biota. We used changes in the isotope ratios of radio- (Δ 14 C) and stable (δ 13 C) carbon to examine the po...
