Exploration of social determinants of health and prostate cancer prevalence in the US
Objective Social determinants of health (SDoH) are increasingly recognized as key factors in addressing health inequities. This study aimed to explore the association between SDoH and risk of prostate cancer (PCa). Methods We analyzed data from the National Health and Nutrition Examination Survey 2003–2010. PCa diagnosis was based on self-reported questionnaires, while highly-probable PCa was assessed using prostate-specific antigen levels. Multi…
Tracing the source of dissolved organic carbon in rivers by carbon isotope (Δ14C-δ13C)
The cycling of carbon in riverine systems is a critical component of global carbon cycle research. However, the sources and performances of riverine carbon in the Qinling Mountains, a pivotal hydrological nexus in China, remain poorly understood. This study investigates the seasonal variations of dissolved organic carbon (DOC) concentration in the Tianyu River within the Qinling Mountains. By utilizing a combination of carbon isotopic signatures …
Recent Progress in Atmospheric Fossil Fuel Co 2 Trends Traced by Radiocarbon in China
It is important to know how much of the increased atmospheric CO 2 is derived from fossil fuel emissions. Here, we review the progress in atmospheric fossil fuel CO 2 (CO 2 ff ) tracing over recent years by measurement of Δ 14 C in Chinese cities. In this paper we make progress by expanding the analysis from some locations to more regional views, by combining observations with modeling, and by making a preliminary comparison of observation-derive…
C Geochronology and Radiocarbon Reservoir Effect of Reviewed Lakes Study in China
Lacustrine sediments are important archives for paleoclimate research, but there are evident carbon reservoir effects. Radiocarbon ( 14 C) ages of lake sediments must be corrected for these effects before applying them to paleoclimate research. The authors review the lacustrine research from the last 20 years from different climatic regions in China, and systematically investigate the 14 C age and correction methods used in the studies of 81 lake…
C Chronostratigraphy for Qinghai Lake in China
Radiocarbon accelerator mass spectrometry (AMS) techniques were used to date total organic carbon and plant seeds in the lFs core sequence (36°48′N, 100°08′E) from Qinghai Lake, China. This core was drilled ∼18 m into Qinghai Lake sediments as part of an international cooperative research project, “Scientific Drilling at Qinghai Lake in the Northeastern Tibetan Plateau: High-Resolution Paleoenvironmental Records of Eastern Asia Linked to Global C…
C Dating of Soil Organic Carbon (SOC) In Loess-Paleosol Using Sequential Pyrolysis and Accelerator Mass Spectrometry (AMS)
The chemical extraction of soil organic carbon (SOC) fractions from soils often does not produce satisfactory results for radiocarbon dating. In this study, a sequential pyrolysis technique was investigated. The soil was pyrolyzed at temperatures of 200, 400, 600, and 800 °C to partition organic carbon into pyrolytic volatile (Py-V) and pyrolytic residue (Py-R) fractions. The preliminary results show that the 14 C dates of both fractions become p…
Interplay between the Westerlies and Asian monsoon recorded in Lake Qinghai sediments since 32 ka
Two atmospheric circulation systems, the mid-latitude Westerlies and the Asian summer monsoon (ASM), play key roles in northern-hemisphere climatic changes. However, the variability of the Westerlies in Asia and their relationship to the ASM remain unclear. Here, we present the longest and highest-resolution drill core from Lake Qinghai on the northeastern Tibetan Plateau (TP), which uniquely records the variability of both the Westerlies and the…
High-Level 14 C Contamination and Recovery at Xi'an AMS Center
A sample with a radiocarbon concentration estimated to be greater than 10 5 times Modern was inadvertently graphitized and measured in the Xi'an AMS system last year. Both the sample preparation lines and the ion source system were seriously contaminated and a series of cleaning procedures were carried out to remove the contamination from them. After repeated and careful cleaning as well as continuous flushing with dead CO 2 gas, both systems hav…

Is There a Time-Transgressive Holocene Optimum in the East Asian Monsoon Area
We have carried out a multiproxy analysis of high-resolution eutrophic peat/mud, sand dune, and loess/paleosol sequences covering the Holocene period in both southern and northern China, in order to test the hypothesis of a time-transgressive Holocene optimum in the East Asian monsoon area (An et al. 2000). Samples were radiocarbon dated to establish the chronology. Our results indicate that the Holocene optimum occurred between ∼10,000–5000 cal …
High-resolution evidence from southern China of an early holocene optimum and a mid-Holocene dry event during the Past 18,000 Years
Computer models suggest that the Holocene Optimum for East Asian summer monsoon precipitation occurred at different times in different regions of China. Previous studies indicate that this time-transgressive Holocene Optimum should have been experienced about 3000 yr ago in southern China. In this study we describe a section which allows us to test this timing directly. We have closely examined high-resolution eutrophic peat/mud sequences coverin…
