Sihailongwan Maar Lake, located in Northeast China, is a candidate Global boundary Stratotype Section and Point (GSSP) for demarcation of the Anthropocene. The lake’s varved sediments are formed by alternating allogenic atmospheric inputs authigenic lake processes store record environmental human impacts at continental-global scale. Varve counting radiometric dating provided precise annual-resolution sediment chronology site. Time series records radioactive ( 239,240 Pu, 129 I soot 14 C),...
There has been a sharp rise in the extent and scale of human activities since mid-20th century, termed "Great Acceleration", nuclear are one defining technological processes for this period. 239,240Pu released by atmospheric weapons tests provides an ideal chronostratigraphic marker labeling change due to its global fallout feature, temporal mutation, long half-lives. However, accumulation dynamics plutonium from deposition preservation sediment is still controversial. Three cores collected...
Atmospheric iodine isotopes have a significant impact on climate change and human health. However, the sources, transport pathways, transfer processes of atmospheric are still not well understood. Tree rings spruce collected from east edge Qinghai-Tibet Plateau were analyzed for (127I 129I). The results show that levels temporal variation recorded in tree rings, stable concentrations increased three times 1960 to 2015, reflecting releases atmosphere past decades due activities. anthropogenic...
Human impacts on Earth's atmosphere, hydrosphere, litosphere and biosphere are so significant as to naming a new geological epoch, the Anthropocene. Lakes their biota highly sensitive environmental changes. Among aquatic organisms, microbial eukaryotes play fundamental roles associated with lake ecosystem functioning, food webs, nutrient cycling, pollutant degradation. However, response of eukaryotic community during Anthropocene changes in conditions remain poorly understood. Here, we...
As the most important plutonium isotopes, 238Pu, 239Pu, 240Pu, and 241Pu are normally measured by two to three techniques, which tedious, time-consuming, not suitable for rapid analysis in emergency situations. Recently, ICP-MS has become a competitive technique measurement of 241Pu. However, is difficult measure 238Pu due serious isobaric interference 238U. This work reports analytical method solve this problem simultaneous determination using triple-quadrupole inductively coupled plasma...
Due to the high radiotoxicity in concentrations, plutonium isotopes have drawn attentions consideration of radiation risk, their sources, level, environmental behaviors, including deposition, retention and migration behaviors. However, such research Qinghai-Tibet Plateau is still missing, where deemed as an sensitive area. 239,240Pu surface soil collected from were determined for first time this work. The concentrations are range 0.0176-1.95 Bq/kg, falling into reported ranges background...
Abstract Anthropogenic‐driven environmental change, including current climate warming, has influenced lake ecosystems globally during the Anthropocene. Phytoplankton are important indicators of changes in lakes and play a fundamental role maintaining functioning stability these ecosystems. However, extent to which phytoplankton were affected by anthropogenic or climatic forces Anthropocene remains unclear. Here, we investigated 160‐yr‐long dynamics community (cyanobacteria eukaryotic...
Abstract Human brain demonstrates amazing readiness for speech and language learning at birth, but the auditory development preceding such remains unknown. Cochlear implanted (CI) children ( n = 67; mean age 2.77 year ± 1.31 SD; 28 females) with prelingual deafness provide a unique opportunity to study this stage. Using functional near‐infrared spectroscopy, it was revealed that of CI irresponsive sounds hearing onset. With increasing experiences up 32 months, demonstrated function, region...
The unsourced oil contamination on the coast of Bohai Sea has recently attracted scholars to study formation sunken and suspended oils (SSO) from slicks sea surface. In this research, batch experiments have been conducted time-scale effect different concentrations sediments using three (Oman crude oil, Merey 380# fuel oil) two (sand silt) at temperatures. results showed that formed quickly within mixing time reached a maximum equilibrium time, te, te had wide range variation with sediment...
An analytical method based on triple quadrupole inductively coupled plasma mass spectrometry (ICP-MS/MS) was developed for simultaneous determination of femtogram levels 237Np, 239Pu, and 240Pu in environmental samples. By carefully controlling the valence states Np Pu entire separation procedure using a simple single extraction chromatographic column (TK200), consistent behavior achieved, allowing reliable application 242Pu as chemical yield tracer 240Pu. A high decontamination factor 3.2 ×...
The research on geochemical behaviors of iodine is significant for deep understanding the source and distribution earth.However, as one most important sources, ocean emissions relative transport pathways iodine, well preservation after deposition are still not known, especially in arid areas central Asia.A peat sediment core collected nearby Barkol Lake from northwest China was analyzed isotopes ( 127 I 129 I).The observed high concentration top 2 cm indicated a accumulation surface oxic...
