Distribution of 137Cs Radionuclide in Industrial Wastes Effluents of Gresik, East Java, Indonesia

Atom Indonesia, 2015
The distribution of anthropogenic radionuclides 137Cs was measured from industrial waste effluent of Gresik to Gresik Sea in east Java, Indonesia. The activity of 37Cs detected at all stations was much lower than in northeast Japan both before and after ...

Long‐Term Biodiversity–Stability Relationship in Temperate Mountain Forests

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Theories on ecological stability lack the long‐term observational data necessary to comprehend the dynamics of durable and complex ecosystems like forests; consequently, the influence of biodiversity on ecosystem stability remains predominantly unexplained.

Sedimentary DNA and Fossil Archives Reveal Long‐Term Phytoplankton Shifts and Their Biogeochemical Influence in a Subtropical Lake

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Understanding long‐term phytoplankton community dynamics is essential for assessing ecological resilience and informing lake management under global change. However, centennial‐scale patterns of phytoplankton dynamics remain poorly resolved due to the limited taxonomic resolution of traditional fossil‐based paleoecological approaches.

Substantial Accumulation of Chemically Oxidizable Organic Carbon in Continental Margin Sediments

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The balance between organic carbon (OC) sequestration and oxidation regulates the oceanic carbon cycle, and OC reactivity determines its susceptibility to remineralization or long‐term burial. However, the stability of sedimentary OC on continental margins remains poorly understood.

东北黑土中137Cs背景值研究

Shuitu Baochi Xuebao, 2004
通过测定东北黑土背景点样品中137Cs活度,探讨了土壤剖面中137Cs的分布特征,对因风蚀造成背景点土壤表层137Cs的沉积进行了校正,得出了黑土的137Cs背景值,为水蚀风蚀两相侵蚀地区土壤137Cs背景值的确定提供了新思路。结果表明:黑土背景点土壤剖面中137Cs比活度的分布呈指数型,其拟合方程为Cs=76.744e-0.2566h,相关系数达到0.994。剖面中75.7%的137Cs分布在0～5cm的表层中,92.5%的137Cs分布在0～10cm的土壤上层;黑土的137Cs背景值为2463 ...

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

Advanced Healthcare Materials, Volume 15, Issue 27, 17 July 2026.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...
