Plant samples of Cardamine hupingshanesis (Brassicaceae), Ligulariafischeri (Ledeb.) turcz (Steraceae) and their underlying top sediments were collected from selenium (Se) mine drainage areas in Enshi, China. Concentrations total Se measured using Hydride Generation-Atomic Fluorescence Spectrometry (HG-AFS) speciation determined liquid chromatography/UV irradiation-hydride generation-atomic fluorescence spectrometry (LC-UV-HG-AFS). The results showed that C. could accumulate to 239±201 mg/kg...

Most cities in China are experiencing severe air pollution due to rapid economic development and accelerated urbanization. Long-term data with high temporal spatial resolutions needed support research into physical chemical processes that affect quality, the corresponding health risks. For first time, on PM10, PM2.5, SO2, NO2, O3 CO concentrations 23 ambient quality automatic monitoring stations routine meteorological were collected between January 2014 December 2016 determine variation...

In order to clarify the total selenium (Se) content and species of Se in soils Dashan Region, a typical Se-enriched area China, 69 soil samples with different land-use purposes were collected, concentrations Se, water-soluble exchangeable acid-soluble organic-bound residual physical chemical properties these investigated. The ranged between 0.31 7.65 mg kg−1 (dry weight). water-soluble, exchangeable, acid-soluble, forms 7.71–26.8 μg kg−1, 24.7–93.3 112–1430 26–765 1300–5330 respectively....

Regional land use transitions driven by the adaptive reconciliation of existing conflict with socioeconomic development can lead to positive economic effects as well new conflict. Although research on transition has progressed considerably, limited studies have explored spatiotemporal dynamic pattern during period. Previous evaluation approaches that mainly focus status or potential lack intensity process. A spatially explicit framework directly examines three aspects conflict, namely,...

Cereals and soybeans are the main food sources for majority of Chinese. This study evaluated effects four common cooking methods including steaming, boiling, frying, milking on selenium (Se) content speciation in seven bio-fortified cereals samples. The Se concentrations selected samples ranged from 0.91 to 110.8 mg/kg selenomethionine (SeMet) was detected be species. Total loss less than 8.1% during processes except milking, while 49.1% total lost soybean soy milk due high level residuals....

Abstract This paper explores the influence of Confucian culture on firms' emissions. We measure during Ming and Qing dynasties using density jinshi in that region test causal relationship between emissions Annual Survey Industrial Firms (ASIF) China's Environmental Statistics Database (CESD) from 1998 to 2013. Our research reveals regions with a stronger cultural have significant reduction pollution their firms. Further analysis demonstrates government strong attaches more importance...

Abstract Background Dietary rationality and health concept have certain influence on individual level. This study aims to explore the characteristics existing problems of Chinese residents’ behaviors from both macro micro perspectives, feasibility realization path Healthy China strategy. Methods We utilized regression models evaluate correlation between diet risk disease causes death. By use linear analysis model, we distinguished impact each dimension literacy index at Then, explored...

Improving the ecological well-being performance (EWP) of natural resources and environmental consumption in relation to human well-being, within boundary, is necessary for sustainable development. This study used Super-SBM model measure urban EWP agglomeration middle reaches Yangtze River (MRYRUA) 2020. The spatial differentiation characteristics MRYRUA were identified. heterogeneity direction size influencing factors at different hierarchy (UH) levels was empirically tested by establishing...

With the increasingly serious environmental problems, coordinating relationship between environment and economic development has become a crucial task for developing countries, especially China. This paper studies role of eco-industrial parks (EIPs) in emissions carbon dioxide sulfur China with difference-in-difference (DID) approach by focusing on entire process EIPs’ establishment—upgrading provincial zones (DZs) to national DZs then transforming into EIPs. Besides, we examined...

Exploring carbon emission effects based on the evolution of residents' dietary structure to achieve neutrality goal and mitigate climate change is an important task. This study took China as research object (data excluding Hong Kong, Macao Taiwan) used coefficient method quantitatively measure food emissions from 1987–2020, then analyzed under structure. The results showed that during period, Chinese gradually changed a high-carbon consumption pattern. urban residents developed balanced one,...

The imbalanced regional development of higher vocational education, particularly the disparity between supply and demand educational resources, has emerged as primary factor impeding provision high-quality education in China during establishment a universal system. Based on 1,482 institutions recognized by Ministry Education 2021 research objects, was explored from perspective using entropy weight TOPSIS method coupling coordination degree model. It found that China's were mainly located...

Along with the rapid development of urbanization and industrialization, carrying capacity territorial space has been confronted a serious crisis. Faced many uncertain risks unknown disruptions, it is important to proactively address uncertainty future developments in planning improve spatial resilience (TSR). Based on connotation TSR, we build an assessment framework for TSR containing urban, agricultural ecological from three dimensions, including element, structure function. Using variety...
