In recent years, with the rapid economic development of Bohai Economic bay area in China, the atmospheric environmental pollution problem has been of wide concern and has attracted great public attention. In this paper, the data of PM₁₀, SO₂, CO, NO₂, O₃ and PM₂.₅ in 12 cities located around the Bohai Bay area of China were collected in 2016. These 12 cities were divided into coastal and non-coastal...
In this study, tri-butyl-phosphate (TBP)-kerosene is used as the extraction solvent to remove phenols from coal gasification wastewater, and the complex mechanism of the extraction is investigated. An effect experiment is conducted to determine the complex structures, the enthalpy change of reaction, and the effect of extraction solvent concentration and temperature on the distribution coefficient...
We used the “space for time substitution” method to test the effects of reclamation history on evolution processes of soil properties and heavy metal concentrations. A total of 129 surface soil samples were collected in a reclamation zone of the Liaohe River Delta, which was divided into three reclaimed zones (1930s, 1960s, and 1990s), marsh, and intertidal flats. Soil metals (Fe, Mn, Cd, Cr, Cu,...
This paper identifies the driving forces of CO₂ emissions from 1990 to 2014 in Xinjiang’s transport sector based on the logarithmic mean divisia index (LMDI) method. Then we introduce the decoupling index to further quantitatively analyze the delinking indicators on the transport sector’s growth and environmental pressures. The results indicate that: 1) CO₂ emissions increased significantly with an...
Nansi Lake, a typical shallow and macrophyte-dominated lake in south Shandong Province, China, has a total surface area of 1,266 km2 and is the largest and most important freshwater reservoir in northern China for the eastern route of the South-North Water Diversion (SNWD) project, in which the water in Yangtze River will be transported more than 1,100 km from Yangzhou to Tianjin and Beijing. A water-level...
Community surveys were performed in 30 forest stands with similar conditions under different management types in forests of northeastern China to study the influence of forest management on plant biodiversity. We evaluated this effect by calculating and analyzing species richness, vegetation structure, and aboveground biomass. Large variations in species composition, vegetation structure, species...
The air pollution index (API) and meteorological parameters in four cities (Harbin, Changchun, Shenyang, and Dalian) in north-eastern China were analyzed in 2001-12, to study the characterization of the API and its influential factors. According to the monitoring data, air pollution is a significant problem in northeastern China, with all four industrial cities heavily polluted, especially Shenyang...
To determine the growth rate and element contents of fingernails in young adults, 109 apparently healthy college students were recruited for determination. As a result, the average growth rate of the left thumb was 3.14±0.63 mm/month with significantly faster rates in male and taller participants. The concentrations for Ca, Na, P, K, and Mg were 701.1±274.8 µg/g, 452.3±353.9 µg/g, 33l.6±119.7 µg/g,...
The Hexi Corridor is the most important area for desert oasis farming in northwestern China. Due to persistent drought and water shortage, sewage irrigation is widely used in this area. Heavy metal pollutants contained in the sewage could remain in the surface layer of agricultural soil and accumulate in plants. Our research used pot experiments to evaluate carrot crop (Daucus carota L.) production,...
