Reclamation under the strict requirements of the federal Surface Mining Control and Reclamation Act of 1977 requires a high level of knowledge of plant growth r e q u i r e m e n t s in r e l a t i o n to geochemical factors on each mine site. A desirable reclamation goal would be to consider all feasible alternatives for creating productive soils and attractive landscapes. The raw materials fo...

The scale of the industrial chain for construction waste reclamation in China is still at a small magnitude with a relatively slow development rate, yet to form an industrial chain that is mature. With the industrial chain theory, this paper takes Guangzhou as an example to construct a simulation model of the scale of industrial chain of construction waste reclamation based on system dynamics. ...

Significant alteration in the microbial community can occur across reclamation areas suffering subsidence from mining. A reclamation site undergoing fertilization practices and an adjacent coal-excavated subsidence site (sites A and B, respectively) were examined to characterize the bacterial diversity using 454 high-throughput 16S rDNA sequencing. The dominant taxonomic groups in both the site...

Over the past six decades, coastal wetlands in China have experienced rapid and extensive agricultural reclamation. In the context of saline conditions, long-term effect of cultivation after reclamation on soil chemical properties has not been well understood. We studied this issue using a case of approximately 60-years cultivation of a coastal saline marsh in Bohai Rim, northern China. The res...

Coal mining is inevitable for economic growth of a country, but at the same time deteriorates the quality of the environment. Open cast mine, especially affects the top soil most negatively. In the present study, soil samples from three representative areas of mining viz proposed, operational and abandoned sites from Charhi and Kuju of Jharkhand were collected and analysed for physicochemical p...

The age of Anthropocene makes it imperative that we find ways to tackle pollution and stay within planetary boundaries limits, one these is nutrients availability. From a point view, the release new reactive nitrogen should be 25% current level, equal yearly about 35 million tons. Instead discharging N- P-rich wastewater into coastal inland waters, use same microalgae growth for useful purposes...

In this study, 16 seasonal fly ash samples of municipal solid waste incinerator (MSWI) were collected in from waste-to energy power plant Cantho city to analysis the physical properties and heavy metals content. The results showed that are very alkaline with porous spherical shape, particle size 1-100 µm. analytical disclosed these samples, Zn, Pb, Al, Fe Cr found at high content range 0.36-19....

One solution to current water scarcity is the reuse of treated wastewater. Water systems have be examined as a whole, including efficacy water-reclamation treatments and operation steps from wastewater inlet into WWTP irrigation endpoint, irrigated crop. In this study, monitoring human enteric viruses coliphages were assessed in two reused systems. The presence hepatitis A virus (HAV) norovirus...

It is our great honor to edit this special issue of Environmental Geochemistry and Health (EGAH), especially with the special theme of mine reclamation and suitable management for heavy metals. This issue has been made up with the extended works of oral or poster presentations that were given at the 2009 International Symposium on Mine Reclamation held cooperatively by the Korea Mine Reclamatio...

The growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. Various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (MD) process, as a promising separation technology, has recently gained more attention. The MD process is a non-isothermal membrane-based separati...
