Some scientists consider the loss of the American chestnut from forests in the eastern United States as one of the greatest forest ecological disasters in the 20th century. The American Chestnut Foundation has been attempting to restore chestnut by backcrossing blight-resistant Chinese chestnut to American chestnut and selecting those strains with blight resistance. Third-generation backcross s...

the morphological diversity of arbuscular mycorrhizal fungi (amf) at the anguran zn and pb mining region (zanjan province, iran) were studied along a transect from the mine to 4500 m away. within each plot, a composite sample of root and rhizospheric soil from a dominant indigenous plant was collected. the soil samples were analyzed for their physico-chemical characteristics. spores were extrac...

The adsorption and desorption characteristics of cadmium (Cd) in uncontaminated soils have been investigated numerous studies. However, similar studies on Cd-polluted from different sources, which exhibit complex physicochemical internal interactions between Cd the soil particles, are scarce. Therefore, order to elucidate polluted soils, six representative Cd-contaminated paddy samples were col...

Landowners in the Appalachian region are becoming increasingly interested in restoring the native hardwood forest on mined land after reclamation. Trees are usually planted in topsoil substitutes consisting of blasted rock strata from the geologic profile. Reforestation attempts using native hardwoods have often been unsuccessful due to the highly variable nature of the physical, chemical, and ...

Reclaimed mine soils (RMS) which develop on post-mining sites play significant role in Carbon sequestration in new ecosystems, especially in local range on areas disturbed by human activity. This study presents the potential for Carbon sequestration in RMS developing on 3 post surface mining areas in Poland (Central Europe) reforested with Scots pine (Pinus sylvestris L). Research was conducted...

OBJECTIVES Asbestos is associated with South African diamond mines due to the nature of kimberlite and the location of the diamond mines in relation to asbestos deposits. Very little is known about the health risks in the diamond mining industry. The objective of this study was to explore the possibility of asbestos exposure during the process of diamond mining. METHODS Scanning electron micr...

Through the years, mining and beneficiation processes produces large amounts of As-rich mine wastes laid up in huge tailings and open-air impoundments (Barroca Grande and Rio tailings) that are the main source of pollution in the surrounding area once they are exposed to the weathering conditions leading to the formation of AMD and consequently to the contamination of the surrounding environmen...

Mine water contains trace heavy metals which are some essential elements in high concentrations causing the pollution of nearby bodies, related ground waters and soils degradation. The aim study is to identify quantify present different mine samples their level toxicity. Digestion technique was employed pretreat wastewater before analysis. Physicochemical analysis conducted for pH, electrical c...
