To get representative soil samples, a sampling method was verified for crop fields in the vicinity of abandoned mine sites. Application of appropriate sampling or analytical methods is very important as it affects the costs, time, and accuracy of the refined investigation of soil contamination. Two-time sampling for each crop field was conducted to verify the reproducibility of a zigzag method ...

The aim of this study was to determine the extent of metal pollutions and the identification of their major sources in the vicinity of the Sangan iron mine occurring in NE Iran. Soil samples were collected from the vicinity of the mine site and analyzed for heavy metals. In addition, the chemical speciation of these metals was investigated by means of the sequential extraction procedure. The st...

The residues from the extraction of lead/zinc (Pb/Zn) ores of most Pb/Zn mines are permanently stored in tailings ponds, which require revegetation to reduce their environmental impact. This can only be done if the main constraints on plant establishment are evaluated. This can readily be done by field and greenhouse studies. To test this, the properties of different tailings from Lechang Pb/Zn...

nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (anfo) explosive at the sungun surface mine, located in the northwest of iran. the pollutants were monitored during some blasting operations at the mine. it was concluded that the gases and dust clouds initially went up to the ...

Dispersion of lead (Pb) in mine wastes was simulated for reproducing Pb contamination soil Kabwe District, Zambia. Local weather data year 2019 were monitored situ and used the simulations. The plume model, weak puff no model adopted calculation dispersion under different wind conditions. results showed that from directly affected by directions speeds dry season, although it not appreciably rai...

The study of Technosols development, spatial distribution and physicochemical characteristics is becoming more important in the Anthropocene Era. aim present was to assess soil features potential heavy metal release risk soils developed on different mine tailing types after waste disposal derived from mining activity Central Italy. Soils were analyzed for their morphological, physical chemical ...

sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of iran and most probably the second largest copper mine in the world. this mine is located in the seismotectonic zone of central-iran, and 23 km away from the 150 km long rafsanjan active fault.in this study the vulnerability of the west wall of the...

Human activities on the Earth's surface change the landscape of natural ecosystems. Mining practices are one of the most severe human activities, drastically altering the chemical, physical and biological properties of the soil environment. Bacterial communities in soil play an important role in the maintenance of ecological relationships. This work shows bacterial diversity, metabolic repertoi...

The geochemical characterization of the mine deposits and soils in metal mining areas is essential order to develop an effective reclamation strategy. determination total potentially toxic element (PTE) content, together with application chemical extraction procedures, can give insight into behavior contaminants after different solutions, as well identify where urgent action needed. This work p...
