The article presents materials on identifying possible changes in oil-bearing and oil-polluted soils of Absheron peninsula using satellite data GIS technologies. state degraded polluted with oil oily wastes, was analyzed as well the territories where 2014, 2017 2020 recreational activities were carried out. Multispectral images landsat-8 used to detect these territories. received primary result...
The explosives, in manufacturing, transporting and using at military installations, caused to pollution of ground and sub-ground waters, soils and sediments. Soil is posed as a relationship between water, weather and plants and animals existence of a zone. Therefore, soil health is a necessary matter. So, in order to suppression from environmental issues and human detriment, polluted soil impro...
A series of batch tests were conducted to investigate the relative desorption potential of mercury from kaolin and glacial till soils under the effect of three extractant agents, namely, KI, NaEDTA and NaCl (all of them with a concentration of 0.1 M). These tests were conducted under different pH conditions (within a pH range between 2 and 12). Also batch tests using deionized water were perfor...
Polyacrylamide (PAM) is a water-soluble polymer with strong cohesiveness and water absorption capacity, it has been widely used to modify soil structural stability. However, little information available on the impact of PAM application aggregate-breaking process purple soils in hilly areas southwestern China. Therefore, current study aimed examine influence aggregate stability terms different b...
Soil erodibility and gully erosion and their expansion occur under geological formation and soil characteristics. This study aims to find the rate of soil and formation effects on gully erosion in Seifabad watershed. To that end, aerial and field work were used together to determine the rate & expansion of 17 gullies in 12 years' period from 1997 to 2009. The soils were sampled for each gully ...
Overtopping, internal erosion, and piping are the main causes of accidents and failures of embankments for dams, lagoons, and levees. A key parameter in the failure of these structures is the erodibility of the soil materials used in construction of the embankments. The soil materials are typically constructed based on compaction specifications. The jet erosion test (JET) has been developed to ...
Phytoremediation is a new, in-situ and emerging remediation technology for contaminated soils. This technology, compared to other methods, is a sustainable, natural, relatively cheap and applicable to large scale area. Modeling phytoremediation provides quantitative insight for the governing process as well as for managers to assess the remediated sites. The objective of this study was to intro...
Establishment of arbuscular mycorrhizal symbiosis in plant roots can affect plant physiological and morphological characteristics and may induce tolerance to heavy metals in plants grown in polluted soils; therefore, it can play an important role in phytoremediation. In present study, to investigate the effect of mycorrhizae on alfalfa growth and Pb uptake, a factorial experiment was designed w...
Surface soils collected from Taizhou, a typical e-waste recycling area in Southeast China, were analyzed for the residues of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) by using microwave-assisted extraction and gas chromatography -mass spectrometry (GC-MS). The total concentrations of 16 PAHs in US EPA's priority list (ΣPAHs),...
