soils around mining sites play a significant role in the transport and control of heavy metals in the environment. therefore, understanding the adsorption properties of soil is essential in solving pollution problems. the objective of this paper was to study zn(ii) adsorption onto sarcheshmeh copper mine soils. the adsorption isotherms of zn(ii) were studied. the langmuir isotherm indicated an ...

Black yeast fungi play critical role in degradation of petroleum polluted soils. Little attention has been paid to the biodiversity of black yeast fungi in Iran. In this paper, diversity of black yeast fungi was studied in petroleum polluted soils in Tabriz and Urmia regions. Soil samples were collected from petroleum polluted areas in vicinity of oil storage tanks in Tabriz and Urmia cities (E...

In the present investigation, physicochemical properties, lime requirement, fertility status and DTPA extractable Zn of soils of Dimapur district of Nagaland were studied. The soils of study area were strong to moderate acidic in reaction with pH ranged from 4.12 to 5.30 and were normal in total soluble salts. The CEC of the soils was quite low, varied from 10.4 to 14.0 cmol (P) kg . The averag...

BACKGROUND Adverse events (AEs) are adverse outcomes caused by medical care. Several studies have indicated that a substantial number of patients experience AEs before or during hospitalization. However, few data describe AEs after hospital discharge. We determined the incidence, severity, preventability and ameliorability of AEs in patients discharged from the general internal medicine service...

abstract phosphorus (p) sorption in soils is a key process governing the availability of p to crops. p sorption characteristics and their relationship to soil properties were determined in twenty-one paired surface soil samples (21 cultivated and 21 adjacent virgin soils) belonging to five soil types: typic calcixerepts, typic haploxerepts, typic endoaquepts, vertic endoaquepts, and vertic calc...

Many countries in the word have loose and unstable soils encompassing a wide range ofgeological materials, which when inundated, may collapse and cause very significant distress to the structure. Stone columns have been used to strengthen such soils; even so, there are still cases where failure has occurred. In this technical note, the process and causes of stone column failure in reinforcing c...
