background: hydrocarbons degradation is principally achieved by microorganisms in natural environments. the extent of hydrocarbons biodegradation is mainly conditioned by environmental factors and its success depends on the optimal condition for the crude oil degrading isolates. objectives: the aims of the current study was to isolate and identify crude oil degrading bacterium from surface sedi...

In this study, concentrations of heavy metals in soils around a Zn-smelter in Qeshm island, Iran, are investigated. Calculated geoaccumulation index (Igeo), contamination factor (Cf), and contamination degree (Cdeg) values indicate surface soil contamination by toxic metals (As, Cd, Pb, and Zn). The results also indicate that most contaminated areas are located in the vicinity of the smelter an...

Mangrove ecosystems are of high ecological value and occur in tropical subtropical coastal areas. They consist salt-tolerant woody plants highly complex productive. Here, a novel approach was developed to map disturbances evaluate the status Iranian mangroves based on multispectral WorldView-2 Sentinel-2 remote sensing techniques. A land cover generated that serves as basis assess changes compo...

the importance of inscriptions as the primary sources refer to historical events is undeniable. introducing the shāhugat inscriptions were found near tābaktal village of chāhān district around nikshahr is the purpose of present paper. they refer to the events that occurred in south iran around the end of the 7 th and the beginning of the 8 th centuries ah., a colorful and turbulent period of it...

 The accumulation of heavy metals Pb and Cd in the mangrove, Avicennia marina, was studied on the southern coast of Iran, particularly on and near Qeshm Island in the Persian Gulf. The samples were collected from 7 stations which they were analyzed by flame Atomic absorption spectrophotometer after chemical digestion. Maximum Pb and Cd in leaves are (34.50, 3.52 ppm) and minimum of them are in ...
