Heavy metal concentration of soils affected by Zn-smelter activities in the Qeshm Island, Iran
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...
متن کاملEffectiveness of spectral data reduction in detection of salt-affected soils in a small study area
Data reduction is used to aggregate or amalgamate the large data sets into smaller and manageable information pieces in order to fast and accurate classification of different attributes. However, excessive spatial or spectral data reduction may result in losing or masking important radiometric information. Therefore, we conducted this research to evaluate the effectiveness of the different...
متن کاملOsmolyte dynamics and microbial communities vary in response to osmotic more than matric water deficit gradients in two soils
Sodium chloride and other osmotically active molecules are often applied to microbial cultures or soils to describe microbial responses and adaptation to desiccation in soils. However, salts and other osmolytes may have different effects on microorganisms than matric deficits caused by soil drying. It was thus hypothesized that low matric and osmotic potentials would have different effects on s...
متن کاملCharacterization of Poosti Cheese, a Traditional Raw Sheep Cheese during Ripening: Physicochemical, Microbial and Micro-structural Aspects
Background and Objectives: This study is the first research on the physiochemical characteristics, microbial population and microstructure of Poosti cheese over 90-days of ripening. The main difference between Poosti cheese and other types of traditional cheese is the skin, which is used for its storage. Materials and Methods: Physicochemical characteristics including moisture, salt, pH, acidi...
متن کاملEffects of Heavy Metal Pollution of Apple Orchard Surface Soils Associated with Past Use of Metal-Based Pesticides on Soil Microbial Biomass and Microbial Communities
Apple orchard surface soils in Japan are polluted with copper (Cu), lead (Pb), and arsenic (As) due to long-term use of metal-based pesticides. We investigated the effects of heavy metals accumulated in the surface soils in apple orchards on the microbial biomass and the microbial communities. Soil samples were taken from a chestnut orchard (unpolluted control) and five apple orchards with diff...
