Background and Objective: Urban and industrial development has increased concentration of heavy metals in the environment. The goal of this study was to assess the impact of Kerman steel complex on their surrounding soil by heavy metals. Materials and Methods: This study was a snapshot and its type was descriptive-analytical research. Heavy metals contents from 60 soil samples (top soil, 0-1...
altogether 20 groundwater samples were collected around the lakan pb and zn mine in iran. samples were analyzed for 8 constituents including fe, pb, hg, mn, zn, cn, so4 and cl using standard method. the results show that the average concentrations of constituents were 0.01, 0.60, 0.10, 0.01, 0.40, 35, 0.01 and 5.95 mg/kg for fe, mn, pb, zn, hg, so4, cn and cl, respectively. the computed contami...

a study of substantial anthropogenic related pollution in the coastal samut prakarn province (thailand) was carried out focusing on the bang pu nature reserve (remnant mangrove wetland) using a remote sensing (geospatial) technique. statistical regression models were developed between biochemical parameters of sample point and related reflectance data obtained from satellite imagery (landsat...
eighteen kilometers long coastal stretch from the new mangalore port in the north totalapadi in the south has been studied in order to understand shoreline changes and erosion/ accretion patterns that have taken place due to the natural processes and anthropogenic activities. shoreline changes and quantification of beach erosion/accretion were made using the survey of india topomap, multidated ...
Heavy metals in dust can directly enter to the human body through ingestion and inhalation. They can pollute the water and soil resources via atmospheric precipitation and accumulate in the plant tissues and then enter human body through water and food. This research aimed to study the heavy metals concentration in dust in Kermanshah province and to identify their sources. 49 samples of dust we...
Scientific Objectives , Measurement Needs , and Challenges Motivating the PARAGON Aerosol Initiative
OCTOBER 2004 AMERICAN METEOROLOGICAL SOCIETY | T he Progressive Aerosol Retrieval and Assimilation Global Observing Network (PARAGON) concept (Diner et al. 2004) envisions a coordinated and systematic approach for dramatically improving our understanding of aerosol climate impacts and environmental interactions. Among its scientific motivations is the need to establish, with great confidence, t...
