Background & Objectives: Dust storms happening frequently in arid and semiarid regions of the world carry huge amount of particulate matters hence, these are recognized as one of the most important environmental issues at regional and international scales. This study aimed to evaluate heavy metals laden dustfall particles in Sanandaj, Khoramabad, and Andimeshk cities, West Iran. Materials & Met...
The spatial and temporal distributions, contamination evaluation, source apportionment of Cu, Zn, As, Pb, Cd, Cr in the sediments Hulun Lake were explored this work. pollution characteristics six heavy metals assessed by single factor index (PI) geo-accumulation (Igeo). sources surface analyzed positive definite matrix factorization (PMF) Pearson correlation analysis. sedimentary records core r...
Background & objectives: Heavy metals in urban parks are one of the most important indicators of urban pollution, as children playing in the park can readily be affected. This research was conducted to evaluate the environmental pollution of some heavy metals in Ahvaz parks. Methods: To this end, 26 sampling stations were selected from 20 parks in Ahvaz city and the soil samples were analyzed b...
Background and Objective: Street dust is considered as one of the important sources of particulate matters and heavy metals in the atmosphere. The goal of this study was to assess the heavy metals pollution in street dust of Tehran and evaluate their ecological risk. Materials and Methods: The sampling of street dust was carried out in two areas at the east and west of Tehran. After preparatio...
The aim of our study is to determine the hyperaccumulatory properties by examining heavy metal accumulation (Co, Ni, Fe) in endemic Anchusa leptophlla subsp. tomentosa, Alyssum pateri pateri, Glaucium acutidentatum and non Erysimum uncinatifolium species collected from a copper mining area Elazığ Maden district. All are hyperaccumulator according their Bioconcentration Factor (BCF) values Co el...
The contamination characteristics and health risk of barium (Ba), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), vanadium (V), zinc (Zn), arsenic (As), mercury (Hg), and cadmium (Cd) in samples of dust gathered from squares and parks of Baotou city, an industrial city situated in a semi-arid location of the northwest China were investigated. The contents of Ba,...
The main objective of the present study is to assess level contamination, source identification, and health risk assessment heavy metals in industrial soils Aurangabad. A total 15 Soil samples were collected with a sampling density 3–5 composite soil from 0–10 cm surface soil, analyzed (Ni, Pb, Cd, Zn, Cr, Mn, Fe, Cu) using atomic absorption spectroscopy. geographical information system (GIS) t...
We assessed the spatial and temporal variations of pollution indicators and geochemical and trace metal parameters (23 in total) from water and sediment (144 samples) of three different eco-niches (beach, fishing harbor, and estuary) in larger coastal cities of southern India (Cuddalore and Pondicherry) for one year. A total of 120 marine Pseudomonas isolates were challenged against different c...
pollution of water and soils by heavy metals is an emerging problem in industrialized countries.the present study was conducted to investigate the heavy metals concentration in water and sedimentsamples from ship breaking sites of sitakunda to assess the potential ecological risk posed by heavy metalusing different methods. heavy metals concentration was analyzed by atomic absorption spectrosco...
Aims: The general objective of this study was to evaluate heavy metals [Molybdenum (Mo), Cobalt (Co), Cadmium (Cd), Nickel (Ni), Antimony (Sb), Bismuth (Bi)] in the sediments Mfouati River near area impacted by mining operation.
 Study Design: were collected abandoned plant and vicinity. At end sampling, samples analyzed Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES).&#...
