Impact of leachate on groundwater pollution due to non-engineered municipal solid waste landfill sites of erode city, Tamil Nadu, India
Iranian Journal of Environmental Health Science & Engineering - Tập 9 - Trang 1-12 - 2012
Rajkumar Nagarajan, Subramani Thirumalaisamy, Elango Lakshumanan
Leachate and groundwater samples were collected from Vendipalayam, Semur and Vairapalayam landfill sites in Erode city, Tamil Nadu, India, to study the possible impact of leachate percolation on groundwater quality. Concentrations of various physicochemical parameters including heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn) were determined in leachate samples and are reported. The concentrations...... hiện toàn bộ
Monitoring of some pesticides residue in consumed tea in Tehran market
Iranian Journal of Environmental Health Science & Engineering - Tập 10 - Trang 1-6 - 2013

Effect of extremely low frequency electromagnetic field exposure on sleep quality in high voltage substations
Iranian Journal of Environmental Health Science & Engineering - Tập 9 - Trang 1-7 - 2012
Tayebeh Barsam, Mohammad Reza Monazzam, Ali Akbar Haghdoost, Mohammad Reza Ghotbi, Somayeh Farhang Dehghan
This study aims to investigate the effect of extremely low frequency electromagnetic fields exposure on sleep quality in high voltage substations (132, 230 and 400 KV) in Kerman city and the suburbs. For this purpose, the electric field intensity and magnetic flux density were measured in different parts of substations, and then the occupational exposure was estimated by averaging electric field i...... hiện toàn bộ
Environmental impacts of forest road construction on mountainous terrain
Iranian Journal of Environmental Health Science & Engineering - Tập 10 - Trang 1-8 - 2013
Erhan Caliskan
Forest roads are the base infrastructure foundation of forestry operations. These roads entail a complex engineering effort because they can cause substantial environmental damage to forests and include a high-cost construction. This study was carried out in four sample sites of Giresun, Trabzon(2) and Artvin Forest Directorate, which is in the Black Sea region of Turkey. The areas have both steep...... hiện toàn bộ
Removal of Co(II), Cu(II) and Pb(II) ions by polymer based 2-hydroxyethyl methacrylate: thermodynamics and desorption studies
Iranian Journal of Environmental Health Science & Engineering - Tập 9 Số 1 - 2012

Magntic susceptibility as a proxy to heavy metal content in the sediments of Anzali wetland, Iran
Iranian Journal of Environmental Health Science & Engineering - Tập 9 - Trang 1-12 - 2012
Mohammad Reza Vesali Naseh, Abdolreza Karbassi, Fereydoon Ghazaban, Akbar Baghvand, Mohammad Javad Mohammadizadeh
Heavy metal concentrations and magnetic susceptibility of sediment samples were analyzed as indicators of urban and industrial contamination in Anzali wetland in Gilan, Iran. The aim was to investigate the suitability of magnetic properties measurements for indicating heavy metal pollution. The concentration of six heavy metals (Ni, Cr, Cd, Zn, Fe, and Pb) was determined in different depths of fou...... hiện toàn bộ
Biodegradation of high concentrations of benzene vapors in a two phase partition stirred tank bioreactor
Iranian Journal of Environmental Health Science & Engineering - - 2013
Ali Karimi, Farideh Golbabaei, Masoud Neghab, Mohammad Reza Pourmand, Ahmad Nikpey, Kazem Mohammad, Mohammad Reza Mehrnia
Abstract The present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and o...... hiện toàn bộ
Degradation of a textile reactive azo dye by a combined biological-photocatalytic process: Candida tropicalis Jks2 -Tio2/Uv
Iranian Journal of Environmental Health Science & Engineering - Tập 9 - Trang 1-7 - 2012
Narjes Jafari, Rouha Kasra-Kermanshahi, Mohammad Reza Soudi, Amir Hossein Mahvi, Sara Gharavi
In the present study, the decolorization and degradation of Reactive Black 5 (RB5) azo dye was investigated by biological, photocatalytic (UV/TiO2) and combined processes. Application of Candida tropicalis JKS2 in treatment of the synthetic medium containing RB5 indicated complete decolorization of the dye with 200 mg/L in less than 24 h. Degradation of the aromatic rings, resulting from the destr...... hiện toàn bộ
Algal production of extra and intra-cellular polysaccharides as an adaptive response to the toxin crude extract of Microcystis aeruginosa
Iranian Journal of Environmental Health Science & Engineering - Tập 9 - Trang 1-7 - 2012
Mostafa Mohamed El-Sheekh, Hanan Mohamed Khairy, Rania El-Shenody
This is an investigation concerned with studying the possible adaptive response of four different unicellular algae, Anabaena PCC 7120, Oscillatoria angustissima, Scendesmus obliquus and Chlorella vulgaris, to the toxin of Microcystis aeruginosa (Kützing). The effects of four different concentrations, 25, 50, 100 and 200 μg mL-1 of microcystins crude extract of M. aeruginosa, on both intra and ext...... hiện toàn bộ
Investigation of natural effective gamma dose rates case study: Ardebil Province in Iran
Iranian Journal of Environmental Health Science & Engineering - Tập 9 - Trang 1-6 - 2012
Sadegh Hazrati, Abbas Naghizadeh Baghi, Hadi Sadeghi, Manouchehr Barak, Sahar Zivari, Soheila Rahimzadeh
Gamma rays pose enough energy to induce chemical changes that may be biologically important for the normal functioning of body cells. The external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined. In this research natural background gamma dose rates and corresponding annual effective doses were determined for selected cities...... hiện toàn bộ
