1 - Removal of Zn2+ and Cr6+from waste water Samples, using natural Iranian (Aftar) Zeolites
S. Peyravi,, R. Zahiri K. Moradi HersiniThis paper concerns the removal of Zn2+ and Cr6+ ions from waste water using a naturally occurring zeolite from semnan region in Iran.

A continuous fixed-column study was carried out by using zeolite as a low-cost adsorbent for the removal of Zn2+ and Cr6+ ions from aqueous solution under the effect of various process parameters such as, grain size and time. The efficiency of removal is higher for Zn than Cr ions. The Zn2+ and Cr6+ ions uptake by zeolite increased with initial ions concentration and column height, but decreased as the flow rate increased. The adsorption capacity reached a maximum at grain size of 0.71mm. Manuscript profile -

2 - Metal bioaccumulation, enzymatic activity, total protein and hematology of feral pigeon (Columba livia), living in the courtyard of Ferronickel smelter in Drenas
I. Elezaj, , , Q. Selimi K. Letaj A. PlakiqThis study was undertaken to evaluate the effects of Ferronickel smelter in concentration  of lead, cadmium, zinc, copper and nickel in tissue of femur, tibia, liver kidney and testes, levels of plasma alanin aminotransferase (ALT), aspartat aminotransferase (AST), a MoreThis study was undertaken to evaluate the effects of Ferronickel smelter in concentration  of lead, cadmium, zinc, copper and nickel in tissue of femur, tibia, liver kidney and testes, levels of plasma alanin aminotransferase (ALT), aspartat aminotransferase (AST), alkaline phosphatase (AP) blood δ-aminolevulinic acid dehydratase (ALA-D), serum total proteins, hematocrit and hemoglobin in Feral pigeons. Pb was detectable only in tissues of femur and tibia; Cd and Cu in liver and kidney, Zn in all tissues while Ni only in tissues of pigeons of courtyard smelter. Zn concentration was significantly higher (P<0.05) in kidney of courtyard smelter in comparison with reference. Plasma AP was significantly higher (P<0.001) in pigeons of reference in comparison with pigeons of courtyard smelter, while ALT and AST were relatively unchanged. The ALA-D activity of pigeons from courtyard of smelter was significantly inhibited (P<0.001) and an inverse correlation between Pb concentration in femur and tibia and ALA-D activity (r = -877; P<0.001; r = -0.787; P<0.01) was established. The total serum proteins of pigeons of courtyard of smelter was significantly lower (P<0.001). Hematocrit and haemoglobin were unchanged. Suggestion: Feral pigeons as worth biomonitoring organisms for evaluation of environmental pollution based on Ferronickel industry. Manuscript profile -

Number of aberrant cells, and frequency of micronuclei (MN), in meristematic root tip cells of treated plants (Tradescantia), were significantly increased (P<0.001; P<0.001 respectively), while the mitotic index in all treated plants was progressively decreased in comparison to the negative control. The results of present study indicate that Tradescantia root-tip micronucleus assay with direct exposure of intact plants is an appropriate method which enables to detect genotoxic effects of effluent waters.

4 - The Effects of IBA and H2O2 on Rooting of 2 Olive Cultivars
E. Asl moshtaghi A.R. ShahsavarTwo groups of olive cultivars were characterized as showing low (Tokhmkabki) and high(Roghani) rooting percentage after application of IBA treatment. Semi-hard wood cuttings were dipped in H2 2O2 (0-3.5% w/v) and IBA (4000 mg.l-1) and also they were investigated in comb MoreTwo groups of olive cultivars were characterized as showing low (Tokhmkabki) and high(Roghani) rooting percentage after application of IBA treatment. Semi-hard wood cuttings were dipped in H2 2O2 (0-3.5% w/v) and IBA (4000 mg.l-1) and also they were investigated in combination. H2O2 alone did not stimulate rooting of olive cuttings and there were no significant differences between this treatment and control in both cultivars. It was obvious that IBA treatments increased the rooting percentage, number of root cuttings, root length and root fresh\dry weight in 2 olive cultivars but the combination of IBA and H 2Oin some factors was more effective but there were no significant differences when IBA was used instead of in both cultivars.

In this study, seven types of mercury resistant bacteria were separated from industrial waste and minimum inhibitory concentration (MIC), were determined for these bacteria. Results showed that two strains of bacteria, which isolated from waste water detergent plants, are more resistant to mercury and able to grow at the presence of 52 ppm of mercuric chloride. These bacteria could be used for biological treatment of mercury in contaminated wastewater. Manuscript profile -

6 - Presence of Aflatoxin M1 in Pasteurized and UHT Milk Commercialized in Shiraz, Khuzestan and Yazd, Iran
E. Rahimi Z. Nilchian A. BehzadniaAflatoxin M1 (AFM1) is a hydroxylated metabolite of the carcinogen aflatoxin B1 (AFB1), and may be found in the milk of lactating animals that have ingested feedstuffs contaminated with AFB1 Between Jun 2010 and March 2011, 149 samples of pasteurized (n=90) and UHT (n=5 MoreAflatoxin M1 (AFM1) is a hydroxylated metabolite of the carcinogen aflatoxin B1 (AFB1), and may be found in the milk of lactating animals that have ingested feedstuffs contaminated with AFB1 Between Jun 2010 and March 2011, 149 samples of pasteurized (n=90) and UHT (n=59) milk were collected from supermarkets in the cities of Shiraz, Khuzestan and Yazed, Iran. All samples were analyzed for AFM1 contamination by ELISA and 142 (95.3%) were positive with mean concentrations 41 ng.l-1. These concentrations are lower than the standads of Codex Alimentarius and FDA (500 ng.l-1), but 33 samples (22.1%) had higher concentrations than the maximum tolerance accepted by some European countries (50 ng.l-1). Mean concentrations of AFM1 in pasteurized and UHT milk were 39 and 46 ng.l-1, respectively. Mean concentrations of AFM1 in fall and winter samples were significantly higher (P<0.05) than those of summer but differences between AFM1 concentrations of fall and winter samples were not significantly different. No significant differences in Concentrations of AFM1 in milk samples between Shiraz, Khuzestan and Yazd. Considering the results, this survey revealed a high frequency of AFM1 contamination in milk samples from central part of Iran. Manuscript profile -

In this study, 42 adult male mice NMRI race weighing 35-40 gr and from age 8 to 10 weeks were divided into 6 experimental groups and one control group. Experimental groups 1-2-3 with the using of chamber, as inhalation 20 minutes were exposure to spray the amount 1 cc of mixture of bleach and detergent by nebulizer. Experimental groups 4-5-6 were for 35 minutes to inhale the same amount of material. Mice killed at 24-48-72 hours after inhalation and the trachea was studied pathology. In microscopic sections of tissue taken from the trachea the experimental group compared with the control group was changed to include: stimulation and activation of the respiratory epithelium hungarian (Mocusa layer), reducing the length of ciliated columnar cells, reducing the number of goblet cells ,loss of cilia, chaos and clutter on the order of tissue. In addition, statistically, the changes in length of ciliated columnar epithelium cells in experimental groups 3 and 6 seen significantly decreased than control group and the number of experimental groups 2 and 4 goblet cells significantly increased compared to control group, experimental group 6 was significantly decreased than the control group. As a result discussion, increasing the inhalation time of mixing bleach and detergent, also as time passed, cause to increase the tissue damage and changes. Manuscript profile
