A factorial experiment with the split plot arrangement using the complete randomized block design with three replications was carried out adjacent to the Agriculture School of Shahrood University of Technology in 2010-2011 to study the effects of sulfur and Thiobacillus application and zinc and molybdenum sprays on some traits of green beans. The treatments included three levels of sulfur (zero, 100 kg/ha of sulfur powder, and 100 kg/ha of sulfur powder + Thiobacillus bacteria) as the main factor, and three levels of zinc spray (0, 5, and 10g/l) and two levels of molybdenum spray (0 and 0.5 g/l) as the sub-main factors. The treatments that included sulfur were applied before seeding. Zinc (using zinc sulfate) and molybdenum (using sodium molybdate) were sprayed during the growing season and 5 weeks after planting. Results showed the treatment of applying sulfur at 100 kg/hectare and Thiobacillus bacteria increased leaf fresh and dry weights by 57 and 54%, mean pod length by 14%, and number of lateral branches by 25% compared to the control. Moreover, this treatment increased pod fresh and dry weights by 41.6 and 42.11%, respectively, compared to the treatment of not applying sulfur, and improved yield by 42% compared to the control. Considering the results concerning yield in response to sulfur, zinc, and molybdenum, it can be said that application of sulfur and Thiobacillus together with zinc spray can be very useful in growing green beans.

Continuous surveillance and monitoring of used materials in food processing is a tool for achieving to food safety assurance. Peroxide and Acid values are common indicators to detect fat oxidation, frequent and longtime heating and usage of edible oils in cooking or frying of food. This study aimed to quality assessment of used edible oils in restaurants and fast food centers (Sandwich centers) of Zanjan, Iran by determination peroxide value (PV) and acid value (AV). A total 60 oil samples were collected randomly from restaurants (27 samples) and fast food centers (33 samples) based on cluster sampling plan of the Zanjan city. Titration methods were used to determine Peroxide and Acid values according to Iran national standards protocols No. 4179 and 4178. Peroxide value in 22 (81.48%) and 24 (80%) of oil samples and Acid value in 22 (81.48%) and 30 (90.9%) of samples taken from restaurants and fast food centers were higher than standard limit, respectively. Present investigation has shown that High PV and AV in used edible oils of many restaurants and fast food centers in Zanjan, Iran. High range of Peroxide and Acid values indicate an improper use of oils in food preparing centers and presence toxic compounds in used oils and foodstuffs which threaten food consumers' health. Therefore, continuous surveillance and monitoring of restaurants and food preparing centers and training of chefs, food operators in order to apply proper methods of cooking and frying food is very important and necessary.

Brassica juncea arawali plants were exposed to 0, 100, 200, 400 and 800 mg/l concentrations of Lead (Pb) and Nickel (Ni). Plants were treated with control, ethylene diamine tetraacetic acid (EDTA) and salicylic acid (SA) chelant applications at Micromodel experimental site of Indian Institute of Technology, Delhi in 2009. A high level of combined metal concentrations (1600 mg/l) was taken to assess the feasibility of phytoextraction on a high-level metal contaminated soil. Plants were analyzed for growth parameters, biochemical parameters and metal accumulation. EDTA decreased all morphological parameters whereas SA stimulated them. All biochemical parameters showed declination with increasing Pb and Ni concentrations. A higher accumulation of chlorophyll, soluble sugars, soluble proteins and proline occurred in Indian mustard plants treated with SA. Pb and Ni accumulation in plants increased in a dose-response manner with increasing levels of metal treatments and time. EDTA was found to be more efficient chelant than SA for removal of Pb and Ni from contaminated soil.

In this study, the effect of Mentha piperita essence (MPE) incorporation into cassava films on the hydrophilic and physicochemical properties of the resulting biodegradable films was investigated. The properties included solubility, moisture uptake and contact angle. MPE was added into biodegradable films at different amounts (1, 2 and 3%, w/w total solid). All biofilms were plasticized with 40 % (w/w total solid) combination of glycerol / sorbitol at 1:3 ratio. The incorporation of MPE into cassava films decreased solubility. The moisture uptake of the edible films was found to decrease by MPE reinforcement, and hydrophilic property of biofilms was decreed by increasing MPE.

This study was conducted to determine the residues of mercury (Hg), lead (Pb), copper (Cu) and cadmium (Cd) in the imported tilapia fillets. Thirty random samples from imported tilapia fillets were collected from different markets in Isfahan City, central Iran. They were analyzed using Graphite Furnace Atomic Absorption Spectrometer (Perkin Elmer 800) for Pb, Cu, Cd and flow injection mercury system (Perkin Elmer 400) for Hg. Out of the 30 tested samples, concentration of Hg, Pb, Cu and Cd in the tilapia fillets samples as mean± standard deviation were 0.083±.016, 0.638±0.067, 0.521± 0.081 and 0.136 ± 0.025 mg/kg, respectively. Among these, amounts obtained for all metals except for lead were lower than the permissible level specified by WHO ( P <1%). The Pb concentrations in all examined samples were higher than WHO standards. The continuous consumption of these contaminated fish regularly for long time may lead to health troubles.

In this project decolorization and mineralization of synthetic wastewater containing acid red 33 (AR33) was investigated by Fenton and photo Fenton processes in a batch photo reactor. A comparative assessment using Fenton and photo Fenton processes was performed after initial optimization studies such as varying pH, the concentration of pollutant, peroxide and iron. The color removal and mineralization efficiency of AR33 were calculated by Spectrophotometric and chemical oxygen demand (COD) tests. The degradation efficiency in photo Fenton process (98.5% in 10 min of reaction) was higher than Fenton ones (97.5% in 30 min). After 60 min of reaction, the removal of COD in photo Fenton and Fenton processes was 71% and 37.5%, respectively. Therefore, photo Fenton was the most effective process in partial mineralization of AR33. Kinetic constants were evaluated using pseudo first order equations to obtain the rate constant, K.

Shirin Su Wetland ecosystem, Hamedan Province, western Iran, has a great biodiversity and aesthetic. The distribution and accumulation of heavy metals: Cd, Cr, Cu, Fe, Pb and Zn in sediments were assessed from this wetland in February to May of 2013. The chemical speciation of elements was determined using mixed acid digestion. The results showed that the mean concentrations of metals (microgram per gram dry weight) in sediment samples were: 0.16 for Cd, 23.07 for Cr, 10.62 for Cu, 689.82 for Fe, 27.9 for Pb, 5.01 for Zn. Furthermore the mean concentrations of all metals except Fe in all sediment samples were lower than Threshold Effect Concentration and there are not adverse effects. According to I-geo values, in most stations the sediments quality was classified in unpolluted category. In addition, the sediment samples from station 2 and station 4 accumulated the minimum and maximum mean concentration of metals, respectively. Pearson correlation indicates that the anthropogenic sources of Zn, Fe and Cr are closely related in the sediment from Shirin Su Wetland.

Aluminum toxicity is the most widespread form of metal toxicity to plants in soil acids, initially causing inhibition of root elongation and blocks absorption of water and nutrients. According to this fact that soybean has been widely used in industry, this study investigated the effects of aluminum toxicity on biochemical factors in two varieties of Williams and Katoul of soybean plant. The study was carried out in a randomized design with aluminium (0, 200, 500, 700 µM) treatments and four replications in hydroponic culture. Results of biochemical tests showed that aluminum reduced the content of photosynthetic pigments, flavonoids, phenolic compounds, anthocyanins and reduced sugars in both cultivars of soybean. The proline content decreased with increasing aluminum in var. williams, but at var. katoul increased. It seems that G. max var. katoul suffers less than var. Williams. As regards, proline accumulation under Al stress to be generally higher in G. max var. katoul; hence, these results suggest that var. katoul is more resistant than var. Williams.
铝毒性是植物在土壤酸中最普遍的金属毒性形式，最初引起根系伸长抑制，阻碍水分和养分的吸收。鉴于大豆在工业上的广泛应用，本研究研究了铝毒性对大豆威廉斯和卡托尔两个品种的生化因子的影响。本研究采用随机设计，分别采用铝(0、200、500、700µM)处理，水培培养4个重复。生化试验结果表明，铝降低了两个品种大豆光合色素、黄酮类化合物、酚类化合物、花青素和还原糖的含量。脯氨酸含量随铝的增加而降低，但随铝的增加而增加。看来max var. katoul比var. Williams受的苦要少。Al胁迫下脯氨酸积累量普遍较高;因此，这些结果表明变种卡托尔比变种威廉姆斯更具抗性。

In this research, TiO 2 nanotubes were synthesized by anodized oxidation method and were covered with a hydroxyapatite-silver nanoparticles using photodeposition and dip coating for loading silver nanoparticles and coated hydroxyapatite (HA). The morphological texture of TiO 2 nanotube and Ag-HA nanoparticles on TiO 2 nanotubes surface were studied by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDAX analysis) and X-ray diffraction (XRD). The MCF-7 cell lines were treated with concentrations 1, 10 and 100 µg/ml of TiO 2 nanotubes and HA/Ag/TiO 2 nanotube for 24 and 48h. Finally, the cell viability and IC50% were evaluated using MTT assay. The results show that the HA/Ag/TiO 2 has more positive effect on enhancing the cell death compare to TiO 2 nanotubes and also exerts a time and concentration-dependent inhibition effect on viability of MCF-7 cells.

Heavy metals entrance to fish body tissues and transferring to human body systems after their consuming makes numerous undesirable effects and health problems. The aim of this study was to determine some heavy metals (lead, cadmium and mercury) in fresh fishes marketed in Khorramabad City, west of Iran. In this descriptive study, five samples of 17 fish species with high consumption were purchased randomly in 2014. Measurement of mercury, lead and cadmium was performed using atomic absorption spectrometry. All measurements were performed three times for each sample. Lead mean levels in fish samples was in the range 0.736 -1.005 ppm, cadmium range was from 0.196 to 0.015 ppm and mean content of mercury was 0.431 - 0.107 ppm. At present mean concentration of lead, mercury and cadmium in supplied fishes muscle is lower than maximum recommended levels according to WHO, EC and FDA guidelines. Based on the obtained results of this study and the importance of heavy metals in foods and their impacts on human health, continuous monitoring of heavy metals levels in foods is necessary.
