This experiment was conducted in the laboratory of Gorgan University of Agricultural Sciences and Natural Resources, in 2014. Results showed that the interaction of cola with peppermint essence and apple extract with rosemary essence at above concentrations increase the vase life of flower, flower diameter and anthocyanin at significantly level of %1. The highest amount of vase life was related to concentration of 500 ml L -1 of cola (15 days), while vase life in control treatment (distilled water) was 9 days. The highest flower diameter was recorded in apple extract (45 ml L -1 ) + Rosemary essence (2000 mg L -1 ). The highest amount of anthocyanin was obtained in cola treatments of 500 ml L -1 + essence of peppermint, 30 and 45 ml L -1 of apple extract+ rosemary essence. Besides, flowers treated by 375 ml L -1 of cola + peppermint essence had the highest chlorophyll content.

A laboratory study was conducted to investigate the influence of different kinds of amendments on cadmium (Cd) stabilization in a Cd-spiked soil. The amendments were municipal solid waste compost (MSWC), Coal fly ash (CFA), rice husk biochars prepared at 300°C (B300) and 600°C (B600), zero valent iron (Fe 0 ) and zero valent manganese (Mn0). The Cd-spiked soils were separately incubated with selected amendments at the rates of 2 and 5% (W/W) for 90 days at 25 °C. Soil samples were extracted by EDTA for periods of 5 to 975min. In addition, sequential extraction was used as a suitable method for identification of chemical forms of Cd and their plant availability. The addition of amendments to soil had significant effects on desorption and chemical forms of Cd. Changes in Cd fractions and their conversion into less soluble forms were clear in all treated soils. The addition of amendments resulted in a significant reduction in mobility factor of Cd compared to the control treatment. Among all amendments tested, Fe 0 was the most effective treatment in decreasing dynamic of Cd. Biphasic pattern of Cd desorption kinetic was fitted well by the model of two first-order reactions.

Behavioral abnormalities were observed in fishes exposed to high levels of malathion. The specimens exposed to malathion had significantly lower RBC, WBC, Hb, PVC but higher MCV and MCH than those of the control group. No significant difference was detected in MCHC the exposed and control specimens. Hematological parameters (except MCHC) were significantly correlated with exposure time. In conclusion, malathion showed extensive haematological effects on C. damascina that might be used as bioindicator of this pesticide in flowing waters.","PeriodicalId":15347,"journal":{"name":"Journal of Chemical Health Risks","volume":"5 1","pages":"209-220"},"PeriodicalIF":0.0,"publicationDate":"2015-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68029158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Processing of foods at high temperatures used to cook them can cause the formation of carcinogenic substances like acrylamide, and this risk remains even if the trans-fat is removed. The low temperatures employed in this method resulted in the products with the desired texture, nutritional, and colour. The purpose of this research was evaluation of the variable effects of osmotic dehydration process (ambient pressure, contact time of product and solution, concentration and temperature of osmotic solution) on the quality factors of product (colour changes, texture, moisture, oil uptake, and water loss to solid gain ratio) and achieving the optimum process conditions. Studying the quality parameters of the product, the temperature range of osmotic solution, pressure, concentration of the osmotic solution and contact time of product and solution were assumed as 30 to 50°C, 500 to 700 mbar, 30 to 50% and 60 to 180 min, respectively. The test plans involving 31 tests were obtained by using response surface statistical models and central composite design. They were fried at the condition of 108oC, 8 min and 320 mbar by using statistical correlations, 48.71oC for the osmotic solution temperature, 592.07 mbar for the pressure, 62.92 min for the time and 34.87% for the osmotic solution. Concentrations were obtained as optimum conditions of osmotic dehydration of kiwi slices under reduced pressure. In summary combination of osmotic dehydration and vacuum frying improved the quality of the final fried kiwi, so this method is recommended for production of healthy products.","PeriodicalId":15347,"journal":{"name":"Journal of Chemical Health Risks","volume":"4 1","pages":"13-22"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68031916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
