a fast and simple modified quechers extraction method was developed for determination of benzo[a]pyrene (bap) in 137 traditional (sangak), semi-industrial (sangak) and industrial bread samples using spiked calibration curves by gc/ms. sample preparation includes extraction of bap into acetone followed by cleanup with dispersive solid phase extraction. the limit of detection and limit of quantif...
Pollutants are considered the disturbing factors of environment, and among them the heavy metals are more important considering their non-degradability and physiological effects on organisms in low concentrations. The goal of this research was to investigate the effect of industrial landuse on Cd and Pb concentrations in surface soils of the southwest Isfahan. According to satellite images and ...
dehulling is an important step in walnut processing that has considerable effect on the quality, chemical and microbial properties of walnuts. improving dehulling can increase the quality of the final product. this research studied the effect of genotype and hulling method on walnut properties. one experiment was performed as a factorial in a randomized complete block design with three replicat...
Studies have revealed the potential risks to which human health and ecosystems are exposed in the Venice Lagoon, due to the atmospheric deposition of persistent pollutants such as trace metals and organic compounds. A total of seventy-seven atmospheric bulk deposition samples were collected monthly from April 2002 to December 2004, from three sites located in the cities of Mestre and Venice, an...

A range of wastewaters and substrates were examined using mini microbial electrolysis cells (mini MECs) to see if they could be used to predict the performance of larger-scale cube MECs. COD removals and coulombic efficiencies corresponded well between the two reactor designs for individual samples, with 66-92% of COD removed for all samples. Current generation was consistent between the reacto...
This study examined the impact of industrial activities within the LSDPC Industrial estate in Odogunyan, on the quality of the sediments and soils within the area. Twenty samples comprising drainage sediments and soils were obtained from within the drains and surrounding areas of the industrial estate. These samples were dried and disaggregated and sieved to appropriate sizes for geochemical an...
Leptospirosis is a worldwide zoonosis caused by Leptospira interrogans. This study was conducted toevaluate serologic and bacteriologic findings of leptospirosis in clinically-suspected cows. 380 sera and 33urine samples were collected from 6 industrial dairy farms in Tehran suburb, from December 2004 to June2005. The prevalence of disease was determined by microscopic agglutination test (MAT),...
Abstract Background and objectives: Paratuberculosis or John's disease is a chronic infectious disease of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). It results in major economic losses to dairy farm of all over the world and it is the agent causing crohn's disease. The aim of this study was to detect the MAP using PCR in raw-milk samples of cows in shahre-kord. Mater...
