Abstract

Agricultural advancement and population growth have prompted increases in food supplies, and higher crop yields have been made possible through the application of fertilizers. Large quantities of livestock and poultry on farms, along with the accumulation of biomass and agricultural residues, can cause contamination of ground water resources and other water sanitation concerns in both developing and developed countries. Nitrate is mainly used as a fertilizer in agriculture, and because of its high solubility in water, it can create biological problems in the environment. High usage of nitrite in the food industry as a preservative, flavor enhancer, antioxidant, and color stabilizing agent can cause human exposure to this toxic compound. Nitrite is 10 times as toxic as nitrate in humans. Nitrate is converted to nitrite and nitrosamine compounds in the human stomach, which can lead to bladder cancer. In this review, sources of nitrate and nitrite exposure were investigated. Furthermore, the review evaluates standard levels of nitrate and nitrite in different foods, and acceptable daily doses of these compounds in various countries. Finally, we discuss valid methods of nitrate and nitrite identification and removal in foods.

Abstract

Meat and meat products are highly prone to microbial deterioration since they are rich in essential nutrients and perishable in nature and if they are not properly preserved, public health problems may occur. Recently, in order to increase the microbial quality of meat and meat products, novel ingredient systems that are associated with natural and organic foods, are applied. Many studies have demonstrated the antimicrobial activity of plant-origin natural antimicrobials in meat and meat products. Nevertheless, advanced technologies can improve the microbial stability and the sensory quality of meat products containing natural extracts and essential oils through different techniques. This paper first reviews the microbial deterioration of meat and meat products and their traditional storage techniques and then discusses the manner and extent of the use of herbal extracts and essential oils in these products.

Abstract

Background: Noise mapping in industry can be useful to assess the risks of harmful noise, or to monitor noise in machine rooms. Using GIS -based software for plot of noise maps in an indoor noisy work environment can be helpful for occupational hygienists to monitor noise pollution.
Methods: This study was carried out in noisy packaging unit of a food industry in Ghazvin industrial zone, to evaluate noise levels by GIS technique. For this reason the floor of packaging unit was divided into squares 2×2 meters and the center of each square was marked as a measurement station based on NIOSH method. The sound pressure level in each station was measured and then the measurement values were imported into Arc GIS software to plot of noise map.

Results: Unlike current method, the noise maps generated by GIS technique are consistent with the nature of sound propagation.
Conclusion: This study showed that for an indoor work environment, the application of GIS technology renders the assessment of noise levels in the form of noise maps, is more real and more accurate than the routine method that is now using by the occupational hygienists.

Abstract

Background;It is important to know media and educational intervention and also produce them according to standards. Thus, media and health educational interventions should evaluate to improve education quality.
Methods;The study sample were whole produced media and interventions in all medical universities, deportments, offices, and centers affiliated to ministry of health in 2008 and in the first half of 2009. Sampling took a census. The evaluating tool was a checklist which made in four domains including pre-media, media and intervention specifications, production, and implementation, evaluation.

Results; 7.1% percent of media and interventions achieved 50 percent score in pre-media. The other results were respectively in media specification 63.7% percent, implementation and production 15.7% percent, and also evaluation 2.9% percent.Intervention just evaluated in pre-media.
Conclusion; The results of the evaluation in health education media indicate that the IEC cycle (Information, Education, Communication) in health care system is an incomplete process. Meanwhile regardless of prerequisite the scoped phase will implicate and lead to educational budget dissipation.

Abstract

Background: Brucellosis (Malta fever) is a major contagious zoonotic disease, with economic and public health importance.
Methods: To assess the effect of meteorological (temperature, rainfall, humidity, and wind) and climate parameters on incidence of brucellosis, brucellosis distribution and meteorological zoning maps of Zanjan Province were prepared using Inverse Distance Weighting (IDW) and Kriging technique in Arc GIS medium. Zoning maps of mean temperature, rainfall, humidity, and wind were compared to brucellosis distribution maps.

Results:Correlation test showed no relationship between the mean number of patients with brucellosis and any of the four meteorological parameters.
Conclusion: It seems that in Zanjan province there is no correlation between brucellosis and meteorological parameters.

Abstract

Background: Environmental gamma ray refers to the gamma radiation from terrestrial sources and building materials. In enclosed spaces radiation can become a health hazard leading to potential increase in the rates of lung cancer. The goal of this study is to assess the exposure to natural gamma radiation of children in the schools of Zanjan province.
Method:The natural gamma radiation was assessed in 46 primary schools of Zanjan province. A total number of 75 classrooms were studied. The measurements were performed in classrooms and schoolyards using a Geiger–Muller detector (RDS-110). Alongside radiation measurements, all the data corresponding to the characteristics of each school building were collected.

Results: The results showed that the outdoor dose rate ranged from 82 to 106nSv h-1 while gamma dose rate due to inside classrooms ranged from 106 to 137nSvh-1. The findings represented that the highest indoor gamma dose rate belonged to the buildings of more than 30 years and metal frame and brick (P<0.05).

Conclusion: We concluded that the effective dose due to gamma radiation from terrestrial sources and building materials for students of primary schools in Zanjan province (0.83 mSv) was higher than worldwide average of the annual effective dose (0.48 mSv).

Abstract

 Nowadays, underground water is the main source of drinking water that contamination to organic pollutants such as MTBE is an important issue. One of the suitable methods for these types of pollutants is the advanced oxidation methods. Advanced oxidation processes (AOPs) are involved in the production of highly reactive hydroxyl radicals that oxidize organic matter such as MTBE and even lead to its full mineralization. The use of light in the presence of catalysts is one of the methods of advanced oxidation processes. Photocatalytic methods widely used for a wide range of toxic and none degradable pollutants. Recent advances in the fabrication and characterization of Nano scale materials have extensively developed research into methods for the preparation of highly effective Nano-sized catalysts for the removal of chemical contaminants. This review article discusses the work on the photo catalysis of MTBE in water using different types of photo catalysts.
