Introduction and The nature and type of chemicals used in industrial processes, treatment and management of wastes resulting from them complicated. This study aimed to investigate wastewater management, manufacturing industries Savojbolagh city Alborz Province was from an environmental standpoint in 2013-2014
This study is type of cross-sectional. The three field visit, a questionnaire survey data and control / monitoring in industrial plants with more than 50 workers (totaling 108 units) were used. To do this research from the Environmental Protection Agency's questionnaire was used. The questionnaire included questions about the quantity, quality and wastewater management, industrial manufacturing setting. How to manage of industries Wastewater treatment plants, based on four indicators of wastewater production, production per capita, per capita of BOD, per capita of COD, from 1 to 6 are ranked. Rated for better environmental management in each index is defined.
The produced wastewater industries studied, 1942 cubic meters per day respectively. Food industry alone produces 59 percent of total industrial wastewater. The highest per capita BOD related to the industry (slaughterhouse) by g / d 320 per worker and the cellulose industry with the highest per capita COD g / d561 per person. 76% of Studied industries do not have any strategy to reduce the production of waste. 34% of industries have treatment plants that only 17% of the industry to comply with effluent discharge standards. The most common method of disposal of Treated wastewater and untreated are well absorbed.
Based on this assessment, management of industrial wastewater for agriculture (slaughterhouse) unfavorable and non-metallic mineral industries were favorable.

Mashhad is one of the largest city in Iran which heavy transport vehicles and industries is threaten air quality. The aim of this study was to evaluate the changes in air quality index (AQI) from 1391 to 1393 spring seasons and zoning with ArcGIS.
this study is descriptive, the spring of 1391 to 1393 PM10, PM2.5, NO2, SO2, CO and O3 were evaluated for AQI index at four online stations in the city and then classified air quality into six group’s daily include good, moderate, unhealthy for sensitive people, unhealthy, very unhealthy. Zoning was done with ArcGIS.
The most average on days of air quality obtained in good condition and has been responsible for PM2.5 and NO2 emissions is these days. According to the zoning maps AQI values in 1391 to 1393 years gained in Sadaf station the northwest of Mashhad in good condition but center and south of Mashhad was more polluted. AQI index values between 1391 and 1392 from April to June, have improved but the air quality has dropped in 1393.
The air quality in Mashhad city in the crowded southern and center city is unhealthy in some spring days, so in next years for pollution control, traffic management, changes in fuel quality, management of home heating systems, use of electric transportation will be needed.

Introduction and AIDS (Acquired Immune Deficiency Syndrome) is as one of the greatest social - health problems in many communities in the Twenty-first century. This disease is spreading rapidly due to low awareness and failure to deal properly with it. The aim of this study was to determination of knowledge and attitude about HIV/ AIDS in health volunteers of Eghlid health centers in 2015.
This was cross - sectional study in which from health volunteers of Eghlid health centers 240 persons through census were selected. The data was collected by questionnaire and were analyzed by Independent t-test and one-way ANOVA.
The results showed that health volunteers have acquired 74.4% from the knowledge and 66.9% from the attitude scores. Also 19.1%, 18.3% and 30.6% of health volunteers respectively do not know sexual contact, blood transfusions and blood products and Occupational Contact such injuries with contaminated needles as a way of transmitting the HIV virus. Between score of knowledge and age (P=0.006) and Degree (P≤0.001) there was a significant relationship.
Considering the relatively low level of knowledge about transmission of HIV/ AIDS in health volunteers and the increasing level of knowledge with the increasing level of literacy, it was suggested that firstly health volunteers with higher literacy levels are selected for teaching and secondly, in the case of HIV virus transmission, training packages and teaching practices that are given to Volunteers will be reviewed.

Introduction & Air pollution is one of the main problems of megacities and threatens the health of residents seriously. Pollutant changes surveys, comparison with standards, and informing the health authorities and public, therefore, is essential to develop preventive schemes. Isfahan and Shiraz are the major cities of Iran and air quality of them is very important. This study was conducted to determine the Comparative Investigation of air quality Health in Tehran metropolis based on air quality index over a period of five years (2011-2015).
This Study was a descriptive–analytic study. In order to AQI determination, At first , hourly data of four criteria pollutants were taken from the environmental protection agency tehran and Air Quality Control Company and validated according to the WHO guidelines and based on standard table and equation, daily AQI was determined for each pollutant. The highest value between the calculated indexes for all of the stations and the pollutant that was responsible for this index, introduced as a final index and responsible pollutant of day, respectively.
Results showed that, Air quality in Tehran in years 93-89 respectively.327, 330, 343, 350, and 352 days of year, the AQI was over the Environment Protection agency of Iran's standard, respectively. Also in all of the cities the PM2/5 was the main responsible pollutant.
By comparing air quality in Tehran in five years showed that the air quality is not proper in terms of health status and level of air pollution in Tehran is increasing.
