Natural and human factors have always threatened the health of Qanats, valuable water sources for arid and semi-arid regions. The present study decided to qualitatively classify eight selected Qanats of East Tehran, Iran, using two multivariate statistical methods, cluster analysis (CA) and principal component analysis (PCA) based on parameters includind pH, TDS, EC, Na2+, Ca2+, […]
In this study systematic random sampling was conducted. To estimate the sample size, 100 households were selected based on the population of the city using Cochran’s formula. Total generated municipal solid waste was consecutively collected, weighed and separated during a week. Then, after providing the required training through face-to-face manner and brochures regarding the economic, […]
Groundwater quality data for Jajarm district was studied by using the Geographic Information System. The interpolation technique were used for the selected factors: Electric conductivity, Total dissolved substance , Total hardness, SAR, and Cl. These parameters of nearly all the wells in Jajarm district were used for the spatial analysis. In addition these parameters were […]
Risk management embarrasses processes aimed at reducing the hazardous effects of an activity through informed actions to predict and prevent unwanted events. Oil sludge disposal is an integral activity in gas refineries, which, if not implemented safely, can impose environmental pollution, health risks and huge cost. The present applied, cross-sectional, analytical survey aimed to identify […]
Today, accidents, explosions, environmental damages and any defects in chemical industry are inevitable events. The ever-increasing of such industries makes effective risk management of these projects necessary to prevent environmental and health pollution and damage. The present study aimed to identify the possible risks caused by chemical industries in the south of Tehran (Iran) by […]
Industrial dust has a significant effect on the environment of mines, which leads to an increase in illness among workers. To decrease the impact of dust on the climate, a wet spraying system is useful for controlling dust in mining companies. In this paper, by using the wet (water) spraying system, dust control in the […]
Sound pollution is known as one of the main disturbances in urban environments. The purpose of this study is to measure the sound level during sports competitions in the vicinity of settlements. For this purpose, Azadi Sports Complex was selected as the largest sports space in the IRAN and the measurements were performed cross-sectional and […]
The statistical attributes of the non-stationary problems such as air quality and other natural phenomena frequently changed. Type-2 fuzzy logic is a robust and capable model to cope with high-order uncertainties associated with non-stationary time-dependent features. This research’s main objective is to present a novel Fuzzy Deep LSTM (IT2FLSTM) model to predict air quality for […]
Fire can destroy forest areas along with air pollution and health hazards. The forest parks of the southern slopes of Alborz, Iran, are amazing tourist destinations for people in surrounding cities. Therefore, we determined the capabilities and limitations and formulated the best strategies to prevent and control fires using SWOT-AHP (A’SWOT) combined method. First, SWOT […]
Acidic mine drainage (AMD) contains large amounts of heavy metal ions and SO42, which can pose serious risks to human and environmental health. Anaerobic bioreactors are considered to be suitable methods for the treatment of acidic effluents due to some advantages such as the need for a small area, easy control, and simultaneous removal of […]
This research is in the applied research group based on its objective, and the data collection method is descriptive-correlational which evaluates the safety culture and the effect of educational intervention using the BASNEF model to promote the employees’ health and safety of Persian Gulf Yadavaran Gas Refinery Co. (PGYGRC). The statistical population of this research […]
