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 […]
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 […]
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 […]
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 […]
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.
