The development of nanotechnology and the possible entry of nanoparticles into aquatic environments have raised environmental concerns. The present study aimed to investigate the effect of iron oxide nanoparticles (Fe3O4) loaded on carbon to remove malathion in order to evaluate the toxicity potential of nanoparticles in aqueous environments. We examined the characteristics of iron oxide […]
Heavy metals contamination is regarded as an environmental pollutant which could be transferred from water sources to soil, plants, animals and human. This study aimed to investigate the removal of lead and nickel from water sources by activated alumina as a low-cost adsorbent. In this regard, a sample of artificial effluent with concentrations of 5 […]
Environmental impact assessment is an integrated, operational and implemental approach for sustainable development. An attitude is considered in which as an integrated system, everything is got into sustainability in the environment and with the environment, as well. Environmental assessment is a tool that has been developed to prevent environmental degradation caused by human activities. Environmental […]
Microbiological and chemical sampling of drinking water wells in Mohammad Shahr, Meshkin Dasht and Mahdasht of Karaj was carried out. Water quality parameters were analyzed using GIS software. The results showed that the reason for the increase of sulfate could be attribution of acidic atmospheric precipitation and sulfate fertilizers. The level of magnesium in groundwater […]
Volatile organic compounds including benzene that are produced in industrial activities, especially those emitted from gas stations, can have undesirable effects on the environment and human health. TANKS 4.09 d software was used to calculate benzene emissions from gasoline storage tanks in gas stations throughout the 22 Districts in Tehran. Benzene emissions 1.5 m above […]
Caustic soda is a substance used for sweetening hydrocarbon products in oil refinery, gas and petrochemical units. The caustic soda-generated salts are increasingly formed during the process of removing impurities like mercaptans, sulfides and nitrates, which finally leave process system through spent caustic discharge. Spent caustic discharge into environment is prohibited due to the presence […]
The developments of industry and technology caused by Industrial Revolution increased the consumption and demand of fossil fuels to sustain economic life. As energy consumption continued to increase in the world, its effects emerged for the first time in the 1970s, necessitating the need for access and planning for the supply of world energy consumption […]
Due to the difficulty of estimating the pollutant gas concentration in power plants, this study aimed to estimate the concentration of the air pollutants in a thermal power plant using the support vector machine model (SVM). The concentration of environmental pollutants in the thermal power plant, Shazand, Iran, at different distances from the chimney was […]
Water is an essential component in the world. The presence of heavy metals in water has dramatic effects on health and ecological process in the environment. Heavy metal pollution in water bodies is an existing and developing problem in the world. There are several methods for removing these pollutions in water. A photocatalytic degradation is […]
The purpose of this study is to measure the sound level in bodybuilding clubs in Mashhad with the approach of maintaining the health of athletes. The metropolis of Mashhad, the capital of Khorasan Razavi province, is located in northeastern Iran. Fifteen bodybuilding clubs were randomly selected by networking method. The sound level in the clubs […]
