1, 3-Butadiene (BD) is primarily used for the production of synthetic rubbers and polymers, which are found in many industrial and consumer products. BD is suspected to be both carcinogenic and genotoxic to humans. This study aims to compare occupational exposure limits (OELs) based on BD’s carcinogenic effects using threshold and non-threshold methods in industrial […]
Environmental Management Plan (EMP) is regarded as a guidance document to attain and measure compliance with the mitigation requirements and environmental protection of projects, which are normally requirements for project approvals. The study mainly aims to present an Environmental Management Plan for dams whose construction was suspended by opposing stakeholders for the harmful impacts on […]
A nanoparticle is a small particle that ranges between 1 to 100 nanometers in size. Undetectable by the human eye, nanoparticles can exhibit significantly different physical and chemical properties to their larger material counterparts. Metal oxide nanoparticles pollution has become a major environmental concern due to its widespread production and usage. The potential toxic effects […]
Preserving the health of food resources, including drinking water, is considered one of the most important issues in human usability. Therefore, all efforts and research are based on finding and utilizing the best methods to safeguard the hygiene of water and municipal wastewater, aiming to protect human health and improve the quality of treated sanitary […]
The present applied research aimed to model energy management in office buildings of District 5 Municipality of Tehran, Iran. The components affecting energy consumption were extracted via an integrated approach (including in-depth survey and semi-structured interviews with experts) using coding method and prioritized by Analytic hierarchy process and Expert Choice. The proposed model was fitted […]
This research aims to assess the concentrations of benzene, toluene, and ethylbenzene along the Hakim Expressway, from Milad Tower to Resalat Tunnel, in order to investigate the impact of traffic, a major contributor to air pollution in Tehran, and the release of volatile organic compounds (VOCs) resulting from fossil fuel burning. Conducted in the fall […]
As the world entered the industrial era, the nature of environmental threats and dangers posed by technology also have gone through fundamental changes. One of these environmental pollutants is the propagation of waves with different wavelengths in the environment. In this study, we aimed to investigate the effect of 2.45 GHz microwaves on blood […]
Dez River is considered as one of the highest water rivers after Karoon River, supplying water for tens of towns and villages as well as thousands of acres of agricultural lands, several fish farming plans and industrial factories. Hence, the water quality of Dez River is one of the major concerns of the area. This […]
ABSTRACT: The preset study investigated heavy metals located on the leaves of street side trees in crowded areas of Tehran in order to evaluate the metal pollution caused by cars. Contamination factor, Index of geo-accumulation, enrichment factor, modified degree of contamination, and Pollution load index were used to describe the pollution of the environment and […]
Tehran is the most affected town by light pollution in Iran. In this study, the role of the regional topography in the distribution of light pollution in Tehran was evaluated using digital images recording and analyzing the obtained images from Tehran sky-glow by East and South in standard image-processing Software. The scale of Tehran’s glowing […]
