Effluent quality of ammonia unit in Razi petrochemical complex
Establishment of great industrial centers and ports along the Khur-Musa Estuary in Mahshahr Port (Khuzestan, Iran) have been discharged a high volume of industrial and non-industrial pollutants to this estuary
Assessment of ultrasound irradiation on inactivation of gram negative and positive bacteria isolated from hospital in aqueous solution
Microbial contamination of water poses a major threat to public health. With the emergence of microorganisms resistant to multiple antimicrobial agents, there is increased request for promotion of disinfection methods.
Autohydrogenotrophic denitrification by a bioelectrochemical process: A viability study
In this study, viability of the autotrophic bacteria was investigated in a denitrification process. Bench-scale bioelectrochemical denitrification with separated chambers reactor were applied for nitrate reduction from synthetic wastewater. The influences of current density, retention time, mixing on viability of autotrophic denitrifying bacteria were investigated in the bioelectrochemical reactor (BER).
Effect of solar light on the decrease of microbial contamination in facultative stabilization pond
One of the indexes of stabilization pond is the presence of coliform bacteria in water and wastewater. This study aimed to determine the effect of solar light on coliform variations in stabilization pond. In this experimental study, the effect of light, pH (<7, 7.1–8, 8.1–9), and temperature (10 ºC and 30 ºC) on facultative stabilization pond was studied for six months.
Chromium bioremediation by Alcaligenes sp. strain newly isolated from chromite mine of Sabzevar
In this work, CKCr-6A strain was found to be highly resistant to some toxic heavy metals such asCr+6, Cr+3, Cu+2, Co+2, Cd+2, Pb+2, Hg+2, U+6, tellurium, and selenite.

Coupling adsorption by NiO nanopowder with UV/H2O2 process for Cr(VI) removal
Chromium enters surface and ground waters through the wastewater of electroplating, textile, metallurgical, dye production, and other industries, leading to numerous adverse health effects.
Applicable risk assessment methods in occupational and environmental exposure to nanoparticles – a narrative review
Nanoparticles (NPs) are a heterogeneous group of materials that have various applications, and their risk assessment is an essential condition. This study aimed to review the applicable risk assessment methods in occupational and environmental exposures to NPs.
Determination of arsenic concentration and physiochemical characteristics of water samples from Babagorgor fountain
Since Babagorgorfountain in the Ghorveh city of Kurdistan province is located in the arsenic belt of Iran, to raise awareness about the quality of drinking water from this fountain the concentration of arsenic and other heavy metals as well as other physicochemical parameters were investigated to protect the public health.
The concentration of volatile organic compounds (VOCs) and related factors in the air in barbershops in Sanandaj in 2016
The aim of this study was to determine the density of benzene and toluene in barbershops of Sanandaj and also to determine effective factors for this pollution. A descriptive, analytical study was conducted to measure the volatile organic compound density and determine the effective factors.
