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.
Evaluation of US/S2O8-2 compilative process performance in the removal of Erythrosine B dye from aqueous solution
Erythrosine B is widely used for dyeing in various applications, especially in the food industry, despite its already proved toxicity and carcinogenicity. Therefore, the purpose of this study is to evaluate the efficiency of the synthesis process of US/S2O8-2 in removing erythrosine B dye from aqueous solution.
Toxicological assessment of inorganic arsenic and zinc content in button mushrooms
Nowadays, discharge of toxic heavy metals into the environment is anincreasing global concern. In light of this and that the per capita consumption of mushrooms has increased in Iran, the current study was carried out to investigate the levels and health-risk assessment of elements arsenic (As) and zinc (Zn) through consumption of button mushrooms marketed in Kermanshah city in 2016.In this descriptive study, a total of 30 samples from 10 brands of edible mushrooms were collected from the market basket of Kermanshah city.
Evaluating the Arsenic, Cadmium, Lead, and Copper levels in certain imported tea samples consumed in iran
Seven majorly consumed brands of several teas (A1, A2, M1, M2, S, D, and C teas) were selected for the present study. In this study, the heavy metal contents including copper (Cu), cadmium (Cd), arsenic (As), and lead (Pb) were assessed in the black tea samples consumed in Iran.
Monitoring the air fungal contamination load in two educational hospitals in Sanandaj, Iran
Opportunistic fungal pathogens are known to increase infection in the health care workers and patients with immune deficiency. This study aimed to investigate the qualitative and quantitative airborne fungal contamination load in two Sanandaj hospitals. In this cross-sectional study, 112 biological samples from 15 different hospital wards were collected for 6 months by using the single-stage Anderson sampler in Sabouraud’s dextrose agar.
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.
