Background and purpose: Karaj River is the biggest aquatic ecosystem in Alborz province which is exposed to a variety of pharmaceutical pollutants. These pollutants have adverse effects of on surface water, biota and even humans. This research aimed to evaluate the level of contamination caused by widely used antibiotics in Karaj River, effluent, and wastewater treatment plants in 20 stations. ...

Pharmaceuticals are being used at an increasing rate, and end up in wastewater through excretion and disposal. They also end up in the effluent water of wastewater treatment plants because they are not specifically designed for pharmaceutical removal. Several studies suggest diverse negative effects on aquatic life that are exposed to these trace amounts of pharmaceuticals in their habitats. Th...

Due to vast probable contaminations from pharmaceutical effluent, the main purposes of this study were to decrease the heavy metal toxic levels from waste water of pharmaceutical research and educational laboratories. The potential ability of A. Vera for cleaning up contaminated educational sites soil and the probable capability of this plant to phytoextract different metals (Chrome (III) and (...

Widespread use of pharmaceuticals has resulted in mixture concentrations ranging from mg/L in effluent to µg/L concentrations in surface water. In a 2008 study, 13 pharmaceuticals, ranging in amounts from 0.0028 to 0.1757 µg/l, were identified in the Tennessee River, USA and its tributaries. In order to address the need for risk assessment of environmentally relevant pharmaceutical mixtures, <e...

The presence of human pharmaceutical compounds in surface waters is an emerging issue in environmental science. Low levels of many active pharmaceutical ingredients are detected in the aquatic environment as a result of pharmaco-chemical industrial waste spill-offs in draining water. In the manufacturing of pharmaceutical drug substances azides are used as reagents or when they are generated so...

Microbial community structure of two distinct effluent treatment plants (ETPs) of pesticide and pharmaceutical industries was assessed and defined by (i) culture dependent and culture independent approaches on the basis of 16S rRNA gene sequencing, (ii) diversity index analysis - operational taxonomic units (OTUs). A total of 38 and 44 bacterial OTUs having 85-99% similarity with the closest ma...

Aquatic macrophytes have been widely studied because of their capability of absorbing contaminants from water and their subsequent use in biomonitoring. This study presents a comparison of Cr accumulating potential of submerged aquatic plants viz Vallisneria spiralis and Hydrilla verticillata. These plants were treated with various concentrations of treated tannery effluent collected from UASB,...

The activated sludge process is the most widespread sewage treatment method. It typically consists of a pretreatment step, followed by primary settling tank, an aerobic degradation process, and, finally, secondary tank. effluent then usually chlorinated and discharged to water body. Tertiary aims at improving characteristics facilitate its reuse. In this work, through literature review prominen...
