Hazard assessment for a pharmaceutical mixture detected in the upper Tennessee River using Daphnia magna
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...
متن کاملGeochemical assessment and pollution of heavy elements in the Revenj River sediments in the northwest of Torbat-e-Jam
In this study, the pollution of the Revenj River sediments with heavy elements has been studied. Revenj River catchment with an area of 131 Km2 is located 20 kilometers from the city of Torbat-e-Jam (northeast of Iran). To investigate the contamination of sediments with heavy elements, 15 samples of sediments were taken from the area and analyzed by ICP-MS. In order to monitor the contamina...

Background; Contamination of water and soil through non-point sources such as road runoff causes environmental concern. The aim of this study is to determine the effect of Zanjan – Chavarzagh road on the total organic carbon (TOC) content of sediments in tributaries and the river that lead to Taham Lake. Methods; In tributaries and the river 69 soil and sediment samples were taken and the Tota...
متن کاملPyrethroid insecticide concentrations and toxicity in streambed sediments and loads in surface waters of the San Joaquin Valley, California, USA.
Pyrethroid insecticide use in California, USA, is growing, and there is a need to understand the fate of these compounds in the environment. Concentrations and toxicity were assessed in streambed sediment of the San Joaquin Valley of California, one of the most productive agricultural regions of the United States. Concentrations were also measured in the suspended sediment associated with irrig...
متن کاملDetermination of Selected Pesticide Residues from Gilgel Gibe (I) Hydroelectric Dam Reservoir and Its Tributaries, Jimma Zone, Ethiopia
In this study, the level of selected organophosphorus and organochlorine pesticide residues from water samples of Gilgle Gibe (I) hydroelectric dam reservoir and its potential tributaries, Jimma zone, Ethiopia, was determined by gas chromatography-electron capture detector (GC-ECD). Low density based dispersive liquid-liquid microextraction (LD-DLLME) using toluene (as extractant) and acetonitr...
