Eutrophication is considered as a serious problem in water reservoirs. Awareness about the eutrophic status of each reservoir could help in providing a better understanding of the problem in a global scale. The present study was conducted to assess temporal and spatial eutrophication index in a water reservoir (Sahand dam) in the northwest of Iran. Physico-chemical parametres that are effective...

heavy metals are considered one of the most important environmental pollution and are dissolved form or adsorbed to the suspended solides in the urban storm runoffs and infiltratire ponds. in this article the heavy metals of urban storm runoff and sediments of infiltration pond in shiraz city have been investigated. the results show different pollutions in the urban storm runoffs such as dissol...

The aim of this study was the increasing of leachate quality using integrated membrane bioreactor (MBR). The reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (COD). The analysis of COD, biochemical oxygen demand (BOD5), total suspended solids (TSS), and total dissolved solids (TDS) were performed in feed and filtrate, whenever the system reached steady stat...

Textile wastewater contains substantial pollution loads in terms of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and heavy metals. Phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (AMATS) is well established environmental protective technique. A lab scale stud...

The Colorado River is a principal source of water for 40 million people and farmlands in seven states the western US Republic Mexico. river has been under intense pressure from effects climate change anthropogenic activities associated with population growth leading to elevated total dissolved solid (TDS) suspended (TSS) concentrations. Elevated TDS- TSS-related issues basin have direct negativ...

Field observations carried out in the Neuse RiverPamlico Sound Estuarine System (NRE-PS), North Carolina, USA were used to develop optical algorithms for assessing inherent optical properties, IOPs (absorption and backscattering) associated with water quality components (WQC). WQCs including chlorophyll a (Chl), volatile (organic) suspended solids (VSS), fixed (inorganic) suspended solids (FSS)...

The liquors were found to be adulterated with impure water from different sources. The measurement of pH, chloride concentration, total dissolved solid, total suspended solid and heavy metals reveals the adulteration in liquors. The duplicate brands contain rectified spirit, caramel, coloring agents, flavoring agents and essential oils which are not according to specifications. The adulterated ...

In the present study the hydrographical parameters like temperature, hydrogen ion concentration (pH), salinity, conductivity, light penetration, turbidity, total suspended solids (mg/l), total dissolved solids, dissolved oxygen (mg/l), biological oxygen demand (mg/l) and nutrients of the surface waters were studied in both stations of Manamelkudi and S.P. Pattinam. All the physico-chemical para...
