2. The dissolved-phase fraction (fdissolved) is a function of the characteristics and level of suspended solids and dissolved organic matter, which may be estimated from the following relationship, where [SS] is suspended solid content, [DOC] is DOC concentration, kd is partition coefficient between the dissolved phase and the suspended solids, and kDOC is the partition coefficient between the ...

OBJECTIVE Diagnose risk environments for schistosomiasis in coastal localities of Pernambuco using geoprocessing techniques. METHODS A coproscopic and malacological survey were carried out in the Forte Orange and Serrambi areas. Environmental variables (temperature, salinity, pH, total dissolved solids and water fecal coliform dosage) were collected from Biomphalaria breeding sites or foci. T...

Shirvan is located in plain in Northern Khorasan province north east of Iran and has semiarid to temperate climate. To investigate the annual changes in some qualitative parameters such as electrical conductivity, total dissolved solids and chloride concentrations which have increased during ten continuous years. Fourteen groundwater sources including deep as well as semi-deep wells were sample...

Water is a unique natural resource among all sources available on earth. It plays an important role in economic development and the general well-being of the country. This study aimed at using the application of water quality index in evaluating the ground water quality innorth-east area of Jaipur in pre and post monsoon for public usage. Total eleven physico–chemical characteristics; total dis...

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...

Refractometric analysis of total solids in serum and urine is simple, accurate, and rapid. Adolph (1) demonstrated the high coefficient of correlation between refractive index and total solids of dog plasma and subsequently employed refractometry as an index of the total solids of human serum (2). Blohm (3), using a dipping refractometer, showed for human urine that the reading given by that fl...
