We analyzed water samples from the confluence of three municipal sewage treatment effluent streams, surface water, and whole carp (Cyprinus carpio) for synthetic musks for a period of 7-12 months. The lipid content of each fish was determined and compared with the concentration of musks in the whole fish tissue. Enhanced methods were used for water sampling and musk extraction. The data present...

Sewer systems that convey both sanitary sewage and storm water through a single pipe are referred to as combined sewer systems (CSSs). In dry weather, the CSS is able to convey all flows to the wastewater treatment facility. During periods of heavy rainfall, however, the capacity of the CSS may be exceeded and an untreated combination of sewage and storm water may discharged directly into a nea...

In the present study the effect of sewage water and canal water irrigation were compared by their physicochemical properties and heavy metals concentration in soil. The mean values of different physico-chemical parameters and heavy metals were : Bulk density (gm/cm) 1.26, Water holding capacity(%)-53.60, Temperature(oC)-16.33, Electrical conductivity (dsm-1)0.122, pH-7.5, Organic carbon (%)-1.9...

partial least squares modeling as a powerful multivariate statistical tool was applied tothe simultaneous spectrophotometric determination of silicate and phosphate in aqueoussolutions. the concentration range for silicate and phosphate were 0.02-0.6 and 0.4-3 μg ml-1,respectively. the experimental calibration set was composed with 30 sample solutions using amixture design for two component mix...

Employees at six sewage treatment plants and three drinking water plants were interviewed for the presence of specific medical symptoms. Serum immunoglobulin concentrations, white blood cell counts and fibrinogen degradation product concentrations (FDP) in urine were determined as were the number and species of airborne Gram negative rods in order to characterise exposure to aerosols of sewage ...

Sewage sludge sorption and desorption measurements were conducted for nine diverse contaminants of varying polarity: caffeine, sulfamethoxazole, carbamazepine, atrazine, estradiol, ethinylestradiol, diclofenac, and, for the first time desethylatrazine and norethindrone. Two types of sorption behaviour were observed. Compounds with a log octanol-water partition coefficient, log Kow, below 3 show...

A pot experiment was conducted to study the influence of various irrigation regimes on some metabolic pools of wheat and alfalfa plants. The photosynthetic pigments and soluble proteins of the tested plants significantly increased when irrigated with sewage amended with Scenedesmus quadricauda or Nostoc sp. On the other hand, soluble carbohydrates decreased in wheat shoots at different treatmen...

Microalgal blooms can result from anthropogenic nutrient loadings in coastal ecosystems. However, differentiating sources of nutrients remains a challenge. The response of phytoplankton and benthic microalgae (BMA) to nutrient loads was compared across tropical tidal creeks with and without secondary treated sewage. Primary productivity in the water column was limited by nitrogen availability i...
