Present study was carried out to determine the important physico chemical parameters of water of Tapi estuary in Hazira industrial area. Tapi estuary receives the inputs of organic matter and nutrients coming from the domestic wastewater discharges from Surat City, a textile hub as well as industrial effluents from Hazira, a major industrial Complex of Gujarat, India. Uncontrolled discharges of domestic wastes and industrial effluents have affected the estuary. Present study was carried out from June - 2011 to May 2012 to study the impacts of uncontrolled discharges on physicochemical characteristics of water. Samples were collected monthly in the morning during low tide to determine the important physico chemical parameters Viz. Turbidity, conductivity, total solid, total dissolved solid, salinity, pH, dissolved oxygen, BOD, COD, Calcium, chloride, sodium , potassium and nutrients like nitrate, nitrite and phosphate. Dissolved oxygen was found extremely low during the study period. High biochemical oxygen demand (BOD) and Chemical Oxygen demand (COD) showed that the water quality of estuary has been affected by industrial and domestic effluents.

The physico-chemical properties of honey produced by the stingless bee Melipona mondury from Atlantic Forest in the state of Bahia, northeastern Brazil were evaluated. The evaluated characteristics included: water content, electrical conductivity, pH, acidity, water activity, ashes, diastase, hydroxymethylfurfural (HMF), reducing sugars and saccharose values. The honey samples showed mean values of 29.18% for moisture; 391.5 μS for electrical conductivity; pH of 4.06; 34.3 meq kg-1 for acidity; 0.73 for water activity; 0.18% for ashes; 4.05 (Goethe unit) for diastase; 1.60% for HMF; 65.42% for reducing sugars; and 2.14% of saccharose. Only the diastase activity was above the limits accepted by the Technical Regulation for Identity and Quality of Honey (Brazilian Ministry of Agriculture and Supplies). Most parameters are according to those reported in honeys from other species of stingless bees in Brazil.

The present experiment was conducted to detect quality and level of the adulteration in milk collected from Dharchuni, Atani and Khamar bazar of Muktagacha Upazilla. Organoleptic parameters used to monitor the status of milk samples were color, flavor, taste, texture; physical parameter used was specific gravity; chemical parameters used were acidity, fat content, protein content, lactose content, ash, total solids, solids-not-fat; and the adulteration test used were starch test and formalin test. The tested milk samples showed significantly differences (p<0.05) for specific gravity, protein, fat, lactose and TS contents. No significant difference (p>0.05) were found for %acidity, ash content, and SNF content of milk samples. Milk collected from Khamar Bazar was higher for protein and fat contents than other markets. Adulteration tests, for all the samples were found negative. Although, there were some fluctuations among the parameters of milk samples regarding standard values; all of the milk samples were found to be acceptable.

The main objective of this study is to assess nutritional and hygienic qualities of raw milk collected in situ in dairy cattle farms in the region of Guelma, Algeria. For this purpose, a total of 144 milk samples were collected and analyzed to determine their physicochemical characteristics and bacteriological quality. Results showed an acceptable nutritional quality, with a poor bacteriological quality. The average contamination was 11.69 x 105 CFU ml-1 for total flora, against 23.44 x 105 CFU ml-1 for total Coliforms and 7.34 x 104 CFU ml-1 for fecal Coliforms. In addition, 6% of total samples were positive for Clostridium. For the suspected pathogenic flora, Staphylococcus aureus has been detected in 9 samples; however, all milk samples were devoid of Salmonella. The poor quality of milk reflects the dismal conditions of production and the no-control of hygienic practices.

Biodiesel is becoming prominent among the alternatives to conventional petro-diesel due to economic, environmental and social factors. The quality of biodiesel is influenced by the nature of feedstock and the production processes employed. High amounts of free fatty acids (FFA) in the feedstock are known to be detrimental to the quality of biodiesel. In addition, oils with compounds containing hydroxyl groups possess high viscosity due to hydrogen bonding. American Standards and Testing Materials, (ASTM D 6751) recommends FFA content of not more than 0.5% in biodiesel and a viscosity of less than 6 mm2/s. In this experiment the seed oils of 30 Neem (Azadirachta indica. A. juss) biotypes were screened and evaluated for their physico-chemical parameters for their potential in biodiesel. The properties of Neem biodiesel were compared with Bureau of Indian Standards (BIS) and the fuel properties of diesel. Results showed that high amounts of FFA in oils produced low quality biodiesel while neutralized oils with low amounts of FFA produced high quality biodiesel. The quality of biodiesel from jatropha and castor oils was improved greatly by neutralising the crude oils.

Abstract Rhododendron honey is a monofloral honey and it is collected from the flowers of Rhododendron species widely spreading over many countries, mainly in America, Turkey, Indonesia, Australia. It is belived that Rhododendron honey treats several disorders and is used traditionally as an alternative medicine. The determination of the chemical characteristics of the Rhododendron honey is essential for public health. In this research, the physicochemical characteristics of Rhododendron, chestnut and flower honey samples collected from beekeepers in Turkey were determined and compared. Physico-chemical parameters such as moisture, acidity, sucrose, invert sugar, fructose/glucose, conductivity, diastase and hydroxymethylfurfural were analysed in each honey sample. According to the results obtained, no differences were found in physico-chemical properties of Rhododendron, honey samples, except from moisture and acidity compared with those of chestnut and flower honeys. In order to differentiate Rhododendron honeys, new methods should be developed. This honey should be reintroduced to medicine and used in pharmaceutical industry

This study aimed to evaluate the physicochemical properties of water, to determine the macro-benthic invertebrates of this ecosystem. The money samples of water are taken (November - May) at three stations at different depths, including a very polluted one at downstream of the Wadi. Several physico-chemical parameters were measured (pH, electrical conductivity, turbidity, BOD5 MES, water temperature and salinity). The Bi-monthly sampling of macro invertebrates revealed the existence of 40 taxa, divided into 4 branches (amphibians, molluscs, arthropods, annelids), made up of 2344 identified individuals, and distributed according to the bathymetry, where the majority are Arthropods with 95.38%. The annelids represent 3.71%, collected mainly at the level of the strongly anthropized site C. Therefore, the distribution of the macrobenthic fauna, depends on the physico-chemical parameters, on the geographical position.Maintaining a standard water quality in this aquatic ecosystem requires continuous monitoring of its physicochemical characteristics.

Abstract Water is a social requirement and an important factor in the ecological balance. Water from wells is good for direct consumption if the soil is not contaminated. The quality of drinking water is regulated by Law no. 458/2002 (transposing the Directive 98/83/EC on the quality of drinking water). The aim of this paper was to assess the physicochemical qualities of groundwaters from Brestea village, commune Denta, Timis County. The water samples were taken in 2015 from 10 functional wells. For the source whose physical and chemical parameters have exceeded the limit values, the monthly monitoring of the water quality (microbiological and physico-chemical properties) has been performed for 2 years. At the same time, the pH of the soil near the water sources was also measured. The results highlighted a good connection between the microorganisms from water and the nitrite, nitrate and ammonium content of water. The information can be further used to identify and eliminate the specific pollutants, areas and pollution sources.
