In this study, some heavy metals concentrations (Zn, Pb, Fe, Mn, Cu, Ni) and other physico-chemical parameters were studied
during October 2001 to September 2003 in Karanja reservoir, Bidar district. Water quality parameters were collected monthly
basis whereas heavy metals were analyzed by Atomic Adsorption Spectrometer (AAS). Heavy metals have shown within the permissible
limits, except Fe and Ni were recorded higher values in southwest monsoon, where as Mn has showed higher concentration in
northeast monsoon in and summer. All other physico-chemical parameters are with in the permissible limit. Water is moderately
hard and reservoir is productive. 相似文献

The plovers Charadrius hiaticula and C. alexandrinus feed on the mysid shrimp Gastrosaccus sanctus (van Beneden, 1861). They hunt at random along the sandy seashore, on the sites of the densest mysid population, regardless of the size of the mysids. 相似文献

Samples with the best adsorption properties are selected as a result of investigations conducted on synthesis of manganese-dioxide-based materials and study of their physicochemical properties. Materials were selected on the basis of their low cost and the simplicity of their production technology. In the laboratory the synthesis and analyses of materials was carried out for selected samples. The sorption of a series of elements is studied for a more detailed investigation of materials obtained. The results obtained will promote the synthesis of materials with improved adsorption properties with the aim of their application for purification of water from strontium. It is shown that the most promising way for amendment of manganese oxide is modification of this material using acid-resistant oxides. These oxides are also less expensive than existing sorbents for strontium. 相似文献

Groundwater quality of Gulbarga District is extensively monitored for two years of study period from October 1999 to September
2001. Twenty-five different sampling stations were selected for the study purpose in the city and five selected villages in
the district. Gulbarga districts lies in the northern plains of Karnataka State, covers an area of 16,244 km2 and lies between 16°-11′ and 17°-19′N latitude and 76°-54′E longitude The study revealed that the water sources in the area
are heavily polluted. The major water quality parameters exceeding the permissible limits during all the seasons are total
hardness, calcium hardness, magnesium hardness, alkalinity and MPN (Bacterial count) and other parameters have shown distinctive
variation in different stations and season. Most of these parameters are correlated with one another. Statistical analysis
of the data is presented. 相似文献
