Studies of Physicochemical and Some Heavy Metals in Soil and Lake Sediments

The present work attempts to establish the distribution of Iron, Manganese, Zinc, Copper, Boron and molybdenum and physic-chemical properties of the soil and lake sediments in Bijapur district. The area under study receives domestic raw sewage from surrounding populated neighborhoods through rain water, main tributary of the lake. Concentrations of heavy metals in soil are compared with many guidelines to predict status of pollution. KEYWORDS: Heavy Metals, Lake sediments, Pollution, Soil Samples, etc INTRODUCTION In many developing countries, the expansion of urban centers is of considerable importance for socio-economic growth and this continuously modifies the physical, chemical and biological composition of our living environment MATERIAL AND METHODS Data collection and analysis-10 soil samples (three replicates) were collected at surface level (0-10 cm in depth) were collected from various locations. The collected samples were air dried and sieved into course and fine fractions. Well mixed samples of 2 g each were taken in 250 mL glass beakers and digested with 8 mL of aqua regia on a sand bath for 2 hour

Determination of Physicochemical properties and Escherichia Coli in water

The contamination of processed or unprocessed drinking water by fecal coli form bacteria has been reported worldwide. Despite a high incidence of waterborne diseases, entero-Escherichia Coli is an under acknowledged pathogen of concern to public health in India. Although the presence of EHEC is recorded in surface water resources of India, drinking water sources are yet to be investigated.The drinking water quality with respect to bacteriological examination by quantitative determination of total coli form and fecal coli form count (MPN) and presence or absence for E.coli were done for 21 numbers of drinking water (well, T.E. supply, pond and tube well )samples Hunagund and Badami taluka of Bagalkot district Karnataka areas where cases of dysentery and diarrhea were found to be maximum. Standard methods were used for analysis of total coli form and fecal Coli form bacteria

Assessment of Fluoride Content in Ground and Surface Water and its Environmental Impacts at Basavan-Bagewadi and Muddebihal Taluka of Bijapur District, Karnataka, India

An investigation was undertaken in 10 villages (28 samples) of Basavan-Bagewadi taluka and 11 villages (38 samples) of Muddebihal taluka of Bijapur district to assess fluoride and other physicochemical parameters. And also to assess the clinical symptoms like dental and skeletal fluorosis, joint pains and gastrointestinal diseases and to find out the severity of the disease. A check list developed with the help of available literature and in consolation with nutritionists was used to record clinical symptoms. A sample survey was made after examination for both sexes between the age of 8-50 years at Basavan-Bagewadi and Muddebihal taluka. Fluoride content varies from 0.40-6.40 mg/L and 1.10-7.10 mg/L. However 12 samples were within the range, while 16 samples were above the permissible limits at Basavan-Bagewadi Taluka where as in Muddebihal taluka all the values are above the permissible limits of WHO respectively. The results show that, out of the 2992 examined 824 (25.89%) people have dental and skeletal fluorosis, 274 (9.15%) people have joint pains, 167 (5.58%) have gastrointestinal discomfort and excessive thirst at different stages in Basavan-Bagewadi taluka. Among 2696 examined, 812(29.49%) people had dental and skeletal fluorosis, 432 (16.18%) people had joint pains, 415 (15.54%) people had gastrointestinal discomfort and excessive thirst at Muddebihal taluka of Bijapur district

Assessment of Soil Fertility of Grape Field at Bijapur District, Karnataka, India

Assessment of soil fertility at Bijapur district (Karnataka, India), grape yard of various localities was undertaken. Grape is an important fruit crop of northern parts of Karnataka and it is grown over 9000 hectors. The survey includes 15 grape yards and surface soil samples up to depth of 30 cm were collected and after drying were passed through 2 mm sieve. The soil samples were analyzed for various attributes. The data on analysis revealed that the soil was clay in texture which is considered quite fit for grape growing. The soil pH of various grape fields ranged from 7.2 to 8.8 slightly above the optimum range. The electrical conductivity values varied from 0.18 to 1.75 dS/m well below the critical concentration. The carbon content ranges from 0.23 to 1.01 kg/ha. The available nitrogen was in lower range 45 to 337.5 kg/hector. This might be due to high range of mineralization due to high temperature (dry zone) and loss of nitrogen in the form of ammonia. The soil available phosphorous content range from 15.00 to 48.9 kg/hector which was medium in range. The available potassium ranged from 115 to 592 kg/hector which were high range in all the grape fields
