Determination of Lead and Cadmium in Sugar and Cement Industry Effluents of North Karnataka

The  aim of this study is to assess the extent of lead and cadmium contamination in effluent released from sugar and Cement Industries in north Karnataka. Physicochemical analysis of effluent reveals that the concentration of lead (0.05mg/l)and cadmium(0.01mg/l) is greater than the permissible limit. The effluent as well as contaminated water is extensively used for the irrigation and drinking purposes in the surrounding areas. Several studies of heavy metal constituents in molasses and other sugars have been conducted

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

Status of Pesticide Residue in Grapes of Bijapur (Karnataka)

AbstractGrapes grown in Bijapur district (Karnataka) were analysed for pesticide residue content employing multiresidue analysis by gas liquid chromatography equipped with ECD and NPD detectors. All the fruit samples showed the presence of one or the other group of pesticides. Out of 8 samples analyzed only two samples showed pesticide residue content below the European MRL.  The detected pesticides are Chlorothalonil, Chloropyriphos, Monocrotophos, Triazophos, Cypermethrin, Lamda Cyhalothrin, Matalaxyl, Flusilazole, Hexaconazole, Myclobutanil, Penconazole, Propiconazole, Triadimenol, Difenoconazole,  Carbendazim,  Azoxystrobin. On the bases of these studies it is suggested that pesticide residue monitoring should be extended to the grape grown for the supply in domestic market similar to the export quality, which may serve as basis for the future policy in chemical use.

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

Abstract: 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
