Combined effect of boron and salt on polypeptide resolutions in wheat (Triticum aestivum) varieties differing in their tolerance

The Indian Journal of Agricultural Sciences (2015)

Ashwani Kumar Shobha Sharma Charu Lata Shital Sheokand NEERAJ KULSHRESHTA

Salinity aggravates toxicity symptoms of boron in wheat. Four wheat (Triticum aestivum L.) varieties differing in tolerance to these stresses were subjected to five stress treatments [control (2.5 ppm B), 50 ppm B + 6 dS/m, 100 ppm B + 6 dS/m, 50 ppm B + 10 dS/m and 100 ppm B + 10 dS/m]. Higher reductions for root length, fresh and dry weight were observed in Schomburgk and HD 2009 varieties at 100 ppm B + 10 dS/m NaCl in comparison to KRL 35 and BTSchomburgk. Results indicated that combined boron and salt stresses significantly increased soluble B and proline concentrations in the roots. At the highest level of stress (100 ppm B + 10 dS/m), maximum proline accumulation was evident in HD 2009 (18.6 mg/g) and minimum in KRL 35 (13.5 mg/g). Protein profile expressions of boron tolerant and intolerant varieties of wheat showed de novo synthesis of two specific polypeptides (35.73 and 31.10 KDa) in boron tolerant variety and one (16.98 kDa) in boron intolerant variety. Likewise, KRL 35 (salt tolerant) showed 4 specific polypeptides of 89.13, 58.4, 46.21 and 31.10 kDa, whereas three specific polypeptides (24.05, 19.13 and 17.52 kDa) appeared in the salt intolerant variety (HD 2009). Appearance of 5 common polypeptides bands of MW 89.13, 53.4, 46.21. 31.10 and 25.12 kDa in both the tolerant varieties, i.e. BT-Schomburgk (boron tolerant) and KRL 35 (salt tolerant) is of special interest and could have possible use as markers for tolerance. The synthesis of common polypeptide of MW 25.12 kDa was observed in all the four varieties with increase in stress treatments.

IMPLICATIONS OF TEXTILE DYEING AND PRINTING EFFLUENTS ON GROUNDWATER QUALITY FOR IRRIGATION PURPOSE PALI, RAJASTHAN

European Chemical Bulletin (2014)

Jaya S. Ratthore Vimla Choudhary Shobha Sharma

Normal 0 The dyeing and printing of cotton and synthetic fabrics constitute highly specialized industries at Pali. Pollution of surface water stream has always implicit effect on groundwater quality and river Bandi is no more an exception. The primary and foremost cause is the release of untreated effluents in the river by the industries at Pali city. The sodium salts of chloride carbonate, bicarbonate and sulphate are the major pollutants which have increased significantly in polluted groundwaters besides dyes and organic substances. The application of polluted groundwater (salinity >8000 µS/cm and SAR >30) in agriculture fields has reduced the yields of crops considerably. The majority of well waters (67.92%) are characterized (Group V classes) with very high to excessive salinity and sodium hazard (C5S3, C5S4 & C5S5)

Nitrate Ion Contaminated Groundwater: Its Health Hazards, Preventive & Denitrification Measures

Raaz Maheshwari Bina Rani Anju Sharma Rajesh Kumar Yadav Shobha Sharma

The occurrence of high nitrate levels in groundwater has to be recognized as a threat to human and animals. Infant methaemoglobinaemia and nitrate poisoning in livestock occur at unexpected times and places. An important reason is that nitrate concentrations are variable, particularly under extreme climatic conditions. All instances of nitrate pollution related to anthropogenic sources can be managed to reduce or eliminate nitrogen inputs and for protecting groundwater resources. Hence the purpose of this manuscript is to present the facts related to the health hazards, describe processes leading to nitrate pollution of groundwater, and to present strategies to eliminate nitrate pollution.

Groundwater quality assessment at Pali, Rajasthan (India).

Journal of environmental science & engineering (2009)

Jaya Rathore S. S. Jain Shobha Sharma Vimla Choudhary Anju Sharma

Chemical analysis of groundwater samples collected from Pali, Rajasthan (India) showed the direct impact of textile effluents on its quality. Textile printing and dyeing units discharge large volume of effluent per day through lined and unlined channels directed towards the Bandi River. It was observed that the groundwater upstream at Pali has dissolved oxygen (4.06-4.26 mg/L), low salinity (2020-3350 microS/cm), sodium (400-600 mg/L), chloride (545-496 mg/L) and sulphate (88-300 mg/L). It was found that groundwater downstream at Pali is oxygen deficient with dissolved oxygen (0 mg/L), extremely saline (7050-28000 microS/cm), alkaline (330-1430 mg CaCO3/L), rich in sodium (1300-7130 mg/L), chloride (61-818 mg/L) and sulphate (466-4006 mg/L) exhibiting high chemical oxygen demand (153-1788 mg/L). Most of the wells had greenish tinge in water and high salinity. Most of the polluted water had sodium adsorption ratio value above 20 which in combination with high salinity is responsible for reduced crop yield, and low soil permeability has been observed in the affected area.

Noise Pollution: An Annoyance to Endurance

Raaz Maheshwari Magan Prasad Rajesh Kumar Yadav Shobha Sharma Bina Rani

The number of people dying in urban India due to deteriorating air quality is rising every year and very little is being done to deal with pollution in Indian cities. Pollution is a noun derived from transitive verb ‘pollute’, which according to Random House Dictionary of English Language means: to foul, to pollute the air, etc. An important component of air pollution which is assuming importance is the Pollution from Noise. Noise is an inescapable by product of industrial environment, which is increasing very fast with the advancement in industrialization. The Industries located in the residential areas such as the printing press, agro based industries, automobiles repairing, grinding mills, etc. are the main sources of community noise affecting public continuously living in the vicinity. In this short communication, nuisance, adverse impacts and some remedial measures of noise pollution are delineated concisely.

Removal of Rhodamine-B from Aqueous Solutions using Low Cost Adsorbents

International Journal of Chemical Sciences (2015)

Nikita Choudhary Sanwal Ram Ashvini Sharma Shobha Sharma Vimla Chowdhary

Colored wastewater damages the esthetic nature of water and the photosynthetic activity of aquatic organisms. Dyes are widely used as coloring agents in various industries, such as plastics, textile, and paper & pulp industry. In the present study, 1:1 ratio mixture of some low cost materials like activated carbon and fly ash mixtures were used for the adsorption of Rhodamine-B. Batch method was employed for this study to explore the feasibility of using activated carbon and fly ash mixture as a low-cost biosorbent for the removal of Rhodamine-B from aqueous solutions. The effect of physico-chemical variables such as dose level, solution pH, initial dye concentration, contact time, and temperature was also investigated. Both the isotherms, Langmuir and Freundlich models exhibited excellent fit to the equilibrium biosorption data. The maximum monolayer biosorption capacity of 82.6 was attained at optimum pH (6.0), adsorbent dose (5 g), initial dye concentration (50 ppm), temperature (35oC), and contact time (150 min), which was higher than those of many other sorbent materials.
