Abstract: Plant bacterial diseases cause a major loss in the plants with medicinal and horticultural value. A bactericide 2-bromo-2-nitropropane -1,3-diol commonly known as Bronopol has been used to spray on plants having bacterial diseases or to prevent bacterial diseases. The flowers of the plant Catharanthus roseus Linn. have been used to study the effect of bactericide 2- bromo-2-nitropropane -1,3-diol on the germination of pollen grain. The present study reveals the reduction in pollen grain germination and pollen tube length with the use of bactericide 2- bromo-2-nitropropane -1,3-diol.

Abstract: Present investigation attempts to study correlation coefficient of water quality parameters viz physical (pH, EC, TH), major anionic (Ca, Mg) and cationic constituents (TA, CI). The analyses data were compared with standard values recommended by WHO, ICMR and BIS. The correlation coefficient ' r ' among the various quality parameters has been also worked out. The high positive correlation (<r=0.60) was observed in between pH-Mg EC-TH, EC-Cl, Ca-Cl and TH-Mg. Also high negative (< r=-0.60) correlation observed between EC-Ca, TA-Mg and TA-Cl. The analysis is very useful in the rapid study of groudn water quality.

Abstract: E-waste is fast emerging threat to the environment and public health due to th epresence of toxic and hazardous substances such as lead, cadmium, mercury, polychlorinated biphenyles, etched chemicals, brominated flame retardants etc., However, it is an abundant source of materials such as plastic, glass, base metals, precious metals that can be recovered and incorporated into the production cycle. Ministry of Environment and Forests, Government of India notified E-waste (Management and Handling) Rules 2011 which have come in force from 1st May 2012. As an Extended Producer Responsibility, the producer of electrical or electronci equipment shall have the responsibility for environmentally souind management of their end - of-life products. Collection, dismantling, mechanical processing, and metal extraction are the major steps in recycling.

Keywords: Cigarette smoke, Albino rat, Hematological variables, antioxidant- Vitamin E
Abstract: The present study was conducted to determine the role of vitamin E on selected hematological parameters - Total Erythrocyte Count (TEC), Hemoglobin Concentration (Hb, Conc.), Packed Cell Volume (PCV), and Red Cell Indices- MCV, MCH, MCHC in cigarette smoke exposed male wister albino rats. Experimental rats (150-200 g) were kept in standard laboratory conditions and grouped into three sets- Control set (A) was exposed to ambient air Experimental set (B) was exposed to cigarette smoket for 1 hour/day and Experimental set (C) was exposed to cigaretter smoke with pre-exposure supplementation of vitamin E for eight weeks. The results of the present study imply that hematological parameters altered after cigarette smoke inhalation and lead to elevation in TEC, Hb Conc, PCV, while reduction in red cell indices in albino rats. However, cigarette smoke induced hematological alterations are modulated after supplementation of vitamin E due to antioxidant defense mechanism against toxic action of cigarette smoke.

Abstract: The paper reports a detailed study of solid waste generation in Silchar city of India. Per capita total household waste generation of different income groups in different wards were found to be high in high income group (HIG) and low in low income group (LIG). Bio degradable per capita house hold waste generation (HhWG) was nearly doulbe for HIG in comparison to LIG whereas, incase of non bio degradable waste per capita HhWG was more than four times for HIG in comparison to LIG. Per capita household wste generation (HhWG) was found to be 339. 46 gm day-1 and per capita total waste generation was 522.27 gm day-1. Total household waste generation was found to be 54.59 MT day-1, total market waste generation 22.40 MT day-1 and total other waste generation 7.00 MT day-1. Hence the total waste generation was found to be 84.00 MT day-1 and the ratio of composition of total waste generation was- HhWG: MWG: OWG = 65:27:8. For reducing the quantity of waste generation people ' s participation, motivation for waste reduction at source and reuse of used material should be ensured through awareness campaign.

Keywords: Groundwater, status, policy inferences, remedies
Abstract: With a rapid increase in population and improved living standards, the pressure on water resources is increasing day-by-day. A vast majority of groundwater quality problems are caused by contamination, over-exploitation, or combination of the two. According to estimates, it accounts for nearly 80% of the rural domestic water needs, and 50% of the urban water needs. Groundwater is used intensively for irrigation and industrial purposes. Safe water for all can only be assured when access, sustainability and equity can be auaranteed. This paper discusses the various groundwater problems in India, their sources, factors responsible for groundwater pollution, problem due to overexploitation of groundwater and the remedial measures to overcome this disaster.

Abstract: In the present investigation bioaccumulation of mercury in varouis tissues of fish Labeo rohita was carried out. The probit mortality analysis disclosed that 57.074 mg/L mercuric chloride exposure for 96 hrs at LC50 dose for the toxicological studies. The comparative acount of tissue concentration of mercury resulted in that tissue concentraion was higher in brain and kidney upon exposure of LC 50 dose of mercuric chloride. However in controlled unexposed fishes collected from natural waters had well below the admissible level for human consumption suggested by WHO.

Abstract: UBTL and CBP biomaterial residues were found to effectively adsorb Cd (II) from aqueous solution. The equilibrium amount adsorbed, calculated from the kinetic study, was well expressed by the Langmuir and Freundlich equations. The solution pH had a profound effect on the adsorption rate. The results demonstrate the potential of agricultural wastes as a convenient and low-cost adsorbed of heavy metals. Heavy metal removal techniques using such biomaterials would be an effective method for the economic treatment of wastewater.

Abstract: This paper assesses the quality of pond waters for irrigation and bathing purpose around Nagercoil, Kanyakumari district, Tamilnadu during July- December - 2010. Though, in general the values of physicochemical parameters for most of the ponds fell within the prescribed limit, Nalloor pond was found extremely polluted where the dissolved oxygen was depleted to less than 4.0 mg/L. Since ponds are transformed as ecological sinks for pollutants, unique biodiversity and the fresh water reserve are greatly harmed warranting concrete measures to preserve thes wate sources.

Keywords: CDM, Carbon trading, Global warming
Abstract: This paper states the basic concept of carbon trading. Carbon trading is concerned with controlling the emission of green house gases which are responsible for global warming. Kyoto protocol is one of the most important milestone to tackle this global challenge. This protocol divides the nations into Annex I countries which include developed countries who have accepted greenhouse gas emission reduction obligations and Non-Annex I countries which include developing countries who have no greenhouse gas emission reduction obligations. The first commitment period starts from calendar year 2008 and ends in calendar year 2012. India being a developing country has no emission targets to be followed however can enter into clean development mechanism (CDM) projects. CDM projects in India contribute towards teh sustainable development . The climate summit held at Durban has agreed that Kyoto protocol will be extended post 2012 but its precise details are still to be finalized. However, world ' s carbon markets are thought to be ouit of danger of disruption. This summit may prove quite significant in a sign of how widespread the global impact of carbon emissions is and how far reaching the efforts are to reduce them for the projects in India post 2012.
