J G Mullaa, Syed Asifb, Syed Abedc, Vidya Pardhand

  • Abstract

    In the present paper we report the ground water quality of Babalgaon Dist. Latur, the water samples were collected from four sampling sites and their physico‐chemical parameters such as pH, conductivity, chloride, sulphate, temperature, turbidity, DO, TDS, COD etc. the water quality is found to be good in some cases but someof the parameters were above the permissible limit.

K.Narasimha Reddy, M.Aruna and S.Satyanarayana

  • Abstract

    The usage of toxic pesticides is harmful to the Human beings as well as aquatic and other ecosystem. Hence this study was conducted to validated analytical method for water and also determines the pesticide residue levels in lakes situated in the heart of the Hyderabad city. In this method organo and herbicides were analyzed on ECD and PFPD and good recoveries were obtained. Water samples collected during 2005 to 2007 from Hussain sagar and Mir Alam lakes detected with pesticides viz., HCH (0.00 – 4.21 μgL-1), DDT (0.00 – 1.13 μgL-1), Endosulfan (0.00 – 0.77 μgL-1), heptachlor (0.00 – 0.128 μgL-1), Dicofol (0.00 – 0-.124 μgL-1), methyl parathion 0.00 – 0.43 μgL-1), Malathion 0.00 – 3.121 μgL-1), and chlorpyriphos 0.00 – 3.12 μgL-1). The total residues were above Maximum Residues Levels (MRL is 0.5 μgL-1).

Ranjana Agrawal

  • Abstract

    Ground water samples analysis of Gangapurcity town were collected during April 2008 to November 2008. 30 ground water samples were collected from different places of Gangapurcity town of Sawai Madhopur district. The quality analysis has been made through the pH, EC, TDS, Total Hardness, Sodium, Pottassium, Calcium, Magnesium, Chloride, Sulphate, Nitrate, Fluoride and Alkalinity. It was found that nitrate concentration was ranging from 5 to 300 mg/l. The concentration remains same throughout the period, irrespective of rain/flood period. The permissible limit by WHO of Nitrate is 40-50 mg/L. High Nitrate concentration may cause blue baby syndrome or methemoglobinemia1

Plastic Waste Management Strategies for Indian Cities

Syeda Azeem Unnisa and Bhupatthi Rao

  • Abstract

    Plastics have been used extensively in both food and water packaging because of their inherent properties such as low bulk densities and inertness that make them convenient carrier materials and low risk contaminants. Plastic bottles and sachets used to package iced water that is sold to people in transit points and in moving vehicles have become widespread in the Andhra Pradesh. However, the packaging revolution has not been correspondingly backed by appropriate plastic waste management policy, which has left many cities in India littered with plastic wastes; thus, creating disgusting visual nuisances and other public health problems. The paper discusses the experiences, challenges and prospects of plastic waste management in Andhra Pradesh and proposes a new model of fractional levy and polluter tax system to address this environmental eye sore. It is concluded that the current rate of environmental deterioration is likely to persist unless a long term remedial such as the polluter taxation system is carefully worked into plastic wastes management schemes in India.
