The diversity of plankton, apart from contributing towards the sustenance of the ecosystem attributes also serves as indicators of water quality and pollution. Considering the important role the zooplankton play in the aquatic ecosystem, there are many recent reports on the diversity and seasonal © 2013-2019 |IJLSCI www.ijlsci.in | 236 Zooplankton diversity of freshwater lakes of Chennai, Tamil Nadu with reference to ecosystem attributes distribution of this group (Sharma and Uchchariya, 1973; Battish, 1992; Dussart and Defaye, 1995; 2018; Adhikari et.al., 2017; Rao 2017; Sharmila and Dhanapathi,2000).

  • Monsoon Assemblages
    MONSOON ASSEMBLAGES ELEMENTS OF THE URBAN HYDROLOGY OF SOUTH CHENNAI Literature Review Author: Michele Vianello Date: February 2017 ProJect Document Number: OV_Vianello_2017A Monsoon Assemblages sis a proJect funded by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme. Grant Agreement No. 679873. This review looks at the literature regarding the hydrology and the built up environment of South Chennai as well as the different types of knowledge shaped around them. It examines academic papers, books and book chapters originating in a wide variety of disciplines (eg. architecture, social sciences, geography, hydrology) as well as non-academic texts (eg. newspaper articles, official administrative body websites, NGO reports) and maps (eg. from official agencies, academic papers). It particularly attempts to understand how the different monsoonal cycles have been playing a role in shaping the hydrology and the built up environment as well as the different types of knowledge used to interpret them and act upon them, or else how these cycles failed to be effectively captured in the knowledge production. Addressing these themes required to examine a very diverse literature, at times tackling very specific aspects of the issues at hand. A consistent attempt has been made to coherently extract those bits of information and build an overall picture of the area while laying out the context and identifying relevant issues for the Monsoon Assemblages research project. In spite of this, this review does not claim to be a complete investigation on the elements of the hydrology of South Chennai: the objective has been rather that of identifying which gaps, pertinent to the Monsoon Assemblages line of enquiry, will have to be filled as well as scoping the field for the overall research.

Meeting need of water requirements for the population is an arduous task. Although three rivers flow through the metropolitan region and drain into the Bay of Bengal, Chennai has historically relied on annual monsoon rains to replenish its Tanks and Reservoirs as the tanks are silted up or encroached and the river banks are invaded by building activity, drying up due to neglect of tank bunds and loss of their capacity to store rain water, rivers have only source from sewerage water from the buildings and establishments which polluted the river and made it a big surface water sewage system. The area covering Cooum and allied interlinked Kusatalai, Palar and Adayar basins should be considered as Chennai Water supply basin for planning and implementing projects for the future demands by harvesting the monsoon rains in these basins. The concept of watershed delineation in to micro watersheds, use of satellite data bike IRS III(Indian Remote Sensing) and new generation high resolution satellite data has been illustrated in this paper. This paper will make one to understand the past glory of cooum maintained by ancient living people from 5000 years and how our greed to expand without proper hydrological modeling.

  • Phyto-Remediation of Urban Lakes in and Around Chennai
    ISSN: 0974-2115 www.jchps.com Journal of Chemical and Pharmaceutical Sciences Phyto-remediation of urban lakes in and around Chennai G.Priyanga, B.Abhirami, N.R.Gowri* Meenakshi Sundararajan Engineering College, Chennai, India *Corresponding Author: E.Mail: [email protected] ABSTRACT Phyto-remediation is an environmental friendly technique which uses plants to improve the condition of the contaminated ecology by absorbing the contaminants. In this research, we have used Water Hyacinth to remediate the waters of Ambattur, Retteri and Korattur. The removal of Lead (Pb), Copper (Cu), Cadmium (Cd) and Iron (Fe) is examined through a model system. These heavy metals were chosen due to their repercussions under high concentration. Batch treatment method is adopted and assessed for 4 weeks. The parameters are tested using Atomic absorption spectroscopy equipment and the results are compared. The results obtained show that water hyacinth is efficient enough in removing almost 95% of harmful heavy metals from urban lake sample. Key words: Green techniques, Phyto-remediation, Water, Plants, Urban lakes, Pollution INTRODUCTION Water is one of the most important constituents needed by living organisms for their day-to-day survival. Even though water is present abundantly on the earth, only 2.5% of it is available to us as freshwater. One of the most important sources of freshwater is lakes which are getting highly contaminated due to increasing urbanization, rapid industrialization and intensification of pesticides in agricultural activities using pesticides. The pollutants are commonly removed through chemical precipitation, reverse osmosis and solvent extraction. These techniques have disadvantages such as incomplete metal removal, high reagent and energy requirements, generation of toxic sludge or other waste products that again require further treatment if required necessary.
