The DRS programme, with focus on biogeochemistry and environmental geology came into existence on 23/3/1994 and ended on March 31,1999.During this period, a number of academic activities took place both in the field and in the lab. The mobile laboratory was used extensively for field related activities over a radius of about 350 Km by the participating Faculty, their students and other Faculty and students in the school. Some of the M.Sc. and M.Phil field work requirements for the school students were also done using this vehicle. The major activities related to geochemical, ecological, biological and pollution (air, water and soil) related projects of various teachers and students. Details are given in the full report in our DSA proposal.
The carbon analyser, scintillation counter, and the ultra centrifuge are in regular use. The work station is fully utiliser for the internet connections within the school for all labs and for also with additional terminal, as PC's for various courses.
The success of the programme can be judged from the quality publications of the participating faculty and students details of witch are given under individual teachers listing. Various laboratories in the country has been using our facility from time time eading to collaborative projects with a number of institutions in the country. The programme helped us develop manpower training at various levels-students, young researchers and some technical staff. Focussing on biogeochemistry and environmental biology has led to a number of students thesis both at M.Phil and Ph.D levels on these topics.
Release of additional grant towards the end of the programme helped us add some essential accessories and also upgrade some of the systems such as the Carbon anayser to C and S analyser, increase capacity of the work station etc.
By encouraging some of the younger and newer faculty during this programme, we have been able to get many faculty interested in the Special assistance programme of UGC so that our new proposal for upgradation to DSA level involves, a larger number of faculty than at present.
During this period, we had several visitors to our labs and the participating faculty and students also were involved in many national and international level activities. We also organised a number of seminars/workshops at different levels on topics related to the DRS programme. The achievements of some of the students and faculty will attest to the success of this programme, not withstanding some short comings. A large number of books procured are in the central library of the university for extensive use by the entire JNU community.
A mid term progress of our work presented in the Goa meeting received good appreciation and review leading to the grant and subsequent release of additional funds.
Equipments procured in the programme are housed in a centarlised location in the school and constitute the main part of our central instrumentatiuon facility and accessable to every one in the school. We have also created a separate Nitrogen digestion chamber.
Progress under this programme also helped us revise some of the existing courses and also introduce some new courses such "geochemical cycle", "environmental geology", "limnology", "ecology and sustainable development" etc at various levels.
During the course of research advisory committee meetings, a number of suggestions with respect to academic programmes were made by the members and they were duely implemented over the last five years. Our DSA proposal gives the details of various steps taken in this direction.
Progress under the DRS programme can be farther elaborated under the following headings:
The ongoing DRS programme in our school have centered on understanding the biogeochemical behaviour of a number of representative aquatic systems. A number of rivers such as the Godavari, Jamuna, Gomti, Cauvery, Brahmaputra and the Ganges have been studied during this period. Attempts were made to understand the nature of the organic matter, speciation of some of the toxic metals in the aquatic system and pathways of phosphorous in the sediment-water interface. Efforts were also made, in the light of our original proposal, to investigate some aspects of the paleo-environment particularly the last few hundred to thousand years. For this purpose, the Yamuna river system was used as the study area. Transport and pathway of a number of elements in the environment are largely influenced by a number of anthropogenic factors. One such major factor is the urban solid waste management. Limited studies on these aspects were initiated in this area in the national capital region. Work was also initiated on one of the green house gas emission-methane gas- in natural system- we started measurements in some of the coastal wetlands to identify the missing link in the carbon budget in the ecosystem.
One of the aspects of biogeochemistry that has bearing on a number of global problems is the dynamics of carbon in the ecosystem. We could not address this issue to our satisfaction during the period covered by the DRS.
Some key contribution during this period can be seen from the following widely acclaimed publications on various aspects of Biogeochemistry:

The main thrust of this programme was to study the effects of toxicants on human, plant and animal species at the population and organism level as well as cellular and molecular levels by using the modern methods of recombinant DNA technology.
Highlights of Research Activities in Environmental Biology:
Cell-cell and cell matrix interaction in cellular signaling in response to environmental stimuli
The unifying theme of this project is to unravel the mechanism of toxicity development by the interaction of toxicants with biomacromolecules leading to phenotypic changes like chemically induced cellular transformation or chemical carcinogenesis.
"Environment" does not consist only of the global macroenvironment. Of equal importance is the environment around the tissues and organs within a living organism or what might be called the microenvironment. These macro and microenvironments are not in mutually exclusive compartments but interact intimately with each other. Like the macroenvironment, the microenvironment also has a profound effect on the tissues or organs in a living system down to its most basic unit - a single cell.
In multicellular organisms, the space between two cells or the cellular environment is a complex network of secreted biomolecules. This space is called extracellular matrix (ECM). ECM molecules act as biological glue, adhering to various structures and having a role in numerous cellular functions.
Adhesive interactions between cells and insoluble meshwork of ECM plays a vital role in the regulation of cellular functions, primarily on cellular transformation and programmed cell death as a response of the cells to the environmental stimuli. For last few years my group is working on a novel ECM glycoprotein, hyaluronic acid binding protein, confirming its involvement in signal transduction pathway in transformed cells and tumor tissues (Mol. Rep. Dev., 1994, 38, 69-76; Cell. Mol. Biol. Res., 1995, 41, 467-476; Biochem. Mol. Biol. Intl.,1996, 40, 327-337; Biochim. Biophys. Acta, 1997, 1336, 387-393) . We have purified, characterized this novel protein and finally, cloned and overexpressed the gene encoding HA-binding protein by screening human fibroblast cDNA library (J. Biol. Chem., 1996, 269, 2206-2212). By sequence search analysis, we have established its multifunctional activities as this protein is identical with three other proteins like splicing factor associated protein, cellular protein, which interacts with HIV type 1 Rev and the receptor of gC1q - the complement subcomponent (Gene, 1997, 190, 223-226). As a part of the programme, we confirm its localization on human chromosome 17p12-p13, next to p53, the tumor suppressor gene; supporting our earlier observation on the probable role of this protein on carcinogenesis (Genomics, 1998, 51, 476-477). Recently, Human Genome Organization Committee has assigned the name of this gene as HABP-1. The availability of the gene encoding multifunctional protein HABP-1, its monoclonal antibody and purified functionally active recombinant HABP-1 allow us to continue our research activities to clarify its specific role in cell signalling related to chemical carcinogenesis and programmed cell death.
The facilities generated in the DRS programme have been fully utilized by M.Sc. and Ph.D. students, other research scholars and faculty members. A summary of some of the achievements by our students, given in enclosure-1, will show the extent of success of our efforts towards manpower training. In addition, during the course of the DRS phase, we have been successful in generating a large amount of external funding to sustain our research efforts. But we could not organise training courses for scholars from other institutions due to funding problems. Also, training of a few students from other places could not be regularly organised, though on individual basis our labs were well used by younger generation scholars from many places.

Chemical speciation of heavy metals and their bio availability have been undertaken to access the complexation capacity of some environmental and toxic metals in the aquatic systems with naturally occurring organic legends like humic and fulvic acids thereby ascertaining the pollution potential. Another aspects that has been studied in my lab is the metals profiling of our soil, beginning with soils in Delhi region. No such locational profile is available as of now and it would be environmentally important information from the ecotoxicological point of view. Speciation of metals in the soil environment is being investigated through sequential extraction studies and new sequential extraction schemes have been tried out in order to quantify and standardise them. Based on speciation information, it is proposed to initiate chemical modeling of aquatic systems.

This laboratory is working with the protozoan parasite Entamoeba histolytica which is highly prevalent in the Indian environment and contaminates our food and drinking water. It is the causative agent of amoebiasis in humans. The basic molecular biology of the parasite is being studied with the long-term goal to develop specific chemotherapy. DNA probes are also being used to understand the epidemiology of the disease.
