Department of Environmental Science

The Department of Environmental Science was established in 1985. The Department of Environmental Science was created from the school since 1998. Initially the school functions as research unit and then teaching was started since 1990-91, academic session as ‘M.Phil in Ecology’. In 1998 July, the Department of Environmental science started M.Sc programme. At present the department offers Ph.D, M.Phil, M.Sc degree in Environmental Science. The department has four permanent faculty members and two guest faculties and three non-teaching staff. The major research area are basic and applied ecology, pollution biology, environmental impact assessment, microbiology, Bioinorganic and Environmental chemistry, bioremediation, landscape ecology, geomorphology, remote sensing, resource studies, atmospheric science, environmental toxicology and immunology.

Centre on Environmental Biotechnology at the Department of Environmental Science, University of Kalyani, Nadia-741235, West Bengal was established in June, 2002. The Centre was set up for having primary emphasis on the management of natural resources and abatement of pollution as well as hazardous waste management. In our regular activities we maintain and update our ENVIS Website, publish Newsletters and Abstract volumes in regular intervals. Training, workshop & seminar on related subjects, provide information services etc. Our ENVIS centre Website ( has been reconstructed and modified according to the Ministry guideline.

4. Atmospheric Physics

The features to be investigated are mainly four aspects viz. Thunderstroms electrification and Lightning, Atmospheric dispersion of pollutants, Variability of Indian Summer Monsoon and Risk assessment of the environment due to the presence of the Radioactive radiation/sources. The investigations will largely serve the purpose of project related to practical fulfillment of degree of our M.Sc. and M.Phill. students besides our research activity.

a) Thunderstorm electrification and Lightning:

5. Environmental Chemistry

Fluorescent Molecular Sensors: Design, Synthesis and Applications

The design of fluorescent sensors is of major importance because of the high demand in analytical chemistry, clinical biochemistry, medicine and the environment. Numerous chemical and biochemical analytes (cations, anions, neutral molecules and gases) can be detected by fluorescence methods. The success of fluorescence sensors can be explained by the distinct advantages offered by fluorescence detection in terms of sensitivity, selectivity, response time, local observation etc. Quantitative analysis of trace metal ions, recognition of anions and neutral molecules with the use of fluorescent receptors have become extremely important in the context of environmental and biological applications. The high sensitivity and abundance of fluorophores makes fluorescence technique among one of the most promising tools for chemo- and biosensor development. However, the selectivity of fluorescence molecular sensors remains a significant challenge. Thus new, efficient and reproducible synthetic pathway for expanding number and function of fluorescent receptors is attracting great interest.
So, we are interested in designing multidentate novel small-molecule fluorescent receptors selective for trace, toxic and heavy metals and also artificial DNA cleaving or intercalating molecules that are chemically stable and activatable by photoirradiation. The potential binding sites will be azo, imine, pyridyl, oxime, phenolic etc.
Emphasis will also be given to synthesize some bioinspired fluorophores with amino acid side chain. By means of chemical modification, it is possible to introduce a diverse range of functionalities that does not occur in natural systems and can not be incorporated by genetic methods. The ability to augment the genetically encoded amino acids with new amino acids, for example, amino acids with metal chelating, fluorescent, redox active, photoactive, or spin labeled side chains, significantly enhances the ability to manipulate the structures and functions of proteins inside the cell.


The receptors will be characterised by different analytical techniques including Elemental (CHN) analysis, 1H NMR, 13C NMR, Optical rotation, GC-MS, HPLC, Absorption and Emission etc. The newly synthesized metal complexes will be characterized precisely by different physicochemical techniques including Elemental (CHN) analysis, various spectroscopic analyses (MASS spectra, IR, Absorption, Emission, NMR, ESR, ITC, etc.), magneto-structural studies and single-crystal X-ray diffraction studies. The electron-transfer properties in solution will be investigated by electrochemical techniques e.g cyclic voltammetry, differential pulse voltammetry and constant potential coulometry.

So, this research area is of great academic interest due to the convergence of synthetic chemistry, coordination chemistry, environmental chemistry and their valuable contribution in biology and industry especially in pharmaceuticals and chemical industry.

6. Environmental Toxicology

Environmental carcinogenesis, oncogenes, apoptosis, growth factors, immunotoxicology.

a) Environmental carcinogenesis
Research interests is focus on three major areas:
i)    identifying critical targets and mechanisms involved in the initiation and promotion stages of chemical carcinogenesis;
ii)    exploring novel chemoprevention strategies for inhibiting chemical carcinogenesis; and
iii)    collaborative molecular studies on the relationship between smoking, DNA adduct levels, and susceptibility to lung and other tobacco-related cancers in specific human populations.

b) Immunotoxicology:
Many mechanisms may contribute to immune depression observed following exposure to ionizing radiation, Heavy metal, radiation toxicity.
Addressing the following objectives may uncover and elucidate some of the mechanisms under lying immune depression following heavy metal (lead, nickel & cadmium etc.) radiation exposure.

•    characterization of alterations in peripheral blood mononuclear cell and splenic mono nuclear cell subsets during heavy metal, radiation challenge
•    to investigate the role of apoptosis in injury to mononuclear cells in
•    the peripheral blood and spleen;
•    to determine the role of in regulating different pro- and anti- apoptotic factors in of immune cell death following treatment
•    to measure altered cytokine level in heavy metal or radiation induced environment.

iii) Cell cycle, apoptosis, tumor suppressor genes.
The laboratory is focused on investigating the mechanisms involved in the development of cancer. One major focus is cell-cycle regulation in neoplastic development. We have studied the role of cyclin D1 and other cell-cycle regulators in ras transformation and in the development of chemically induced tumors. We also have developed a model of cell-cycle synchronization in the epidermis in vivo and we are investigating cell-cycle regulation by skin tumor promoters.
The laboratory has directed substantial efforts toward studying the mechanisms by which androgen regulates the cell-cycle machinery and the role of cell-cycle alterations in prostate cancer. We are studying changes in cell-cycle regulation in prostate cancer and cell-cycle alterations in the development of androgen-independent prostate tumors.
In addition, we have an active goal aimed at identifying the genetic targets for kidney and uterine cancer, including genes such as tumor suppressor genes (VHL and TSC-2) genes that regulate the cell cycle (cyclinD, p21, p27 and p16) and genes involved in tumor progression and metastasis (HIF-1 and VEGF)

iv) p53 regulation
The role of the p53 tumor-suppressor gene product in cancer is of particular interest because p53 is the most commonly mutated gene in human cancers characterized to date. Cells that lack a functional p53 cannot undergo cell cycle arrest in response to DNA damage and will enter DNA synthesis with un repaired DNA. The molecular dynamics of the cellular response pathways that involve p53 in response to DNA damage are currently under intense scrutiny. DNA strand breaks, induced by either ionizing radiation or microinjection of a restriction endonuclease, have been shown to lead to an increase in p53. This increase requires the currently undefined gene product(s) that are defective in ataxia-telangiectasia, a cancer-prone inherited disease. The induction of p53 results in either cell cycle delay or initiation of programmed cell death (apoptosis), depending on the cell type. A practical application of a better understanding of this pathway might be the specific induction of apoptosis in tumor cells after exposure to therapeutic agents
