Department of Environmental Sciences was established in 1994, as an independent first post graduate teaching and research department in the state of Uttar Pradesh. The thrust area of the department is to provide quality education to under graduate, post graduate students and undertaking research concerned with the current problems of environmental pollution and its management with its emphasis on the industrial waste water, solid waste and identification of toxins producing algae, ozone depletion and Antarctica ecology. The department is well equipped with the instruments and the equipments for the monitoring of air, water, and soil pollution. More than 250 research papers have been published in international and national journals by the faculty members and research scholars. Research projects from the various funding agencies such as DST, UGC, MoEFCC, UPCST, AICTE, NCAOR, UPCAR, MOES, UPPCB, and CSIR have been awarded and research work of UPPCB funded project is in progress.

The department is regularly organizing seminars/conferences/workshops on important issues of the environment. The department had organized a national conference entitled “Current issues of environmental health, climate change and its management (NCECM-2018)” in collaboration with the Academy of the Environmental Biology (AEB) in October 2018. Environmental events such as Earth Day, World Ozone Day, World Environment Day, World Water Day and tree plantation etc. are being carried out regularly to generate awareness among the masses. Invited lectures by eminent personalities /environmental scientists/ researchers are held in the department to generate interest among the students and also to provide them opportunities for direct dialogue with such personalities. Summer and Industrial training are also provided to the students in the reputed research organizations and industries to understand the advancement and real working in the field of environment. Students passing out from the department are serving in various reputed research institutions and other government organizations such as CIMAP, CDRI, IITR, NBRI, FRI, IARI, TERI NGOs, state and central pollution control boards and in the ministry of environment, forest and climate change, New Delhi. A good number of students from the department have qualified JRF/NET/GATE examinations and have been placed in administrative services and as teaching faculty in colleges and universities in India and abroad.
