DAV College Jalandhar organized an Extension Lecture on “Green Chemistry for Sustainable Development”

Jalandhar 10 April (Jaswinder Azad)- Post Graduate Department of Chemistry, DAV College Jalandhar organized an Extension Lecture on the Topic “Green Chemistry for Sustainable Development” under the aegis of S S Bhatnagar Chemical Society.
Dr. Ganga Ram Chaudhary, Associate Professor, Department of Chemistry & Center of Advanced Studies in Chemistry, Panjab University, Chandigarh was the Resource Person. The extension lecture was catalyzed and financially supported by NCSTC, DST, GOI & Punjab State Council of Science & Technology, Chandigarh under NSD-2018 programme with a theme “Science & Technology for Sustainable Future”.
The resource person, Dr. Ganga Ram Chaudhary, was formally welcomed by Prof. T D Saini, Vice–Principal, Prof. C K Sikka, HOD Chemistry Department and Dr. Rajeev Kr. Sharma. Dr. Ganga Ram Chaudhary is actively engaged in the synthesis of nanomaterials via green methods and explore their potential applications for the elimination of contaminants from wastewater, as catalyst and as electrochemical sensors. He is investigating the applications of pure as well as aqueous/ non-aqueous mixtures of room temperature ionic liquids in removal of dyes and other contaminations from their aqueous solution.
In his lecture Dr. Ganga Ram Chaudhary told that Green Chemistry is also called Sustainable Chemistry, which encourages the design and processes that minimize the use and generation of hazardous substances. Green nanotechnology refers to the use of nanotechnology to enhance the environmental sustainability. It includes making green nano-products and using nano-products in support of removal of water contaminants. He discussed the use of Nanotechnology in the fields of removal of arsenic and other heavy metal ions from polluted water, removal of various air contaminants, conversion of toxic gas into non toxic gases, production of gas sensors, neutralization of hazardous chemicals and removal of germs and other harmful chemicals.
In his lecture Dr. Ganga Ram Chaudhary said that in world there is 71% water and out of which only 3% is safe for drinking purpose. 20% of the world population do not have access to safe drinking water and 5-10 million people die annually because of drinking polluted water. He told that according to World Health Organization (WHO) everyone has the right to a safe drinkable water and sanitation service that is physically accessible within, or in the immediate vicinity of the household, educational institution, workplace or health institution. According to WHO, the water source has to be within 1,000 meters of the home and collection time should not exceed 30 minutes.
Dr. Ganga Ram Chaudhary talked about various types of contaminants in water like dyes, heavy metals, chemical toxicity, bacteria. He told about his research work on to removal of dyes from waste water. Many industries such as textile companies, dye manufacturing industries, paper and pulp mills, tanneries, electroplating factories, distilleries, food companies, cosmetics etc releasing dye containing contaminants in the water bodies and make water un-safe for drinking. Dye-polluted water can cause great damage to the human body, functions of kidneys, reproductive system, liver, brain, nervous system,  allergy reactions, dermatitis, skin irritation, cancer and mutation both in babies and grown-ups. He talked about his research work that how his research team is involved in schematic synthesis of metal oxide Nano Particles for developing various techniques for removal of dyes and metal ions from contaminated water for making it safe for drinking purpose. He told that he has got sanction of UGC Project with Indo-US Partnership under programme on ‘Green Chemistry/Engineering and Technologies Education Research and Outreach for Sustainable Development’ for development of such techniques. Principal, Dr. S K Arora encouraged the M. Sc. Chemistry students for further studies and to choose research in chemistry as carrier for working in the field of environment protection.
Dr. Rajeev Kumar Sharma thanked the Resource Person. Prof. C K Sikka, Prof. Sarita Sharma, Dr. Rajeev Kr. Sharma, Prof. Sheetal Aggarwal and Prof. Tanu Mahajan were present in the Extension Lecture.
