Q43) National Environmental Engineering Research Institute (NEERI) and the Centre for Development of Advanced Computing (C-DAC) have jointly developed an ‘Electronic Nose’. Consider the following statements with reference to this:
1) NEERI works under the Ministry of Environment
2) ‘Electronic Nose’ is used for environmental monitoring that can help sniff out a variety of volatile organic compounds (VOCs) and odorants at a pulp and paper mill industry
3) It uses an array of sensors that function on the principle similar to that of human olfaction.
Which of the above statements are correct?
Only 2&3
Ans:43)(b) The pulp and paper industry emits a variety of gases, namely, hydrogen sulphide, methyl mercaptan, dimethyl sulphide, and dimethyl disulphide all of which beyond a certain concentrations may adversely affect the environment and human health, This newly developed Electronic Nose helps in continuous monitoring of these gases, overcoming all limitations of the available analytical instruments that are not only expensive and time-consuming.
Besides, it also establishes a correlation between sensory and analytical measurements for the sulphurous odorants generated from pulp and paper industries, tanneries and distilleries.
Nagpur based National Environmental Engineering Research Institute (NEERI) of Council of Scientific and Industrial Research (CSIR) and the Centre for Development of Advanced Computing (C-DAC) of Department of Electronics and Information Technology of the Government of India have jointly developed the ‘Electronic Nose’ for environmental monitoring.
