Delhi has high level of air pollutants
June 22nd, 2011 - 6:14 pm ICT by IANSNew Delhi, June 22 (IANS) Delhi has high levels of air pollutants and ozone and the latter has harmful impact on health and agricultural yield, a study revealed Wednesday.
The Energy and Resources Institute (TERI) is conducting this study to assess the energy and emissions scenarios for various states of India from the year 2005 to 2030.
“Ozone monitoring is presently carried out in few cities only and the results in Delhi show that concentrations have violated the standards. It may cause significant damage to the agricultural yield in addition to its ability to impact human health,” a TERI statement said.
TERI found that cities like Delhi and Ghaziabad violate annual ambient air quality standards for particulate matter concentrations.
“In recent years, few cities have also violated the annual average standard for NOx gases and there is a trend towards its increase. Delhi, Bangalore, Pune, Kolkata have shown higher levels of NOx concentrations mainly because of rapid rise in vehicular fleet,” it added.
The statement goes on to add that among all the pollutants, particulate matter pollution is most widespread in Indian cities and is of prime concern.
“However, pollutants like NOx and Ozone are emerging threats for future and proactive policies would be required for their control,” it said.
