Estimating NOX, VOC, and CO variability over India’s 1st smart city: Bhubaneswar

Volatile organic compounds including benzene, toluene, ethyl and xylene (BTEX) in the atmosphere have severe health environmental implications. These variables are trace elements atmosphere. There not enough measurement analysis studies related to atmospheric BTEX variation globally, even less developing countries like India. The present study analyses variations over an eastern Indian site, Bhubaneswar. continuous of is first its kind 2 years data (2017–2018), attempts find relation with meteorological parameters, significance ratio between components, along transported air masses. To account for pattern emissions association variability Bhubaneswar, we also developed emission details from transportation sector year 2018 analyzed patterns CO NOx 2018. results indicated that concentrations maintained at site via other regions, significant local generation BTEX, which smaller comparison emission.
