1-Introduction
Climate change arising due to the increasing concentration of various greenhouse gases of anthropogenic origin has emerged as a serious global environmental concern and posses a threat and challenge to mankind. Carbon dioxide is the most important greenhouse gas present in the atmosphere. The global warming due to infra red active gases like O3, CFCs, CH4, N2O etc. is collectively as much as that due to CO2 alone (Jain et al.1). Accurate knowledge of the behaviour of its concentrations is thus vital to establish its effect on living beings. From …show more content…
It may be concluded from the Figure that during most of the sampling weeks, vehicular site (Rudrapur bus station) witnessed the highest CO2 concentration followed by the industrial site (Integrated Industrial Estate, Rudrapur). Near Rudrapur, the traffic density remains reasonably high during entire day period. The smoke coming out from the vehicles contains a larger amount of carbon dioxide due to combustion of petroleum in the engine of vehicles. These resulted in the increased CO2 concentration at the vehicular site. Similar findings were also reported by Gratani and Varone5, who found highest CO2 concentrations during times
