| Abstract: | Increased concentration of ozone in atmosphere is harmful for
human health. Non-methane hydrocarbons are ozone precursor. Effect of
nonmethane hydrocarbons in atmosphere and sources of emission have been
discussed in this research paper. According to survey of government and
non-government institutes, Delhi
is the region of excessive emission of methane hydrocarbons. According to
experimental results of central Road Research Institute, New Delhi the concentration level of
non-methane hydrocarbons in traffic, residential, industrial, power plant and
back ground is 0.1 to 0.9 ppb. Concentration of butane, propane, ethane and
acetylene is 0.987 ppb, 0.965 ppb, 0.897 ppb, 0.756 ppb in June and 0.856 ppb,
0.932 ppb, 0.786 ppb, 0.798 ppb in September serially in traffic region.
Results of comparative studies conclude that concentration of non-methane
hydrocarbons in environment depends upon environmental factors and maximum
concentration of nonmethane hydrocarbons is highest in the traffic region. |
