Delivery time: 8-12 business days (International)
Non Methane Hydrocarbons (NMHC) plays a vital role in the formation process of ozone in urban environment, where vehicle emissions are dominant. Ozone is known for its negative impacts on human health and environment. The objectives of this research were to study; the statistical distribution of NMHC concentrations at two sites in Pinang (one on the Mainland and one on the island); to develop modeling system of NMHC concentrations prediction; to monitor NMHCs concentrations in several places with different development status; to investigate the relationship between NMHC concentrations and meteorological factors (temperature, humidity, wind speed and wind direction); to verify the NMHC emission sources; and to propose suitable actions to reduce the NMHC levels in Pulau Pinang.
