| Abstract: | Studies concerning the concentration of lead (Pb)in Delhi due to vehicular traffic are being
conducted under sponsorship of Ministry of Environment and Forests, Government of india. The
comparison of results of two line source models based on Gaussian formulation are made with
ob~rved lead values at 13 busy intersections in Delhi.
Results have been obtained based on predicted emission rates of lead from vehicular
traffic over next 10 years. Each year the number of vehicles has increased e.g. it has doubled
during the last 5 years.
ii)
Two types of studies have been made:
Hourly lead concentrations due to vehicular traffic in Delhi have been computed using
two analytical line source models ( liT and ISCST ) are based on the Gaussian plume
approach.
Monthly average lead concentrations for the period 1985-2000 have been computed by
use of the Climatological Dispersion Model ( CDM ) and the Industrial Source Complex
Long Term ( ISCLT ) model, both of which are U.S. operationa... |
