VEHICULAR AIR POLLUTION AND ITS IMPACT ON HUMAN HEALTH: A CASE STUDY ON CHITTAGONG CITY

OBJECTIVES
To analyze the structure of vehicular population

To estimate the annual emission of pollutants (NOx, SOx, CO and CO2) from vehicles

To estimate the emission trends from traffic sources

To estimate afforestation required to minimize the annual CO2 emitted from vehicles

To determine the health effects of traffic pollution.

To suggest some mitigation measures for reducing the traffic pollution.












MITIGILATION

Fuel quality improvement
Traffic regulations and enforcement
Improvement of technology
Strengthen of legal authority
