Controlling polycyclic aromatic hydrocarbons emission of peri urban air Jakarta

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the atmosphere and well-known to be carcinogenic and mutagenic. They are products of incomplete combustion. In urban, PAHs are almost entirely anthropogenic. Peri-urban Jakarta was selected as the field of this study where traffic air pollution and its health effects have long been a serious problem due to the heavy traffic and the chronic state of traffic congestion. Previous studies on roadside measurements reported ambient air concentration of the sum of 16 PAHs in particulate at roadside ranged from 3 to 330 ng/m3. Trees have demonstrated feasibility to reduce toxic PAHs from peri-urban Jakarta roadside environments by accumulating particle bond PAHs on their surface area of leaves. Resulted characteristics this study provides interesting technique for controlling the PAHs pollution problem in the peri-urban area of Jakarta and this in turn can be utilized by area which similar characteristic.
