Relationship of polycyclic aromatic hydrocarbons (PaHs) from vehicle emission in air particulate and plant leaves From highway roadsides in Johor, Malaysia

摘要

Polycyclic aromatic hydrocarbons (PAHs) produced from the incomplete combustion of the organic and fossil fuel, andudare usually attached to the particulate matter from the emission. Abundance of PAHs occurrence in the atmosphere hasudthe ability to accumulate into vegetation. This study, by using selected species of plants is carried out to determine theudrelationship between the composition of PAHs in plants and the degree of PAHs pollution in the atmosphere to discoverudthe ability of plants to absorb PAHs from the atmosphere. The study is concentrated on 3 toll station along PLUS’ North-udSouth Expressway in Johor. From this study, it was observed that some plants are suitable for absorption of PAHsudpollutant from the environment and suitable to be introduced as a medium for biomonitoring.
