Relationship of Polycyclic Aromatic Hydrocarbons (Pahs) from Vehicle Emission in Air Particulate and Plant Leaves From Highway Roadsides in Johor, Malaysia (Kaitan Antara Hidrokarbon Polisiklik Beraroma daripada Asap Kenderaan dalam Partikel Udara dan Daun Pokok di Pinggir Lebuhraya Johor, Malaysia)
Abstract
ABSTRACT: Polycyclic aromatic hydrocarbons (PAHs) produced from the incomplete combustion of the organic and fossil fuel, and are usually attached to the particulate matter from the emission. Abundance of PAHs occurrence in the atmosphere has the ability to accumulate into vegetation. This study, by using selected species of plants is carried out to determine the relationship between the composition of PAHs in plants and the degree of PAHs pollution in the atmosphere to discover the ability of plants to absorb PAHs from the atmosphere. The study is concentrated on 3 toll station along PLUS’ NorthSouth Expressway in Johor. From this study, it was observed that some plants are suitable for absorption of PAHs pollutant from the environment and suitable to be introduced as a medium for biomonitoring.
Key words: Polycyclic Aromatic Hydrocarbons; pollutant; environment; Johor
ABSTRAK: Polisiklik hidrokarbon aromatik (PAH) dihasilkan daripada pembakaran tidak lengkap bahan api organik dan fosil, dan biasanya melekat pada zarah dari pelepasan. Banyak kejadian PAH di atmosfera mempunyai keupayaan untuk mengumpul ke dalam tumbuh-tumbuhan. Kajian ini, dengan menggunakan spesies tumbuhan terpilih dijalankan untuk menentukan hubungan antara komposisi PAH dalam tumbuhan dan tahap pencemaran PAHs dalam suasana untuk mencari keupayaan tanaman menyerap PAH daripada atmosfera. Kajian ini tertumpu kepada 3 stesen tol di sepanjang PLUS Lebuhraya Utara-Selatan di Johor. Dari kajian ini, pemerhatian menunjukkan bahawa sesetengah tumbuhan yang sesuai untuk menyerap pencemar PAH dari persekitaran dan sesuai diperkenalkan sebagai medium untuk pemonitoran biologi.
Kata kunci: Polycyclic Aromatik Hidrokarbon; pencemar; alam sekitar; Johor
