ABSTRACT
Environmental samples collected from oil palm premises were
evaluated for dioxins/furans contamination. The samplings were carried out at
oil palm premises located in Banting (Premise A) and in Teluk Intan (Premise
B), involving two environmental matrices namely ambient air and soil. The soil
samples were collected in the plantations while ambient air samples were
collected in the vicinity of the mills and refineries. The results of the
analyses showed that the level of dioxins/furans in ambient air were generally
higher in oil palm premise located adjacent to industrial establishments. The
concentration levels at premise A mill and refinery located adjacent to
industrial establishments, ranged from 64.14 WHO–TEQ fg m-3 to
131.87 WHO–TEQ fg m-3, while for premise B mill and
refinery located in the rural area, ranged from 9.93 WHO–TEQ fg m-3 to
16.66 WHO–TEQ fg m-3. Meanwhile for soil samples, the
highest concentrations were recorded in soil collected near roads used heavily
by vehicles. The concentration levels of soil samples collected at premise A
and premise B plantations ranged from 1.910 WHO-TEQ pg g-1 dry
weight to 3.305 WHO-TEQ pg g-1 dry weight.

ABSTRAK
Sampel di kawasan persekitaran premis sawit
telah diambil untuk dijalankan penilaian tahap pencemaran dioksins/furan. Persampelan dijalankan di dua
premis sawit yang terletak di Banting (Premis A) dan Teluk Intan (Premis B) dan
melibatkan dua matriks alam sekitar iaitu udara persekitaran dan tanah. Persampelan tanah dijalankan di ladang sawit manakala sampel udara
persekitaran di kawasan sekitaran kilang pemprosesan dan kilang penapisan. Keputusan analisis menunjukkan aras dioksin/furan di
udara persekitaran secara umumnya adalah lebih tinggi di kawasan premis sawit
yang berdekatan dengan penempatan industri. Aras dioksin/furan di kawasan
tersebut (Premis A) adalah daripada 64.14 WHO-TEQ fg m-3 hingga
131.87 WHO-TEQ fg m-3 manakala Premis B yang terletak di kawasan
pedalaman menunjukkan aras dioxins/furans daripada 9.93 WHO-TEQ fg m-3 hingga
16.66 WHO-TEQ fg m-3. Manakala untuk sampel tanah pula, aras yang paling tinggi direkodkan di kawasan tanah yang
berdekatan dengan jalan yang sering dilalui oleh kenderaan. Aras dioksin/furan
yang dicatatkan di kedua-dua ladang Premis A dan B adalah 1.910 WHO-TEQ pg g-1 berat kering hingga 3.305 WHO-TEQ pg g-1 berat
kering.
