“…Seiring dengan peningkatan pengeluaran minyak mentah, maka secara tidak langsung kadar bahan buangan enap cemar minyak yang terhasil daripada pemprosesan minyak juga meningkat. Secara puratanya, penghasilan sisa enap cemar di Malaysia mencecah hampir 50,000 tan metrik pada setiap tahun disebabkan peningkatan kilang penapisan dan pengangkutan minyak di bahagian Selat Melaka (Keshavarzifard et al 2014). Manakala, dianggarkan hampir satu billion tan enap cemar minyak dihasilkan di seluruh dunia (Hu et al 2015).…”

Enap cemar minyak dikategorikan sebagai bahan radioaktif peringkat rendah dan pelupusan sisa ini menjadi isu penting dalam pengurusan sisa. Oleh itu, kajian ini bertujuan untuk menguruskan bahan radioaktif tabii (NORM) yang terkandung dalam sisa enap cemar minyak melalui kaedah pengacaan dan mengkaji kadar larut lesap bahan dipegun sebelum dilupuskan. Kajian mendapati bahawa sisa muatan yang optimum bagi bentuk sisa kaca adalah pada julat 20-25% bt. sisa enap cemar dan 75-80% bt. sisa kaca CRT yang dibakar pada suhu 1200°C. Ujian XRD menunjukkan kesemua bentuk sisa kaca adalah kebanyakannya amorfus dan unsur-unsur bertabur dengan sekata melalui analisis FESEM-EDX. Tambahan pula, pembebasan ternormal adalah rendah dan tidak melebihi nilai penunjuk yang dijadikan rujukan. Bentuk sisa kaca yang terhasil dalam kajian ini menunjukkan kaedah pengacaan boleh menjadi alternatif bagi pelupusan sisa enap cemar minyak yang mengandungi bahan radioaktif.

The distribution, sources, and human health risk assessment of polycyclic aromatic hydrocarbons (PAHs) in surface sediment and the edible tissue of short-neck clam (Paphia undulata) from mudflat ecosystem in the west coast of Malaysia were investigated. The concentrations of ∑ PAHs varied from 347.05 to 6207.5 and 179.32 to 1657.5 ng g in sediment and short-neck clam samples, respectively. The calculations of mean PEL quotients (mean-PELQs) showed that the ecological risk of PAHs in the sediment samples was low to moderate-high level, whereas the total health risk through ingestion and dermal contact was considerably high. The PAHs biota sediment accumulation factors data for short-neck clam were obtained in this study, indicating a preferential accumulation of lower molecular weight PAHs. The source apportionment of PAHs in sediment using positive matrix factorization model indicated that the highest contribution to the PAHs was from diesel emissions (30.38%) followed by oil and oil derivate and incomplete coal combustion (23.06%), vehicular emissions (16.43%), wood combustion (15.93%), and natural gas combustion (14.2%). A preliminary evaluation of human health risk using chronic daily intake, hazard index, benzo[a]pyrene-equivalent (BaP) concentration, and the incremental lifetime cancer risk indicated that PAHs in short-neck clam would induce potential carcinogenic effects in the consumers.
