Validasi Dan Distribusi Polycyclic Aromatic Hydrocarbons Pada Tanah Terbakar Mineral Dan Gambut Menggunakan Metode Hplc Di Kecamatan Tampan – Pekanbaru Riau

---

Polycyclic Aromatic Hydrocarbons (PAHs) are pollutants generated primary by combustion that are widely available in the environment, which are carcinogenic and are widely studied in several countries. Forest fires that occur in Riau province have the potential to increase the content of PAHs in the soil. In addition to determining the PAHs content in burned soil, this study also aims to find an efficient and optimum method for determining the PAHs content in the soil.
A simple method for the extraction and determination polycyclic aromatic hydrocarbons (PAHs) from soil by applying the clean-up, and preconcentration technique has been validated with limits of detection, limit of quantification (LOQ) and recovery. Techniques of extraction have been found to influence the content of PAHs. The implemented techniques were Soxhlet, ultrasonication and mechanical shaking and followed by solid phase extraction C-18 (SPE) to clean up and pre-concentrated was investigated. The results were compared to determine the method with the highest extraction efficiency. Chromatographic operation conditions for the separation of PAHs using high performance liquid chromatography (HPLC) using ultraviolet – diode array detector (UV-DAD) equipped with Zorbax Eclipse PAH column, at 30oC, mobile fase combination of of water and acetonitril with flow rate 1,0 mL. Analysis of standard spiked soil blank resulted in recoveries 70 – 107% for ultrasonic, 55 – 110% for mechanical shaker and 57 – 99% for Soxhlet.
PAHs concentration in soil and peat soil samples (taken in Jalan Riau-Pekanbaru) show distribution of less 4-ring ; Nap, Ant and Flt for soil and Nap, Ace, Flu, Phe, Pyr and Chr for peat soil with concentration 35,56-116,35 μg / Kg and 15,05-1325,99 μg / Kg respectively. The 5-ring (BkF and BaP) also found in peat soil ( 22,26 and 35,08 μg / Kg). In burn soil beside low molecular weight PAH less 4-ring also found 5-ring (Bbf) in low concentration (46,52 μg / Kg). In burn soil peat found distribution of large molecular weight of PAHs, the 6-ring BgP (1173,23 - 19493,55 μg / kg), followed respectively by IP (471,00 - 279831 μg / kg), DaA (64,81 - 2014,89 μg / kg), PAH 5-ring with BbF value (9,16-141,52), Bkf (14,43 - 84,16 μg / kg), 4-ring contribution from Cry (78,29-101,49 μg / kg) and Pyr (65,91 μg / kg). The low molecular weight only comes from the contributions from Ace and Flu.
Keywords : Validation, HPLC, extraction, PAHs and burnt soil.
