Abstract:
The aim of this study was to determine accumulation of polycyclic aromatic
hydrocarbons (PAHs) in lichen by using high performance liquid chromatography coupled
with fluorescence (FLD) and diode array detector (DAD). The studied PAHs compounds
were naphthalene, acenaphthene, phenanthrene, anthracene, fluorenthene, pyrene, chrysene
and benzo[a]pyrene. The HPLC method was validated by using Accliam C18 column
(4.6×150 mm i.d., 3 μm particle size) at 25 ºC. Acetonitrile and DI water was used as mobile
phase in gradient elution with flow rate 1.0 mL/min. The gradient solvent program began
with 60% of acetonitrile for 3 minutes, then went to 100% of acetonitrile in 15 minutes with a
final hold 5 minutes. The results demonstrated that most compounds had limit of detection
(LOD) from FLD lower than DAD, except acenaphthene and anthracene. The LOD by FLD
showed that naphthalene, phenanthrene, fluorenthene, pyrene, chrysene and benzo[a]pyrene
were 1.70, 1.24, 0.40, 0.50, 0.30 and 0.16 ppb respectively. Whilst, those of acenaphthene,
anthracene were 2.25 and 6.37 ppb. Accordingly, LOD by DAD of acenaphthene and
anthracene were 1.45 and 1.50 ppb. The linearity (in term of correlation coefficients, r2) of
eight PAHs were higher than 0.9998. Sample preparation for analysis of PAHs in the lichen
Parmotrema tinctorum were carried out by sonication extraction using hexane and followed
by solid phase extraction. Cleaning-up process consisted of florisil mini-column, previously
rinsed with 30.0 mL of acetonitrile and then conditioned with dichloromethane and hexane.
The suitable solvent for elution was the mixture of hexane and dichloromethane (65:35). The
sample preparation method was validated by precision and spike recovery. The results of
precision (%RSD) were lower than 5 % and recoveries of the spiked PAHs in the lichen were
within the ranges of 85- 95 %.
