The polycyclic aromatic hydrocarbon (PAH) content in sewage sludge and in farm soils were determined by gas chromatography linked to mass spectrometry (GC/MS) with use 2-ethylantracene as internal standards. Twelve PAH were identified in both sludges with naphthalene (<TEX>$0.78{\mu}g/g$</TEX>) being the most predominant in industrial sludge and pyrene (<TEX>$0.26{\mu}g/g$</TEX>) in municipal sludge. The total PAR content in industrial sludge and in municipal sludge were <TEX>$1.74{\mu}g/g$</TEX> and <TEX>$1.19{\mu}g/g$</TEX> respectively. PAH were contained in paddy soils and the concentration were very low in the range of <TEX>$0.01-0.04{\mu}g/g$</TEX>. The total PAH content in industrial and in municipal sludge were about 9.2 times and 6.3 times greater than in paddy soils (<TEX>$0.19{\mu}g/g$</TEX>).
