dc.description.abstractLafia-Obi coals, woods and charcoals from Keffi, Marke and Shamagay in Nasarawa State were evaluated for the presence of PAHs using standard methods. 200-mesh size pulverized and saw milled samples were solvent extracted using n-hexane and dichloromethane at 80o and 30o for 48 h and fractionated in alumina column. Both fractions were characterized by gas chromatography and mass spectroscopy (GC-MS) that showed a total of 16 PAHs in the samples. Naphthalene was the highest in amount (0.583mg/kg) in the dichloromethane extract of Lafia-Obi Coal while benzo(g,h,i)perylene was the least in amount with approximately (0.000mg/kg) in n- hexane extract for all sample analyzed except Lafia- Obi Coal (0.001mg/kg) for n- hexane extract. In all the samples, the amounts of PAHs were below their toxic levels. Anti-termite activities of wood samples were investigated by treating the wood extractives from the Shanjini (Pterocapus erinaceus) and Marke (Anogessus leocarpa) on softwoods that are prone to termite attack on the field for 12weeks. The results showed that the efficacy of wood extractives to control termite was higher in Shanjini (Pterocapus erinaceus) than Marke (Anogessus leocarpa) in terms of resistance to termite attack.en_US
