Biomass burning is an essential source of particulate matter (PM) with adsorbed biomarker compounds (aliphatic hydrocarbons, polycyclic aromatic hydrocarbons, hopane and others) in the worldwide atmosphere Simoneit (2002). The role of biomass burning has concerned all around the world due to its contribution emission of PM and gases in the atmosphere and causing the impact on human health and environment (Dennis et al., 2002). Although the molecular compositions of organic matters in smoke...

This results in a system that lacks diversity and security, threatens the health of our citizens, jeopardises the stability of the earth's climate, and robs future generations of clean air, clean water, and energy dependence(1). Clearly, if an energy source is to form a long term stable basis of an economy, it must be renewable (solar, wind, tidal and...
