With the rapid economic and social development of China, the attention to environment issue is higher and higher. Current, toxic and hazardous substances polycyclic aromatic hydrocarbons (PAHs) has been detected in the air, water, sediments of the river (or lake) and soil. Part of these PAHs come from (1) volatile of PAHs in solids phase or liquids phase in raw coal ,(2) raw coal incomplete combustion (3) PAHs hydrolyze in a reducing atmosphere. As the basis of PAHs discharging in the process of coal using, it is necessary to summary extraction, purification, analysis of the PAHs in raw coal, conclude species and content of PAHs in raw coal, analysis the impact factors of PAHs distribution, discovered the deficiencies in current research and the future research direction.
