AUTHORS
Stephen Kudom Donyinah is currently a lecturer in the Department of Chemical/Petroleum Engineering. He holds a Ph.D. in environmental science and engineering from the China University of Geosciences, Wuhan, (2004) and received a master's degree in petroleum geology, exploration, and engineering from the same university in 1996. He obtained his B.Sc. degree in geological engineering in 1990 from the Kwame Nkrumah University of Science and Technology. He was listed in the 
Who's Who
in the 21st century, 2001 edition of the Biographical Center of the United Kingdom. His research interests lie in environmental pollutants and toxic wastes in water bodies as well as energy-related issues. He is an associate member of the AAPG and an associate member of the Ghana Institution of Engineers.
Shihua Qi is currently the head of the Department of Environmental Science and Engineering of the China University of Geosciences, Wuhan, China. He holds a Ph.D. in paleonology and stratigraphy from the same university (1997) and an M.Sc. degree in geochemical exploration (1990). He has published numerous articles on environmental science and related subjects, and his research interests lie in environmental geochemistry of toxic organic matters; geochemical exploration for ore minerals, oil, and gas; and geochemistry of bioarchaelogy.
Qi Fei is currently the dean of the Petroleum Research Institute of China University of Geosciences and is a vice director of the Hubei Petroleum Association. She is also an active member of the AAPG. She holds a master's degree in plate tectonics and paleogeography from the University of Chicago. She also holds a B.Sc. degree in petroleum geology from the Department of Petroleum Geology of the then Beijing College of Geology (1960). She has won many national and international awards in science and technology. In 1993, she was listed in the Scientific Achievement of the 20th century by the Biographical Center of the United Kingdom. She has authored and coauthored many scientific articles published in both national and international journals. She is currently engaged in many international academic programs with institutions in the United States, Canada, Netherlands, Malaysia, and Russia.

The preparation of samples (laboratory methods) was conducted in the School of Environmental Studies, China University of Geosciences, under the supervision of T. Han, assisted by his team of experts. The instrumental analyses were conducted at the State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences. The analyses were supervised by Gan Zhang of the Guangzhou Institute of Geochemistry, assisted by Jianhua Liu.
ABSTRACT
High-resolution record is a recently developed tool for research into pollutants. An undisturbed sedimentary core from Lake Liangzi was analyzed for target compounds that included polycyclic aromatic hydrocarbons (PAHs), organochloro pesticides (OCPs), n-alkanes or aliphatic hydrocarbons, and heavy metals using high resolution. This article focuses only on the PAHs. The analytical results indicated 15 different compounds of PAHs at variable concentrations throughout the sediment core. Fourteen of those compounds were found to be members of the group of PAHs that are classified as harmful. The primary sources of these compounds were established to be anthropogenic, and the heavy industrial city of Wuhan, the capital of Hubei Province, could be a major source of these compounds; deposition from other areas of China was also proven. Transfer and deposition into the lake was shown to be through the atmosphere. The high concentrations at the surface and near surface compare well with both recent sources of these compounds and with the time frame.
