Investigation of a long-term sampling period for monitoring volatile organic compounds in ambient air
Article Abstract:
This study investigates a long-term low flow rate monitoring method for measuring exposure to volatile organic compounds (VOCs) in order to confirm the validity of sampling of VOCs in the environment on a continuous weekly or monthly period. A solid adsorbent was used. The results of the experiment are discussed.

Automotive sources of carcinogenic polycyclic aromatic hydrocarbons associated with particulate matter in the Chesapeake Bay Region
Article Abstract:
This study investigates motor vehicles as the source of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere and source waters of the Chesapeake Bay over the past ten years. The carciongenic PAHs were either degraded before deposition to the sediments or are diluted by coal-derived PAHs that were deposited earlier.

Extraction and quantitative analysis of elemental sulfur from sulfide mineral surfaces by high-performance liquid chromatography
Article Abstract:
This study describes a means for extracting elemental sulfur from sulfide mineral surfaces in perchloroethylene and the subsequent quantitative analysis by high-performance liquid chromatrography (HPLC). Also, the study seeks answers to some unresolved issues about the oxidation process at the mineral surface of acid mine drainage.
