Over-water and over-land polychlorinated biphenyls in Green Bay, Lake Michigan
Article Abstract:
The polychlorinated biphenyls over the water of Green Bay, Lake MI and over the surrounding land are studied to determine volatilization properties of semivolatile organic chemicals. Experiments are conducted wherein air and water samples are subjected to various filtering and adsorption procedures. A Maxima 820D datasystem is then employed to obtain the necessary chromatoghraphic data. Results show that atmospheric PCB concentrations are more prevalent over contaminated water than over the surrounding land.

Assessing annual water-air fluxes on polychlorinated biphenyls in Lake Michigan
Article Abstract:
The air-water exchange of polychlorinated biphenyls (PCBs) in Lake Michigan was studied in connection with the delivery and removal of semivolatile organic compounds from natural waters. An air-water gas exchange model based on mass transfer coefficients obtained from actual air samples was used to compute the flux of PCBs through the air-side and water-side layers. Results that the PCB fluxes in Lake Michigan is dependent on the water temperature, wind speed and PCB vapor concentrations.

Volatilization of polychlorinated biphenyls from Green Bay, Lake Michigan
Article Abstract:
The volatilization of polychlorinated biphenyls from the Green Bay section of Lake Michigan is studied. Experiments are carried out wherein surface water and air samples are analyzed by means of a series of filtering and decanting techniques and gas chromatography. A stagnant film model is then used to determine the transfer of chemicals across the air-water interface. Results show that the gas transfer flow pattern is from water to air.
