The transport rate of polychlorinated biphenyls (PCBs) from water to air was followed in a large (50‐m3) artificial pond. The transport rate across the water/air interface during the day exceeded the rate at night and was positively correlated to air temperature. Volatilization is probably responsible for the PCB transfer.
