Mottled ducks (Anas fulvigula) were collected in August 1980 to determine radium-226 (226Ra), lead, arsenic, fluoride, and barium concentrations. The mean 226Ra concentration (3.08 pCi/kg) was greater (P < 0.01) in duck muscle tissues from a phosphate clay settling basin than the mean concentration (0.86 pCi/kg) in muscle tissues from ducks collected in a Lake Okeechobee marsh. There were no differences (P > 0.05) between areas for concentrations of lead, arsenic, fluoride, and barium in muscle tissues. Radium-226 concentrations and physical condition parameters were not correlated (P > 0.05). Concentrations of 226Ra in duck muscle tissues suggest that no appreciable human health hazard exists from eating mottled duck muscle tissues.
