A method was developed for the determination of silver in blood and urine by L′vor platform furnace atomic absporption spectrometry with longitudinal Zeeman effect background correction.The recoveries of the method were in the rang of 93.7%～100% and 92.7%～101%. The detection limit was 0.4 μg/L and 0.2 μg/L, and relative standard derivation was 8.4% and 3.4%.The proposed method was an accurate,simple and promising way.It is possible to apply this method to perform the detemination of silver in blood and urine for biological montoring in occupational and environmental medicine.
