Abstract
This study was conducted by using the ICP-AES (Inductively Coupled Plasma - Atomic Emission Spectrometry) to investigate the seasonal changes of copper and manganese content in the raw bovine milk. From July 2003 to June 2004, the milk samples were collected from the two geographical locations, Chungcheong-do and Jeolla-do, in Korean peninsula. Copper (Cu) content was determined in the range of min. 10.10 to max. 21.00 ${\mu}g$/100 mL (13.79 ${\mu}g$/100 mL) in spring, 5.06 to 15.41 (10.17) in summer, 5.04 to 19.70 (10.70) in autumn and 6.96 to 17.90 (12.11) in winter. For manganese (Mn), 3.00 to 8.30 (4.87) in spring, 2.30 to 6.44 (3.75) in summer, 2.81 to 6.04 (3.82) in autumn and 2.25 to 9.02 (4.48) in winter. Those data have shown that levels of copper and manganese was relatively constant but higher in Spring than other seasons, suggesting that the levels were not affected by seasons and different locations in Korea.
