Abstract
|
|
|
|
The quantitative analysis of nitrate and nitrite in rain, milk and infant formula was done by Ion Chromatography. The nitrite was not detected(＜O.1 ㎎/L) in all the samples. However, the nitrate was detected in the range of 0.1~4.9 ㎎/L in rain, 9.8~19.8 ㎎/L in milk, and 80~300 ㎎/L in infant formula, respectively. Some content of nitrate is close to the maximum contaminant level(MCL) which is 10 ㎎/L as NO₃-N, 44.3 ㎎/L as NO₃.
