Survey of nitrate concentrations in domestic vegetables on the market

Nitrate levels were determined by ion chromatography for 1094 samples of market vegetables. The nitrate levels (mean+-standard deviation) of the vegetables are as follows : cabbage (n=189), 679+-453 ppm ; Chinese cabbage (n= 186), 1320+-669 ppm ; head lettuce (n=174), 1060+-480 ppm ; komatsuna (n=19...
