Abstract:  The content of Ca, Mg, Fe, Se, Zn, Cu of wildness cress in Se-enriched area in Longhui was detemined by method of atomic absorption spectrometry. The results showed that the content of Zn, Cu, Fe, Mg, Ca, Se is 1.4277×10-4, 0.7853×10-4, 90.4767×10-4, 321.8782×10-4, 1313.3938×10-4 , 1.46×10-4μg/g in fresh cress, and 69.01, 9.42, 1066.38, 3540. 66, 14312.92, 0.154μg/g in day cress(water content is 13.4%). Except the content of Zn lower than celery, others element’s content all higher than other common vegetables. The content of Fe is 45 to 7.5 times to common vegetables. The content of Ca is 13 to1. 6 times to common vegetables. The content of Se is 9.7 to 2.4 times to common vegetables.

Key words: method of atom absorb spectrum, Se-enriched area, content
