Se in low-lying area in Yutangba of Enshi, originated from the slightly exposed bone coal shaded by forest in the west halfway up the mountain. In 1958, when the forest was lumbered, the early drought and subsequent rain strengthened the weathering bone coal, water-soluble Se quickly moved to low lying area ; where Se-rich plants grew, thus came the breakout of the Se-poisoning in 1965. The breakout of Se-poisoning in Yutangba results from conbined function of human andnatural egography factors.
