今年５月中旬，路过去年丹凤“９．２９”剧毒氰化钠泄漏事件发生地的铁峪铺镇化庙村时，我下意识地去泄毒地点仔细看了看。这一看，不由使我生出几份欣喜。原来，在距泄毒地点３米左右的铁河上游细小的流水中，竟有无数黑色的小蝌蚪时聚时散，四处游欢。那么，这“喜”从何来? In mid-May of this year, when I passed the iron valley shop town of Miaoyu where the Danfeng Phoenix 9.29 poisoned sodium cyanide leak occurred in the past year, I subconsciously went to the venomous spot and looked it carefully. This look, could not help make me give birth to several happy. It turned out that in the small distance of about 3 meters away from the toxic sites in the upper reaches of the Iron River, there are countless black tadpoles gather when the scattered, travel around. So, this “hi” come from?
