2017年4月1日下午2点,吉林建筑大学的一名学生去学校后身驾校学车,发现一侧空地上被倾倒大量药品。该同学拍下图片(下图),并于4月5日7点34分通过微博爆料。4月5日10点,有记者来到位于长春市新城大街5088号的吉林建筑大学,在该校后身的荒地看到了堆放十余平方米的药品,约30种,感冒、止泻、痛风等治疗各类疾病药物齐全,当中还掺杂着一些保健食品。药品大多标注“OTC”字样,属于非处方药品。通过观察,这些药品全部为过期药物,有效期标注一般都在2016年3月份左右过期,最早的是2015年12月份过期。说起药品,更多的人首先想到的是治病救人,鲜有人会想到,如果处理不当,药品对环境产生的影响则有可能反过来威胁人们的身体健康。伴随着各类药品的广泛使用个,人们开始逐渐意识到,人类如今正面临着一个不容忽视的新型环境污染问题-药品环境污染。我国已成为世界上药品环境污染日益严重的国家。
分析我国药品环境污染日益严重的主要原因及其危害。
