“男生把坤坤放女生定眼里云开”美媒:研究发男生把坤坤放女生定眼里云开现美国家庭饮用水中或存未知粒子 可能有毒

  中新男生把坤坤放女生定眼里云开网11月22日电 据美国男生把坤坤放女生定眼里云开全国广播公司(NBC)、美国《国会山报》报道,一项新研究发现,约三分之一的美国居民饮用的自来水中含有一种此前未发现的粒子,且可能有毒,引发了人们对潜在公共健康风险的担忧。

  据报道,根据当地时间11月21日发表在《科学》杂志上的一项研究结果,这种粒子被称为“氯硝酰胺阴离子”,是在用氯胺(一种由氯和氨混合而成的化学物质)处理水时产生的。而氯胺常在市政供水系统中用于杀灭病毒和细菌。

  报道称,研究表明,约有1.1亿美国居民(占目前美国总人口数的三分之一)从水龙头中饮用经过氯胺处理的水。

  科学家表示,他们没有确凿的证据表明“氯硝酰胺阴离子”具有危险性,且可能需要数年时间才能确定,但它与其他令人担忧的化学物质有相似之处。
