The FBI confirmed on Wednesday a letter addressed to President Barack Obama has been preliminarily tested positive for ricin but the authorities have not found a link to Monday's Boston bombings.

The letter arrived on Tuesday, the same day that another letter addressed to a US senator was intercepted and initially tested positive for ricin, a highly toxic substance.

The incidents came one day after two explosions occurred near the finish line of the Boston Marathon, killing three people and wounding over 170 others. The authorities have called the Boston bombings an "act of terror," but the motives and perpetrators remain unknown.

美國聯邦調查局(FBI)星期三宣佈,通過初步檢測,在一封郵寄給美國總統奧巴馬的郵件中檢測出蓖麻毒素。但當局並未發現這起事件與星期一的波士頓爆炸案之間的聯繫。這封信是星期二送達的,而在同一天,在截獲的一封郵寄給美國參議員的信件中檢測出了一種劇毒物質—蓖麻毒素。

這起事件發生在波士頓馬拉松爆炸案一天之後,這起爆炸案造成了3人死亡,170多人受傷。當局表示波士頓爆炸案是一起恐怖襲擊,但這起爆炸案的動機和疑犯依舊是個謎。

  【講解】

“ricin”解釋爲蓖麻毒素,最強烈天然毒素之一,如果吸入或吞服,致死劑量僅爲1毫克。“Boston bombings”是指波士頓爆炸案,美國波士頓馬拉松15日發生連環爆炸,共造成3人死亡,其中包括一名中國留學生,170多人受傷。
