中国・天津で大規模な爆発が起きた現場の空気中から高濃度の有毒な神経ガスが検出されていたことが分かった。8月17日夜の国営中央テレビ（CCTV）の報道を時事ドットコムなどが伝えた。
防護服と酸素ボンベを装着した消防隊員らが爆心地に入り、空気中の有毒物質の濃度を測定した。李興華副参謀長は「シアン化ナトリウムと神経ガスという二つの有毒物質の値が最高値に達した」と述べたという。
神経ガスとは、神経に作用する致死性の毒ガスのこと。サリンやVＸガスなどがあるが、今回検出されたのが、どんな種類なのかは明らかになっていない。産経ニュースは、「爆発が起きた倉庫に保管された化学物質が熱、または水に反応した際に発生したものとみられる」と報じている。
朝日新聞デジタルによると、天津市はこれまで現場近くで、猛毒でシアン化ナトリウム約700トンを確認したと公表。大気中で基準値をわずかに上回るシアン化水素を検出したほか、廃水からも基準値を超えるシアン化合物を検出したとしていたが、神経ガスについては公式に説明していなかった。
