暴露在汽车阻燃剂下面临更高的致癌风险

2024-05-10 19:00 by 被掩埋的巨人

杜克研究人员发表在《环境科学与技术》杂志上的一项研究称，汽车内的空气可能会受到已知或怀疑能致癌的阻燃剂的污染。制造商通常将这些化学物质添加到座椅泡沫和其他材料中，以满足阻燃标准。研究人员表示，考虑到驾驶员平均每天要在车内至少待 1 小时，这一问题具有重大的公共卫生意义。对于通勤时间较长的人以及儿童乘客来说，这一点尤其令人担忧。研究人员在来自美国各地的 101 辆汽车的车内检测到阻燃剂。其中 99% 的汽车含有磷酸三（1-氯异丙基）酯。这是一种阻燃剂，正在接受美国国家毒理学计划调查，为疑似致癌物。大多数汽车还有其他有机磷酸酯阻燃剂，包括三（1,3-二氯-2-丙基）磷酸盐和三（2-氯乙基）磷酸酯，这两种都是美国加州 65 号提案指出的致癌物质。这些阻燃剂也与神经和生殖系统损害有关。研究人员强调，通过打开车窗并将车停放在阴凉处，或许可以减少车内阻燃剂的暴露，但真正需要的是减少汽车中添加的阻燃剂数量。

Telegram Desktop App Not Working on Windows?

Reinstall Telegram

If all the fixes listed above haven't worked, you may have to reinstall Telegram as a last resort. Reinstalling fixes all temporary glitches, replaces corrupted files from the previous installation, and installs the most updated version. However, before you reinstall it, it's imperative that you uninstall it properly. Follow these steps to uninstall Telegram: Go to the Control Panel. Go to Programs and Features. Find Telegram in the list. Right-click on the app and hit Uninstall. Uninstalling Telegram App in Windows Control Panel After uninstalling, grab a fresh copy of the Telegram app from the Telegram official website and install it. Even the Telegram website may be inaccessible if Telegram is banned in your country. Hence, keep your VPN connected when downloading and installing Telegram. Fresh installation of the Telegram app will hopefully restore it to its original state. If not, you may want to run an SFC scan on your computer, run a malware scan, and update your OS. After attempting all these fixes, if the problem persists, it's better to temporarily switch to Telegram's web client until the issue resolves itself.
