生活在受微塑料污染的海边可能增加心血管代谢疾病风险

微塑料指的是尺寸小于 5 毫米的微小塑料颗粒。纳米塑料则更加微小。这两种大小的塑料微粒都是由较大型的塑料垃圾通过化学分解产生。饮用水、海产品与空气中都曾检出过微塑料和纳米塑料。海水入侵是一个自然过程,在这个过程中,海水会混合进陆地上的地下水资源之中,世界各地的沿海地区都大量报道了这一现象。研究表明,海水入侵是导致沿海地区地下蓄水层中各种污染物(也包括微塑料)高浓度存在的元凶之一。分析发现,与居住在毗邻微塑料污染水平更低的美国沿海县居民相比,居住在有着非常高的微塑料污染水平的水域沿岸的美国沿海县居民有着明显更高的二型糖尿病、冠状动脉疾病以及中风发病率:调整后二型糖尿病患病率高出 18%,冠状动脉疾病的患病率高出 7%,中风的发病率高出 9%。

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
