一次性电子烟毒性大于传统香烟

一项研究发现,部分一次性电子烟和烟弹释放出的有毒金属含量,超过了老式电子烟,甚至比传统香烟还高。研究称一次性电子烟在一天的使用中释放的最高铅含量,相当于抽了近 20 包传统香烟。研究人员强调,尽管大多数一次性电子烟在美国属于非法产品,但市场上仍然广泛流通。其主要使用者是青少年和年轻人,而他们也正是对铅暴露最敏感的人群。吸入某些金属元素会显著增加癌症、呼吸道疾病和神经损伤的风险。此次研究分析了来自三大主流品牌的 7种 一次性电子烟。研究人员利用仪器模拟吸入 500-1500 次,并检测烟雾中金属浓度。他们发现随着吸入次数的增加,烟气中铬、镍和锑的浓度也随之升高。研究人员还拆解了这些设备,发现部分有毒金属来自烟油本身,也有不少是从加热元件、合金部件中浸出。含铅铜合金组件释放的铅和镍,加热线圈释放的镍,以及原始烟油中高浓度的锑,都是污染来源。

However, analysts are positive on the stock now. “We have seen a huge downside movement in the stock due to the central electricity regulatory commission’s (CERC) order that seems to be negative from 2014-15 onwards but we cannot take a linear negative view on the stock and further downside movement on the stock is unlikely. Currently stock is underpriced. Investors can bet on it for a longer horizon," said Vivek Gupta, director research at CapitalVia Global Research.

How To Find Channels On Telegram?

There are multiple ways you can search for Telegram channels. One of the methods is really logical and you should all know it by now. We’re talking about using Telegram’s native search option. Make sure to download Telegram from the official website or update it to the latest version, using this link. Once you’ve installed Telegram, you can simply open the app and use the search bar. Tap on the magnifier icon and search for a channel that might interest you (e.g. Marvel comics). Even though this is the easiest method for searching Telegram channels, it isn’t the best one. This method is limited because it shows you only a couple of results per search.
