EPA proposes banning cancer-causing chemical used in automotive care, other products_我的网站

一 | WOBURN, Mass. -- The U.S. Environmental Protection Agency on Monday proposed banning the cancer-causing chemical trichloroethylene, which can be found in consumer products including automobile brake cleaners, furniture care and arts and crafts spray coating. The move would end a nearly four decade battle to ban the chemical known as TCE, which can cause sudden death or kidney cancer if a person is exposed to high levels of it, and other neurological harm even at lower exposure over a long period.EPA’s recent risk-evaluation studies found that as much as 250 million pounds of TCE are still produced in the United States annually. One of the first places the chemical raised concern was in Massachusetts, where it was linked to contaminated drinking water in the city of Woburn. Two locations there were ultimately designated as massive Superfund sites. Monday's news conference was held at one of them, a location which now serves as a transportation center.“For far too long, TCE has left a toxic legacy in communities across America," said Michal Freedhoff, the EPA’s assistant administrator for the Office of Chemical Safety and Pollution Prevention. “Today, EPA is taking a major step to protect people from exposure to this cancer-causing chemical.” Massachusetts Sen. Edward Markey, who has led the effort to ban TCE, welcomed the move. “With this rule, we can see a future where we will no longer be manufacturing, processing and distributing a chemical known to be deadly,” Markey said. “We will no longer be exposing American families, communities and workers to a toxic chemical legacy that leaves questions, cancer and catastrophe in its wake.”Markey called the effort personal, citing his long-time work with Anne Anderson, a resident-turned-activist whose son Jimmy died in 1981 of leukemia.“Since Anne and I met in 1980, we have been partners in the effort to clean up Woburn, to get justice for her son, and to save other families from seeing their children fall sick as a result of contamination,” Markey said. "Thanks to the advocacy of Anne Anderson and the action of the EPA, the era of corporations using communities like Woburn as dumping grounds for toxic TCE is over.” A 1982 lawsuit over the contaminated water supply involved eight Woburn families, including the Andersons. The case garnered national attention and led to the book and movie titled “A Civil Action.” The American Chemistry Council said in a statement that TCE has several important uses in packaging and in formulating products. The proposed rule “is inconsistent with the underlying science,” the council said, calling on the EPA to avoid unnecessarily restricting valuable industrial uses for the chemical. “EPA must base its risk management proposals on best available science, including accurate assessments of exposure," the industry group said. “Where uses of chemistries have decreased over time, this must be reflected in EPA’s underlying risk assessment, because decreased use reduces potential exposure.”Meanwhile, environmental groups praised the proposed rule, which would take effect in a year. “EPA followed the science, listened to impacted communities, and proposed one of the strongest chemical regulations in recent history,” Earthjustice Senior Attorney Jonathan Kalmuss-Katz said in a statement. “Some chemicals are simply too harmful to remain on the market." TCE is used to make refrigerants and in solvents that remove grease from metal parts. It is also used in carpet cleaners, laundry spot removers and hoof polish for horses. The chemical presents an “unreasonable risk of injury to health or the environment” in 52 of 54 uses in industrial and consumer products, the EPA has found.“I am overwhelmed that all of you are here to acknowledge everything that has happened and everything that was bad has turned good,” Anderson said. “I owe so much to you people to keep the fight going, making sure that everybody is safe and that toxic chemicals like TCE will no longer exist.”The proposed ban stems from a major expansion of EPA's regulatory powers under a landmark 2016 law that overhauled rules governing tens of thousands of toxic chemicals in everyday products, from household cleaners to clothing and furniture.The statute authorized new rules for tens of thousands of toxic chemicals found in everyday products, including substances such as asbestos and TCE, that for decades have been known to cause cancer but were largely unregulated under federal law. Known as the Frank Lautenberg Chemical Safety Act, the law was intended to clear up a hodgepodge of state rules governing chemicals and to update the Toxic Substances Control Act of 1976.The 2016 law required the EPA to evaluate chemicals and put in place protections against unreasonable risks. The agency moved to ban asbestos last year and has also proposed banning methylene chloride, perchloroethylene and carbon tetrachloride.__ Associated Press writer Matthew Daly in Washington contributed to this report.。最近，科技圈和币圈的吃瓜群众们，都围在了一个名为Alpha Arena的AI斗兽场前。这不是什么模拟演练，这是真金白银的AI炒币大赛。主办方nof1给六个当红AI大模型，包括通义千问Qwen、DeepSeek、Grok、GPT-5和Gemini 2.5 Pro，每个发了一万美金的本金，让它们在币圈这个真实赌场里比拼。战况突出一个戏剧性。被寄予厚望的GPT-5和Gemini不负众望，稳定发挥，直接亏成了韭菜本菜。它们在10到20倍杠杆的边缘疯狂试探，无论是GPT-5的连续做空，还是Gemini的高频换仓，结果我们都知道了，市场一波动，它们就一路俯冲向深渊。

二 | 真正的戏码在中国开源模型这边。

三 | DeepSeek一度保持领先，没想到，通义千问Qwen上演了一出绝地反超的好戏。在前期保持稳健之后，于10月23日上午正式超越DeepSeek，登顶第一。Qwen一直稳定在40%上的回报率，现在已飙到53%。有网友对这几天的战况做了个简单的线性回归，发现只有Qwen的斜率是稳中向上的，是真的稳。难怪Qwen的团队负责人Junyang Lin也在社交媒体上忍不住感叹，你应该永远对你的模型有强大的信念，人类实在是太蠢了。但老实说，AI炒币这事儿，短期看就是玄学叠加大A和币圈的随机漫步。AI们可能只是运气好，或者运气差。如果说AI炒币的K线图还只是噪音，那么硅谷的真金白银和头部公司的技术选型，就是实打实的信号。就在AI炒币大赛激战正酣时，大洋彼岸的硅谷也传来了一个值得玩味的消息。 Brian Chesky明确表示：我们未在生产环境中使用OpenAI最新模型，原因是…… 爱彼迎Airbnb的CEO Brian Chesky公开表示，他们公司正大量依赖阿里的Qwen模型。他坦言，因为它非常出色，而且又快又便宜。

四 | 他甚至补了一句，他们虽然也用OpenAI的最新模型，但在实际生产中用得并不多，因为总有更快更便宜的替代方案。这事儿最有趣的地方在于，Chesky本人是OpenAI创始人山姆奥特曼Sam Altman的密友。好哥们当着全世界的面，不用自家兄弟的产品，反而选择了中国的开源模型。这一幕简直是硅谷版的真香定律现场。嘴上都是主义，心里全是生意。

五 | 这也完美符合互联网产品的核心需求，谁又好又快又便宜，我就选谁。 Chesky的真香并不是个例，硅谷的务实派们都在拥抱中国的开源模型。最近在当红播客All-in上，硅谷百亿俱乐部成员，著名投资人Chamath也上演了一出好戏。他当着白宫AI主管的面，公开倒戈中国模型。 Chamath说，他的公司已经是亚马逊AI平台的前20大客户，但已经将大量工作需求转向了中国开源模型。

六 | 他的理由同样务实得可怕，中国模型性能确实够强，而且老实说，比美国的OpenAI和Anthropic便宜太多了。这位大佬可不是普通网红，他是Facebook的前高管，创造过将用户数从4500万增长到7亿的神话，那个你可能认识的人的好友添加功能，就是他和团队的创新。当这种硅谷食物链顶端的捕手，都开始用真金白银押注中国模型时，风向就已经变了。

七 | Chamath在播客里明确表示，以DeepSeek、Kimi和Qwen为代表的中国开源模型，正在挑战美国闭源模型的领先地位。不只是商界，学术界也在用脚投票。比如哈佛艺术博物馆就把Qwen集成到了他们公开的AI探索工具里，用来给馆藏的老照片进行自动解说和数据补全，方便学者和公众检索。全球各大高校也经常选择中国的开源模型进行科研实验。

八 | 这种趋势也被媒体捕捉到了。

九 | 华盛顿邮报最近的分析文章标题一针见血，中国现在正在AI竞赛的这个关键部分领先美国。

十 | 报道称，AI热潮始于美国，但中国公司在开源AI技术方面正悄悄超越美国对手。去年，最好的开源模型大多来自美国。而现在，它们都来自中国。

十一 | 在LMArena这个AI盲测竞技场上，来自阿里巴巴等中国公司的开源模型，评分已经高于OpenAI和Meta等美国公司。正如Hugging Face的政策负责人所说，阿里等中国公司发版频繁且质量高，这就是你建立用户基础的方式。 9月阿里在云栖大会上连发7款模型，在HuggingFace的大模型榜单中，阿里通义开源模型不但夺下第一，而且在前十中位居七席，妥妥的中国模型在全球屠榜。这种疯狂迭代的速度，让一个高赞网友发出了灵魂感慨。

十二 | 他表示，感觉所有非中国的AI实验室都像消失了一样。谷歌、Meta、微软已经好几个月没有重大发布了。

十三 | 与此同时，深度求索、阿里巴巴等中国公司却在遍地开花，模型发布快得让人眼花缭乱。

十四 | 好了，让我们再回到这个AI炒币大赛。如前所述，这个比赛目前还有很多槽点。直播这种形式更像是娱乐而不是正经研究，此外比赛周期也较短，System Prompt没有公开，而且币圈的波动本身就充满了巨大的随机性。但是，市场不在乎这个。

十五 | 吃瓜群众已经嗅到了金钱的味道，开始了一场轰轰烈烈的Vibe Investing（氛围投资or者叫玄学投资？）。 Polymarket是一个去中心化版的博彩+数据预测市场，它允许用户用真实资金下注未来事件的结果。在Polymarket上，好事者已经为这场大赛开盘了。这个盘口的标题简单直接，谁会是Alpha Arena AI交易大赛的赢家。你猜大家押谁最多？截至发稿，押注阿里巴巴Qwen的概率高达36%，稳居第一。DeepSeek以28%紧随其后。至于曾经的王者OpenAI，概率只有可怜的3%。

十六 | 要知道因为每个交易者都用真金白银投票，市场价格往往比民调更准。在过去的选举和政策事件中，Polymarket的预测曾多次领先传统民调。你看，吃瓜群众的钱包，和硅谷用脚投票的现实，在这一刻达成了惊人的统一。这场AI大赛最后的赢家是谁，悬念还会继续。但我们或许可以说，中国开源阵营已经取得了阶段性的胜利。
