一 | Some three million Vietnamese were affected by direct contact with dioxin in that decade.,14% of the territory of South Vietnam was exposed to this toxin, causing severe consequences for the land and nature. Five thousand square kilometers of mangrove forests were almost completely destroyed; about 10,000 square kilometers of jungle and more than a thousand square kilometers of lowland forests were affected. American troops destroyed 70% of the coconut plantations and 60% of the Gewea plantations; they also changed the ecological balance of Vietnam.,The affected areas lost 18 out of 150 bird species; nearly all amphibians and insects disappeared; the number of fish in rivers decreased, and their composition changed. The microbiological composition of soils was disturbed. Changes in the fauna resulted in the replacement of black rats, which are safe for humans, with other species that were plague carriers. Alterations in the mosquito species composition led to the introduction of malaria-carrying ones. Dioxin: A Permanently Exploding Bomb The large-scale US use of chemical warfare in Vietnam lasted until late 1971. But this war was not over for Vietnam itself, said Professor Andrei Kuznetsov, director general of the Russian Division of the Joint Russo-Vietnamese Research and Technology Tropical Center, in an interview with Sputnik.,“This is because dioxins, once inside the human body, begin to work like an HIV infection. If a person is completely healthy, they do not affect him. As soon as the human immune system weakens and any disease begins, dioxins immediately get integrated into the disease chains and start working in their own way. No one knows just how. They can cause cancer, damage to the liver, skin, respiratory system, and much more. Dioxin pathology is very diverse. And the most tragic thing is that it is inherited through mother's milk. More than a million and a half Vietnamese in the three postwar generations have suffered from it. For an extremely long time, for many generations, dioxins will continue to be passed on from women to their children. Moreover, there is no minimum permissible dose for dioxins,” says Andrei Kuznetsov.,Today, Vietnam faces the ever-present threat that children will be born with a wide variety of defects. To this day, several villages there are closed to the public, where children are born into families with various deformities. There are several specialized boarding schools where children with genetic defects live. Scientists from different countries have been studying the effects of dioxin on soil for a long time, but only in temperate and northern climates. No one has studied its impact in the tropics. There have been no studies on what happens when dioxin molecules enter the soil under tropical conditions, continued Professor Kuznetsov.,“The Joint Russo-Vietnamese Research and Tropical Technology Center is the first and only one to address this issue. It was commonly believed that dioxin molecules were insoluble. Supposedly, humus binds them and they remain in the top layer of the soil. One could bulldoze or even shovel it and burn it. But it turns out that things are different in the tropics. Dioxin molecules bind with various acids in the soil, forming new dioxin-containing molecules that become water-soluble and water-permeable. They mix with rainfall streams, sink into the soil, get transported by subsurface water, and subsequently enter wells, lakes, rivers, and seas hundreds of kilometers away from where they were sprayed. This situation persists in Vietnam to this day. There are several ‘hot spots’; places where, during the aggression, the Americans stored barrels with chemical agents. When they left Vietnam, they shot these barrels with large-caliber machine guns and left them there. For example, this happened in Da Nang, which was one of the largest US military bases. And the same happened at the US military base in Bien Hoa. These two former bases are still the largest and scariest hotbeds of contamination,” said Andrei Kuznetsov.,The expert also noted that the Americans recently have conducted a demonstrative action in Da Nang – and have now begun it in Bien Hoa – to decontaminate the soil to a depth of two meters in those places where barrels with warfare agents were stored. But they don`t check the level of dioxin contamination even within the radius of 200-300 meters from the storage sites. Meanwhile, subsurface water transports pesticides far beyond those limits.,The Mission of Joint Tropical Center The Joint Russo-Vietnamese Research and Technology Tropical Center has been studying the consequences of the US chemical war in Vietnam since its founding. In fact, it was established precisely for this work, noted Professor Kuznetsov.,“We were tasked with determining whether contact with dioxin leads to genetic changes in humans and has a detrimental effect on soil, flora, and fauna. Our conclusion - yes, it does. The results of our work were published and reported to the leadership of Vietnam’s Ministry of National Defense and Ministry of Health, together with our scientific and practical recommendations on combating various dioxin-related effects. At the same time, we noted that the most effective, global way to prevent dioxins from damaging people is to take maximum care of their health. That is, Vietnam needs to invest much more in health care than countries that have not been exposed to this toxic chemical. We cannot yet say when the effects of US chemical warfare will cease in Vietnam. After all, Vietnam is the first and only country to have been exposed to such massive amounts of poisonous substances,” Kuznetsov concluded.。 一副眼镜，轻触镜腿即可拍照搜题，答案以字幕形式投射在镜片上，仅佩戴者可见……AI智能眼镜正成为部分学生眼中的“考试神器”。 近日，华南农业大学通报学生在期末考试中使用AI眼镜作弊一事引发广泛关注。南方都市报、南都大数据研究院记者调查发现，平台租赁商家打出“静音搜题”招牌，甚至提供“特殊升级”服务，并表示300多台眼镜在期末周被大学生租空；社交平台上，不少学生交流使用AI眼镜作弊经验。 南都记者租用实测后发现，AI眼镜确能实现静音搜题。科技发展带来效率提升，伴生而至的技术滥用，管理缺口如何尽快防范、补齐，更值得思考。 蔓延的作弊新宠： 大学生发帖交流考试经验 这个学期，大学生小林的高等数学考试在一副AI智能眼镜的帮助下“过关了”。
二 | 这款眼镜于2025年9月上市，售价3299元，接入了四种AI大模型。
三 | 眼镜镜框内置有微型摄像头，搭载了拍照搜题解题等功能，可以拍摄识别题目，经大模型分析作答后将答案以字幕形式直接投射在镜片上，且仅佩戴者可见。 在社交平台上，不少学生发帖交流使用AI眼镜参加考试的经验，观察看到，有大学生使用AI眼镜参加期末考试，还有人顺利通过中小学教师资格证考试。
四 | 南都记者通过评论区联系到小林，他告诉记者，考试前花了300元租下这副眼镜，租期结束后，因为还有其它考试要应付，他索性购买了一台。为了提高搜题的准确率，他还在二手平台专门花钱购买了一套“调教指令”。 社交媒体不少学生发帖交流使用AI眼镜参加考试的经验。 另一名使用者小李向记者讲述了使用过程中的细节。
五 | 为躲避监考，他使用了一枚配套的操作指环来操作眼镜，“否则只能双手去碰眼镜，在考场上太明显了”。为应付监考老师的检查，他还准备了一副与AI眼镜外形相似的普通粗腿黑框眼镜。
六 | 也有人没能蒙混过关，小张在评论区分享了自己使用AI眼镜作弊被发现的经历。由于“没怎么学”，小张花了近400元租下眼镜和配套指环来应付考试。
七 | 他发现镜片容易反射绿光，特意戴了一顶帽子用来遮挡光线。
八 | 据他回忆，考场上老师盯着他看了很长一段时间，然后走过来让他交出眼镜。
九 | 记者注意到，在交流用AI眼镜作弊经验的评论区下面，也有多名学生表示，AI眼镜作弊，面临的纪律处分将远重于挂科本身。 明码标价的作弊方案： 三百余台AI眼镜租赁一空 由于AI眼镜通常售价较高，不少学生选择租赁。南都记者调查发现，在购物平台上可以直接租赁乐奇等品牌AI眼镜，有店铺甚至直接在商品标题中打出“考试专用”。某二手交易平台上也发布了大量AI眼镜免押金出租信息，不少以“静音搜题”“无声搜题”等为卖点吸引学生。而短视频平台上，也出现不少经营AI眼镜出租的账号。
十 | 浏览发现，针对搜题答题功能出租的AI眼镜主要是乐奇Rokid Glasses和千问夸克AI眼镜S1这两款，此外还有影目INMO、Halliday等品牌智能眼镜。 某二手平台上出租AI眼镜信息。 围绕利用AI眼镜作弊，已经形成了一套完整的商业推广链条。租赁商家不仅熟知如何使用AI眼镜作弊，还会主动向租用者兜售一整套“解决方案”。 针对不同考试场景和需求，商家会推荐相应型号，无论是纸质试卷还是电脑机考，无论仅需在镜片显示小抄还是联网搜题，均有对应产品可供选择。 一名商家针对不同考试场景，推荐不同品牌型号的AI眼镜。 南都记者以租用者身份咨询一名商家时，对方主动介绍，租用的眼镜会配套“遮光贴”遮住拍摄时会亮起的提示灯，甚至建议加价租用操作指环，“用起来更方便”。在购物平台上，大量商家公开售卖此类遮光贴，号称能做到“遮挡且不影响拍摄”。 另一名商家向记者透露了更多经营细节。他表示，期末考试季是出租旺季，手头三百多台乐奇眼镜全部租空，“租机器的基本都是大学生，用来搜题”。眼镜三天起租，租金350元，6月底7月初部分地区甚至加价至500元仍一机难求。该商家还向记者建议，由于考试季租赁需求旺盛、不一定能抢到档期，不如直接以3200元价格买断眼镜，使用后可按原价七折回收，算下来比反复租用更划算。 据他介绍，这批机器在官方基础上做了针对搜题答题的“特殊升级”：信号更稳定，不会频繁断线重连，可下载第三方软件，还配套智能指环和遮光贴。商家表示，官方原版答题准确率一般，“经过我们特殊指令调整后，能大幅提升”。这些“调教指令”同样可以在二手平台上买到，售价5元至69元不等。
十一 | 南都记者以学生身份在某二手平台上租赁了一台乐奇AI眼镜进行实测。
十二 | 这款眼镜通过内置AI助手实现拍照搜题，但破绽也明显：眼镜外观形似普通黑框眼镜，但镜框镜腿更粗、整体厚重。搜题时，虽可以通过快捷指令让AI助手自动执行预设好的指令进行拍照、搜题，但响应速度较慢，也容易出现误触。 记者租赁的乐奇AI眼镜和操控指环。 记者使用该眼镜实测高等数学与英语四级题目时发现，拍摄过程中镜框上的提示灯会亮起，使用普通贴纸遮挡，眼镜立刻提示相机无法正常调用。此外，眼镜相机成像质量一般，部分题目因拍不清楚识别错误，同一题目多次搜题出现答案不一致的情况。此外，镜片在特定角度下还会反射出明显的蓝绿色漏光，记者按照作弊学生分享的“攻略”通过调低亮度来掩饰，投射文字随之变得难以看清。 对学术诚信的挑战： 技术监控与教育宣传并行 AI眼镜作弊已非个案，而是一个正在全球蔓延的现实问题。2026年5月，韩国两场托业考试接连发现考生利用AI眼镜作弊，涉事者成绩作废并被禁考4年。
十三 | 在英国，英格兰考试监管机构负责人于2026年6月公开警告，AI眼镜和智能耳机等设备正被用于作弊，且手段日趋隐蔽。 香港科技大学张军教授、孟子立教授团队曾进行过一场引发广泛讨论的实验：用搭载大模型的AI眼镜完成大学期末试卷，30分钟交卷拿到92.5分，成绩超过95%的人类考生。团队形容，AI眼镜在教育领域的崛起是一把“双刃剑”，一方面，个性化学习等应用可降低教育资源不平等，帮助需要额外支持的学生；另一方面，其作弊可能性正严重侵蚀学术诚信，冲击教育评估体系的公正性。团队在接受媒体采访时呼吁，教育者和政策制定者必须立即行动，建立合理监管机制，制定明确政策法规，同时做好技术监控与教育宣传。
十四 | 在国内，多所高校已全面升级防范措施。7月1日，华南农业大学本科生院发布《关于进一步严肃考风考纪、严禁携带智能设备进入考场的温馨提示》。提示披露，近期校内已发现并处理多起考生违规将智能眼镜等电子设备带入考场并企图作弊的行为，相关考生已按校规严肃处理。提示明确，严禁携带任何具有通讯、存储、拍照、传输功能的电子设备进入考场，包括但不限于手机、智能眼镜、智能手表（手环）、蓝牙耳机、隐形耳机等新型智能穿戴设备。 该校多名学生表示，此前期末考试几乎不设安检，只需将书包放至讲台前即可入场。近期，学校要求考生提前20分钟到达考场，接受金属探测仪全身扫描。监考老师反复提醒不得携带智能设备，还对眼镜、耳部等部位重点扫描，尤其是黑框眼镜会被着重查看。 此前，中南财经政法大学本科生院也发布了关于考风考纪的通知，第三条专门强调“自觉抵制智能眼镜作弊”。而在今年高考前，教育部发布2026年高考预警信息，明确提醒考生携带手机、智能手表（手环）、智能眼镜等进入考场即构成作弊。随后，广东、上海、福建等不少省份要求考生佩戴的眼镜须在视频监控下摘下，由监考员实施专项检查。 也有业内人士在接受媒体采访时表示，随着产品迭代，智能眼镜的外观会越来越接近普通眼镜，功能也会更加智能。
十五 | 如果被用于作弊，监考老师将越来越难以察觉。该人士坦言，目前大多数开发团队更多考虑的是如何做出产品，至于产品可能被用于哪些场景则没有考虑得足够周全。 出品：南都大数据研究院 设计：何欣 采写：南都N视频记者 陈袁。
