2011年,福岛核电站事故发生后,大量放射性物质泄漏到大气层和太平洋,对周围环境造成了难以逆转的伤害,数十万人被迫撤离该地区。时至今日,作为日本邻国之一的韩国仍未解除福岛海鲜禁令。
日本以核污水存储能力即将达到上限为由,在2021年4月13日,正式决定将福岛第一核电站核污水排入太平洋。过去一年多,日本政府和东京电力公司一直在持续推进核污水排海计划。
日本政府辩称,这些核污水经多核素处理系统(ALPS)处理后很安全,甚至“可以喝”,这样的表态无疑在愚弄大众。
事实上,经过处理的核污水仍含有多种放射性物质,核污水一旦排放入海就无法回收,长期来看,将会给海洋生态带来难以估量的潜在威胁,最终危害人类健康。
因此,核污水排海计划推出后,遭到日本民众强烈反对。日本《朝日新闻》2022年3月公布的问卷调查显示,福岛县、宫城县和岩手县受访的42个市町村长中,约六成反对东京电力公司福岛第一核电站核污水排放入海。日本全国渔业协会联合会也多次申明立场,反对该计划。
日本政府认为,核污水排海是最便宜、最省事的解决方案,但此举却将周边国家乃至全世界置于核污染风险中。太平洋非日本一家之海,核污水会随着洋流流动,其影响势必会跨越国界,危害周边国家乃至整个国际社会的公共福祉和利益。
《韩国经济新闻》发文称,相关研究认为,福岛核污水如果排放入海,约7个月后将到达济州等韩国海域,该国水产业和旅游业将遭受相当大的损失。
德国南极海洋机构也曾发出警告,若日本将所有核污水排入海中,不到半年,整个太平洋都将面临高度辐射威胁,包括远在大洋另一端的美国。太平洋地区人民更是对日本该计划持反对意见。
日本作为《联合国海洋法公约》缔约国,有义务保护海洋环境。然而,在核污水排海方案的正当性、核污水数据的可靠性、净化装置的有效性、环境影响的不确定性等问题上,日本未能作出科学、可信的说明。
国际原子能机构技术工作组虽已三次赴日实地考察评估,但尚未就日排海方案的安全性给出结论,并且对日本提出诸多澄清要求和整改意见。在此情况下,日本仍执意推进核污水排海工程建设,这是极不负责任的行为。
太平洋不是日本的下水道,日本必须正视各方合理关切,在与周边国家等相关利益方和国际原子能机构充分协商后,制定合理的核污水处理方案。日本也要着眼长远,若只顾眼前,执意将核污水排放入海,不仅其自身,周边国家乃至全世界都将为之买单,其后果必将会危害数代人。
Fukushima water disposal by no means Japan’s own business
By John Lee
(ECNS) -- Japan has announced it will release treated wastewater from the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean this year.
Although Fukushima wastewater disposal affects global marine ecological environment protection and public health, Japan has turned a deaf ear to domestic and international opposition to dumping the contaminated water into the sea, treating the "global" matter as its own business.
The Fukushima accident in 2011 had sent large quantities of radiation into the atmosphere and the Pacific Ocean, causing irreversible damage to the surrounding environment, and hundreds of thousands of people were forced to evacuate the area. South Korea still maintains its import ban on Japanese seafood from areas affected by the Fukushima nuclear disaster.
On April 13, 2021, Japan announced it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea due to dwindling storage space, with the Japanese government and plant operator Tokyo Electric Power Company Holdings Inc. promoting the release plan over the past year.
The Japanese government argues that the water treated by an advanced liquid processing system, or ALPS, is safe and drinkable, which is undoubtedly fooling the public.
In fact, the treated wastewater still includes a variety of radioactive substances and can’t be recycled once discharged into the sea, which will pose a great threat to marine ecology and ultimately endanger human health in the long run.
Therefore, the discharge plan has been strongly opposed in Japan. According to a questionnaire conducted by The Asahi Shimbun, nearly 60 percent of mayors of 42 municipalities in Iwate, Miyagi and Fukushima prefectures oppose the discharge plan. The National Fisheries Cooperative Federation of Japan has also repeatedly stated its opposition in public.
The Japanese government believes that dumping Fukushima wastewater into the sea is the cheapest and most convenient solution, but neighboring countries and even the whole world will be at risk of nuclear pollution.
The Pacific Ocean doesn’t belong to Japan and the wastewater flow along oceanic currents will surely break boundaries and endanger public welfare and the interests of neighboring countries and even the international community.
The Korea Economic Daily reported that related research concluded that if contaminated water from Fukushima is released into the ocean, it would only take seven months for the contaminated water to reach the shores of Jeju Island, with the country's aquaculture and tourism suffering considerable losses.
According to the calculation of a German marine scientific research institute, radioactive materials will spread to most of the Pacific Ocean within half a year from the date of discharge, and the U.S. and Canada will be affected by nuclear pollution. People in the Pacific region also oppose the discharge plan.
As a participant of the United Nations Convention on the Law of the Sea, Japan has the obligation of protecting the marine environment.
However, it hasn’t offered a full and convincing explanation on issues like the legitimacy of the discharge plan, the reliability of data on the nuclear-contaminated water, the efficacy of the treatment system or the uncertainty of environmental impact.
Though the IAEA has yet to complete a comprehensive review after three investigations in Japan, the Japanese side has been pushing through the approval process for its discharge plan and even started building facilities for the discharge. It is rather irresponsible for Japan to act against public opinion at home and concerns abroad.
The Pacific Ocean is not a private Japanese sewer. The country must seriously heed the voices of the international community and make a reasonable plan for the Fukushima wastewater disposal after full consultation with stakeholders and international agencies.
If it only seeks instant interest and insists on discharging the contaminated water into the sea, not only itself, but also its neighboring countries and the entire world will pay for the decision and several generations will be forced to bear the consequence.
康复期怎样避免心肌损伤?这5点不能忽视→****** “新冠防治 有问有答” 邀请权威专家 对新冠防治过程中的热点问题 进行答疑解惑 马上看看 今天有哪些问题吧↓↓ 问:怎么判断自己是否患上了病毒性心肌炎?什么情况要去医院? 注意以下几种表现。 疑似出现病毒性心肌炎时,一般都会有胸痛、心悸、活动耐量减退的症状,比如说走走路、做做事情,就感觉到心悸、气喘,如果3周后症状还没有好转,需要及时就医。 医生通过心电图、心肌标志物、心脏彩超、心脏核磁共振等检查,会综合在一起来判定是否患上了病毒性心肌炎。 问:最近大家都在讨论病毒性心肌炎,听得我很焦虑,感染新冠后患上病毒性心肌炎的几率到底高不高? 发病率并不算太高。 首先,根据目前已有的临床病例,我们基本能够确定新冠病毒的确有可能会引发病毒性心肌炎。 病毒进入身体后,主要机理有2种,一种是病毒损伤了心肌,这其实只占比较小的一部分。而另一种情况是,人体感染病毒后,诱发了自身的免疫反应,产生对抗入侵病毒的抗体,但如果此时抗体出现“短路”,那么就会错误地攻击我们自身的心肌细胞,导致病毒性心肌炎的发生。在临床上,心肌炎属于危重疾病,猝死率很高,暴发性心肌炎死亡率达到20%~30%。 但不论是普通的心肌炎,或是由新冠病毒所导致的病毒性心肌炎,都属于相对罕见的疾病,发病率并不算高,大概每10万人每年会出现10~100例心肌炎患者。 实际上,绝大部分患者是在感染新冠病毒后,出现了心肌细胞受损,远远没有达到心肌炎的程度。 问:我“阳”了,康复期怎样避免心肌损伤? 做好这3点。 在抗原或核酸转阴后,不能一下子就“撒欢”了,想降低心肌炎及其他心脏并发症的风险,新冠感染后约3周需做好以下3点: 1.不要剧烈运动,不要过度劳累,尽量减缓工作节奏。 2.晚上不能熬夜,一定要早睡早起。 心脏是一个非常讲究昼夜节律的器官,它由交感神经、植物神经系统来支配整体运行。当你通宵达旦地熬夜后,哪怕睡足了8个小时,对心脏来讲,它的交感神经兴奋性也会增高,压力会增大,那么就可能导致恶性的心律失常。 3.充分补充营养。 充分补充维生素类、高蛋白类食物,还要注重摄入微量元素,比如钾、钠等电解质,对心脏都有好处。 问:我已经“阳康”了,多久后能锻炼? 4周后可以逐步恢复锻炼。 大部分轻症患者症状消退后2~3周内,不要进行高强度运动。4周后若身体没有不适,可循序渐进地锻炼,但一定要把握好度,不能一上来就恢复到原来的运动量,要慢慢来。 问:听说辅酶Q10对心脏好,要不要先吃上,避免心肌炎? 不需要。 辅酶Q10又称泛素酮,是一种天然存在于人体的物质,心脏、肝脏、肾脏和胰腺中的含量最高。 如果得了心肌炎,在医生的指导下服用可能有帮助,但对于预防心肌炎来说,辅酶Q10是没有用的。 目前,没有明确证据支持辅酶Q10可以预防心脏疾病。只要能够正常进食,并且做到均衡饮食,通常不会缺乏辅酶Q10。 (文图:赵筱尘 巫邓炎) [责编:天天中] 阅读剩余全文() |
