<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">网上有<span style="color: black;">非常多</span><span style="color: black;">文案</span>和视频到处宣传甲醛的<span style="color: black;">害处</span>,以及<span style="color: black;">各样</span>致癌和白血病<span style="color: black;">危害</span>,有些<span style="color: black;">乃至</span>写的非常夸张。<span style="color: black;">那样</span>,甲醛到底有多可怕?<span style="color: black;">咱们</span>今天<span style="color: black;">一块</span>学习一下甲醛的<span style="color: black;">基本</span>知识和<span style="color: black;">关联</span><span style="color: black;">害处</span>,以及致癌的<span style="color: black;">危害</span>。<span style="color: black;">咱们</span>依然用问答的方式来阐述。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">1、</span>甲醛是什么?</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">甲醛,是一种无色,有强力刺激气味的易燃化学物质,<span style="color: black;">能够</span>工业生产,用途非常广泛。甲醛用来制作酚醛树脂,被用于<span style="color: black;">各样</span>建筑材料,<span style="color: black;">包含</span>胶合板、毛毯、隔热材料、木制<span style="color: black;">制品</span>、地板、装潢材料等等。甲醛还<span style="color: black;">能够</span>用作杀菌剂、消毒剂和防腐剂,<span style="color: black;">例如</span>在停尸房和医学实验室。有的<span style="color: black;">打扮</span>品、肥皂、洗发水等<span style="color: black;">亦</span>含有甲醛,甲醛<span style="color: black;">能够</span><span style="color: black;">做为</span>防腐剂添加到<span style="color: black;">食品</span>中。烹饪和吸烟<span style="color: black;">亦</span><span style="color: black;">能够</span>产生甲醛,还有汽车尾气。甲醛<span style="color: black;">亦</span>存在于自然环境,土壤的植物腐烂就<span style="color: black;">能够</span>产生。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">最重要的是,人体本身就会制造少量的甲醛,<span style="color: black;">做为</span>正常代谢的一部分。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">甲醛易溶于水,<span style="color: black;">针对</span>眼、鼻、皮肤有刺激<span style="color: black;">功效</span>,体积百分比40%的甲醛水溶液又<span style="color: black;">叫作</span>为福尔马林。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">我对甲醛最大的印象是上大学时,在解剖课上各小组<span style="color: black;">一块</span>解剖尸体,尸体是浸泡在福尔马林中的,挥发的气体含有<span style="color: black;">海量</span>甲醛,极其刺鼻,戴着护具都扛不住,操作一会眼睛就被刺激的直流眼泪,非常难受。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">2、</span>人类是怎么接触甲醛的?</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">重点</span>是吸入空气中的甲醛气体或蒸汽,<span style="color: black;">或</span>是<span style="color: black;">经过</span>皮肤吸收含有甲醛的液体,<span style="color: black;">或</span><span style="color: black;">经过</span><span style="color: black;">摄食</span>含有甲醛的<span style="color: black;">食品</span>和液体。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">重点</span>以吸入甲醛为主,<strong style="color: blue;">汽车尾气</strong>是室外空气中甲醛的<span style="color: black;">重点</span><span style="color: black;">源自</span>。含有<strong style="color: blue;">甲醛树脂的压制木材<span style="color: black;">制品</span></strong><span style="color: black;">一般</span>是家庭中甲醛的<span style="color: black;">源自</span>,<span style="color: black;">一般</span>会缓慢释放甲醛,这<span style="color: black;">已然</span>让甲醛<span style="color: black;">作为</span><span style="color: black;">平常</span>的室内空气污染<span style="color: black;">源自</span>之一。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这些让<span style="color: black;">咱们</span><span style="color: black;">每一个</span>人几乎不可能避开甲醛。 人体存在的酶<span style="color: black;">能够</span>把甲醛分解为甲酸盐,<span style="color: black;">而后</span>进一步分解为二氧化碳,大<span style="color: black;">都数</span>吸入的甲醛<span style="color: black;">能够</span>被口腔、鼻、喉咙和<span style="color: black;">呼气</span>道的细胞分解,进入血液的很少。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">除了屋子里的木制品和尾气<span style="color: black;">作为</span>甲醛<span style="color: black;">源自</span>,普通人接触甲醛还有吸烟和二手烟,以及开的汽车,因为汽车的电气系统、门板和缸体等,甲醛是其中的关键材料。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">重视</span>,生产甲醛或<span style="color: black;">关联</span><span style="color: black;">制品</span>的工人、实验室技术人员、卫生保健人员和太平间人员,接触的甲醛<span style="color: black;">一般</span>会更高的浓度水平,这些职业更危险。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">3、</span>甲醛的<span style="color: black;">通常</span><span style="color: black;">害处</span>是什么?</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">接触甲醛后,<span style="color: black;">能够</span><span style="color: black;">显现</span>眼睛刺痛,皮肤刺激、<span style="color: black;">呼气</span>道黏膜刺激、气喘以及<span style="color: black;">呼气</span>困难、中枢神经系统<span style="color: black;">损害</span>(<span style="color: black;">长时间</span>暴露于甲醛<span style="color: black;">能够</span><span style="color: black;">显现</span>倦怠、头痛、<span style="color: black;">睡觉</span><span style="color: black;">阻碍</span>、易怒、灵敏性减低、记忆力下降、平衡感受损)</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">4、</span><span style="color: black;">那些</span>癌症和严重<span style="color: black;">疾患</span>与接触甲醛<span style="color: black;">关联</span>?</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">甲醛<span style="color: black;">已然</span>被世界卫生组织确定为致癌和致畸的物质。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">医学上<span style="color: black;">发掘</span>,接触高浓度甲醛的工人,<span style="color: black;">例如</span>防腐工,甲醛会<span style="color: black;">引起</span>白血病和罕见的癌症,<span style="color: black;">包含</span>副鼻窦癌、鼻腔癌和鼻咽癌等。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">5、</span>甲醛的致癌<span style="color: black;">功效</span>到底有多强?</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">WIKI记录的甲醛<span style="color: black;">引起</span>劳工<span style="color: black;">病患</span>鼻咽癌的死亡比为2.1,暴露于高峰值浓度甲醛(≥4.0ppm)的相对危险性为1.83,整体上看并不算高。(<span style="color: black;">例如</span>重度吸烟<span style="color: black;">能够</span>让肺癌的<span style="color: black;">出现</span>率<span style="color: black;">增多</span>20-30倍以上,槟榔<span style="color: black;">长时间</span>嚼<span style="color: black;">乃至</span><span style="color: black;">能够</span>几百倍,相比这一下<span style="color: black;">害处</span>轻的多)</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">来自NCI(美国国家癌症<span style="color: black;">科研</span>所)的引用,Hauptmann<span style="color: black;">科研</span>了25619名工厂工作的劳工,</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">从1966年至1994年的时间段,<span style="color: black;">发掘</span>暴露于甲醛高平均浓度的劳工,比低平均浓度甲醛,<span style="color: black;">身患</span>髓性白血病RR值达到2.46,<span style="color: black;">亦</span><span style="color: black;">便是</span>接近2.5倍。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">重视</span>,这些<span style="color: black;">科研</span>都不<span style="color: black;">包含</span>普通人,而是从事暴露于甲醛工作的劳工,<span style="color: black;">危害</span>相对要高的多,其中低平均浓度甲醛的劳工患白血病的比例<span style="color: black;">亦</span>不高,<span style="color: black;">因此呢</span>,可以认为甲醛<span style="color: black;">引起</span>普通人致癌的可能性其实非常低,<span style="color: black;">不消</span>过于担心。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">6、</span>甲醛更严重的<span style="color: black;">害处</span>是什么?</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">是对孕妇<span style="color: black;">害处</span>更严重,<span style="color: black;">太多</span>接触甲醛可<span style="color: black;">引起</span>怀孕<span style="color: black;">时期</span>胎儿停止生长<span style="color: black;">生长</span>、心脑<span style="color: black;">生长</span>不全、严重<span style="color: black;">引起</span>畸形和流产等严重后果。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">总结:</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">甲醛几乎无处不在,不可避免的会有接触。<span style="color: black;">长期</span>接触甲醛会<span style="color: black;">引起</span><span style="color: black;">各样</span><span style="color: black;">损害</span>,<span style="color: black;">乃至</span>癌症和白血病发病率<span style="color: black;">上升</span>。</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">但请不要害怕,不要谈癌色变。普通人接触的甲醛水平要远远<span style="color: black;">小于</span>从事甲醛<span style="color: black;">关联</span>工作人员,而甲醛<span style="color: black;">关联</span>工作人员,即使接触的是高浓度,某些癌症和白血病<span style="color: black;">危害</span>,相比低浓度的工作人员<span style="color: black;">亦</span>就<span style="color: black;">增多</span>不到3倍。普通人的<span style="color: black;">危害</span>要低得<span style="color: black;">更加多</span>,但要<span style="color: black;">尽可能</span>要避免<span style="color: black;">长期</span>暴露在高浓度环境中。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">因此</span>,甲醛的<span style="color: black;">害处</span><span style="color: black;">无</span><span style="color: black;">大众</span>想象的<span style="color: black;">那样</span>可怕,<span style="color: black;">然则</span></span><strong style="color: blue;"><span style="color: black;">孕妇确实<span style="color: black;">必须</span>更注意</span></strong><span style="color: black;">。普通人请别吸烟,<span style="color: black;">尽可能</span>不喝酒,规律运动,<span style="color: black;">重视</span><span style="color: black;">膳食</span>和饮水健康,患癌和大病的<span style="color: black;">危害</span>要小得多。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">担心家里的甲醛问题,家里就要<span style="color: black;">尽可能</span>多开窗通风,多出去走动,尤其是夏天,<span style="color: black;">由于</span>甲醛释放得更快。</span></p>
