Indoor air pollution kills 4 million 300 thousand people worldwide every year-masa-c

Indoor air pollution each year killed 4 million 300 thousand people worldwide experts interviewed: Sanitary Engineering Branch Director and vice president of the International Association of Dai eco economic Zizhu and Secretary General Li Junyang China academician of Academy of Engineering Hou Lian "HuangDiNeiJing" mentioned in the Chinese Preventive Medicine Association, "the people in the air of heaven and earth born". Here that the "gas" is the air. Indeed, people can not eat for 7 days, 2 days without water, but left the air in 5 minutes. The air is of great significance to people, and the demand for air is also very strong, each day to eat 1.5 kilograms of food, drink 2 kg of water, but need 15 kilograms of air breathing. We can choose food and water now, but it is difficult to choose the air, and we human respiratory system immunity than gastrointestinal sucked a lot worse, since it is very difficult to spit out. So, the air quality is essential to human health. Indoor air pollution is 2~5 times than outdoor unfortunately, poor air quality has become a global problem. In addition to this haze known as "killer", indoor air pollution, but can not be underestimated. The Chinese Preventive Medicine Association of Sanitary Engineering Society chairman Dai Zizhu said that the rate was even higher than the outdoor air pollution of indoor air pollution to death. The WHO’s data show that indoor air pollution each year caused 4 million 300 thousand deaths worldwide, outdoor air pollution caused 3 million 700 thousand deaths. Health authorities in Europe and the United States also pointed out that the indoor air pollution severity is 2~5 times outdoors, there are more than 1 million people died of chronic lung disease blocked every year, most from indoor air pollution. Vice president of the international eco economic association and the Secretary General Li Junyang in the "China city public environmental air and health effects during the 13th Five-Year issue" the seminar pointed out that the modern 80%~90% of the time is spent indoors, so indoor air quality on human health and life, the effect is more obvious. Hou Lian Chinese academician pointed out that at present the overall atmospheric quality is improving, although there is a long way to go, but the effect is obvious. However, indoor pollution control, pollution control or public environment, is also a long way to go. The main reason is the pollution characteristics is not clear, emission factors and other basic data accumulated too little research on risk assessment on human health is too little. Coupled with the market of interior decoration materials quality uneven, purifier market is still not standardized and other factors, will lead to poor indoor air pollution control. The pollution source is wide, affecting a wide range of indoor air pollutants that wish to wear self, has the following characteristics: first, the large range of influence. Everyone in the room, which is different from mine and other specific environment, indoor pollution affected a large number of people. The problem of indoor air quality impact on the more vulnerable groups, especially in pregnant women, children, the elderly and people suffering from respiratory diseases. But this kind of crowd often activities, such as schools, hospitals and public places such as subway, crowded, cross contamination is very serious, serious shortage of fresh air volume, more heavy their health threats. Secondly, the indoor pollution effect for a long time. People in the indoor living beyond the obvious time outdoors, especially white-collar work, to the company from morning to night to eat and sleep, a few.

室内空气污染每年导致全球430万人死亡受访专家:中华预防医学会卫生工程分会主任委员 戴自祝国际生态经济协会副会长兼秘书长 李军洋中国工程院院士 侯立安《黄帝内经》中提到,“人以天地之气生”。这里说的“气”就是空气。的确,人可以7天不吃饭,2天不喝水,但是离开空气5分钟就不行了。空气对人意义重大,而且人们对空气的需求也很旺盛,每个人每天吃进去1.5公斤的食物,喝2公斤的水,但是需要呼吸15公斤的空气。我们现在可以挑选食物和水,但是很难挑选空气,而且我们人类呼吸系统的免疫力比胃肠道差很多,吸进去以后很难再吐出来。所以,空气质量对人体健康来说至关重要。室内空气污染是室外的2~5倍遗憾的是,空气质量差早已成为全球性问题。除了雾霾这个众人皆知的“杀手”外,室内空气污染更不容小觑。中华预防医学会卫生工程分会主任委员戴自祝表示,室内空气污染致死率甚至高于室外空气污染。世界卫生组织的数据显示,室内空气污染每年导致全球430万人死亡,室外空气污染则导致370万人死亡。欧洲和美国的卫生当局也指出,室内空气污染严重程度是室外的2~5倍,每年有超过100万人死于慢性堵塞性肺病,大部分死于室内空气污染。国际生态经济协会副会长兼秘书长李军洋在“十三五时期我国城市公众环境空气与健康影响课题”研讨会上指出,现代人80%~90%的时间是在室内度过,因此,室内空气的好坏对人体健康和生活、工作的影响更为明显。中国工程院院士侯立安指出,目前大气环境质量总体是在改善,虽然还需要很长的路要走,但成效还是明显的。然而室内的污染控制,或者公众环境的污染控制,还任重道远。主要原因是污染特征不清晰,排放因子等基础数据积累得太少,对人体健康的风险评估研究太少。再加上市场上室内装修材料质量参差不齐、净化器市场还不规范等因素,都导致室内空气污染控制不佳。污染来源广,影响范围大戴自祝认为,室内空气污染物有如下特点:首先,影响的范围大。每个人都要在室内生活,这不同于矿井等特定环境,室内污染波及的人群数量很大。室内空气质量问题对弱势群体影响更大,尤其是孕妇、儿童、老人以及患呼吸系统疾病的人。而这类人群经常活动的场所,如中小学校、医院和地铁等公众场所,人员密集,交叉污染很严重,新风量严重不足等,更加重了他们健康的威胁。其次,室内污染作用时间长。人们在室内生活的时间明显超出室外,特别是白领,从早上到公司工作,再到晚上吃饭、睡觉,几乎全部在室内活动。再次,室内污染物种类多。例如室外空气中的PM2.5含量偏高,就会影响到室内空气。室外PM2.5的浓度达到300的话,室内也会在210左右。甲醛、苯、氨、放射性氡等有害物质超标,也会使室内空气变糟。最后,人的活动也会带来污染物,如吸烟、人体呼吸散发的污染物,这些对小孩的影响更多一些。戴自祝表示,家用的化学品有7万种,其中有部分是含有致癌物质的。家用电器有一些粉尘,现在大量的建筑装修、家具以及空调等散发出甲醛和异味,都会引起一系列的问题。一屋不净,何以净天下戴自祝强调,“一屋不净,何以净天下”。“天下”的问题很大,但首先需要把室内的问题解决,室内的空气质量有所提升,健康才会有保证,幸福感才会增加。防止室内空气污染不仅要抵御来自内部的多种污染物,还要抵抗来自室外的“入侵者”。想要打造健康住宅,首先应控制室内的污染源,能消除来源更好,但通常情况下,这是很难做到的。因此,戴自祝认为,限制污染源很重要,比如少用杀虫剂、经常清扫卫生间、尽量使用环保家具等。第二,需要减少暴露机会,加强通风换气,让空气得到净化。这是改善室内空气质量的关键,室外的新鲜空气稀释室内的空气污染物,使得浓度降低。但有时室外的空气污染比较严重,应该避免直接通风,需要对室外的空气先进行净化,即选用新风净化系统。第三,室内禁止吸烟是很好的措施,目前北京已经推广开来并实施得不错,其他城市也可以逐步实行。烟民在自己家中也尽量少吸烟,即使想吸烟也最好在通风好的地方吸。最后,国家应该大力发展绿色建筑和智能建筑。绿色建筑对环境来说是种保护,它主要是指为人们提供一些健康、舒适、安全的居住工作活动空间。还需要高效地利用能源和资源,节能、节水和节材,最低限度地影响环境。此外,李军洋特别指出,全国各地开展健康效果评估和空气污染控制时,应当“因地制宜”。由于我国不同城市空气污染水平、污染物组成、人口构成存在较大的差异,空气污染引发的健康问题效应也必然存在明显不同。充分综合国内外现有研究成果,基于国内不同城市污染水平、人口分布等具体情况,展开室内污染物的评估和控制,是加快推进我国室内污染治理的有效途径之一。相关的主题文章:
