怎样保持房间空气清洁

现代社会中，人的一生平均有超过60%的时间是在室内度过的，这个比例在城市里高达80%－90%。因此，室内空气质量与人体健康的关系十分密切。

有关专家介绍说，家庭室内空气污染主要包括两大类：一类是气体污染物。如厨房煮饭炒菜产生的一氧化碳、氮氧化物及强致癌物；室内装饰材料、化妆品、新家具等散发出的有毒有害物质，主要有甲醛、苯、醚酯类及三氯乙烯、丙烯腈等挥发性有机物，以及氡气、“嘎玛”射线辐射等；还有人本身也是空气污染源之一，有关数据显示，每人每天呼出约500升二氧化碳气体，人的皮肤散发的乳酸等有机物则多达271种。据测定，居室内一支香烟的污染比马路上一辆汽车的污染对人体的危害还要大。

另一类是微生物污染物。如细菌、病毒、花粉和尘螨等。室内潮湿的地方，容易滋生真菌，造成微生物污染室内空气。真菌在大量繁殖的过程中，还会散发出令人讨厌的特殊臭气。这些生物污染可以引起房屋使用者的过敏性疾病及呼吸道疾病等健康损害。因此，可以说“家庭环保”的重点就是要消灭这些污染来源，这样不仅对家庭成员的健康提供了保证，同时也会减少对外部环境的污染。

下面向您介绍一些改善室内空气质量的方法：

首先，在您装修房屋的时候，要选择带有环境标志的绿色装饰材料。选择的大芯板应该是粘合剂不含苯二苯甲醛的；地板材料的甲醛含量应该达到挥发到稳定于每立方米0.12毫升以下；陶瓷瓷砖的放射性应该是A级大理石的放射性标准；涂料应该选水性涂料；塑钢等也应是正规企业生产的。您可以向中国建筑装饰协会等单位咨询这方面的详细情况，也可以请室内监测中心的人员来检测室内的空气质量。

其次，要充分发挥抽油烟机的功能。无论是炒菜还是烧水，只要打开灶具，就应把抽油烟机打开，同时关闭厨房门，把窗户打开，这样有利于空气流通，消除污染物。马桶冲水时放下盖子，平时不用时尽量不要打开。水箱中最好使用固体缓释消毒剂，并选用安全有效的空气消毒产品来净化空气。此外，在打扫卫生时，有条件的最好使用吸尘器，或者用拖把和湿抹布。如用扫帚，动作要轻，不要把灰尘扬起加重空气污染。鸡毛掸子容易造成“灰尘转移”，最好不用。地毯很容易吸附尘土和蟥虫、霉菌孢子等，又难以清洗，会使人产生一些不良反应，如皮肤瘙痒、打喷嚏等，尽量不使用地毯。

使用空调的家庭，最好能启用一台换气机。其中换热器效率较高者为佳，有的换热效率可达70%左右，所排出的冷风可以有效地将从室外抽入的热新风冷却，既可使室内空气保持新鲜，又可大幅度节约

能源，减少家庭的电费开支，是一种两全其美的选择。另一种有效的办法是使用空气净化器，常见的净化器类型有如下几种：(1)静电式室内空气净化器(主要用于可吸入颗粒物的净化)；(2)过滤式室内空气净化器(主要用于可吸入颗粒物和气态污染物的净化)；(3)复合式室内空气净化器(主要用于可吸入颗粒物和气态污染物的净化)；(4)净化性涂料(如纳米涂料用于气态污染物的净化)。

要保持居室空气新鲜洁净，最有效、最经济的办法就是经常通风换气。开窗通风要选择合适的时间，一般上午十点或下午三点，开窗通风半小时，就能使室内的空气进行交换。当然，如果外面空气污染很严重，就暂时不要开窗。如果有时间、有条件，最好经常到空气清新的自然中去呼吸新鲜空气。

第二篇：怎样保护环境

How to save environment? I think we should do the followings: First, it’s best to ride a bike to school, don’t take a bus or a taxi. Second, I will remember to turn off the lights when I leave the classroom. Third, in my free time, I will collect the empty bottles and waste paper for recycling. The fourth idea is turning off the shower when I ‘m not using it. Fifth, it is imporment to save water and money. Also, I won’t spend too much money on expensive things. Last, we had better not cut down the trees, we have to take care of the trees . I’ll try my best to save the energy, I hope I can do something for our country.

The environmental protection is the most major problem which in the modern life the humanity faces. Must solve this problem must start from foundation. First, must massively propagandize, enhances people's consciousness with understanding, strengthens the environmental protection consciousness. Next, must carry on waste recovery use, reduces to forest-tree's felling. Also must strengthen to white pollution processing, little uses the plastic product. Finally, must make improvement to clean aspect. Causes the city's appearance to be neater. For Earth's tomorrow, we must start from the now diligently, will want the well local constable to protect the environment. To this us proposes as follows suggests: Implementation trash classification packed in bags. Like this not only can reduce the environmental sanitation worker's work load, but also can even better basically arrive makes use of waste, to reduce the pollution, saves the resources.

The environmental protection is the most major problem which in the modern life the humanity faces. Must solve this problem must start from foundation.

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut

down and waste water is being poured continuously into rivers.Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.
