我们的水球
有人说,我们的地球应当叫水球.这是有一定道理的,因为我们生活的这个星球有水,而且71%的表面积被水占着.在宇航员看来,地球是一个蓝色的球,十分璀灿,太阳系家庭中独一无二.地球拥有的水量非常巨大,总量为13.86亿立方千米.其中,96.5%在海洋里；1.76%在冰川、冻土、雪盖中,是固体状态；1.7%在地下；余下的,分散在湖泊、江河、大气和生物体中.因此可以说,从天空到地下,从陆地到海洋,到处都是水的世界.
惊天动地的水循环 ,全世界的水是一个有联系的整体.海水在阳光的照射下,不断蒸发,水汽弥漫在海洋上空；一部分水汽被气流带到陆地上空,遇冷就凝结成细小的水滴,变成云,降落到地面就是雨或雪；雨雪水落地后,有的流到洼坑里,有的渗入地下,有的流入小沟,汇进江河,奔向海洋.无数小水滴就是这样一刻不停地在世界上旅游.水循环保证了人类淡水的供应.知道水的循环以后,你就能解释：云的故乡在哪里?为什么江河里日日夜夜总是川流不息?为什么千万年来那么多江河水流进海洋,而海洋不见满溢出来?
淡水在哪能里 地球上的水,尽管数量巨大,而能直接被人们生产和生活利用的,却少得可怜.首先,海水又咸又苦,不能饮用,不能浇地,也难以用于工业.其次,淡水只占总水量的2.6%左右,其中的绝大部分（占99%）,被冻结在远离人类的南北两级和冻土中,无法利用,只有不到1%的淡水,它们散布在湖泊里、江河中和地底下.与全世界总水体比较起来,淡水量真如九牛一毛.
Our water polo
Someone said, our earth should call water polo. This is a reason, because of our lives, and our planet is water surface area by water 71% takes. The astronauts opinion, the earth is a blue ball, very resplendent in the family, the solar system is unique. Earth has very great volume of water, total 13.86 billion cubic kilometers. Among them, 96.5% in the sea, The frozen earth, snow in glaciers, cover, is a solid state; 1.7% in underground, The remaining, scattered in the lakes, rivers, atmosphere and organisms. Therefore we can say that from the sky to the ground, from land to sea, the water is all over the world.
Earthshaking, the world's water circulation water is a contact of the whole. Seawater in sunshine, constantly evaporation, steamy over the sea, Part of water vapor was brought to land, air over they get cooler condenses into small droplets into clouds, fell to the ground is rain or snow, After landing, some rain water flow to the hollow pits, some infiltration underground, some into small groove, remit into rivers and rush to the ocean. Countless droplets that keeps momently ground in the world tour. Water cycle guarantee human freshwater supplies. Know the water cycle later, you can explain: cloud hometown in where? Why always flowing rivers days and nights? Why so many thousands of rivers flow into the sea, and Marine missing overflow?
Freshwater where can the water on the earth, although there are tremendous, and can directly by people living and production to use, but a little. First, seawater and salty again bitterness and not drinkable, cannot irrigate fields, it will be difficult for industrial. Secondly, freshwater accounts for only total water 2.6 or so, most of them (99%), frozen in the north and south of stay away from the humans two level and permafrost, cannot use, less than 1% of fresh water, they spread in lakes, rivers and underground. With the world total water comparison, freshwater really like a snip.
2、VOCS（挥发性有机物）
室内空气中的VOCS主要来源于各种建筑和装饰材料,如油漆、涂料、粘胶剂、室内装饰用品、空气消毒剂、杀虫剂等化工产品释放、燃料燃烧、烹饪、环境烟草烟雾,日用化学品等.VOCS对人的各种粘膜刺激作用中最常见的是对眼、鼻、咽喉部位的刺激,引起眼睛刺痛和干燥感,眨眼频率增加,并常伴有无其他症状的流泪,眼分泌物增多.使泪膜的稳定性降低,泪液中细胞含量发生变化如白蛋白浓度增加,出现鼻咽部干燥、刺痛、鼻血、鼻塞并可出现咳嗽、声音嘶哑和嗅觉改变等.咽部检查可见咽喉充血、炎症.皮肤多见干燥、瘙痒、刺痛、红斑等.VOCS污染严重时可致神经精神机能失调及痴呆.许多VOCS还可导致过敏性肺炎.

Indoor O3 mainly comes from copiers.the equipment and outdoor. O3 of strong oxidation force is harmful to human body health role. Crowd short-term O3 after exposure can appear sharply reduced lung function level. The smell of the threshold for 40 O3 muon g/m3, in 100 muon g/m3 below, is considered to be without effect dose concentration. 200 mu g/m3 can be susceptible persons of eye, nose and throat mucous membrane produces stimulation, When the concentration of 300 mu g/m3, nearly 30 percent of people who have mucosal excitement, A second largest 15% of the crowd expiratory flow down; Up to 400 mu g/m3, 50% of the crowd stimulates the production of symptoms, 25% of the crowd a second largest expiratory flow decline. O3 concentration in 2ppm m3 (4.28 mg /), shorter contact can appear respiratory symptoms of irritation, headache, cough, in this concentration by exposing 2 hours can have difficulty breathing, chest pain. Low concentration O3 long-term effects can restrain the body's immune function.
6、硫化氢（H2S）
室内H2S污染主要来源于下水道、生活垃圾、污物等,另外,人体呼出气、汗液、大小便等也可排出H2S.H2S是无色有臭鸡蛋味的气体,对中枢神经系统,上呼吸道系统有较强的刺激,易引起中毒.低浓度H2S中毒症状为头痛、头晕、恶心、呕吐；高浓度H2S中毒症状为昏迷、意识突然丧失、窒息死亡.
室内空气二次污染主要由使用空调调节系统引起.空调对人体健康的危害可分为三大类：急性传染病,过敏性疾病（肺炎和哮喘）和不良建筑综合症.空调环境下工作和生活的人容易出现疲乏、头疼、胸闷、恶心、嗜睡、易感冒等症状,即所谓的“空调综合症”.
6, hydrogen sulfide (H2S)
Indoor H2S pollution mainly come from the sewer, living garbage, dirt, etc, in addition, human breath, sweat and urine to wait to also can discharge H2S. H2S is colorless bad egg flavor of gas, the central nervous system, the upper respiratory system has the strong stimulation, easy cause poisoning. Low concentration H2S poisoning symptoms for headache, dizziness, nausea, vomiting, High concentrations of H2S poisoning symptoms for coma, consciousness suddenly loses, suffocation deaths.
Indoor air secondary pollution mainly by using air conditioning control system is caused. Air conditioning damage to human body health can be divided into three categories: acute infectious diseases, allergic diseases (pneumonia and asthma) and bad building syndrome. Air conditioning environment to live and work appears easily fatigue, headache, chest tightness, nausea, drowsiness, easy to catch a cold, the so-called "air conditioning syndrome".
