In April, "Blowing sand" is hazardous to health
The biggest hazard of aerosol particles are
April each year, in northern China usually spread over much of the dust, the vertical visibility is also very poor, even the dust covered roads and buildings, motor vehicles驰过will be raised a fan of the pungent黄尘eyes.
This weather on the weather as "blowing" and "dust", these two weather phenomena, along with even worse the "Sandstorm", collectively referred to as "blowing sand."
Many in April, "Blowing sand" because of climate and geography are two reasons, blowing sand weather great harm to human health.
Dust storms, as one of the most severe weather blowing sand, it is most harmful to human health directly.
When the dust storms, even the hidden interior, air and dust friction noise of the collision, but also make people feel sick mind; audio is too low, especially wind, can directly affect the body's nervous system, cause headaches, nausea, irritability .
Secondly, the fierce wind, sand and dust in the air often "vitamin" that is, negative oxygen ions was severely reduced, leading to some changes in the weather-sensitive changes in the human body, people are nervous tension and fatigue.
Sandstorm attack, low visibility, light dark, making the vision of people is restricted, people have a sense of depression and fear.
Jansa weather, although there was no cause for fear as dust storms, but the northern city are most likely to encounter a bad weather, when the weather comes blowing town, the local hospital in patients with facial features of the eye will be sharply increased.
Dust can cause eye pain, tears, if not removed, or hand-rubbing the eyes, can be caused by bacterial or viral eye disease.
So, when the weather there is blowing, the home should wear dust-proof glasses; such as sand and dust into the eyes, avoid rubbing his hands disorder that can be used wet towels to clean gently wipe, such as no effect, then go to the hospital ophthalmology.
Health hazards of dust, it is a static hazards.
Because whenever there is blowing sand weather, will result in the lower reaches of the sky and water pollution, dust, whether the whereabouts of, or turned into a sand storm, which would indeed harbor contains many particles, one of the biggest hazards on the human body are aerosol particles, which many greater than 0.001 microns in diameter are the solid, liquid particles, and some also contain a variety of micro-organisms and biological material, which formed a biological aerosols, on the human body is even greater harm.
For example, to carry the aerosol Mycobacterium tuberculosis may lead to the occurrence of tuberculosis, and with other bacteria such as Pneumococcus, Legionella bacteria, can trigger a variety of anaerobic bacteria from the pneumonia.
Therefore, when the dust when the weather, it is necessary to avoid going out as much as possible, close doors and windows well; there sand storm weather, it is important to pay attention to the detection and cleaning of drinking water to well water, pond water for drinking water in rural areas of the home, we must After the release of static can be used to clarify (alum water purification could also be considered), must not drink unboiled water.

危害最大的是气溶胶粒子
The biggest hazard of aerosol particles are
每年四月，我国北方地区的上空常常弥漫许多沙尘，垂直能见度也极差，沙尘甚至覆盖了道路和建筑物，汽车驰过，会扬起一股迷眼刺鼻的黄尘。
April each year, in northern China usually spread over much of the dust, the vertical visibility is also very poor, even the dust covered roads and buildings, motor vehicles驰过will be raised a fan of the pungent黄尘eyes.
这种天气气象上称为?扬沙?和?浮尘?，这两种天气现象，连同更为恶劣的?沙尘暴?，统称为?吹沙?。
This weather on the weather as "blowing" and "dust", these two weather phenomena, along with even worse the "Sandstorm", collectively referred to as "blowing sand."
四月多?吹沙?，是因为气候和地理两方面的原因，吹沙天气对人体健康的危害很大。
Many in April, "Blowing sand" because of climate and geography are two reasons, blowing sand weather great harm to human health.
沙尘暴，作为一种最严重的吹沙天气，它对人体身心健康的危害最为直接。
Dust storms, as one of the most severe weather blowing sand, it is most harmful to human health directly.
沙尘暴出现时，即便是躲在室内，空气及沙尘的冲撞摩擦噪音，也会使人们心里感到不适；特别是大风音频过低，能直接影响人体的神经系统，使人头痛、恶心、烦躁。
When the dust storms, even the hidden interior, air and dust friction noise of the collision, but also make people feel sick mind; audio is too low, especially wind, can directly affect the body's nervous system, cause headaches, nausea, irritability .
其次，猛烈的大风、沙尘常使空气中的?维生素?即负氧离子严重减少，导致一些对天气变化敏感的人体内发生变化，让人感到神经紧张和疲劳。
Secondly, the fierce wind, sand and dust in the air often "vitamin" that is, negative oxygen ions was severely reduced, leading to some changes in the weather-sensitive changes in the human body, people are nervous tension and fatigue.
沙尘暴袭击时，能见度较低，光线阴暗，使得人的视野受到限制，让人产生一种压抑和恐惧之感。
Sandstorm attack, low visibility, light dark, making the vision of people is restricted, people have a sense of depression and fear.
扬沙天气，虽然没有沙尘暴那样令人恐惧，却是北方城市最易遭遇的一种恶劣天气，每当扬沙天气降临城市，当地医院五官科的眼疾患者就会急剧增多。
Jansa weather, although there was no cause for fear as dust storms, but the northern city are most likely to encounter a bad weather, when the weather comes blowing town, the local hospital in patients with facial features of the eye will be sharply increased.
沙尘可直接引起眼睛疼痛、流泪，如不及时清除，或用手揉眼睛，均可引起细菌性或病毒性眼病。
Dust can cause eye pain, tears, if not removed, or hand-rubbing the eyes, can be caused by bacterial or viral eye disease.
所以，当有扬沙天气时，出门应戴防尘眼镜；如沙尘进入眼睛，切忌用手乱揉，可用干净的湿毛巾轻轻擦拭，如没有效果，则要去眼科医院就诊。
So, when the weather there is blowing, the home should wear dust-proof glasses; such as sand and dust into the eyes, avoid rubbing his hands disorder that can be used wet towels to clean gently wipe, such as no effect, then go to the hospital ophthalmology.
浮尘对健康的危害，则是一种静态的危害。
Health hazards of dust, it is a static hazards.
因 为每次出现吹沙天气，都会造成下游地区天空和水的污染，无论浮尘下落，还是演变成沙雨，里面都会含有大量的尘沙粒子，其中对人体危害最大的是气溶胶粒子， 它们多是直径大于0.001微米的固体、液体颗粒，有的还含有多种微生物和生物性物质，这就形成了生物气溶胶，对人体的危害就更大了。
Because whenever there is blowing sand weather, will result in the lower reaches of the sky and water pollution, dust, whether the whereabouts of, or turned into a sand storm, which would indeed harbor contains many particles, one of the biggest hazards on the human body are aerosol particles, which many greater than 0.001 microns in diameter are the solid, liquid particles, and some also contain a variety of micro-organisms and biological material, which formed a biological aerosols, on the human body is even greater harm.
例如，携带结核杆菌的气溶胶可能会导致肺结核的发生，而带有其它细菌如肺炎球菌、军团杆菌、各种厌氧菌者均可引发相应的肺炎。
For example, to carry the aerosol Mycobacterium tuberculosis may lead to the occurrence of tuberculosis, and with other bacteria such as Pneumococcus, Legionella bacteria, can trigger a variety of anaerobic bacteria from the pneumonia.
所以，当浮尘天气出现时，要尽可能地避免外出，关闭好门窗；出现沙雨天气时，必须注意对饮用水的检测和保洁，以井水、池塘水为饮用水的农村家庭，必须静放澄清后才可使用（也可以考虑明矾净水），绝对不可饮用生水。
Therefore, when the dust when the weather, it is necessary to avoid going out as much as possible, close doors and windows well; there sand storm weather, it is important to pay attention to the detection and cleaning of drinking water to well water, pond water for drinking water in rural areas of the home, we must After the release of static can be used to clarify (alum water purification could also be considered), must not drink unboiled water.
