Ozone poison gas pollution caused by high temperature
Not only is it hot enough to explode, but the air is poisonous!
Health authorities in the new state yesterday issued an emergency air quality warning, causing toxic ozone due to sultry weather, non-circulation of air and pollutants such as car exhaust reacting with oxygen in the air under hot weather conditions.
Ozone, as a strong oxidant, stimulates the human respiratory system and nervous system. If the ozone concentration near the ground is too high, after a large amount of inhalation of the human body, will lead to sore throat, chest stuffy cough, strong, will also cause bronchitis, emphysema;
Ozone can stimulate the nervous system, resulting in dizziness and headache, vision loss, memory loss;
Studies show that for every 100 micrograms of ozone in the air, respiratory function is reduced by 3 percent.
If pregnant women are exposed to ozone during pregnancy, the baby may be born with congenital palpebral fissure.
Other photochemical pollutants associated with ozone pollution also cause great harm to human body. Besides respiratory system heart-brain system diseases it is also carcinogenic.
The air quality in Sydney is not very good these two days. Specifically remind respiratory disease patients, such as asthma patients should pay more attention to avoid going out.
It's abnormal heat, it's poison gas!
The UV index has exploded.
The worst part of Sydney today is not the heat or poison gas.
It's the UV index that's been popped up!
According to data from Apple's weather app, Sydney's outdoor UV index is as high as 9 today!
Editor again on weatherzone official website looked down, the results are even more frightening.
According to weatherzone, Sydney's UV index has soared to 14!
This Friday is as high as 16!
(the gap between the two PS: is relatively large, and the editor is not sure which side of the data is more reliable.) if you want to verify the data, please go to this address: http://www.weatherzone.com.au/uv-index/nsw/sydney/sydney)
According to weatherzone's weather forecast, there are daily UV alerts from today until Sunday.
Oh, my God!
It's not easy to live in Sydney.
Basically, you don't have to go out.
Did you take care of the sun when you went out today?
What is the UV index?
The ultraviolet index (Ultra-violet Index) refers to the international standard for the intensity of ultraviolet (UV) radiation from the sun at a certain point on a certain day. This series is mainly used in daily forecast and is aimed at the general public.
The Public Health Organization recommends that people take steps to protect themselves when the UV index is greater than or equal to level 3, for example, by applying sunscreen and wearing a hat on the skin.
So, UV index > = 9, what is the concept?
Let's take a look at the chart below and we'll be very clear.
Here's a screenshot from Wikipedia.
(can't see clearly, please cross the phone and click on the larger picture.)
When the UV index is between 8 and 10, there is a high risk of exposure to sunlight and rapid burns of the exposed skin.
When the UV index is higher than 11, exposure to sunlight is extremely dangerous!
The UV index level is unlimited, and the higher the value, the greater the risk of skin exposure to ultraviolet light.
According to records, the world's highest UV index record is 20!
What harm does ultraviolet ray have to human body?
Ultraviolet light is an electromagnetic wave with a wavelength less than visible light. Most of the ultraviolet light on the earth's surface comes from the sun. Ultraviolet light is a kind of harmful light, absorbed by the skin. Will hurt DNA~~ () $^ & * (~! @ $^ & *) (# ¥. & * &.% > (omit 5000 words here)
If you don't expect to see too much of it, the editor simply and rudely summarizes the harm of ultraviolet light in two words:
Cancer!
According to the Australian Cancer Society (cancer council), skin cancer accounts for 80% of all cancers examined in Australia every year, that is, 80% of Australian cancer patients are skin cancer patients.
According to the survey, 95% of skin cancer is caused by direct sunlight, precisely because of ultraviolet radiation!
How to prevent ultraviolet rays?
The Australian Cancer Council is a thoughtful guide to how to protect your skin in the sun. Almost every native Australian knows it from birth. Let's get to know and learn about sunscreen.
1. Wear a shirt
Covering the skin as much as possible, Australian organizations offer very high UV protection sunscreens that can be purchased in most department stores or retail stores.
2. Apply sunscreen
Use SPF30 sunscreen or higher, SPF30 can filter out more than 96% of UV radiation, SPF50 filter 98%.
When using sunscreen, remember to apply sunscreen to your skin 20 minutes before you go out and apply sunscreen again after two hours.
3. Wear a hat.
It is best to wear a broad hat so that the face can be protected in all directions. A baseball cap protects your eyes from the sun, but does not protect your neck, ears and face.
4. Looking for shade
This is the cheapest and simplest form of sun protection that can be sought, such as sitting under the shade of a tree, staying under the balcony, or using an umbrella outside.
5. Wear sunglasses.
I believe we all have a period of time in the sun, the eyes ache, UV is the culprit. Remember to wear sunglasses around your eyes so that your eyes are best protected. Check the label before buying to make sure the glasses are UV-proof.
In other places, sunglasses may be a pressing tool; in Australia, sunglasses are a must-have tool for survival!
When I think about it, I feel sorrowful.
The conclusion of the editor summarizes the above various methods, that is, two words!
Sunscreen!
Sunscreen!
Sunscreen!
The important thing, editor must say three times!
Living in Australia, summer without sunscreen is basically chronic suicide!
For the past two days, everyone try to stay indoors and stop playing around.
