Main function: absorb short-wave ultraviolet rays. If the ozone layer is depleted a lot, its ability to absorb ultraviolet radiation will be greatly weakened, which will bring harm to human health and the ecological environment.

As human activities intensify, there are serious holes in the ozone layer on the surface of the earth. Protecting the ozone layer is to protect the blue sky and protect life on the earth. Therefore, the United Nations General Assembly decided that September 16 of each year is the International Ozone Layer Protection Day.

Speaking of ozone

I can’t help but think of the chemistry knowledge in high school

Ozone is a "fat man who wants to get thinner"

It slowly gave its oxygen atom oxygen to oxygen

But later

humans sent a "black heart weight loss coach" chlorine

let ozone start to "lose weight" recklessly

Cl + O3 →ClO + O2ClO + O →Cl + O2

balance is tilted towards oxygen.

Ozone disappears just a little bit.

So what is the ozone layer?

What is ozone pollution ?

What does it have to do with them? How to protect the ozone layer

?

What is the ozone layer?

ozone layer refers to the relatively high part of the ozone concentration in stratosphere in the atmosphere. Most of the ozone layers in nature are distributed at altitudes 10-50 kilometers above the ground.

main function : absorb short-wave ultraviolet rays. If the ozone layer is depleted a lot, its ability to absorb ultraviolet radiation will be greatly weakened, which will bring harm to human health and the ecological environment.

What is ozone pollution?

Ozone pollution and PM2.5 are the main reasons affecting the air quality in urban environment, and its primary pollutant ozone is the "culprit".

main source : ozone pollution, like lead pollution , sulfide, etc., it also originates from human activities. Motor vehicles, fuel, petrochemicals, etc. are important sources of ozone pollution.

is Buddha in the sky and is a demon in the earth

Everyone must be confused.

Ozone replaces PM2.5 and becomes the primary pollutant

What does this have to do with protecting the ozone layer?

The so-called "good" ozone refers to the ozone in the stratosphere of the atmosphere, 12 kilometers to 35 kilometers away from the ground, like a protective umbrella, blocking ultraviolet rays from the earth, and playing a good protective role for the earth's organisms.

and "bad" ozone is what we call low-altitude ozone , which roughly appears in the atmosphere about 2.5 kilometers from the surface in midsummer. Once these "bad" ozone exceed the standard, it will become an invisible killer and endanger human health.

OZONE LAYER

As a resident of the earth,

What can we do to protect the ozone layer?

consumer who cares about the ozone layer: buy products with the "care for the ozone layer" or "chlorofluorin-free" logo (such as aerosol cans, refrigerators, fire extinguishers, etc.).

. Be the head of the family who cares about the ozone layer : Reasonably deal with used refrigerators and electrical appliances. Before disposing of electrical appliances, the chlorofluorocarbon and chlorofluorocarbons and refrigerant should be removed (ask the town’s public service department or home appliance company about the refrigerant reuse plan for electrical appliances). According to the recommendations of the fire department, purchase a fire extinguisher without halon (such as dry powder fire extinguisher).

. Be an office employee who cares about the ozone layer : Help your company identify existing equipment (such as water cooler , air conditioners, detergents, fire extinguishers) and purchased supplies (such as aerosols, sponge mattresses/mattresses, modification fluids) and materials that use ozone depletion materials, and develop a plan to replace them with cost-effective replacements. Be the pioneer in environmental protection in your office.

. Be an teacher who cares about the ozone layer : Tell your students about the importance of protecting the environment, especially protecting the ozone layer. Let students know the destructive effects of ozone-depleting substances on the atmosphere and human health, as well as actions taken at home and abroad to address this problem. Students are encouraged to popularize this knowledge to their families.

. Be an citizen who cares about the ozone layer : Learn to understand the impact of ozone layer depletion on humans, animals and the environment, and understand how to participate in the work of protecting the ozone layer at an individual level.

Sichuan environmental protection calls for everyone

There is only one

Everyone should make a contribution to it

protect the ozone layer

Protect ourselves
