The International Day of ozone protection is coming, but there are people who don't know

The ozone layer is like a "protective clothing" of the Earth, which blocks a large number of harmful ultraviolet rays from reaching the earth. If this "dress" breaks a big hole, it must be the person who wears clothes. Today is the 20th International Ozone Layer Protection Day, the reporter from the Environmental protection Department learned that, in fact, we less open a passing, buy refrigerator air-conditioning and other household appliances when the attention to the ingredients, repair the refrigerator when the choice of regular repair shop, will reduce human skin cancer, cataract opportunities.

Reporters visit the majority of the public do not know "world ozone Layer Protection Day"

"The ozone layer also has protection day?" What is the ozone layer? "Yesterday morning, the reporter randomly interviewed some people in the street to find that most of the people shook their heads to say they do not know, and even do not know what the ozone layer is."

City Environmental Protection Department head told reporters, in the ground 10 km-50 kilometers of the atmosphere of the stratosphere, concentrated in the atmosphere of about 90% of ozone. Of these, the ozone concentration is the highest in the atmosphere 15 km-25 km from the ground, which is the ozone layer we are trying to protect. "The ozone layer is like a ' protective clothing ' for humans and the earth that protects the planet from the effects of ultraviolet radiation," he said. ”

According to previous studies, the ozone layer is now 400 million years old, has been safe. Since 1974, it has been found that the ozone layer has been destroyed, and by the year 2006, the maximum size of the "ozone hole" found over the Antarctic continent has been as large as that of Africa as a whole. In addition, in the Arctic and some middle latitudes, there are also varying degrees of ozone depletion phenomenon, including the Qinghai-Tibet Plateau.

It is reported that our country signed the Vienna Convention for the Protection of the Ozone layer in 1989, and in 1991 and 2003 successively acceded to the London Amendment and the Copenhagen Amendment of the Montreal Protocol on Substances that Deplete the Ozone Layer. This means that, as a State party, our country must progressively "eliminate" the ozone layer killer in accordance with international conventions.

Market research Yang City has long been "forbidden fluoride", fluorine-free household appliances everywhere

"The main culprits for destroying the ozone layer are HCFCs that are emitted when people use air-conditioning and refrigerators," he said. "Environmental experts, such as a HCFCs (Freon) molecule decomposition of chlorine atoms, can be repeated attacks on the ozone molecule indefinitely, destruction time can be up to 100 years, a total of" murder "100,000 ozone molecules. Even if we destroy all these killers now, they will continue to destroy the ozone layer for decades.

What is the status of the primary "killer" material about the ozone layer in our city? Yesterday afternoon, the reporter visited more than a few electrical stores in Yang City found that from 2007 onwards, Yang City market has long been "fluoride", now, eyeful "fluorine-free" home appliances. "With the national release of Freon refrigerant provisions, usually with Freon refrigerant products as of 2010 all not allowed to sell." "A staff introduction.

"The so-called fluorine-free air-conditioning is not no freon, Freon is just a large category of refrigerant, where special reference to R12 or R22, general car air-conditioning use R12, home air-conditioning use R22." "Environmental experts also introduced the daily life of the minimum temperature of air-conditioning set at 26 ℃ or more, can effectively reduce the discharge of freon."

Expert reminder

Air conditioners, pesticides, etc. may contain fluoride

Expert reminder

Protecting the ozone layer is actually protecting ourselves. How can we reduce the depletion of the ozone layer in our daily life?

It is reported that many of the products related to our lives may contain fluorine, such as foam (a large number of existing in the sofa, a one-time foaming meal box, car interior foam, heat preservation spraying), fire extinguishing agent, aerosol (mousse, pesticides, aerosol sprays), cleaning agents, expanded tobacco and so on. The Environmental Protection Department also suggested that in the life of choosing the following consumer goods to pay attention to the ingredient description: refrigerators, air-conditioning, mousse, air freshener, fire extinguishing agent, spray insecticide, bleach and so on.

"For example, when you buy air-conditioning refrigerators, be sure to look at the above environmental protection signs; dispose of waste appliances, do not forget to remove the refrigerant, car air-conditioning is not refrigeration, to have a refrigerant recovery equipment repair points." "Environmental experts introduced. "Check the surrounding amenities, including detergents, mousse, sponge pads, altered fluids, ink, etc. to see if there is a ' killer ' substance." Never use pesticides containing methyl bromide in crop production. ”

In addition, the greenhouse effect brought about by the warming of the Earth, will also accelerate the decomposition of ozone, so we rarely open a car, hot days when the air-conditioning to increase 1℃ ... These small habits can effectively reduce energy consumption. Reporter Shishuven
