Since the '80s (you see it right, the '80s there's haze) and almost every autumn, the northern part of china is experiencing haze weather, which is mainly a combination of climate and pollution. Because of high temperatures during the summer, autumn and night shifts, and resulting in steady weather conditions, these weather conditions are not conducive to the release of pollutants from the air stream. At the end of the autumn, the temperature is low and the humidity is high, making it easier to form mist. Not only that, in recent years, large cities have been highly susceptible to haze due to the high accumulation of pollutants. It was questioned why there were not many motor vehicles in beijing during the holiday period and why the fog was so heavy, but in practice the short-term traffic changes did not have a significant impact on the air。
You don't say the fog is too short-term? Maybe you still don't know how serious it is! In the past, the main component of atmospheric pollution, according to the chinese engineering institute, was dust deposition, while the current haze is actually a chemical substance such as carbon monoxide and nitrogen oxides. The haze is mixed with many harmful substances, with which humans inhale the haze, and hundreds of atmospheric particles can enter and be adhesived directly into the body's upper and lower respiratory and lung leaves, and most of them may be inhaled by humans. Furthermore, mist weather reduces the near-earth ultraviolet light, tends to increase the activity of bacteria in the air, and fine particles “carrying” bacteria, viruses to the depths of the respiratory system, causing infection. It also includes irreversible damage to the nervous system, the cardiovascular system, the respiratory system and the endocrine system, but the most immediate and terrible of these is carcinogenicity
The planet is so big that if the outdoor environment is not spared, is the indoor environment so good? For now, instead of saying “psychological consolation” such as “closing doors and windows and opening a purification machine”, the source of indoor pollution may not be the same as the “dark” outdoors. Looking around your office, if we can see countless microworlds: wormed parasites and bacteria on the carpet, the photocopying machine that was taken off its own feet and powdered with dust and fungus in the air, how many threats are you facing
In fact, we should ask these indoor “shadows”: contact with bacteria and light dust is inevitable, but human resistance is born, and dust attached to the respiratory tract can be discharged with the venom; trace bacteria inhaled into the human body can be swallowed up in a moment by white cells... None of these are of concern to you. But have you ever thought that there is no material body that can fight? Of course, look at the laser printer you're working next to. The powder that shakes is the real killer of cancer
This is a definition from an encyclopaedia: ink powder (also known as carbon powder) is not primarily carbon, but consists mostly of resin and carbon black, electric chargers, magnets, etc. Ink powder melts into paper fibres at high temperatures, and resins are oxidized into gas with an irritant scent, which is known as `ozone'. The only advantage of this gas is to protect the earth and reduce the hazards of solar radiation. Nothing good for the human body itself can irritate the mucous membranes of the human body, easily increasing the incidence of asthma or an allergic nose, even dizziness, vomiting, etc。
Is this a more chemical-like jar
We even know that real selenium drums are expensive! So many people are speculating, either poking their own holes or buying a pseudo-silver accelerator in a certain county. It's not impossible, but would you like to let these imprudent processes hurt you and your friends and family? We even have a common sense that powder is bound to produce carbon powder, and how small is it? I must warn you, don't let him touch your skin while he's still powdered
There must be a reason for "expensive" and no big brand will lie to you about such a hot market competition! The main component of carbon powder is resin, while the main component of carbon powder is carbon black (what harms it to you or search for it). The positive amphibian drums are more of those that use specialized and conscientious substances, such as waxes, while the replacement drums contain substances such as “pyrocyclic aromatic series and dimethyl nitrate”, which are respectively carcinogenic substances nos. 3 and 4 issued by state authorities。
This is not really alarmist, and it seems that we have learned from a web-based “middle fair” that the false notion of “death to heaven” has made it difficult for these black-hearted walls to be completely eliminated, but, for a large brand, it is easier to understand why they should spend a lot of money on research and development to improve it, because these authentic brands have undisturbed factories that have to provide for them, so that brands must be of good quality and consumer interest。
