What is smog?

City dwellers are well aware of what smog is and how it looks. But few people realize that the word smog comes from the English words “smoke” and “fog”, which means “smoke” and “fog”. England has always been famous for its mists, and when the peatlands are still burning, one gets the impression of a continuous veil, hence the concept smog.

Smog concept

Now the very concept of smog is different from the ancient one and represents smoke, which consists of a mixture of nitric oxide with different impurities. In metropolitan areas and large cities, smog is a huge amount of car exhaust. This is especially noticeable in the morning at a short distance from the city and in windless weather. Then, it seems that the city is covered with a gray cloud, like a hat - this is smog.

Danger of smog

Everyone knows that smog is very harmful to human health, but not everyone knows what smog is dangerous.

Under the influence of ultraviolet particles of smog enter into chemical reactions, resulting in the emergence of new substances.City dwellers inhale them, and they in turn lead to various lung diseases: bronchitis, pneumonia, asthma, and even cancer. The lungs of a person who lives in a huge metropolis are not less covered with soot than an experienced smoker.

Oddly enough, athletes and children suffer most from smog. Light morning jogging or exercise in the fresh air will do much more harm than good. And children who play often on the street suffer more respiratory diseases, and the reason for this is smog.
