What harm does air pollution do to human health?

Harmony between man and nature is a long-term solution for sustainable development, but in fact, human activities are always affecting the natural environment, especially since the modern industrial revolution, the level of human productivity has been greatly improved, and the damage of industrial pollution to the environment has also been greatly deepened, which is an undeniable fact.

The main source of environmental pollution is industrial pollution to the environment, including waste water pollution, air pollution, soil pollution and other kinds of pollution, each of which will directly or indirectly affect human beings. As far as air pollution is concerned, it has many direct and long-term effects on human health.

There are many sources of air pollution, such as industrial waste gas, automobile exhaust and formaldehyde contained in furniture. There are many examples of direct effects of air pollution on human body. For example, when the concentration of a certain toxic gas reaches a certain level in the environment, people will be poisoned. The most common examples are carbon monoxide poisoning and hydrogen sulfide poisoning. We often see reports of this kind of gas poisoning in the news, such as carbon monoxide poisoning caused by gas leakage at home, and there used to be a strong pungent smell in rural toilets, that is, hydrogen sulfide, which can also cause gas poisoning and produce adverse reactions such as nausea and vomiting.

The indirect and chronic effects of air pollution on human health are more common. Nowadays, there are more and more people suffering from respiratory diseases. One of the important reasons is that the air quality is getting worse and worse and the air pollution is serious. People inhale harmful gases for a long time, which harms the respiratory system and leads to various chronic respiratory diseases becoming more and more common.

There is also a more common harmful gas, formaldehyde, which is ubiquitous in home decoration. Furniture such as sofas and beds contain harmful gas formaldehyde. The volatilization of formaldehyde is a slow process, which takes many years to volatilize, far exceeding the time from decoration to occupancy of new houses, so most people are inhaling harmful gases such as formaldehyde. This gas will not directly cause adverse reactions in the case of low concentration, but inhaling harmful gases such as formaldehyde all the year round will cause cancer.

In short, the impact of air pollution on human health can not be ignored, and the way to reduce air pollution is to plant more trees, improve the greening level, reduce the emission of industrial waste gas and strive to improve air quality.
