Harbin as a standard northern city, by the haze pollution is naturally quite serious, has been declared in a short period of time a number of heavy haze, the degree of pollution can be imagined. Harbin once focused on science and technology as well as industrial development also began to focus on the governance of the natural environment during this time, which governance of air pollution is the most important. Air pollution control is divided into many aspects, and the ban on the sale of bulk coal is one of them, many people may be less understanding of bulk coal, Bulk coal usually refers to some of the relevant departments to regulate as well as testing of bulk coal, this kind of coal and professional coal mines, not only the use of value is extremely low, and burning caused by the degree of air pollution is greatly increased.

Today's industry continues to develop and progress, people's quality of life has been significantly improved, but the accompanying is the continuous decline in air quality, in recent years, ravaged the north of the haze can be illustrated a lot of problems, which Harbin, although compared to the other northern cities slightly better, but still is the worst of the haze. Still is the worst haze area. The reason why Harbin recently banned the sale of bulk coal, the main reason is because of the nature of the bulk coal itself. We all know that once a commodity is out of the department's supervision, it is bound to have serious quality problems, loose coal belongs to this type of commodity, and loose coal in the strict sense of the word belongs to the inferior goods, the quality and safety issues are not as good as the other coal mines.

And as coal is freely distributed in the private sector, it was once not banned, which has resulted in poorer air quality in Harbin. The quality of loose coal is difficult to guarantee because it is not regulated, and it usually burns with insufficient heat and emits a variety of toxic gases, causing serious air pollution, which is strictly prohibited in the heavily polluted north of the country.

Nowadays, although technology continues to progress, the number of commodities continue to increase, but still need to pay attention to the quality of the goods themselves, especially loose coal this type of goods, once the negligence is likely to cause serious pollution , and Harbin this decision is undoubtedly made an example, I hope that other regions can also loose coal to a certain extent.
