In the fight against air pollution in China appeared a dangerous side effect

Thousands of factories around the world daily pollutes the air of the planet with harmful substances, which reduce the life expectancy of people. It is believed that this problem is particularly acute in China - which is why in 2013 the country's authorities have decided to immediately clean the air of harmful particles. In just four years they have managed to achieve such results, which the United States sought for 30 years. Quickness is impressive, however, this approach has been identified side effect appeared in the air no less harmful to the body element - ozone.

In the fight against air pollution in China appeared a dangerous side effect

The work on removing harmful particle size of less than 2, 5 microns conducted from 2013 to 2017 year. During this short period of time the concentration of harmful to human health components decreased by almost 40%. Unfortunately, with the decrease in their number, in the air dramatically increased the concentration of other harmful living organisms substances - ozone. This was reported by researchers at Harvard University and the Chinese University, examined data of thousands of stations for monitoring air quality. The most dangerous for the health of the air has been found in Beijing and China. Chemist Daniel Jacob explained that the increase in ozone level is directly related to the decrease of the most harmful micro-particles. It turned out that they are well prevented the occurrence of ozone, absorbing part in its formation hydroperoxide radicals. It is noteworthy that before the scientists did not observe this effect, since no country has not taken such rapid steps to reduce the number of harmful micro-particles.

Scientists believe that China is moving in the right direction, but now the country has a new task - to slow down the formation of ozone. For this purpose, the authorities need to develop a new air pollution control measures and to reduce emissions of volatile organic compounds and nitrogen oxides. It is expected that this can be achieved died fuel burn - in the air stop-forming chemical reactions of ozone and the air will be cleaner.
