Beijing improves air quality by 2030

The Chinese environmental agency recently said that concentrations of polluting particles in Beijing's air are expected to fall to a safe level according to international standards by 2030.

According to Pan Tao, head of Beijing Environmental Protection Research Institute, PM 2.5 particle density in the air is expected to drop to no more than 35 micrograms / m 3 by 2030. This is the level safe according to the standards of the World Health Organization (WHO).

"Improving air quality in the city will not be an easy task. That process takes time and effort , " China Daily quoted Pan as saying in an International Conference on Urban Environment. in Beijing yesterday.

Beijing Environmental Protection Agency said the average PM 2.5 concentration measured in 2013 was 89.5 micrograms / m 3 . Beijing's rapid expansion, population boom and urbanization are the causes that hinder environmental improvement and control. High molecular dust density corresponds to low air quality, especially dangerous for the elderly and young children, people with heart and lung disease.

Air pollution is a topic of recent interest in China. Only three of the 74 cities monitored were air quality that met the standards in 2013.

In February, air pollution in the capital of Beijing was first classified as a yellow alarm group, the second highest level in the 4-step pollution warning system. Heavy air and dust pollution in many cities causes schools to cancel outdoor classrooms or even close their doors, vehicles must restrict travel.

Polluted emissions are exceeding the city's ability to handle, other environmental problems are likely to lead to dense dust in Beijing and many other cities.

Many companies, especially cement plants and coal-burning facilities, have been sanctioned for emissions exceeding permitted levels, lack of measures to reduce emissions or not to treat waste.
