Digital PM2.5 Air Quality Detector PM2.5 Particle Concentration Sensor Temperature Humidity Measure Wholesale Factory
Beijing successfully lowered air pollution levels following a crackdown on polluters last year, bringing China's capital in line with air quality targets, according to Chinese officials.
Reuters reported that the figures provided by the government agency were in line with the news agency's own estimates.
Despite meeting the target, northern China is still a ways off its official PM2.5 of 35 micrograms per cubic meter and even further off the maximum of 10 micrograms per cubic meter recommended by the World Health Organization.
"Current air pollutant levels remain a lot higher than the national air quality standard, indicating the improvement in air quality will still be a long-term process," Beijing's environment agency said.
PM2.5 is particulate matter with a length of 2.5 microns or less. Often a mix of chemicals, the microscopic cocktail of toxins from power plants, automobiles and other sources of industry harm human lungs and can cause heart problems if they enter the bloodstream.
To reduce air pollution, Beijing closed nearly 2000 factories in the cement, foundry and furniture sectors and shut down coal power plants in the past five years. The city also took nearly 2 million high-emission vehicles off the road.
In north China's drive to switch to residential winter heating systems, it began phasing out coal-powered boilers to switch to gas or electric-powered equipment. It also shut down or curbed production at heavy industrial plants.
