Kunming will install air monitoring equipment in two locations – one downtown, one on the outskirts of the city – to keep an eye on the amount of airborne particulate matter, municipal environment officials told Kunming Daily on March 12.
The first two air quality monitoring stations will be set up at Dongfeng Dong Lu and Longquan Town.
The Kunming air quality monitors will be able to detect particles smaller than 2.5 micrometers, commonly known as PM2.5, which can penetrate deep into lung tissue and affect respiratory and circulatory functions.
American and UK medical authorities have documented a wide range of health problems stemming from PM2.5, including arterial plaque deposits, hardening of the arteries, vascular inflammation and increased risk of heart attack.
PM2.5 has served as a source of friction between the US Embassy in China and the Beijing government. The US Embassy's air monitor – which posts updated air quality data hourly via its Twitter feed - includes PM2.5 in its assessments, whereas municipal officials do not publish such data.
Exhaust from cars, buses and trucks is one of the most common sources of PM2.5. Recent municipal statistics show that the city was adding 1,000 cars to its streets each day.
A government tender has reportedly been issued for the air monitoring equipment, which is expected to be put into use by June of this year. No details regarding plans to publish PM2.5 data online have been made public.© Copyright 2005-2021 GoKunming.com all rights reserved.
