China Instrument Network News: In November last year, 104 cities across 20 provinces nationwide reached severe pollution levels, and "smog" became the headline in various newspapers. However, clean air is a major selling point of tourism in Sanya, making citizens proud. On February 18, Zhang Yun, a member of the Sanya CPPCC, stated in his proposal that Sanya must strengthen environmental protection, safeguard optimal air quality, and quickly improve Sanya's air monitoring methods.
Last November, Sanya experienced several consecutive days of PM2.5 above 60, even experiencing seven consecutive days of "mild pollution." Rumors circulated online about "smog" in Sanya, with media outlets competing to report on it. Although it was only a rare sight, the originally excellent air quality earned the nickname "fog" surprised local residents.
What exactly affects Sanya's air quality? Zhang Yun believes that pollutants blown in from the mainland are key to affecting Sanya's air quality. In addition, the surge in motor vehicle numbers and increased exhaust emissions are also contributing factors. Experts believe that air quality is increasingly affected by regional factors, especially the uncontrollable arrival of pollutants from other provinces. The biggest source of pollution locally is vehicle exhaust, which is the main culprit behind air pollution. Additionally, dust from urban road construction and construction sites cannot be ignored; Outdoor barbecues and cooking fume are quite hazardous.
How can we maintain optimal air quality in Sanya? Zhang Yun suggested improving Sanya's air monitoring methods as soon as possible. PM2.5 monitoring in Sanya has officially been in operation since January 1, 2014. Currently, PM2.5 monitoring equipment in China is standardized, but air composition varies by region. Using Beijing's instruments to monitor Sanya's air may not be appropriate. It is recommended to quickly develop a set of testing instruments suitable for local air quality conditions to ensure accurate and accurate testing.
Zhang Yun also stated that besides improving monitoring methods, environmentally friendly buses should be deployed to reduce pollution source emissions; Controlling the impact of urban dust pollution and managing construction sites: Sanya has consistently implemented provincial safety production standards; Conduct rigorous evaluations and formulate a compensation plan for the migration of mainland pollutants to Sanya.
