According to the Guangdong Province Environmental Information Announcement Platform, the Pearl River Delta has seen a reduction of locations failing to meet PM2.5, with northern Guangzhou, Zhuhai, Shenzhen and Huizhou reaching outstanding levels. However, for the first time since the PM2.5 public monitoring announcement, a multi-day failure to meet PM2.5 limits resulted in Foshan’s Huijingcheng Station’s receiving a “red card”.
Conghua, Guangzhou’s Tianhu Station; Xiangzhou, Zhuhai’s Tangjia Station, Luohu District, Shenzhen and Huiyang District-Jinguowan, Huizhou were able to reach PM 2.5 concentrations lower than 35 micrograms/cubic meter over a 24 hour period, resulting in a rating of “excellent”.
In contrast, on March15th, the Huijingcheng station of Foshan’s PM2.5 concentration over 24 hours reached 127 micrograms/cubic meter, with an air quality rating of 172, resulting in a fourth degree “moderate pollution” level. The primary pollutant was PM2.5, and this was the first occurrence of any station within the Pearl River Delta region exhibiting “moderate pollution” levels since the announcement of public monitoring of PM2.5 levels. Huijingcheng station is located in downtown Foshan, where there are high levels of traffic and a high population density, attributing to the reasons why pollution levels have not been reduced. According to data from the Environmental Information Announcement Platform, air pollution occurs more severely in the western portion of the Pearl River Delta. Experts explain that the primary reason for high pollution levels is human activity in the area, followed by climate influences.
