Since March 2, Taiwan has been affected by a wave of overseas pollution brought by the northeast monsoon. Starting from the northern and Yilan regions, it has significantly affected the central and southern regions by March 4. In addition, today (4) the large environmental wind field The wind turned easterly, the weather was stable, and the dispersion conditions in the western half were poor, making it difficult for overseas and local pollutants to dissipate. It is expected that it will not gradually improve until later tomorrow (5th). The Environmental Protection Agency has used air quality forecast information to coordinate power plants such as Taipower China Huo, Xingda, Xiehe and Liuqingmai Power Plants to reduce load and reduce emissions in advance starting from March 1. Local governments have also quickly implemented various emission reduction measures. and promote health protection to reduce the impact of the deterioration of empty products.

 

The Environmental Protection Agency stated that monitoring data from measuring stations such as Matsu on the outer island, and Fuguijiao and Wanli in the northern tip of Taiwan showed that the PM2.5 concentration began to gradually rise at 2 pm on March 2, with the highest value reaching 81 micrograms/ cubic meters, which belongs to the red hazard level. The pollutants are then gradually blown southward to the central and southern regions by weak northeasterly winds. Then they encounter stable weather in the western region, large temperature differences between day and night, dense fog and temperature inversion in the morning, making the diffusion conditions The deterioration has led to the accumulation of pollution in the central and southern regions, and the air quality has reached the red warning level. It is expected that from tomorrow (5th) to 6th, the central and southern regions will still be at the orange alert level and some areas may reach the red alert level in the short term. Other areas are expected to gradually improve.

 

The Environmental Protection Agency added that Taipower Corporation has carried out power plant load reduction and emission reduction in advance from March 1 to today. According to statistics, from March 1 to March 3, a total of 260 million kilowatt hours of power was reduced, with power plants in Taichung, Mailiao, and Hsing. Power plants such as Dajie and Xiehe carried out load reduction. The load reduction of each coal-fired power plant reached 10 to 40% of the daily power generation, which translated into a reduction of 91.5 metric tons of sulfur oxides, a reduction of 78.2 metric tons of nitrogen oxides, and a reduction of 2.7 metric tons of suspended particulates. , equal to the air pollution emissions caused by coal-fired power plants providing the electricity needed by New Taipei City (1.6 million households) for half a month. In addition, other counties and cities have also launched response measures, including vehicle and factory inspections and road cleaning. Among them, 6 counties and cities including Gaoping in Yunjianan launched the UAV Eagle Project to conduct open-air burning hot area inspections, and a total of 11 illegal cases were reported in Yunlin County; in Chiayi City, garbage incineration plants were required to reduce their loads; Tainan City launched Bright Clear Sky The plan, in addition to carrying out strain reduction, also suspended the use of leaf blowers to reduce dust.

 

In addition, due to the Taiwan-wide power outage on March 3, a total of 28 of the Environmental Protection Agency's 78 air quality monitoring stations were affected. After active recovery, all have resumed normal operations at 8 a.m. on the 4th. The Environmental Protection Agency reminds that the central and southern regions may still have orange alert air quality conditions for the next two days. It calls on all public and private places to actively reduce load and reduce emissions.
